In this post, I will show you how to start printing press in Nigeria and make money from it. Printing press business is a lucrative and easy business that has a lot of huge returns.

The good thing about printing business is that you can start with a little amount of money as low as let’s say, maybe N8000 and have a huge profit within a space of one month. Although to get started, you will need two group of persons in this business.
The first is the graphic Artist which tackles every job related to design while the second is the printing press that handles the remaining rest by running sample impression as well as concluding the final printing.

How Profitability is Printing Press in Nigeria

Printing press business is a very profitable business. One can start the business with #6000 and within a space of one month, he will get his money back plus a lot of interest.

How To Start Printing Press In Nigeria

(1) First and foremost, have a business plan as it applies to all startup tips. Not only that market yourself. As a beginner no one knows about your printing business, you will need to make some self-advertisement by moving around various offices and firms to seek for printing jobs.
(2) Another tip is to have a niche in the printing industry, specialize in a given area instead of trying to be all things to all people. Success is more attainable by targeting a need and fulfilling it.
(3) Also, another tip is to familiarize yourself with business standards and, also, be careful with your words.

(5) The major concern should be customer satisfaction. It is only when that is achieved that you will see them coming back. Lose a customer and you will lose hundreds more.
Therefore, you can satisfy your customer by making sure you are working with a creative graphic designer. Having an awesome job done and fast delivery leaves a huge impression on your customers.

Technology Needed & Knowledge Needed to Start a Printing Press in Nigeria

Research the competition and their equipment.

Once you find out who your target market is, research the printing businesses who are currently attempting to fulfill the needs of this audience. Visit these printing businesses’ websites and learn all you can about them to find out what services they are lacking.
Draft plans to start your printing business by researching ways you can offer those badly-needed services and improve the printing business as a whole within your specific niche.

Research available printing equipment from manufacturers.

Once you determine what your competitors are using in their printing businesses, start looking to purchase your own printing equipment. You’ll need to find the highest quality, yet still affordable, equipment for your niche.
The wrong equipment can make or break your business. At the very least, you’ll need a desktop computer, some design software, and a high-quality digital printer that is able to handle jobs up to 11in x 17in.

Best Location for Printing Press in Nigeria

To start a profitable printing business, you’ll need to choose a location that works for you. Look for a place that is within your budget and that is easily accessible so customers will be able to find you with ease.
You don’t want anything to deter you from getting clients, and choosing a good location is a big part of that. You can look at locations online via realtor websites or hire a realtor to help you find the perfect location for your new printing business. 

Finance Needed to start Printing Press in Nigeria

Starting a new printing business will take capital amounting to several thousands of Naira. If you cannot finance this equipment on your own, contact your chamber of commerce to learn who can help you apply for a small business loans.
After you become established and have enough credit and show volume and potential, you might be able to lease equipment, which can bring flexibility, but leases may have penalties and balloon notes, etc. to return or to keep the item, respectively. 

Certification & Licensing Needed to start a Printing Press in Nigeria

This includes any licenses, certifications, permits such as a state sales tax permit. You will need fire department certificates, fire extinguishers and other safety equipment, safety procedures, safety rated chemicals, zoning, building use and occupancy permits and other items required for your specific operating location.
Even if you start a home-based printing business, you will likely need some kind of permit or license from your particular national, state and local governments. Call or meet with your local economic development agency to find out where to go next.
  1. You should familiarize yourself with Occupational Safety and Health Act (OSHA) requirements, including their and other agencies such as Equal Employment Opportunity Commission (EEOC) “postings” (required posters about safety and employment opportunity, etc.).
  2. Record keeping, tax withholding, reporting, and paying taxes and social security quarterly for employees (including part-time) are necessary.
  3. If you only use independent, outside printing contractors to do occasional printing that you cannot do personally, then you could be a “printing broker” (non-affiliated, wholesaler) and not have employees.
  4. Quarterly estimates of income, record keeping, reporting of actual proceeds, and paying your personal proprietorship or corporate (limited liability corporation [LLC]) taxes and social security for yourself is your responsibility to learn and complete each year.

Knowledge Needed/Training Required

The good news is that you no longer need long training to go into this business and gone are the days you’d need to get all your body stained with ink to get a printing job done!
he continuous improvement in technology has removed a lot of stress that getting a printing job out is just at your fingertips. All you need to do is to have the knowledge of the basic need.

