The ink used in flexographic printing is a low viscosity ink similar to gravure printing. It is necessary to select inks of different binders and solvents for printing according to the quality requirements of the products. For example, in order to obtain a print having good heat resistance and toughness imprint, an ink made of an acrylic alcohol resin as a binder may be used; it is desirable that the print has a good gloss, and an ink having a polyurethane resin as a binder may be selected. For example, printing on polyethylene non-absorbent film, you can choose fast-drying, good adhesion ethanol solvent ink; if you print on corrugated board, book, newspaper paper, you can choose easy to clean, no environmental pollution Water-based inks, this article will introduce you to the flexo press roll manufacturer.
The flexo press machine personnel must carry out a comprehensive inspection of the equipment, repair, lubrication, commissioning, wiping, and wait until the workshop is inspected before it can start production next time. At the end of each month, concentrate the force on the equipment for thorough maintenance.
From the material and process of the flexo press, whether the machine structure is a uniform material, whether the main parts are made of special technology, our screen printing equipment is made of aluminum, aluminum and other aluminum materials, no one is used. The iron is easy to rust, the whole body is sprayed and sprayed, and a protective film is added to the whole body.
With the continuous development of printing technology, the flexographic printing line has no longer adhered to a single printing method, and has begun to transform into a diversified processing method that combines various printing processes and post-press processing. There are many successful cases in which a variety of processing methods such as gravure printing, screen printing, cold stamping, embossing, die cutting, etc. are added to a flexo printing machine.
The key here is that the flexibility of the printing plate is fully utilized: although the bulk is very gentle on the ground, but the kiss is full, the printed ink is very good, and there is no hard mouth; and the small text, thin lines, screened image part The printing plate has a high hardness, and the dot is not easy to expand and deform.
