Anti Offset Spray Powder — TRIPC-ASF-POWDER

The TRIPC-ASF-POWDER is an anti offset spray powder from TriWill Group, formulated to prevent ink set-off in the delivery of sheetfed offset presses. Applied as a fine powder to freshly printed sheets, it creates a micro-separation between stacked sheets that prevents wet ink from transferring onto the sheet above during drying.

TriWill Group supplies TRIPC-ASF-POWDER to US sheetfed offset printers who need reliable set-off prevention with consistent particle size and low dusting for a cleaner pressroom environment.

Key Features

• Prevents Set-Off: Creates micro-separation to stop wet ink transferring between sheets.
• Consistent Particle Size: Uniform powder for reliable, even application.
• Low Dusting: Minimises airborne powder for a cleaner pressroom.
• Compatible Coverage: Works across a range of stock weights and ink coverage levels.
• Finishing Friendly: Formulated to minimise issues in downstream finishing.

Frequently Asked Questions

What is anti offset spray powder?

Anti offset spray powder (anti set-off powder) is a fine powder applied to freshly printed sheets in the delivery of a sheetfed offset press. It creates a micro-separation between stacked sheets, preventing wet ink from setting off (transferring) onto the sheet above during drying.

Why is spray powder needed in offset printing?

Freshly printed offset ink remains wet as sheets stack in the delivery. Without spray powder, the wet ink would transfer onto the back of the sheet above. Spray powder creates a microscopic gap that prevents this set-off.

Does spray powder cause problems in finishing?

Excessive or wrong-grade spray powder can cause issues in coating, laminating, and gluing. TRIPC-ASF-POWDER is formulated for consistent, controlled application to minimise downstream finishing issues. TriWill provides guidance on correct powder selection.

What particle sizes are available?

Spray powder is available in different particle sizes for different stock weights and applications. Contact TriWill Group for guidance on the correct TRIPC-ASF-POWDER grade for your substrates.