In today’s part of our “How to” feature, I’m taking a look at the differences between colour models and modes. The idea is to explain to you how another central principle of producing print files works.
Choosing the right colour space is crucial to offset printing, and so in what follows, I’m going to give you some information that will help you to avoid unforeseen colour discrepancies on your printed products.

About RGB and CMYK colour models generally

The very first thing to mention is that there are two relevant colour modes: on the one hand, there is the RGB mode (red, green, blue), and on the other, the CMYK mode (cyan, magenta, yellow, key). The latter is the colour space in which your products will actually be printed – with offset printing, a plate is produced for each of the four colours using CTP (computer-to-plate), and each of these thin, usually aluminium plates, is then locked into the right printing cylinder and as the paper passes through the press, each of the colours required is overlaid onto the sheet. This means that each printed piece consists of four layers, and the end image is produced by what is known as subtractive mixing.
CMYK
CMYK colour model (subtractive colour mixing)
In theory, these three colours mixed together would be black. In order to get real black in printing, however, K (key) is used for details and contrast.
RGB is less about “real” colour than about the human eye’s perception of colour – e.g. our way of seeing colour on a computer or TV screen. In this model, the three primary colours red, green, and blue are mixed by light, which is called “additive” mixing. The overlap of the three colours leads to a range of different impressions of colour, and if red, green, and blue are added at the same level of brightness, the result is white; if green is missing, for example, then red and blue combine to make magenta.

RGB colour model (additive mixing)
This model is used to produce colour on monitors. If red, blue, and green pixels are all 100% bright, the result is a white screen.

Colour modes in practice

Most image sources (digital cameras, databases, etc.) offer imaging data in RGB mode, which makes it important to convert this data into CMYK mode for offset printing to avoid changes to colours. Given that the CMYK colour space is smaller than the RGB space, however, the offset printing process cannot reproduce all of the colours available on the monitor. The normal way around this is to produce ICC profiles for monitors, printers, scanners, etc., in order to try and offer a standard colour display on all input and output devices; professional graphics programs like InDesign or Photoshop also allow you to simulate the result with a good degree of accuracy. Then again, you need a monitor which can be calibrated, and you have to choose CMYK to print the product in any case
If you want to print areas, images, or even complete flyers in black and white, you’ll need to remember to save this files either as greyscale or in CMYK mode using the black channel only because if these tones are made up of cyan, magenta, and yellow, offset printing will give you dark brown or blue tones rather than proper black.

Spot colours

If you are preparing letters, business cards, or any other kind of business materials for yourselves or for your customers, then you will probably be required to keep to a corporate design of some kind. In most cases, specific colours needs to be used for things like logos or backgrounds, and they are supposed to look as similar possible on all media. If that is the case, you should definitely think about printing with spot colours, e.g. using the HKS or Pantoneclassifications.
HKS, which is very widespread here in Germany, is named using the initials of the three companies which came up with the system: Hostmann-Steinberg, Kast + Ehinger und H. Schmincke & Co.
A spot colour is a pre-defined colour tone which is given a unique name or number in the system catalogue, and using these spot colours allows you to print a tone outside of the possibilities of the four-colour printing system. This allows you to print highly-saturated colours or effect tones on a full range of materials.

When using spot colours, you should make sure that no other colours from the CMYK mode are overlaid – i.e. make sure that the overlay function is deactivated, otherwise your object could be hidden or the colour’s appearance modified. If you use spot colours in a print file without deactivating overlay, the finished piece could also have areas that are untidy or spotty, so try to use trapping rather than overprinting processes. With this level of complexity, when using spot colours, it really is essential to look at the print preview in your prepress file to make sure that there are no serious errors.

Most of you are no doubt familiar with the abbreviation CMYK already, but do you know what it is that makes this colour model so important within the printing industry? In this article, I hope to shed some light on the CMYK colour model for you by outlining the key things you need to know about this subtractive colour model.
CMYK colour model
CMYK is what is known as a subtractive colour mixing model. The basic colours used are cyan (C), magenta (M) and yellow (Y). In multi-colour printing, black/key (K) is added alongside these three chromatic colours to improve the contrast.

