Printing roller maintenance experience:
(1) Before each day of work, the operator of the printing press should clean the shoulder iron (roller) of the plate cylinder and blanket cylinder.
(2) When changing the blanket, clean the surface of the rubber roller with pure alcohol, gasoline or car washing water, then dry it with a cloth, and finally add RESOST7-3 anti-rust oil on the surface of the plate cylinder and the rubber roller with a cotton cloth or brush. Add two times in succession and leave for 5 minutes to dry.
(3) The backing paper used in the plate cylinder and the blanket cylinder is soaked with oil and then dried and reused, so that the use effect is better, or the film can be cut to an appropriate size with an appropriate thickness.
Several solutions for bill printing inaccurate:
The factory is the main printing unit for the printing of tax invoices in Hebei Province. Due to the fact that the printed products are mostly 3-6, and the quality requirements are high, several overprints must be accurate. In the past, the proofs were printed on the machine that first started printing, and the other machines were printed as such, but the phenomenon of inaccurate printing of several joints often occurred, causing a large number of products to be stapled. In the work of the author, I summarized the methods of unifying the regulations and regulations to solve the problem of unacceptable overprinting in the printing of bills, so that needle binding does not occur, and the quality and output are greatly improved.
Specific methods: 1 unified side gauge: 3mm design of the H line on the plate, the H line by the edge of the paper is 0.5mm thick, printing it just with the edge of the paper register. 2 Unify the former rules: When printing the same product, make the former rules consistent, and the operators should print strictly according to the same size.
Hard material scratch plate processing:
When printing large quantities of prints, every time you print 3,000 pages or load paper, you need to clean the plates and blankets. Sometimes a hard object is caught on the cloth cleaning the plate. If it is not noticed, the plate will be marked with a line of dirt. Heavy printing, wasteful work and mistakes are wasted; the use of revised pastes cannot be repaired because the dirty marks are not coated with photosensitive adhesives.
Treatment: Clean the paste with a clean cloth, apply a little dampening powder, and gently wipe it on the dirty mark. When you turn on the machine, you first give the plate water and idle several times, and then you get off the ink roller. The dirty mark disappears.
From this we can see that do not underestimate the importance of rag cleaning.
