Printing adjustment system and method

Abstract

A printing adjustment method includes providing a plurality of solid and screened density values produced by a proofing device that represent intended density values. The method also includes providing a plurality of solid and screened density values produced by a press output device. The method also provides calculating, in response to selected ones of the plurality of density values produced by the press output device and selected ones of the plurality of density values produced by the proofing device, required percent dot values to be used to print on the press output device a plurality of adjusted density values that approximately correspond to the intended density values. In a particular embodiment, the plurality of solid density values produced by the press output device are varied approximately linearly in density along a first axis, the first axis approximately perpendicular to direction in which output of the press output device is produced.

Description

technical field [0001] The present invention generally relates to the field of printing, and more particularly, to a printing adjustment system and method. Background technique [0002] Full color printing on offset presses has become quite reliable and affordable for customers long accustomed to black and white or printing with only one or two pre-mixed microparticle inks. This type of printing utilizes photochemical printing to reduce an initially multicolored material to the four basic colors used in printing. For example, printed color images combine four primary colors in varying shades—magenta ("M"), yellow ("Y"), cyan (" C") and black ("K"). In fact, accurately printing a color image to customer satisfaction is often tedious, problematic and time-consuming at times, since it often requires human intervention. For example, traditional four-color process printing generally utilizes a printing press that is only designed to apply or not apply individual quantities of ...

Problems solved by technology

In addition, these methods require a relatively accurate reference point, such as the center of the printing press, for the interval measurement of the color sample points

As a result, these methods can consume valuable resources in providing adjustments to reservoir zone control

Such an approach requires a significant amount of time and may also be subject to errors resulting from these setup procedures
