Gravure Common Faults - Poor Print Reproducibility

Cause: The printing plate is too dark and contains too much ink.

Countermeasures: 1 increase the number of mesh lines; 2 reduce the ink color; 3 appropriately increase the angle of the squeegee and the surface of the printing plate.

2. High light is too shallow.

Cause: The depth of the plate is not enough.

Countermeasures: 1 Use dark-toned ink; 2 properly reduce the angle between the squeegee and the plate surface. (3) Dark tone (dark part) is too deep.

Cause: The plate is too deep.

Countermeasures: Due to the lack of ink drying, the ink layer may be agglomeration, and if necessary, it must be reprinted.

3. Dark tone density is not enough.

Cause: The plate is not deep enough.

Countermeasure: Use dark color ink.

4. The depth of the intermediate tone ink junction is obvious.

Cause: Poor ink.

Countermeasure: Replace ink with good characteristics.
