Everyday we all look at images on screens and in print. Obviously, you are looking at one now. You may have wondered or not realised how these images are produced.
Below we explain the complex mixing of light on screens and ink on paper to create different shades, intensities and hues of colour.
RGB or red, green and blue are the primary colours of light used within computer monitors and television screens to make up full colour images. Images for use on screen should be saved as RGB files.
CMYK or cyan, magenta, yellow and black are the primary colours used in the print process when printing a full colour image. Have a look at your colour desktop printer and you will see the same colours used. Images for use in print should be saved as CMYK files.
