A method for color management and printing machine calibration

Abstract

The invention discloses a color control and printing press correcting method which comprises the following steps that a printing target and software and hardware in the printing process are selected; whether pre-press equipment and printing press equipment meet printing standards is detected, if yes, the next step is executed, and if not, equipment maintenance is executed; after linear correction, a first-version printing plate is printed; whether the size of screen dots of the first-version printing plate is accurate is detected, if yes, the next step is carried out, and if not, Ctp linear correction is executed; printing on the press is carried out to obtain a first print hand sample, the first print hand sample is detected, and if the first print hand sample meets the standards, the next step is carried out; a compensating curve is generated, and a second printing plate is printed according to the compensating curve; whether the size of the screen dots is accurate is detected, and if yes, printing on the press is carried out to obtain a second print hand sample; whether the second print hand sample meets the standards is detected, and if yes, printing is achieved and recorded. The products printed through the method are accurately matched with expected colors, and uniformity of the colors from beginning to end is achieved.

Description

technical field [0001] The invention relates to a color management and printing machine correction method applied in printing technology, and belongs to the technical field of printing. Background technique [0002] Color management is a method of combining software and hardware to automatically and uniformly manage and adjust colors in the printing production system to ensure consistent colors throughout the printing production process. Running color management generally includes three steps, device calibration, device characterization, and color space conversion. [0003] Equipment calibration refers to the calibration of the equipment used in the printing production process, the correction of process parameters, to ensure that the printing work is carried out in a stable state of the equipment; equipment characterization refers to the premise of calibration of the equipment, through various software and hardware tools Measure the color data and generate the color charact...

Problems solved by technology

[0004] At present, the commonly used color management methods in the printing process generally focus on equipment calibration. The lack of calibration in the whole process of the process makes the accuracy of the printed product and the expected color match low, and it cannot make the media of each equipment in different stages of the printing process Achieving color consistency on
