How to deal with the CTP problem of scratching?

 

Because the amount of sensitive layer of CTP plate is around 1.6g/m2, less than the traditional one, and most of them don’t have specific protective layer, it's worse than the traditional version in terms of scratch resistance. As a result, Should pay more attention on using standardized operation, a lot of times the user do not pay attention to when using the operation, such as take the version from the box directly to release out, not even the backing paper to take out the box together, make the layout of injured when lift, some no scratch before development can see, after the development is not very easy to find, by the time the computer sampling and found again, already waste a lot of manpower material resources.


Solution:

1.       Moving the plate--- very small white line, location is not fixed, in field site easy to find, most typically make 1 ~ 4 cm in the middle of the edition, because this position of just and version box of friction, easy to cause scratch paper backing solution is joined, or the whole package version from the box out on the rack, edition of avoid pulling.


2.       Pulling the plate----also the very small white line, in field site easy to find, most typically make 1 ~ 4 cm in the middle of the edition, because this position of just and version box of friction, easy to cause scratch paper backing solution is joined, or the whole package version from the box out on the rack, edition of avoid pulling.


3.       Plate cut - if you don't pay attention to developing machine cleaning and maintenance, on the rubber roller have crystal, the crystal will leave short scratches on layout, and sometimes no solution is hard-working, weekly (up to two weeks cleaning) the developing machine.
