Designers actually gain some added benefits under this new approach. Since most designers today design for print and digital applications at the same time, keeping files in RGB gives you more flexibility as well.

Essentially, this means that the RGB colour mode creates other colours by combining or 'adding' different quantities of red, green and blue. For example, if you wanted to create a yellow colour, you would simply combine green and red. If you wanted to create a light blue colour, you would add green and blue. Obviously, it's a little more complicated than this and modern-day printers know exactly how to combine these colours in varying amounts to ensure that you end up with the exact colour you want.
This is the same for computer monitors too. RGB is the colour mode that is usually associated with computer monitors and other displays. Most cameras and digital scanners also use RGB. The reason that RGB is the standard colour mode throughout most applications is that it offers the widest selection of colours.
By combining the primary colours red, green and blue in varying amounts, you can achieve any colour you like with great accuracy. Most photo-editing programs use RGB as standard including Photoshop which is why you need to be extra careful when designing for print more on this later. CMYK works in an entirely different way to RGB as instead of using 'additive' types of colour, it actually uses subtractive colours i. Cyan, Magenta, Yellow and Key. Key is simply another name for black. The main difference is this; when you combine all the colours of the RGB colour mode red, green and blue in varying amounts, you end up with the colour white i.
With the CMYK colour mode, all of the colours are subtractive and therefore, the more colours you add together, the darker the colours are going to be. For example, if you add magenta and yellow together or more precisely subtract yellow from magenta , you end up with a bright red colour. If you were to subtract yellow and cyan, you would end up with the colour green. Clearly, this works in an entirely different way to RGB as the colour combinations are essentially opposite. Plus, CMYK works with four colours rather than three.
The reason the CMYK process works is that as you add colours together, light is absorbed or removed to create various colours. For example, if you add cyan, magenta and yellow together, you end up with a dark brown colour. It's only when you add the 'key' colour i. However, CMYK is still used by most professional printing companies so if you're looking to get something printed professionally, you need to be aware of this.
We've printed thousands of projects for hundreds of clients during our time in the printing industry and one of the most common mistakes we see is the lack of differentiation between RGB and CMYK. Many clients will create their designs intended for print in an application such as Photoshop which by default, uses the RGB colour mode.
This is because Photoshop is mainly used for website design, image editing and various other forms of media that usually end up on a computer screen. Therefore, CMYK isn't used at least not as default. The problem here is that when an RGB design is printed using a CMYK printing process, the colours appear differently if not properly converted.
This means that although a design might look absolutely perfect when the client views it in Photoshop on their computer monitor, there will often be quite distinct differences in colour between the on-screen version and the printed version.
One of the most noticeable differences between the two colours modes is the way that they present the colour blue. It is possible to do this by using software such as Adobe Photoshop Illustrator. You will need to convert these images to CMYK using something like Adobe Photoshop before saving and adding to your final artwork.
This ensures that any images placed in your file will be set to print as CMYK.
