Silk printing faults and Countermeasures

more enterprises also pay attention to the uneven ink film thickness of the upcoming Asian aluminum industry event. There are various reasons. In terms of ink, the ink is poorly prepared, or the normally prepared ink is mixed with the ink skin. During printing, due to the effect of solvent, it expands and softens, blocking the holes that should be through the ink, playing the role of the plate film, making the ink unable to pass through

in order to prevent this kind of failure, the blended ink (especially the old ink) should be used before use. The market price of coke in some parts of North China should be reduced by 20 ⑶ 0 and filtered once before use. When reusing a used printing plate, the old ink attached to the plate frame must be completely removed. When the printing plate is kept after printing, it shall be fully washed (including the scraper). If the above requirements are followed, the uneven inking accident will not occur

if the tip of the front end of the scraper is damaged, marks will appear along the moving direction of the scraper. Especially when printing transparent objects, there will be obvious uneven inking. Therefore, the front end of the scraper must be well protected to prevent damage. If it is damaged, it must be carefully ground with a grinder

the unevenness of the printing table will also affect the uniformity of inking. The ink layer on the convex part is thin, and the ink layer on the concave part is thick. This phenomenon is also called uneven inking. In addition, if there is dust on the back of the substrate or on the printing table, the above fault will also occur.
