Metal Forming Bead Rollers

Choose the right aluminum guide roller

1. According to the number of mesh lines of the aluminum guide roller, in order to ensure accurate reproduction of the dots of each tone level of the printing plate, each dot on the aluminum guide roller must be accurately inked. For this reason, the opening area of the aluminum guide roller should be smaller than the area of the dot, so that one or several ink holes can be inked, so that the dot is not trapped in the mesh, and the printed dot is enlarged.

2, high-precision aluminum roller according to the structure of the text, for the same high-precision aluminum roller mesh engraving process, the higher the number of mesh lines, the less the amount of ink, suitable for printing dots and small text; high-precision aluminum roller and cable The lower the number, the more the amount of ink is transferred, which is more suitable for printing large-area color blocks and bold characters.

3. Select the reticulated aluminum guide roller according to the degree of wear of the different aluminum rolls: when the volume of the inking hole of the anilox roll is reduced by half, it should be replaced with a new one.

4. The aluminum roller is selected according to the substrate. When the surface of the substrate is rough and the amount of ink transferred is large, the aluminum roller is required to use an anilox roller with a small number of screen lines; on the contrary, the substrate with a smooth printing surface needs to use a large number of screen wires. Anilox roller with a small amount of ink transfer.

5. Select aluminum guide according to different inking units.
