How to resolve 8 kinds of common trouble in plate making process
From;    Author:Stand originally

1, forme blank ministry to jam breakdown reason reachs a processing technique:

① carries time of exposure on the back to grow too, should notice proper control carries time of exposure on the back;

② advocate overexposure, below the premise that assures emersion small character, fine line, shorten as far as possible advocate time of exposure;

③ edition material and film contact are undesirable, should make sure vacuum system works normally, use the air between material of roller drive edition and film.

2, small site, small character, fine line is washed breakdown reason and processing technique:

① carries time of exposure on the back insufficient, should consider to add a back time of exposure;

② advocate time of exposure is insufficient, can increase advocate time of exposure;

③ is washed edition time grows too or wool brushs pressure too big, should notice to shorten wash edition time and adjust wool brushs pressure.

3, reason of breakdown of complete sclerosis of forme bottom unfinished and processing technique:

① carries underexposure on the back, add a back time of exposure;

② is rinsed not complete, have the colophony keep with not sclerotic remains, examination wool brushs pressure and adjust wash edition time.

4, wash edition deepness with a forme abhorrent breakdown reason and processing technique:

Machine of ① printing down is too hot, microscope is ventilated reach cooling system to whether be put in breakdown;

Intensity of lamp of ② printing down inhomogenous or open is not synchronous, all tube changes in the meantime;

③ washs edition wool to brush not parallel or the movement is lopsided, adjustable wash edition wool to brush pressure and level to spend.

5, image part is punch-drunk breakdown reason and processing technique:

① film has drawback, the picture on microscope film is clear;

② fault uses offset print film Yu Rouyin, what make qualification afresh is soft imprint film.

6, when pressworking, small site loses breakdown reason and processing technique:

① advocate or carry underexposure on the back, can increase advocate exposure or back time of exposure;

② manuscript design was exceeded soft imprinted emersion capacity limits, improve manuscript design, make suit soft imprint technical limits.

7, the shift after plate making of on-the-spot, character and reason of breakdown of burst of the generation when bending and processing technique:

① advocate exposure and back time of exposure is too long, can decrease advocate exposure and back time of exposure;

② is divided stick time to grow too, decrease except stick time;

③ advocate exposure and back underexposure, whether examination tube damages or ageing.
