Features of 6 Colors Sticker Label Flexographic Printing Machine

Use:

It is suitable for printing paper, paper board, high-grade self-adhesive label and so on.

Characteristic:

The quality of flexographic printing is closely related to the adjustment pressure of operation. The size of the printing press should be adjusted to the expansion of the dot, the edge effect and the hard mouth can not be seen or not obvious, which is essential.
When adjusting pressure, pressure should be zero and pressure should be consistent on both sides. (to make a version, put pressure line and test bar on both sides of the plate to ensure the pressure on both sides of the plate is consistent). In actual printing, depending on the layout, such as printing fine line version of the pressure should be relatively small, while printing the field version, the pressure should be relatively large. In addition, the adjustment of pressure includes the adjustment of contact pressure between the surface of the roller and the surface of the plate. When the pressure between the two is too great, the water-based ink will be squeezed from the surface of the plate to the four sides of the text, piling on the shoulder, at this time, even if the printing pressure is appropriate, the printing products will inevitably have a dot - dot phenomenon; Conversely, if the pressure between the two is too small, the transfer of the ink is affected. Be sure to use the "gauge" before using a set of rollers.  Under the condition of ensuring printing and pressure, between the plate and the anilox roll (plate thickness + double-sided adhesive thickness + substrates thickness - 0.01 mm), between the plate and substrates (plate thickness + double-sided adhesive thickness + substrates thickness - 0.01 mm), determine the above two pressure. In printing, the pressure of printing should be avoided, and the shadow on the edge can not be identified by the naked eye.

In the case of no measurement rules, the paper substrate sandwiched between the plate and the imprinting roller, and then gently pull, can be pulled out in a little harder after the situation. The pressure adjustment can also be displayed by the bilateral pressure gauge data, and the knob is adjusted. This can effectively protect the printing plate. Therefore, the printing plate is highly resistant to printing.

Printing pressure is also related to the printing speed, the printing speed is high, the printing plate and the bearing contact time is short, we should increase the printing pressure appropriately,otherwise, we should reduce the printing pressure. The pressure of the roller and plate roller is constant (0.02-0.03). The pressure of the printing roller is different with the performance of the substrate and can be adjusted.

In fact, the net roller and the printing roller, the printing plate and the printing roller, the scraper and the roller have formed a pressure zone, which can control the quality of the printed material.

The set accuracy, printing pressure control and the distribution of the roller and printing plate are the three problems of flexographic printing.

The precision of the set relates to the tension regulation and the quality of the plate. The printing pressure control relates to the node change and the ink color density; The combination of the roller and the printing plate is related to the quality of printing, which also affects the cost of investment and the management later.
