||It is often necessary for the lithograph operator to intervene during printing or when the machine is at standstill in order to remove from scumming, blind spots, inking of non-image areas, and oxidation on presensitized plates. CLEANER 90 resolve these problems in the best possible way. This plate cleaner is a highly active deoxidizing cleaner-detergent studies for the rapid removal of oxidation and inking of non-image areas from every analogical plates. The formula of CLEANER 90 consists of a particular combination of hydrophile and lipophile components which, when passed over the plate with a viscose sponge, remove the ink, eliminate the oxidations which cause inking of non-image areas and, at the same time, activate the printing areas, preparing them for easy and rapid inking. CLEANER 90 restores ideal printing conditions. CLEANER 90 is totally free from V.O.C. (Volatile Organic Compounds). In case of extremely bad toning or dirt on the plate surface we recommend the application of POLISH 90 with small abrasive.
