As a kind of environmental protection printing, flexible printing has developed rapidly as people's awareness of environmental protection has been increasing. However, early hand-engraved rubber plates can no longer meet the higher printing requirements such as more visualization, leveling, and exquisiteness required at the present stage. In 1973, the DuPont Company took the lead in the development of cYreL (Silicon) photosensitive resin flexo. This version has a high elasticity, high resistance to print, high image resolution, make up for the deficiencies of the rubber plate, so this resin version has gradually replaced the rubber plate. Of course, to produce high-quality printing plates, high-quality plate-making technical personnel must also cooperate with high-grade flexible plate-making equipment. The purpose of this article is to discuss the flexible platemaking process. Let us first introduce the technical features of the flexible platemaking machine by taking the KMY type flexible platemaking machine as an example.
First, the flexible platemaking machine KMY flexible platemaking machine set exposure, washing, constant temperature drying, post-processing four processes in one. All production procedures are controlled by microcomputer components. Accurate data, high accuracy, and simple operation. The device functions as follows:
1. Exposure: The use of imported special plate lamp as exposure light source to ensure the stability of the light source.
2. Wash plate: use two-way automatic washing plate, wash plate brush fine, good stiffness, can produce 150 lines / inch dot version and relatively fine lines and small text.
3. Bakeplate: It has an automatic thermostat to make the heating even and effective.
4. Post-processing: The use of imported Philips in addition to sticky tubes mixed exposure lamp, saving time and improve work efficiency. Second, the flexible version of the plate making process Flexo plate version of the process is: manuscript → film (female) → exposure → rinse → drying → post-processing.
1. Original: The manuscript for flexible printing should have the following characteristics:
1 more colors, but less overprint;
2 does not require reproduction of particularly small details;
3 The network cable is not too high, but the design of the color printing effect can be obtained.
â‘£ can be processed online for packaging design.
2. Film (female) flexo platemaking film has the following requirements:
1According to the needs of plate making, graphic and clear, size and size specifications are accurate;
2 use frosted film;
3 Films require that the density of the four corners be the same;
â‘£ use of membrane in the CNS;
⑤ measurement with a transmission densitometer, white median concentration of less 10g0.06; 10g3.5 concentration than the black level. (to be continued)
