The purpose of the unit is to transfer UV coating to the sheet in a continuous fashion, either off-line or
in-line with your current production processes.
Note: Printed material must be 100% dry before sending through the UV coater
Sheets are hand-fed or Auto-fed into an input table, which sends the substrate through an
applicator and impression roller point that applies coating.
The coating is dispensed or pumped in automatically from a UV coating container.
A generous amount of coating stays between the two rollers when the metering roller
adjustment knobs apply pressure.
The sheets then exit the roller coater and are transported with a conveyor system to the IR and
UV lamps.
Production speed will be determined by a number of factors, including;
Sheet size
Sheet thickness (minimum thickness 100lb text)
Sheet Quality
Sheet Feeding
Coating Viscosity
Coating Temperature
Sheet Temperature
Dwell Time (Time the sheet spends on the conveyor after coating but prior to curing)
Lamp and IR Quality.
Required Gloss Level
Machine control settings
The importance of each of these factors cannot be overlooked.
Note: sheet stock thickness must be greater than 100lb text.