The CMYK printing method

During offset printing, all the colours being represented get transferred to the paper. Layers of coloured ink are placed one on top of the other to alter the light spectrum of the (white) printing substrate. In other words, less light is reflected/allowed through, which reduces the light spectrum (subtractive = reductive). The possible values for each of the four individual colours range between 0% and 100%. In each case, 0% equals no colour and 100% corresponds to full colour.
Within the printing industry, CMYK colour printing is called “Euroscale printing” and the term “Euroscale” is used informally (particularly in the USA) to mean European offset printing. However, the technically correct name for Euroscale is actually the standardised “ISO scale”. So that this standard can be applied appropriately in specific situations, we use what are known as ICC profiles, one example of which is the “ISO Coated sb” profile for printing on coated paper.
The use of four basic colours results in colour space “overdetermination” and so the basic colour of black must be defined for each CMYK colour space. The sharpest definition can be achieved by ensuring that none of the secondary colours involve combining more than three basic colours. This means that each secondary colour must either be defined using three chromatic colours (chromatic composition) or two chromatic colours plus black (achromatic composition). Other key colorimetric properties apply, depending on the separation method used, the paper and the printing conditions. There are probably at least as many CMYK colour spaces as there are potential combinations of the factors referred to above.
Compared to the RGB colour space, the CMYK space is relatively small, i.e. far fewer colours can be represented with this method than they can on a screen. Tones within the turquoise or orange ranges are particularly problematic. For a comparison of the CMYK and RGB colour spaces, kindly Search  this blog entry
.
To get a slightly clearer idea of the difference between the CMYK and RGB colour spaces, you can refer to the following CIE standard colour table. This CIE standard system was defined by the International Commission on Illumination (CIE – Commission internationale de l’éclairage) to establish a relationship between human colour perception (colour) and the physical colour stimulus involved (colour stimulus specification). It covers the entire range of perceptible colours. By referring to the CIE standard colour table, you can get some idea of how the RGB and CMYK models differ in terms of their scope.
CIE standard system - CMYK
To ensure high-quality printing results, the total for the individual colours must not exceed a specific maximum value. In this context, the maximum value depends on the paper, which can only take a certain amount of ink. Colour distortions can occur due to what is known as the “blotting paper effect”, which is when different types of paper absorb the ink to varying degrees even though the mixing ratios are exactly the same. For example, in the case of the coated paper that is frequently used in offset printing, a maximum limit value of 300% is recommended.

CMYK colour calculator

To avoid disappointing printing results, it is advisable to use colour calculators that convert RGB colours into CMYK colour mode. In the first instance, I would recommend using the onboard tools in Photoshop or Illustrator. Alternatively, there are lots of online and offline tools out there, some of which are available as freeware. One example is the Color Conversion tool.
You may also come across the term CMYKT. The T stands for topcoat, which is a special finish that is applied to the print to improve its properties in terms of light resistance, sheen and water repellency.

Today I would like to talk about what happens before the printing ink comes into contact with the paper. In this process the image is not placed directly on the printing material in one single step, instead it is put together from several component parts. This process is made possible thanks to 4 colour printing. You can now read about how this is defined, how the process works and what is understood by multi-coloured printing and spot colours.

Definition

Printers, which produce large runs of print projects, often use offset printing as digital printing is more suitable for the production of smaller print runs. Four-colour printing is the technique applied in all modern print processes for colour reproductions.
The basis for this consists of the four colours: cyan, magenta, yellow and key (black) – CMYK for short. Theoretically all colours can be mixed from the three subtractive primary colours cyan, magenta and yellow. So yellow and magenta make the colour red, while cyan, magenta and yellow make black. However, the colour pigments are insufficient, which is why just a limited colour space can be shown. Furthermore, the overprinting of cyan, magenta and yellow does not result in dark black, but rather a dark brown tone. For this reason, jet-black has been added as a fourth primary colour. In order to be able to print different shades of colour, different rasterisation is used, this means that many tonal values are shown through raster points of different sizes.

Process of 4 colour printing in offset printing

In order to print an image via an offset process, it must first of all be separated with the help of special computer software into the four primary colours (colour channels) of the subtractive colour model.
In the prepress, the artwork for each colour is individually rasterized and exposed on a separate printing plate. Therefore only the cyan, magenta, yellow and key (black) sections of the image can be seen on each plate. Up until a few years ago this exposure often took place indirectly via the conventional “Computer to Film” (CTF) process. However, this process has been replaced by the higher quality and time-saving “Computer to Plate” technique (CTP). The imaging in the computer-to-plate recorder takes place directly on the printing plate. In future this procedure could be replaced by the “Computer to Press” process.
For the flat printing process known as offset printing the exposed printing plates are fitted in the respective printing unit of the machine. The offset process uses the conflicting behaviour of different substances. This means that there are ink-repellent and ink absorbing areas on the printing plate. The ink absorbing (lipophilic, meaning water-repellent) image areas are differentiated from the image-free (hydrophile, meaning water absorbing) areas, which are ink-repellent through minimal moistening with water. Therefore the printing ink is only transferred from the ink absorbing areas on a rubber blanket, from where it is then pressed onto the object (paper) which is to be printed. The printing substrate is then layered with the colours cyan, magenta, yellow and key (black) one after the other, so that the complete printed image is created.
Example of 4 colour printing

