Understanding Colour

Nearly all scanners or digital cameras create images using three colours: Red, Green and Blue (RGB), these are the colours by which computers display images on screen also known as the ADDITIVE PRIMARY colours. Printing presses however, print full colour using SUBTRACTIVE PRIMARY colours...

 

plus (generically called CYMK).

All colours used in files for printing must be CYMK.

CMYK
This diagram illustrates how Cyan, M agenta and Yellow colours added together give black.
In practice an extra Black (K) colour is added to enhance depth and for sharper text

RGB
This diagram illustrates how Red, Green and Blue colours added together give white.
RGB is the method used for computer screen displays

Converting to CMYK: You will have more control over the appearance of your artwork if you convert all images from RGB to CYMK yourself. If we receive RGB images, we do a standard conversion to CYMK in PhotoShop. When the RGB colours are converted to CMYK some change (usually “dulling” can occur) The resultant colours may not be exactly to your taste. If you make this mode change prior to supplying your graphics you may be able to adjust the settings to something you prefer.

Please take the time to prepare your files properly, we want you to be happy with your job.

We cannot be responsible for below par results if you supply low-resolution or RGB images.
