Colorific Ultra 7000

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, substrates can be printed within 5 minutes of application. Colorific Ultra 7000 is supplied in 1ltr containers.

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
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.
