Z-INKS AQUATINGS 227 is suitable for application via the ink ducts on all popular presses, including Heidelberg, Komori, KBA, and Rolands.

GENERAL TECHNICAL DETAILS

Z-INKS AQUATINGS 227 has been formulated for application via ink ducts and can be applied in-line over wet ink as well as off-line. The coating dries via a combination of penetration and evaporation and requires accelerated dryers in the form of hot air knives and IR lamps. Optimum stack temperatures are 28-32°C. A slight application of a medium to large sized spray powder is recommended.

Z-INKS AQUATINGS 227 can be applied as a dry solid using a rough grained aluminium plate or as a spot image by stripping a blanket or by employing a photo-polymer plate.

Upon starting up, it is recommended to apply a heavier than usual film weight. This will assist with any initial drying/stability problems. The film weight can be reduced as required. During press stops, the plate and blanket should be cleaned using either warm water or a dedicated wash. Upon starting up the rollers should be sprayed with a fresh start retarder in order to ensure a clean start up.

Z-INKS AQUATINGS 227 contains silicones that are unsuitable for gluing or foil blocking.

STORAGE AND HANDLING

Waterbased emulsions should not be exposed to temperatures below 5°C or above 35°C. During cold months, it is recommended that containers are kept off of cold oors and stored on pallets. All emulsions have a 12 month shelf life - if unopened and stored in the correct conditions. Manufacture date is available on the label. Waterbased emulsions are non-hazardous and require no special storage or labelling.
