Printing using the waterless process requires the printing press to be maintained to the highest of standards, in order that it can be operated to an expected quality and consistency, which is then translated onto the printed sheet. Today new rollers have been installed in the yellow unit, and the unit is in its final stages of re-calibration.
The ink film thickness on the duct roller has to be set at its minimum of 6 microns. This little gadget (in the image) reads the thickness to ensure that the ink applied to the new rollers is accurate.
It is imperative that this measurement is correct to ensure that the printed sheet matches to the Epson proofs quickly, as any variation which adds time and therefore loses efficiencies in the production process.
Other factors that may impact the thickness of the ink film may include air temperature. If the pressroom is cold the ink will become stiffer and less mobile. Air conditioning within the factory provides a consistent working environment, to eliminate these types of variations.
This is a very small part of the maintenance required to ensure that the manufacturing process limits any possible defects. This helps to provide the exceptional quality we work towards – every time.
