The Ink Proofer is highly useful for ink manufacturers and printers as an essential quality control tool.
The 200 x 50 mm prints are useful for colour checking. As well as measurement of density, penetration, set-off and drying. They may also be useful in conjunction with IDM’s Ink Rub Testers for rub and abrasion testing.
The ink proofer comprises of an Inking device and a Printer unit. These are also available as separate items.
The Inking Unit:
It is a three roller design, consisting of one aluminium drive roller, one aluminium reciprocating roller, and a rubber distribution roller. This roller combination provides quick and uniform distribution of the ink. An arm holds the Print disc in contact with the rubber distribution roller. Thus, giving an even transfer of this ink to the Print disc.
Place the inked up print disc from the Inker unit to an arm above a motor driven impression roller on the Printer unit. Then place the substrate to be printed between the impression roller and the print disc on the printing ledge. Apply a printing pressure of up to 1000 N to the Print disc by means of a sliding weight on a graduated bar. Pressing and releasing the print switch provides one revolution of the Print disc.
