4300 series UV screen ink is designed for high speed printing of plastic containers. 4300 series inks exhibit excellent adhesion, as well as superior resistance to water, solvents, chemicals and other products typically packaged in plastic containers.
- Core substrates: HDPE: treated high density polyethylene, LDPE: treated low density polyethylene, PP: treated polypropylene, Additional substrates - PET, PVC: vinyl, styrene, PC: polycarbonate
- Use direct emulsions and capillary films which are solvent resistant and UV compatible.
- 4300 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