Multi-coloured printing

The colour, which is created from CMYK during the print process, is known as the process colour. There is also the spot colour. These spot colours are defined by a number or a similar indication.
Special colours such as HKS or pantone are required, if a shade of colour needs to be 100% reproducible, so that the CI (Corporate Identity) of a company with logo, slogan or similar design elements look identical at any time, all over the world and can be recognised by the observer. This is extremely important for companies in order to position themselves on the market and to attract regular customers. For example, the shade of colour of a chocolate manufacturer can often be recognised from afar when shopping.
In order to always be able to adjust a certain colour, it requires a fixed special colour. Many companies of a certain market size bring their own colour guides with company colours they have created themselves for printing approval. The creation of this type of colour through the mixture of CMYK with other chromatic colours is possible, but often does not lead to the desired result, as each result deviates slightly from the previous result. The printing of spot colours is therefore carried out via multi-colour printing. As opposed to four-colour printing in this case 5 or more colour channels are set up depending on the number of special colours.
Depending on whether business paper, business cards or flyers for a one-off event or whether private greetings cards are to be given to a printer shop for completion, you should decide in advance which layout elements are to be produced and in which colours.

Web offset printing is the most frequently used rotary printing process and, in comparison with sheet-fed offset printing, it has a much higher printing speed. Here is some more information for anyone who has been wondering how very high print runs are managed. Well,  many of these type of printing are not common in Nigeria.

The basics of web offset

web offset newspaper printingPrinting in sheet-fed offset and web offset is an indirect flat printing process. It is indirect because the transfer of the colour from the printing plate first takes place via an additional roller (rubber blanket cylinder) and subsequently on the printing material. The term flat printing comes about because the elements which are to be printed and those which are not to be printed are found on one level on the rubber blanket.
web offset machine close-upFor printing machines used for web offset there is a difference between models which use a heatset and coldset procedure in the drying process which follows printing. The heatset process is used, for example, in the production of (advertising) brochures, catalogues and magazines, while coldset printing machines are used to produce newspapers and paperback books. In the case of these two types of machine we also often talk of commercial web offset and newspaper web offset. As with sheet-fed offset, there are usually four inking systems set up consecutively in web offset, while the paper web, unlike the individual sheets used in sheet-fed offset, is always printed on both sides. This perfecting printing process means that the paper web can sweep through the rollers and impression cylinders at speeds of up to 50km/h.

High speed printing

web offset machine in detailWeb offset is one of the most popular processes in the print industry. This is due in particular to the speed with which this type of machine can produce. These machines can achieve 65,000 cylinder revolutions/h and over. This makes them extremely economical, as millions of print product runs can be produced in a short space of time. The paper web is constantly processed by a roll and as soon as it reaches the end of one roll, if it is in operation, a new roll is directly attached.
Therefore the machines can run almost without a break, resulting in huge time savings. However, this high speed printing is only cost-effective for large print runs.

Heatset or Coldset?

As already mentioned, in web offset printing there are two separate variations. Broadly speaking the difference is in the drying of the paper web. Due to the fast speed of the machine the printing material must be supported in the drying process in order to keep the production process running.
The coldset process is used in newspaper printing machines. They have a vertical web lead and the drying takes place in a purely physical manner via the absorption of the colour. Drying in coldset web offset usually takes longer and results in black marks on your fingers when reading a newspaper.
In heatset web offset printing, the printing takes place via a horizontal web lead and with printing ink which has been dried through heat. After the final printing unit the paper web passes through the dryer. Temperatures of around 250 °C cause the paper web to be heated to around 120 °C. In the next cooling roller unit the paper is suddenly cooled to around 20-30 °C on chrome-plated roll surfaces, which results in a hardening of the ink. This brings about the typical heatset printing shine of the printing ink. Finally the paper is provided with additional protection in the form of a water silicone mixture. This provides the paper with moisture following drying and at the same time increases the scratch resistance of the surface.
Web offset heatset

