After running the CMYK Ink Zone Closed Loop System along with the X-Rite color scanning system for a few months, I have found how quickly and accurately the system can adjust my ink balance. Crossovers and PMS ink are not a problem at all. The competitor’s system we were using was expensive to maintain and its “time out” mode would delay me in between jobs  and make-ready. When Bill  came by to install the system from CMYK Distributors, he was thorough and his training was accurate, and it’s good to know he is a phone call away to help. He has a wealth of knowledge of the system and press we hooked it up to making the transition nearly seamless.
