Analysis: several factors cause printing errors
the following error caused printing precision is common for several reasons:
1. making color printing (half-tone printing) when the screen, screen drying at different temperature, thus causing the printing precision errors.
2. network version of the low tension or overprint (halftone) different screen tension.
3. use hair dryer drying, Jane screen drying unevenly.
4. using too old, flimsy and deformation of the screen frame plate, printing images due to screen frame stability bias (these negatives can be used to detect).
5. multicolor printing is using do not match the network.
6. squeegee deformation.
7. affected by some factors causing changes in substrate size.
