Adhesive trademark bronzing failure and exclusion

Failure 1 hot stamping or hot stamping is not strong

Reason: The low hot stamping temperature, low printing plate pressure, crystallized or smooth surface of printing ink layer, too thick ink layer and improperly-designed anodized aluminum may cause this failure.

The solution to the problem is:

1, properly increase the stamping temperature;

2, increase the pressure on the plate;

3, change the ink composition, so that the ink layer table modification;

4, reduce the ink layer thickness, reduce overprinting;

5, change other types of aluminum.

Fault 2 Electro-aluminum reverse pull ink

Cause: The printing ink layer is not dry enough, the ink adhesion is too low and the electro-aluminum separation force is too large to cause this failure.

The solution is:

1. Before stamping anodized aluminum, allow the ink to dry thoroughly;

2, change the ink composition;

3. Switch to electro-aluminum with low separation force.

Fault 3 imprints nourishes hair

Cause: Improper pressure adjustment or plate temperature is too low

The solution to the problem is:

1, adjust the pressure, local pad version;

2, properly increase the temperature of bronzing.

Fault 4 Imprint Metal Gloss Reduction

Cause: The plate temperature is too high.

The solution to the problem is:

1, reduce the electric heating temperature;

2. Reduce unnecessary downtime and reduce downtime.

Fault 5 is unclear, lack of painting

Reasons: When it is not clear that this type of failure is encountered when printing, it is necessary to first consider whether there is a defect in the bronzing plate itself. In addition, the galvanized aluminum is too tight, the stamping pressure is not uniform, the galvanized aluminum is too narrow or the paper guide direction is offset, etc. The cause.

The solution to the problem is:

1, replace the printing plate;

2, reduce the tension of the aluminum;

3, local patch version, keep hot stamping 沽 σ 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢.

5, adjust the guide mechanism.

Failure 6 Adhesive labeling The most likely quality problems in foil bronzing - Thin film materials and UV ink surfaces are difficult to foil and imprinted
The solution to the problem is:

1. Select dedicated, matching bronzing foils and use imported materials as much as possible;

2. Protect the printing plate, require the printing plate to be smooth, and have no dirt on the surface;

3, film material should be corona treatment to increase its surface tension;

4, reduce the hot stamping area, to ensure the plate's smoothness and stamping pressure uniformity;

5, the use of hard liner material requires the liner to be flat and uniform;

6, through the test to find out the best combination of stamping pressure, speed, turbidity, waste discharge.
