RGB or CMYK, full colour printing?

Brochures: printing service in sheffield

At some stage your computer RGB file must be translated to CMYK in order to print it on a full colour printing press. That includes all type, all blocks of colour and all photographs. While most computer users get used to working with colour through RGB (monitors are set up this way), colour printing works through a different set up, CMYK (Cyan, Magenta, Yellow, Black). This is “4-colour process” or “full-color” printing that comprises the majority of leaflets, posters, brochures, magazines and marketing materials you see every day.

Converting from RGB to CMYK using popular computer programs:


Microsoft Publisher 2000

Microsoft Publisher defaults to RGB, but it is easy to convert everything to CMYK full colour.

Use the following menu options: Tools/Commercial Printing Tools/ Color Printing and select Process colors (CMYK). Please note that all images incorporated into a layout need to be linked and not embedded in order to maintain the CMYK color space within the image.

Using the following menu options does this: Tools/Commercial Printing Tools/Graphics Manager and highlight the embedded image. Click Link and click Browse to locate the original file and link to it. You will then need to send both the images and the layout file to us for printing.
