The influence of plate making quality on printing effect

modern plate making technology is a digital high-tech plate making technology. In recent years, Jiangxi's plate making industry has achieved rapid development. For example, Jiangxi Mengda computer plate making technology and equipment have reached the advanced level of the same industry in Jiangxi. Japanese screen 7060 electronic color separation, German agfa36s Laser Phototypesetting, American G4/400 Apple Computer graphic image processing system, century rip cross platform output, the use of these hardware equipment and imported film, make the color plate making process enter the era of digitalization and scientization. In addition, the introduction of advanced offset printing equipment such as Manroland and Heidelberg in Germany has made significant changes in the quality of local printing of Jiangxi printing products: high image reproduction and reduction rate, high printing density, gorgeous colors, good printing effect, and unprecedented improvement in the accuracy of printing products

at present, there are still some gaps in plate making and printing between the mainland and developed coastal areas such as Guangdong. In color printing, sometimes there are inconsistencies in the design process, the color information between the screen processing results and the output proofing or printing results. In fact, this is mostly a problem of prepress plate making technology and process processing, The key to these problems is the huge market demand impact caused by the electronic division scanning reduction rate in the plate making process. Only this China Plastics Trade Fair has good points, clear layers, electronic color separation that is basically consistent with the original, plus image processing, stable printing and proofing, can we print good prints. Otherwise, no matter how high-grade and sophisticated printing equipment can make up for the congenital deficiency of plate making

to sum up, the deficiency is that our electronic scanning technology urgently needs to be improved. At the same time, the two control points of output and proofing should also be kept technically stable in order to improve the overall level of plate making. First, output quality control points. When PS files output film through laser Phototypesetting, in addition to the development, fixing, drying and other technical links, the most important link is to test the film output point. Through the transmission detection of the signal by the densimeter, adjust the technical parameters to achieve a clear point hierarchy and maintain a relatively stable zigzag experiment, which is mainly used to determine the zigzag strength limit of materials or components; The second is the proofing quality control point. Traditional proofing adjusts the ink volume according to the feeling of the thickness and intensity of the ink color by visual inspection, but stable printing proofing must use the reflection detection of the densimeter on the plane signal strip to achieve the data regulation of the ink volume, so that the color hierarchy and points tend to be moderate and remain relatively stable

based on the control of these two technologies, electronic scanning constantly explores, analyzes and summarizes, processes different image effects with different technical data, and pursues the best. It can also promote the technical improvement of this weak link through training, communication and introduction, solve the problems of insufficient original (image) restoration and flexible application of color perception and image color separation data processing, so as to keep the color and information between the original design intention and the printing results consistent. To sum up, on the basis of advanced hardware equipment, the introduction of advanced first-class skills and modern management concepts has become a new challenge for the industry. The improvement of plate making technology will have a direct impact on the printing effect
