Detailed introduction of UV gloss coating process
For practitioners who are engaged in UV printing and glazing soon, composite technology is a perfect starting point. This technology is characterized by very good process stability. The configuration of the compound printing machine is the same as the basic model of the UV equipment, and it can be alternately produced within the specified parameters.
Printing and configuration:
Rapida 106-5 + glazing unit, two-page extended paper collection device.
Printing unit 1-5: conventional ink roller
KBA Rapida 106
KBA VariDry drying device technology:
-2 drying units between UV units, each equipped with a 200 W / cm lamp tube-each printing unit is equipped with a joint fitting for the drying unit between units-an extended paper delivery device equipped with infrared and hot air drying devices -3 varnishing units with anilox rollers placed in the last 200 watts / cm of UV drying device on each varnishing unit, alternately used for UV / water-based varnishing anilox roller cross-hatching, 100 lines / cm, absorption The volume is 12 cubic centimeters per square meter
UV gloss glazing samples
Production technology:
The first printing unit: Pantone Cool Grey 9 Hybrid
2nd-5th printing unit: Composite overprinting primary color unit Drying device: working in the 2nd and 5th printing units Glazing unit: UV high gloss glazing oil, full-length glazing lengthened paper collection device: infrared and hot air The drying device is turned off and placed in the last UV drying device
The Pantone Cool Grey 9 Hybrid (Pantone Cool Grey 9 Hybrid Ink) was used in the first printing unit, and the composite overprint elements were in the second to fifth units. These inks are cured by the inter-unit drying device that operates behind the second and fifth printing units, and then the printed sheets are UV-coated in full width, and are fully placed by the final UV drying device in the take-up device. dry.
