Should I get the CMYK Guide set or the Color Bridge Set? It can be a difficult choice to make.
The CYMK system is is a different system to the PANTONE PMS system and so it does not relate to Pantone Spot colours.
Need the CMYK equivalent of Pantone PMS Spot colours? Then you should purchase a Color Bridge Set. This is ideal if your clients select PMS colours only to decide they want them printing digitally in 4-color process.
Color Bridges display the closest match to the Pantone Spot colours, the client can be advised on the expected outcome. They have squares of Pantone Spot colours with their RGB and HTML code, alongside squares of the closest match using CMYK inks and their percentages.
CMYK Guides contain a separate range of 2868 colours, they contain only colours which exist within CMYK colour space. These also give the ink percentages to enable confident use of 4-colour process colours in offset lithographic printing. If you only work with 4 color process, your clients can select colours from these guides with confidence that they can be accurately reproduced.
