Not all spray powders are the same; the uniformity of the particle size with KSL spray powders allows up 33% less powder to be used when compared to other regular brands.
An essential property of any anti set-off spray powder is the structure and conformity of particle size. These illustrations show the function of the anti set-off powder working as spacers between the freshly printed sheets. The difference achieved by a uniform spray is clearly illustrated above. The application of equal grains at a regular distance ensures minimum consumption, even stacks and trouble free printing.
Water based coating
When printed sheets are to be coated with water based emulsions it is recommended to use a spray powder that is hydrophobic, that means water repellent. Our S5 WL spray powder is water repellent and also due to its regular particle size enables a reliable spacer between the sheets enabling sufficient air in the stack, which is required to support oxidative drying of the ink beneath the coating.
