The inks in the PAL Matte8 series are screen printing inks newly developed for polyester film (PET). All known drawbacks of the conventional inks for PET film were corrected and all industrial needs as well as the latest screen printing technology were carefully examined to develop the PAL Matte8 series.

Specifications
Ink type Air-drying ink blended with polyester resin.
Usage Powerful adhesion to polyester (PET) film.
Finish Matte satin finish.
Coverage Approximately 30m2 per kilogram using Tetron 250-mesh screen.
Drying time Sets to touch in about 7 minutes at room temperature allowing overprinting. Obtains about 90% of its physical properties after standing for 24 hours. Thermal curing at 60-80°C for 10-20 minutes is recommend ed to account for work environment and seasonal fluctuation.
Diluent Standard solvent (T-995), slow-dry solvent (T-997), retarder (T-980).
Wash-up T-903
Notes PAL transparent inks are available separately for transparent finish, good leveling, or for metallic colors.Slow-drying PAL type inks are also available for fine line printing and other applications requiring higher work efficiency.

The inks in the GAP New series are designed for printing on polyester film. They feature outstanding adhesion and workability.

Specifications
Ink type Air-drying ink blended with polyester resin.
Usage Polyester films in general.
Finish Semi-gloss finish of good leveling properties.
Clarity Opacity varies with the color. Eight transparent colors are also available.
Coverage Approximately 30m2 per kilogram using a 250-mesh screen.
Drying time Sets to touch after about 20 minutes of air-drying (at 20°C). May take longer in work environments filled with solvent vapors. Adhesion problems may result due to residual solvent if drying is insufficient. Thermal curing at 50-60°C for 5-10 minutes is ideal.
Adhesion Adhesion is good, but varies with the film surface quality. Test before use. Overprintability is also satisfactory.
Diluent Standard solvent (T-977), slow-dry solvent (T-980), retarder (T-953).
Wash-up T-903
Notes • Mediums include GAP NEW-800 medium, GAP NEW-800 matte medium, GAP NEW-850 halftone base medium, etc. • Addition (5-10%) of reinforcing agent D improves adhesion.
Test Conditions
Drying GAP NEW-710 print results measured after thermal curing at 80°C x 30 minutes or 1 week of air drying.