Integrated processing

Unlike sheet-fed offset, there is the possibility to directly process the paper web in the web offset machine following printing and drying. In what is known as the folder superstructure the slitting of the paper web takes place along with the placing of the resulting part strands on top of each other. Then the first longitudinal fold takes place in the folder unit along with a transverse section of the collected strands. After this there is further folding of the sheets. These include the cross fold, longitudinal fold and the quarter fold. It is also possible to integrate longitudinal and transverse pasting, sizing, trimming edges and numbering in the folding unit.

Despite the digital age, print media are still extremely popular. Advertising in the form of flyers, posters and brochures are commissioned and given out in large numbers every day in Nigerian online print shops. The printing of large amounts of paper would be inconceivable without offset printing. I would like to talk about this print process, which we use daily, in detail in today’s article.

The definition of offset printing

Offset printing is – in comparison with letterpress printing – an indirect print process, in which the ink is not applied directly from the printing plate to the material which is to be printed (e.g. paper), but rather indirectly via a roller. This method is part of a flat printing process.

Historical facts about the print process

The definition and the process of offset printing has been shaped – as is often the case – by different people.
The Czech Alois Senefelder, inventor of the lithography printing technique, was looking for a cost-effective method of copying sheets of music in the 18th century. He used high pressure forms made of limestone, and he covered the areas which were to be printed with fatty printing-ink and the areas which were to remain free were etched with a slightly acidic solution made from polysaccharide (gum arabic) in the smooth stone surface. When moistening with water no ink remained stuck to the freshly etched areas. Therefore only the fat image areas were dyed. This fact makes etching to a high-pressure form superfluous. This discovery was the breakthrough and signified an important milestone in the principle of flat printing. It is still the basis of offset printing to this day.
In 1904 the American Ira Washington Rubel and the German immigrant Caspar Hermann constructed the first prototypes of offset printing machines independently of each other. They mirrored the indirect printing of the printing plate via a rubber blanket cylinder on the sheet of paper. When Hermann returned to Germany in 1907, he developed the first offset printing machine based on his plans, which was presented to the public in Leipzig in 1912.

Offset printing put into practice

As already mentioned, offset printing is an indirect print process. This means that in the print process a cylinder covered with a rubber blanket is set up between the printing plate and the paper. This is so the printing ink is transferred indirectly on the printed sheet. This ensures an even print, so that the same quality can be produced in high print runs. Unlike the lithography printing process described above, in offset printing the processes are largely automated. Instead of stone, millimetre-thin aluminium plates are used as the print template.
Before printing, a printing plate is created for each printing ink, so there is a total of 4 plates for the 4 colours C-M-Y-K. The image surfaces, which will later be filled with ink during the printing process or remain free, are placed on one level on the printing plate. Here the physical basis is the different surface structure, which comes about due to the exposure of the plates. This means that colour only remains where this is intended. Therefore there is a printing plate for each colour, as only the motif is exposed on the plate which is to be printed in the respective colour. The plates are then inserted into the respective printing unit (matching the colour) in the offset printing machine. The printed sheet passes through all 4 units after each other which results in all colours being printed on top of each other.
The actual printing takes place with the aid of three printing cylinders, which are identified in the diagram below with the numbers 4, 5 and 7. The prepared printing plate is stretched on the first cylinder, known as the plate cylinder, and absorbs printing ink from the inking system on the areas which are to be printed. The areas which are not to be printed are moistened with water with the aid of the rollers of the dampening unit, see No. 3 in the diagram. From the printing plate the right-reading image is first of all transferred back to front on a rubber blanket, which is fitted on the rubber blanket cylinder. Finally the reversed image is once again transferred to the paper the correct way round, which passes between the printing cylinder and the rubber blanket cylinder.

Distinction of offset printing

With regard to the use of the paper which is to be printed, there is a distinction between sheet-fed offset and web offset. While this process is suitable for the printing of newspapers, telephone books or catalogues in very high print runs, sheet-fed offset printing is used more for small and medium-sized runs.
When considering the development of the past few years it is clear that this type of printing has made a massive contribution to the simplification and speeding up of printing. It would be unthinkable to print newspapers, brochures or flyers produced in large print runs without offset printing Printing?
