A 50% reduction of IPA concentration of 10 t0 15 % (vol.) in dampening water still in common use today to 6 to 8 % (vol.) makes an important contribution to the reduction of IPA emissions into the air. The impact on emissions achieved by further reduction of the alcohol concentration to Emulsifying graphs by Surland
unlimited water pick-up leads to increase of dot gain, toning and unequally printed areas
very fast ink-water balance, therefore sharp dot and fast start-up of plates
poor water pick-up leads to bad ink transfer, decrease of ink density, to sharp dot gain and partly blinding of the plate
Â
Â
Isopropyl Alcohol
Â
Â
Â
Used in sheetfed / web fed printing industry:
Â
Used as a dampening additive in alcohol dampening unit and reduces surface tension
It increases fountain solution transport to inking plate and inking unit.
Increases viscocity of fountain solution.
Faster wetting of plate .
Less ink build up on dampening rollers.
Cooling effect in the press / chiller unit because of evaporation.
