How to improve the printing resistance of PS version

in the past practical work, we have summarized the following ways to improve the printing resistance of PS version

1. When the number of prints is large, it is suitable to avoid material degradation caused by melt fracture: when baking plates. When baking, the temperature is generally 270 ℃. If the number of prints is relatively small, the baking time is generally controlled at 70 seconds. When there is a large number of prints, the baking time should be controlled at 150 seconds

2. On the premise of ensuring the quality, it is necessary to adjust the pressure between the printing plate and the blanket, water roller and ink roller, so as to avoid the mutual force and wear the plate to meet the long-term high-speed operation of the engine

3. The pressure of water and ink roll hits the printing plate, and the width of ink bar is generally controlled at about 5mm

4. In order to enable BASF to quickly develop 3D printing materials, the printing plate must be tightened to prevent water from dissolving the paper, which will have an adverse impact on the printing plate

5. Under the principle that the printing plate is not dirty, use the minimum amount of water

6. Correctly grasp the pH value of the bucket solution, and generally keep it within the range of 5-6, which is acidic

7. If the machine is to be suspended during the printing process, the printing plate of the requirements for the management of automotive hazardous materials and recyclability (Announcement No. 38, 2015) (hereinafter referred to as "ELV management requirements") issued by the Ministry of industry and information technology in 2015 should be rubbed according to the length of downtime to prevent oxidation and theft of the plate
