As the number of solvent uses increases, the time for brushing the plate material should be appropriately extended; Adjust the position between the fine brush and the plate drum according to different plates, so as to adjust the pressure between the fine brush and the surface of the plate. If you make extra fine dots, you should further reduce the pressure of the fine brush on the basis of the standard thickness position to prevent the dots from being washed off. The drying temperature is about 50 ℃ and the drying time is about 1.5~2 hours; During the drying process, take it out several times to check whether there are solvent spots or other defects on the surface of the plate. Use a clean cloth that can not remove fibers, soak some fresh solvent, gently probe the surface of the plate, and then put it back into the drying oven to continue drying.
Flexographic printing machine
The plates after exposure and debonding can greatly improve the printability of flexographic printing machines. It is better to place the prepared flexographic plate for 12 hours before printing, so that the residual solvent absorbed into the plate during plate making can be completely volatilized.
In a word, in actual operation, the plate making personnel of the flexographic printing machine must closely cooperate with the personnel of the ink manuscript design, film production and printing departments, communicate with each other, and timely summarize the experience and lessons to improve the overall level of flexographic printing.
