3800 series poly banner ink has been formulated specifically for indoor and outdoor treated polyethylene banner applications, where excellent adhesion and superior flexibility are required. Properly cured, this ink will resist blocking when stacked ink to ink.
- Substrate surface treated polyethylene banner film (45 dynes per cm or higher)
- Use direct emulsions and capillary films which are solvent resistant and UV compatible
- 3800 Series is formulated to be press ready
- Thoroughly mix the ink prior to printing
- Improper mixing can lead to inconsistent color and ink performance
- Lower temperatures increase the ink viscosity, impairing flow and increasing film thickness
- Elevated temperatures lower the ink viscosity, reducing print definition and film thickness
- Pretest to determine optimum printing parameters for a particular set of ink, substrate, screen, press, and curing variables/conditions
- The ink can be affected by stray UV light
- Be aware of skylights, windows and overhead lights curing the ink in the screen; light filters are recommended
- Leaving a container uncovered may result in the ink’s surface forming a "skin", caused by reaction with ambient lighting
- Keep containers covered
