The DIAMOND EYETM in-line quality control system for newspaper printing is the world's first automatic color matching process for color printing, that previously relied upon the experience and skill of the operator. This new technology, which compares target density data based on plate making data, and the results obtained by measuring the density of actual prints acquired by an image sensor on the printer and then controls the density, has made it possible to perform fully automatic, high quality printing from the beginning to the end of printing. This automatic printing capability produces uniform coloring at all times, thus greatly improving printing quality while saving energy and reducing costs such as less wasted paper. Mitsubishi Heavy Industries, Ltd. (MHI) are convinced that DIAMOND EYETM will become an indispensable digitized tool for rotary presses. Meanwhile, MHI would like to add that DIAMOND EYETM won the Technical Section Award of the Japan Newspaper Publishers & Editors Association, the Technical Award of The Japanese Society of Printing Science and Technology and the Technical Development Award of The Japan Newspaper Publishers & Editors Association.
