Colorific Ultra 7000 contains a small amount of uv monomer, and is an optically clear, ultra fast drying, solvent-based primer specifically developed to enhance adhesion between UV curable digital inks onto the more difficult rigid materials such as PVC, Polystyrene and Polycarbonate. Since Colorific Ultra 7000 is fast drying, substrate can be printed within 5 minutes of application.
To Apply Colorific Ultra 7000
- Remove any protective film from the substrate.
- Remove any excess dirt with a dry cloth.
- Soak a lint-free cloth such as Clean Room Wipes with 7000 and wipe the entire substrate surface.
- Allow to dry – normally less than 5 minutes depending on the substrate size.
- Print onto surface.
- The viscosity of 7000 also makes it suitable for application by roller or pad.
- Apply 7000 evenly to the material and allow to dry.
- The chemical nature of 7000 is such that the primer can be applied up to 2 days prior to printing without any adverse effects on ink adhesion or outdoor weathering.
- Depending on the substrate and ink film deposit, the chemical bond might take up to 24 hours to complete.
- Materials primed with 7000 in this manner prior to printing will have greater water resistance for prolonged outdoor use.
- 7000 has a lower odour than 6800 or 7200 and can be used on other plastic materials.
Additional application advice for Primers: There are various application methods for Primers currently used by digital printers, lint-free cloth (eg Clean Room Wipes), Paint roller and Paint pad.
Pour the Primer into a shallow tray. Immerse or soak the cloth/roller/pad in the Primer and remove any excess. Alternatively, pour the Primer directly onto the substrate and wipe over the surface. Apply directly to the substrate, using one of the methods above, to give an even, smooth coating. When applying the primer it is important to avoid over-wiping, as this will result in poor flow and inconsistent thickness and will be visible on transparent substrates. Use a sweeping motion and avoid excessive overlaps and streaking. Take care that over-use of the Primer does not excessively damage the paint pad or roller.
General Advice – UV Digital Inks: Always check the adhesion performance of UV onto the selected media before committing to a print run. To minimise edge chipping stand prints for 24 hours before finishing. When printing clear materials prime the whole surface to avoid any optical differences in clarity. Images containing large areas of block colour should always be printed at the minimum speed to give the best finish. Corona treated materials such as ‘Correx’ degrade over time, so wherever possible use fresh stock. For backlit signage where possible leave a 3mm clear border around the image area.
