Our line of coated anti set-off powders perform exceptionally well in electronic units and air guns and can be over-printed, over-varnished and do not affect the printing plate or associated machinery. Our powders are safe for use in food packaging.

Packaging: 1 Kilo/bag - 10 Kilo/box.
Our 1 kilo bag is supplied with a re-sealable spout making it easy to pour the powder and ensuring moisture proof storage thereby reducing waste.

The powder forms a separation between the sheets thereby trapping air which reduces ink drying time. An even distribution of powder eliminates the suction effect between the printed sheets and also provides excellent protection of the printed image. Coated powders are primarily used by large corrugated printers, carton manufacturers and larger multi-color sheet-fed printers. As the weight of the substrate or height of the stack increases, the micron size of the powder should increase as well.

Correct use of powders entails that nozzles and pipes are clean and that there is an even spray pattern across the sheet. Use a minimum quantity of powder to prevent set-off. Less is often better as most problems with anti set-off powders are due to over-spraying. If a high amount of powder has to be used to prevent set-off it is likely that a smaller amount of a larger micron powder would perform better.
