Lid Top Boxes Silk Lining For Jewelry Commercial CTP system output process

There are a number of considerations when it comes to CTP output, and I list them here.

1. The files to be output must be copied to the specified folder, which is mainly for the safety of electronic files on the network; At the same time, shall not be placed and deleted at will related to the file, which is convenient for later supplement version; File input, should be recorded, easy to query in the future; The operator shall have written handover registration for each input file, output plate and quantity; The checked plates should be placed neatly to avoid confusion and scratches; Each set of plates should be marked with name, number, etc.;

2, output plate, should first check the working state of the developer, to see if there is enough developer and supplement liquid. Developer temperature and development speed is correct, if can not meet the requirements, it should be adjusted in accordance with the regulations;

3, the plate before exposure should first check the layout has no defects, such as whether the layout has scratches and so on;

4, the operator should avoid contaminating the layout, while the plate should be handled lightly;

5. After CTP output, the plate quality test can be carried out with x-Rite measurement to ensure that the density of blank part should be less than 0.29; Plate film retention ratio (field density after development/field density before development) should be greater than 90%;

6, the plate linear has strict requirements of the printing plant, when the development of the Ic-Plate measurement, 50% of the dot correction dot percentage fluctuation of more than 3%, and can not be restored to the original standard by adjusting the development time and temperature, should replace the developer;

7. Quality requirements for the layout after development;

A. The page should not be scratched; B. No dirty spots can appear on the page; C. The layout should be fully developed and look clean; D. Whether the layout overprint line and corner line are complete. If there is any missing, take remedial measures in time; E. Check whether the bite is correct;

8. After the developer is turned off and then turned on for use, at least 5 pieces of waste version should be washed first, so that the developer can achieve the best working state and ensure the quality of development;

9, developer temperature control is very important, the temperature difference of ±0.5℃, the version of the dot will change, should be used to display temperature and digital thermometer measurement combined method, strict control, and do the four corners of the temperature of the developing groove consistent, error does not exceed ±0.5℃ is better;

10, if the developer is not used for a long time, the developer can be put back into the plastic bucket sealed storage, and then pumped into the developing tank to continue to use;

In addition to the above, in the process of CTP use, but also regular maintenance of CTP equipment, such as checking whether the filter element is clean, if a little dirty, it should be replaced in time; Regular cleaning of relevant components and so on.
