What is CMYK

CMYK is a model that works with so-called subtractive colour mixing. Unlike rgb where adding colours creates paler combinations up to white, in the cmyk model we start with white and add colours to get to black.

The use of this model is mainly in printed documents where colours are created by mixing pigments. The basic colours are cyan, magenta and yellow and by mixing them, black is created. The cmyk model also provides for a separate black colour, as this is more economical and results in a richer and more beautiful black colour.

The principle of mixing colours in this colour model is much more like the work of a painter. The amount of shades produced by light is many times higher than what ink or toner can mix.

What is RGB

The RGB colour model is an additive colour model in which red, green and blue light are combined in different ways to reproduce a wide range of colours. The name of the model is based on the initials of the three primary colours, red, green and blue.

Today, RGB is the standard method for creating colour images on screens such as TVs, monitors and smartphones.

By the additive model we mean that by mixing all three colours we get white. If we do not add the colours, the result is black. If the intensities of the colours are equal we get a shade of grey, paler or darker depending on the intensity of the light emitted. If they are different we get a colour shade depending on the difference between the strongest and weakest intensities of the base colours used.

What is the difference between RGB and CMYK

CMYK is mainly used in printing where pigment mixing is involved. On the other hand, RGB spectrum colours are worked with in digital display, i.e. on a computer monitor. Therefore, graphic designs tend to be displayed in an RGB model on the computer in order to make their shades stand out. Of course, the more pixels a graphic design has, the more beautiful and better quality it is. Conversely, when we are about to convert such a design into leaflets, magazines, posters or billboards, we need to convert it into CMYK scale so that the printer can cope with the design. Failure to do so could result in a bland, faded print.

Change RGB to CMYK

The color conversion between RGB and CMYK is unidirectional. In case you convert the graphic from rgb model to cmyk you will cut off some of the brighter colors. However, if you wanted to convert the document back to rgb, the color scheme would not change since the CMYK colors are a subset of the RGB colors and the software no longer has information about which colors it should change.

Which software works with RGB and CMYK?

RGB and CMYK colour models are mainly used by graphics programs, which can be bitmap and vector. The graphic designer chooses the appropriate color model for his design and produces graphic files that can be used for web or print. The most well-known graphics programs where you can convert RGB to CMYK include Photoshop, Illustrator, Indesign, Inkscape, Corel or Gimp.
