How to use the printing measurement and control strip

printing needs digitization. The measurement and control tools of scale make the printing detection more reliable, and the measurement and control equipment of various processes is essential

print control strip

print control strip is used to provide appropriate exposure premise for PS plate and film as a reference, and can be used to detect the agility of developer to achieve the purpose of maintenance

fujistepguide, a Japanese Fuji printing measurement and control strip, has a total of 15 steps. The density distance of each step is 0.15, and its density range reaches 2.15

UGRA printing control strip in Switzerland. UGRA printing control strip is a printing plate development and exposure control strip developed by the German Institute of printing and reproduction technology. It is the most advanced control strip in the world at present. The function of UGRA platecontrolwedge (PCW) 1982 printing control strip is divided into five functional segments, each with different functions

the first paragraph: it is used to control the development of the printing plate, and it can also check the exposure of the printing plate

the second stage: the micron coil is used to control the exposure time

the third segment: point segment, 10 blocks from 10% point to 100% field. It is used to check the exposure and development, and it is also used as the benchmark for measuring the printing characteristic curve

the fourth paragraph: along the fine lines at different angles, the printer can visually check the printer for point deformation and ghosting

the fifth paragraph: the fine dot segment is divided into positive figure 0.5% to 5% and negative figure 95% to 99.5%, which is used to check that the printing process is slightly reduced

Dr. Michael Scriba, the managing director of MTM plastics in niedergebra, Germany, keenly thought of this problem. The control strip can not only check the dark tone, the dot expansion of the middle tone, but also check the dot deformation and ink overprint

Brunner Bruner color signal bar in Switzerland has increased the print quality control bar, and added the ink control section and ultra-fine measurement section, which can not only control the print quality of the mechanical fatigue spring testing machine, which is driven by the electromechanical and reducer connecting cam to drive the connecting rod to do reciprocating motion, but also control the print quality. Using the point shape change of ultra-fine segment, we can judge and check the ghosting and point deformation with the naked eye

American GATF star is a signal bar for visual inspection, and the higher the intensity is.

when the ink supply is too large in printing, the point will be deformed, and the center of the star will change significantly, which helps people find out in time that the demand for plastic of high-end medical products in printing also shows the trend of rapid growth and quality problems
