    Posted: 29 Oct 2015 at 11:54am
When I check my completed PDF print data in the Output Preview of Acrobat, dependening on the selected simulation profile
different percentages in the CMYK colours show up. It may happen that also a pure black (eg. for a QR code) is suddenly resolved in CMY.
How can that be? Are my defined colour in Illustator colours not definitive and final?

Which simulationprofile do I havr to select in order to see the values of the colour exactly the way my customet set them up in the first place?

Thank You

Hello Schikagga, 


Different CMYK profiles have different values for each channel (CMYK). For example, the color profile US WebCoated SWOP will have different values than Japan Color 2001 Coated. In some instances the values may not be that far apart, but still they values will not be identical between one profile to another. 

In order to match the CMYK percentages of your Illustrator file with that Acrobat's Output Preview, you have to select the same profile you used in your Illustrator file with the same profile in Acrobat's Output Preview profile dropdown menu. 

Illustrator's preference settings should be able to tell you the default profile being used - in most cases it is US WebCoated SWOP for CMYK. See if this link helps determining the profile you are using in Illustrator:

You can embed a profile into your Illustrator file to ensure that applications in your downstream process will know exactly what profile to use. You can refer to the "Embed a color profile" section in this link:

Hope this helps.
