CMYK COLOUR CHANGING???

Apr 2, 2012 2:50 AM

Tags: #cmyk

I am preparing artwork for a CMYK printer.  This artwork contains a particular shade of red: C0/M86/Y64/K23.

 

……However for some reason Illustrator has changed some red objects (not all) to different percentages, i.e. C17.95/M90.33/Y74.97/K6.18

Why has Illustrator changed this, any why the odd decimal points????

 

Any help would be very must appreciated, Thanks.

    gaagaa,

     

    It sounds as if you have Document Color Mode RGB instead of CMYK in the original document.

     

    Note that when you change, some colours are bound to change

    When using the eyedropper, do you also press shift to pick up colors? In that case the color will be processed by color management.

     

    The eyedropper is a different concept in Illustrator than in Photoshop.

    You need to use the shift key when picking up colors from images, gradients or meshes (for instance)

     

    But the picked colors will be processed by color management and will probably be altered.

     

    So using the eyedropper this way is dangerous.

     

    You should read in the manual about color mangement and about the eyedropper and about how color and other appearances are treated in vector graphics and Illustrator .
