Question

Percentages of color changing once file is saved

Hello,

My company runs Adobe Illustrator CS6 on all computers in our Art Department. We use CMYK color mode due to the fact that we are designing textile prints and always use spot colors. Often we will use percentages of those spot colors to achieve various tones. For reference we all work on the same server and save files as either PDF or EPS.

One of my designers is having problems with Illustrator changing the percentages 1-2% after she saves her files. She creates it at, say 50% of our black, then when another designer opens the file it has changed to 49% or 51%. If she opens the file and adjusts the percentage back and saves, it is again changed once re-opened.

I have no idea why this is happening. Any idea what is wrong or how to fix it?

If your document color mode is CMYK and the numbers are input in CMYK, they should not change, if you are saving as .ai.

If you save as .pdf then the values can change  unless you are set to no conversion.

Can you post a sample file even if there is just a rectangle file with color, and tell sue what settings you used.  Dropbox or any ftp link is what we use to post on the forums.

Hello Mike,

I have confirmed that she is working in CMYK mode and that our spot colors are also CMYK. 99% of the files we use are saved as EPS and the file I had her test was saved as an eps yet the percentage still changed once she saved it.

For reference we are both working on Macs so I don't think this has to do with computer incompatibility. This issue is also new (within the last few months) and had never happened on this computer before.

If you could post a sample file, that would be great. Would be easier for me than typing out 50+ questions as to what may have went wrong.

Also warned to remind you not to update your OS as CS6 stops working I believe at about El Captan, not sure about windows.
