Whether to use imported or domestically produced printing equipment, the unstable performance of paper before printing is a major headache for many printing factories, especially for gold silver composite cardboard or transfer gold silver laser cardboard. The main problem is that due to temperature and humidity changes, it has already stretched and deformed before printing, resulting in lotus leaf edges; The surface coating varnish does not match the resin system of the printing ink, resulting in mutual solubility; Serious surface abrasions, etc.

The printing width of the gravure printing production line is 400-820mm, and it can print from 80g/m2 single-sided copperplate paper to 350g/m2 cardboard. The printing speed can reach up to 300m/min. From white card paper unwinding, transfer and composite film unwinding, adhesive bonding, oven drying, peeling, cooling, OPP and PET film winding, surface coating with varnish, to line printing (front and back laser positioning printing), UV sanding, UV oiling, and cutting into large sheets, it can be completed. Glue coating and independent driving of 9 printing units.

Gravure UV equipmentThe tasks that can be completed include: (1) transfer, peeling, printing (front and back printing, front laser positioning printing), UV sanding, UV oiling, and cutting large sheets. (2) Stripping, printing (front and back printing, front laser positioning printing), UV sanding, UV oil coating, and cutting into large sheets. (3) Complete composite printing (front and back printing), UV sanding, UV oil coating, and cutting into large sheets. (4) Complete single-sided copperplate paper, white cardboard or gold and silver cardboard printing (front and back printing), UV sanding, UV oil coating, and cutting into large sheets. (5) Milk carton printing, oiling, and cutting into large sheets are completed. (6) Partial transfer of milk cartons (equivalent to cold ironing or holographic anti-counterfeiting positioning hot stamping), printing, oiling, and cutting into large sheets are completed. (7) The paper guide roller is made of special metal and has undergone special surface treatment, which can print plastic packaging. (8) Provide transfer paper and composite paper processing for single sheet printing (offset printing, gravure printing, etc.).

The adoption of this production line also solves a major problem in the pre press processing technology, and eliminates the need to purchase metal paper from the packaging paper composite factory, saving some tedious processes, effectively saving time, and reducing production costs.
