RGB vs CMYK

RGB and CMYK are two different colour models used in digital printing, and understanding the difference between them is essential to achieving accurate and high-quality prints.

RGB stands for Red, Green, and Blue, and it’s the colour model used in electronic displays, such as computer monitors, televisions, and mobile devices. In RGB, colours are created by mixing different amounts of red, green, and blue light. When all three colours are combined at full strength, they produce white light, while when they are completely absent, they produce black.

On the other hand, CMYK stands for Cyan, Magenta, Yellow, and Black, and it’s the colour model used in printing. In CMYK, colours are created by layering different amounts of cyan, magenta, yellow, and black ink. When all four colours are combined at full strength, they produce a muddy brown colour, while when they are absent, they produce white.

So, what’s the difference between RGB and CMYK, and why does it matter for printing?

The main difference is in the way colours are created. RGB is an additive colour model, meaning that colours are created by adding light. CMYK, on the other hand, is a subtractive colour model, meaning that colours are created by subtracting light from white paper. As a result, the colours that can be reproduced in RGB are much brighter and more vibrant than those that can be reproduced in CMYK.

This is why it’s important to convert RGB files to CMYK before printing, to ensure that the colours in your print match the colours on your screen as closely as possible. When RGB files are printed in CMYK, some colours may appear duller or darker than they did on screen, and some colours may not be reproducible at all. By converting your files to CMYK, you can get a better idea of how your print will look and make any necessary adjustments to your design to ensure that the colours are accurate.

In summary, RGB and CMYK are two different colour models used in digital printing. RGB is used for electronic displays, while CMYK is used for printing. RGB is an additive colour model, while CMYK is a subtractive colour model. To ensure accurate and high-quality prints, it’s important to convert your RGB files to CMYK before printing.
