Exposure(plate burning)


Plate burning light: Iodine home light as the most suitable light source: due to the different light sources, plate exposure time will be different, the exposure recommended in the table is only a range;When using the same version, the exposure time is 20% longer than the normal exposure time, it is recommended to update the tube.


film:In order to ensure the quality of printing, it is recommended to print the film density of 3.5 or more


exposure time:STOUFFER21 gray-scale scale (grade.015) or UGRA PCW82 control strip placed on edge of plate, under film, properly exposed and developed under recommended conditions.The gray scale of the third level of exposure is the best exposure of the positive version, the ninth level of exposure is the negative version of the exposure;Or when the 10 -- 15 m microlines on the control strip are uninterruptible the positive line shall prevail and the negative line shall prevail.
