Below is a range of information about prepress and the services, technicalities and activities carried out within it.
Prepress is defined as: ‘Of or relating to typesetting, page layout, and other work done on a publication before it is actually printed.’
RGB & CMYK
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.
CMYK or cyan, magenta, yellow and black are the primary colours used when printing a full colour image. Have a look in your colour desktop printer and you will see the same colours used.
