My customers REQUIRE all our reruns of our labels to be the same. The color, the fonts, everything. Continuous reissuing of new versions of Illustrator makes this very time consuming and difficult. Most important, often our pressmen (with 50+ years of experience between the two) will not know something has changed until printed.
An industrial press uses about 12 feet of material before the first label even prints, making this a HUGE material and time waster in a busy print house.
Either fix your colors once and stop or tell us PRIOR to release of the changes so that we can set our machines. Once it's installed, we are screwed.
