ABSTRACT

In ‘Digital Negatives for Contact Printing’, we introduced a precise and repeatable digital-to-analog process for the perceptual conversion of monitor images to photographic prints, using halftone negatives. This process has the remarkable property of being consistent between pre-press offset printers, and is also largely tolerant of paper characteristics, as well as exposure and contrast deviations. For these reasons, we are able to suggest accurate starting points for hardware calibration, which will work without modification for all readers who have access to this type of equipment or an old-style service bureau.
