The face paper and corrugated cardboard laminated, like this laminated cardboard, from the face paper to look at a fixed position with obvious offset (color darker than normal face paper color and will not dry), although this is caused by the glue, but most of the reasons related to machine adjustment.

Possible causes of offset printing:

1.If it is really a glue problem, then the glue is too thick on the amount of glue is too large, appropriate thin point on the amount of glue smaller even point can be.
2, check the rubber roller may leak glue

4. The garbage on the corrugated paper is stuck to the glue rollers. The glue rollers have a slanting cover, and the garbage is pressed on the top side, causing the

There is another kin glue to be too large for the face paper.
d of cardboard and cardboard framing, i.e., flat paste flat, the main problem is the glue: glue is too thick on the glue is too big to dump glue, appropriate to reduce the concentration of glue to reduce the amount of glue, glue tuned evenly.
