Printability Aids / Inkjet Fixing Agents
Printability Aids
Printability aids provide water resistance, ink receptivity and improved printability to coated paper.
These aids are used in coating color of coated paper and paperboard.
PRINTABILITY AID PA Series
- Provide printability to coated paper.
- Make “Dot” which configure the printed image clear.
- Enhance the water resistance and air permeability of coated paper.

Inkjet Fixing Agents
Inkjet fixing agents are used to increase the water resistance of inkjet printing paper and keep the ink from bleeding when the sheets are still wet.
The aids are used in paper for digital inkjet printing.
INKJET FIXING AGENT DK Series
- Improve water resistance of printed inkjet images.
- High quality images with no bleeding or beading.
- Enhance the print density and improve ink-set.
