CMYK color space?

I open an EPS file containing a company logo (using Illustrator), and see that the color they used is described as C,M,Y,K values in percentage. But I don’t see any kind of color space attribution.

Does CMYK always use the same definition, at least for this kind of print work? With RGB there are different color spaces to choose from and the numbers don’t mean much without knowing which space they are noted in.


CMYK is the same as RGB the space should be declared*. Unlike RGB, where you can assume sRGB, there is no one space in CMYK you can assume to hold true. There are some regional standards which you can guess. But without this info we will never truly know what was meant by the color without asking the author or last printer.

* In fact all color declarations have this property, except cie xyz and cie Lab. Simply values have no fixed meaning without colorspace declaration
