Precision Type High Roller Gauge – for Letterpress Platens
The Lyme Bay Press Precision Roller Gauge allows letterpress printers to accurately set the height of the inking rollers on a platen press. Remove the chase and ink up the press then place the roller gauge flat against the rear casting where the chase would normally sit. This allows for a near perfect print first time when using a combination of The Chase Base and our polymer printing plates for letterpress.
Carefully turn the flywheel of the press until the ink rollers pass gently over the round disc of the gauge ensuring the gauge remains still and flat. Wind the rollers back down and remove the gauge and examine it.
A thin stripe of ink will have appeared, this stripe should not be more than approx 2.5mm if it is the rollers need raising by adding packing to the inking rails, a length of tape may suffice. Repeat the test and keep adding packing until the stripe is the correct thickness. The tolerance for ink is very tight, the better this procedure is performed the better your inking will be!
