1) The printing ink is a low-viscosity, volatile and dry printing ink with alcohol and water as the main solvent. It has a fast drying speed and is suitable for high-speed and multi-color flexographic printing. The application of pollution-free, fast-drying water-based ink is extremely beneficial to environmental protection.

2) Flexo printing machine is a photosensitive rubber or resin type printing plate, which is soft, bendable and full of elasticity. The Shore hardness is generally 25~60, which has good transfer performance for printing inks, especially for alcohol solvent printing inks. This is incomparable with lead plates and plastic plates with a Shore hardness of 75 or higher.

3) Use light printing pressure for printing.

4) The printing materials for flexographic printing are very wide.

Why is the production efficiency of Flexo printing machine high?

The production efficiency of Flexo printing machine is very high. Flexo printing machine usually uses roll-type materials, which can be completed in one continuous operation from double-sided multi-color printing to glazing, laminating, bronzing, die cutting, waste discharge, winding or slitting. In lithographic offset printing, more personnel and multiple equipment are often used to complete the process with three or four procedures. Therefore, flexographic printing can greatly shorten the printing cycle, reduce costs, and enable users to occupy an advantage in a highly competitive market.

How to clean Flexo printing machine?

The Flexo printing machine can be cleaned by jetting with fine plastic beads, using fine plastic beads. This cleaning method can increase the cleaning speed of the anilox roller by 30%, and while improving the printing quality, it can also extend the service life of the anilox roller. This method consumes less plastic beads, and there is no discharge of harmful substances and precipitation of chemicals during the cleaning process, which is beneficial to environmental protection, high efficiency and safety.

Ink blocking ink holes is a headache in flexo printing. You can clearly observe the ink hole blocking with a 10x or 20x magnifying glass.

From the perspective of the printing process, the flexo ink volume is generally required to be 1.2 grams per square meter (less for UV ink). If a 60-degree ink cavity angle is used, when the screen number of the anilox roller is 300 lines/in, the ink cavity The volume is 3.5 cubic centimeters per square meter. Using such anilox rollers, the amount of ink that can be transferred by the ink pocket is up to 40%. The thickness of the ink layer in the graphic part of the printing plate is about 1.5 microns, which is the lowest dot expansion rate.
