some common reasons caused the printing accuracy error

Here are some common reasons caused the printing accuracy error:

1 in the production of multi colour printing (printing) of the screen, the screen in different temperature drying, resulting in the printing accuracy error.

2 screen tension is low or overprint (half tone screen tension).

3 the use of hair dryer drying, drying does not mean simply screen.

4 the use of too old, not knot and has a deformation of the screen frame plate, because the net frame not disorderly sex difference caused by printing image deviation (these problem can be used to detect the film).

5 multi-color overprinter, use the network not consistent.

6 squeegee deformation.

7 under the influence of certain factors lead to substrate size change.
