: Change of colour when copying into a different Illustrator document 1) When I am copying a logotype from one Illustrator document to another the colours are changing slightly. Anybody know why

@Kaufman565

If you are working in CS5 or older, but using a file from CS6 or newer, try this:

-Go to your "Swatches" window
-Click the options symbol in the upper right hand corner
-Select "Spot Colors..." from the drop-down menu
-Select "Use Lab Values specified by the book manufacturer"

This fixed my issue! I believe it's because CS6 and newer use only Lab color values while CS5 and older use Lab AND CMYK color values.

I was having the same issue, copying an illustrator logo from another designer into a print piece in cs6. I noticed that the 100y yellow changed to 100Y 49M orange. I am copying from cmyk to cmyk and my color setting for cmyk is set to ignore profiles and preserve numbers so this shouldn't be happening. Then I noticed that the donor file color swatches are all set as spot, but not pantone numbered just named. I double click on the swatch and set to cmyk and then uncheck the global box and that corrected the issue. When I copy the logo and paste, it now has the correct color.

Another note- if you do not uncheck the global box, when you paste the graphic to the new file, you will get a dialogue box saying "The Color Swatch "Name" has a conflict with the current document". Select add swatch and your image will paste correctly and it will add the swatch to the swatch panel.

Here's possibly what's happening:

Illustrator favors the pantone name over the CMYK values. So if the creator of the logo chose a pantone color, but then modified the CMYK values of it (by clicking on the swatch and switching from book mode to CMYK mode). The colors of that swatch are now different, but the name of the swatch is still the name of the pantone color.

Now if you copy that object to another document; Illustrator looks at the swatch associated with the color of that object and see the pantone name. It then gives it the value of the pantone color which is now different than the color it is on the original document.

So essentially it is no longer a pantone color, yet has the swatch name of a pantone color which "confuses" Illustrator into disregarding the new CMYK values in favor of the name.

1) Illustrator CS5 and CS6 must have the same color settings (Edit > Color Settings) for CMYK values to be the same. If you have mis-matched color settings, values will change.

2) Regarding Pantone colors, there is a marked difference between CS5 and CS6. CS6 uses the new Pantone Plus libraries which are built only on LAB values. Previous Pantone libraries were built on CMYK and LAB values. Check Adobe help pages for solutions to the pantone color issues. helpx.adobe.com/x-productkb/multi/pantone-colors-dont-match-illustrator.html Although it is best to adapt to the Pantone Plus libraries if possible. The difference won't effect printing, but it will alter the on-screen appearance.
