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

==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.

==Comparing two data sources==
*1 = http://www.codecrete.net/CMYK
*2 = OSM Berlin/Sebastian [https://lists.openstreetmap.de/pipermail/berlin/2013-May/000621.html]
