CMYK-RGB conversion using ISO Coated v2 300% (ECI)

From annawiki

Proposal

Create a mapping list for easy look-up and import into a database. Use steps of 5 for CMYK. For CMY use 0 to 100, i.e. 21*21*21 = 9261 variations. For K use 0 to 20, which covers all but one case in the lists at VBB public transport colors. That is 46305 variations.
