【PVC Card - Business card printing】The following is causing business card printing precision error of several common reasons: 1. in making the polychromatic overprinter (half-tone business card printing) of the screen, the screen is on a different temperature drying, hence making precision errors. 2. the network version of the tensility overprinter (or multitoning) screen tension. 3. use for infra-red mask simply drying, dry. 4. using is too old and weak, and the deformation of the screen frame seihan, because of the screen frame volatility resulting business card printing image deviations (these problems can be detected with film). 5. multicolor printing is used, the use of the network distance is inconsistent. 6. the squeegee deformation. 7. subject to certain factors causing substrate size change.
