Protecting elastomer properties, preventing         premature hardening Higher flashpoint for each application         guarantee ROLLER CARE PRODUCT FRIDAY A + FRIDAY B If you can see it, it is already too late – calcium carbonate deposits on the rollers, that is. The only thing which will remove them is an acid, and this operation seldom leaves the roller itself undamaged. Calcium carbonates are salts present in the paper, the colour (especially magenta, with its high pigment content) and the water used. They are deposited to gradually form a microscopically thin layer over the roller. Since they attract water, this constitutes an even more troublesome problem on colour rollers, and in extreme cases the deposits can even bring the entire printing procedure to a halt. FRIDAY ON MY MIND So act to prevent them. With its «friday» treatment, DruckChemie has an exclusive product in its range – one which provides a lasting, prophylactic effect. This package of measures for the prevention of damaging deposits consists of an activating agent which identifies the calcium carbonate and a flushing material which disperses it. These materials are applied once (always on a friday) after your colour rollers have been subjected to their normal cleaning procedure. The treatment lasts for four weeks and ensures that you can rely on consistent printing quality.       POROPAST Roller cleaning paste for fast, pore deep colour changes.
