Abstract

The invention discloses a method for obtaining the optimal solid density for coated paper printing. The method comprises the steps that 1, a CTP process control system is built, and the CTP device calibration work is finished; 2, a printer process control system is built, and the printer device calibration work is finished; 3, a printing test standard version is designed, a printing test is conducted through a standardized test method, and standard test specimen page is obtained; 4, data measurement is conducted on the density and chromaticity parameters of the specimen page; 5, according to the measured result, the optimal solid density for coated paper printing is calculated and obtained. According to the method for obtaining the optimal solid density for coated paper printing, on the basis of calibrating a CTP and a printer, the printing test is standardized, the eligible test specimen page is selected, the density and chromaticity values of a specimen paper designated color piece are measured, and a corresponding relation table for the chromaticity and density is built, so that the optimal density of the printed matter is rapidly determined, the defect that the optimal solid density is obtained through relative contrast is overcome, and accurate reappearance of color reproduction is achieved.

Description

technical field [0001] The invention relates to a printing process control technology, in particular to a method for obtaining the best solid density of coated paper printing. Background technique [0002] With the increasing demand for the quality of printed matter, the accuracy of printed solid density directly affects the quality of color reproduction and the quality of printed matter. For different substrates and different inks, determining the best solid density has become a decision in printing production. Key factors for quality levels and bottlenecks that need to be addressed. [0003] At present, relative contrast is mainly used at home and abroad to obtain the best solid density. There are problems such as long actual test cycle, high cost, and technical difficulty. Moreover, the obtained best solid density cannot determine the color difference between the printed proof and the standard proof. Therefore, the research and development of a printing optimal solid den...
