Printing Color Error

Hi,

I sometimes experience an error when printing, and am trying to find out if the cause is the printer, software or file.

Th issue is that sometimes in a print, a specific color will print out in a different shade (or it will be de-saturated, or darker). This will happen in such cases as: 1) I've done a test print, and then print the rest of the job and the specific color comes out differently than before. 2) In the same print job, some of the logos will come out correctly, and some with a different shade of the same color. 3) Two different logos use the exact same color value for a specific color, but one comes out darker than the other.

It's not the same color every time either. For instance, there was an Orange that had the error, and now it is a Grey that has the error.

Has anyone experienced a similar problem, or know of a solution to this problem?
