1. The surface smoothness of the anilox roller:

If the surface smoothness of the anilox hole is poor, it will lead to a decrease in the ink transfer capacity of the anilox roller, affecting the quality of product use.

2. Coating amount control:

Uneven coating amount can affect the quality of thermal paper. Uneven coating amount may be caused by rough and uneven surface of the anilox roller, poor circulation of the coating solution with dead corners, uneven surface hardness of the aging rubber roller.

3. Wear of the anilox roller:

Uneven wear of the anilox roller can affect the coating effect, such as the wear of the anilox roller and the appearance of stripes on the surface.

We recommend using a blade knife coater, as its advantages mainly include the following:

1. Precise control of coating thickness:

It can achieve precise control of coating thickness.

2. Uniform coating results:

It can provide uniform coating results.

3. High solid content coating:

It does not require the coating to have the characteristics of softness and strong fluidity, and can perform high solid content coating to improve coating speed.

4. High coating speed:

It is suitable for high-speed coating, which is very beneficial for improving production efficiency.

5. Coating smoothness:

The surface coated by the blade knife coater is very smooth and does not fluctuate with the surface of the base paper, which is very helpful for improving the smoothness and glossiness of the paper.

6. High operability and adjustment accuracy:

The operability of the blade knife coater is higher than that of the air knife, and the adjustment accuracy is also higher.

7. Suitable for high viscosity and large coating amount:

The blade knife coater is suitable for high viscosity and large coating amount coating.
