CMYK & RGB Colour Models for Print & Digital Design


CMYK vs RGB for print and digital

If you are familiar with working with digital or print design, you will probably be aware of the different colour models to utilise. RGB is an additive colour model, which means white is produced by combining all the primary coloured lights and black is the absence of light. CMYK is however a subtractive colour model and refers to the ink colours Cyan, Magenta, Yellow and Key (Black).

Cyan, Magenta, Yellow, Black

The CMYK model works by partially masking the colours on a lighter, usually white background. The ink, which reduces the light that would have been reflected, therefore ‘subtracts’ the colours red, green and blue from white light. This distinction between the models makes the RGB prefect for digital and CMYK ideal for print; CMYK sometimes refers to the printing process itself.

However, the range offered by RGB (its colour gamut) is larger than that of the CMYK which explains why sometimes although you design looks good on screen in RGB, the CMYK usually lacks vibrancy. Also, some colours cannot be reproduced using CMYK. As a result your print out may look a little muddied. If you are a professional photographer for example, this is obviously not the result you want.

Many constraints exist when trying to achieve the reproduction of colours that are perceived by the eye in nature. However, there are many printing processes that have be devised such as offset and lithographic printing processes, which though are still in development, already produce a more natural look.

One good advice is to make sure you only work with colours that can be printed (that is, within the CMYK gamut). For example if you are working in Photoshop, you can opt to work in the CMYK mode. However, with today’s wide format printers that have 12 ink colours, you may be able to achieve a spectrum closer to that of RGB. Canon’s imagePROGRAF PRO printer range has good options for this. You can buy printing supplies for these printers in the InknTonerUK website. Ideally, if you are concerned about the colours looking good you would opt for original inks. But, this can be very expensive, so we provide you with multipack options which will give you great savings. For example, we sell multi-packs for the imagePROGRAF PRO-1000, imagePROGRAF PRO-2000, imagePROGRAF PRO-4000 and more.


Busting the Myth that Printing is not Sustainable!


Printing is sustainableThe digital revolution has meant a switch over to non-paper-based communication, increasingly reinforced by penalties and supplementary charges for using paper. But has misinformation been the driving catalyst for this change? Did you know that one of the main reasons companies want to shift to electronic delivery is to save money and not necessarily be environmentally responsible. It is a well-known fact that people understand, retain and use information better when in print on paper, and paper is in fact sustainable when consumed responsibly. For example, double-sided printing in the office and collection schemes will reduce costs as well as improve sustainability. There are software packages available such as GreenPrint that isolate blank pages for example, thus reducing the number of binned sheets of paper. If companies want to save money, then investing in a printer that takes compatible cartridges easily is a good idea (most printers do). As it is often the cartridges that add to the running costs of printing, knowing your cartridge options for your particular printer becomes of paramount importance. You can search for cartridges by navigating using the make and model of your printer on the InknTonerUK website on the quick search toolbar.

The European paper industry recycles at the rate of 72% (2016 figure) – and with recycling collection systems improving this rate is set to increase. As you know, the main raw material is wood; if harvested in a carefully controlled and sustainable way, it makes printing a sustainable industry. In some countries, in particular, in the tropics, the conversion of forests to industrial plantations is a cause for concern, but that is not the case in Europe where most of our paper is sourced. In fact, European forests have increased in size by an area the size of Switzerland in just ten years. The paper, pulp and print sector is one of the lowest industrial emitters or greenhouse gasses, accounting of 1%of global emissions. And with many customers still valuing paper-based communication, it might be wise to not go entirely digital.

If you want to print in an environmentally friendly manner, but worry about the quality of your prints, rest assured that buying remanufactured cartridges from a trusted vendor like InknTonerUK would guarantee that your remanufactured cartridges would perform as well as a new cartridge. Look our for the pink ‘premium’ label on the products on the site for premium remanufactured products. Compatible cartridges on the other hand are great value alternatives for everyday use.
