UV offset press for lenticular print :
Equipment must be adapted to print on media sensitive thermoplastics. With, for example, a feed table has a central vacuum cord. Venturi Technology ensures optimal guidance sheets between printing units. The press must not allow settings to 10µ (circumferential, lateral, through).
The steps between the printing units should allow the location of UV dryers drawers interchangeable.
The ink rollers, dampeners and blankets should be resistant to UV radiation and detergents. Washing and regular cleaning is necessary.
The temperature control ink is recommended. The higher viscosity and abrasion UV inks are raising the temperature of the ink in the inking device. In lenticular print, the ink / water balance is less stable than conventional inks. An air table ensures stability inking a consistent print quality throughout the run, reduces the evaporation of ink and smear machine.
The installation of agitators ink is highly recommended. They prevent the solidification of high viscosity inks.
UV inks that are used to lenticular print are highly abrasive, so the metering rolls must be designed to prevent abrasion and prevent deterioration of the plastic sheets that protect the ink.
Upon receipt, a delivery extension with sheet metal guide sheet "Venturi" water-cooled, stainless bars clips without shade and oversized front and a stained glass protection filter UV light reflected.
Heat, ozone and the smell of varnish and ink are removed without negative influence on transfer sheets.
