Heatset Web Printing | California Offset Printers

We specialize in helping publishers, catalog and commercial clients whose needs range from 10,000 to 250,000 standard custom products and formats. Our all-inclusive manufacturing facility and newest technology combines “big printer” operations, with personalized, small printer flexibility and hands-on service.

Our heatset web presses feature the new GMI Color Quick “closed-loop” color system. With this CIP-3 technology, the digital prepress files are used to preset the ink fountains. This technology enables us to provide vibrant and consistent color regardless of your publication’s run length.

More info:

Closed loop color control requires accurate information for each color at every ink key of the press, and ColorQuick delivers that.

ColorQuick’s on-web spectrophotometer measurement guarantees the most accurate ink density data for closed loop control, as well as Lab* color verification, true Status T or Status E density values, availability of colorimetric reports, and spectral and density data that conforms to graphics arts standards for SPC reporting.
