Graphic Applications
PALIGHT performs superbly in a wide range of graphic applications including those involving paints, screen printing, digital flatbed
printing and vinyl films. PALIGHT can be used to create weather-resistant signs, displays or Point of Purchase (POP) materials. The
smooth PALIGHT surface is ideal for all types of graphics, and it requires little surface preparation or surface treatment.
General Considerations
To ensure best results for any graphic application using PALIGHT, consider the following factors that may affect the finish installation:
 Environmental and safety concerns
 Weathering
 Chemical resistance
 Ease of application
 Cost-effectiveness
 Hardness
 Scratch resistance
 Priming or multi-coat paint applications
TIP: Because of the wide range of products available, select paints carefully for each application. Initial testing of the selected
paint system is recommended before a production run.
Cleaning / Pretreating
Before screen printing or painting PALIGHT, the surface area should be cleaned with isopropyl alcohol and a clean white cloth.
Depending on the specific application, certain pre-treatments may also be required, as described in the following sections.
Screen Printing
With PALIGHT, the process of Screen Printing is easily accomplished. The surface of PALIGHT has a closed cell matte finish that makes
mistakes easily wipe off with the appropriate thinner.The use of Vinyl and Vinyl/acrylic, solvent based inks are very compatible with
PALIGHT.
The use of Water Based Screen Printing Inks has also had some success with PALIGHT material. Ink manufacturer directions must be
followed for good adhesion. Surface preparation of PALIGHT for screen printing is similar to those of painting.
A. The surface to be screen printed area must remain dry, clean, and grease free.
B. Any surface scratches on the PALIGHT will have a tendency to shadow through the ink.
In order to remove small scratches or dents, rapidly fan a heat gun over the affected area. Care must be taken not to leave the hot air
in one place for too long, as the surface can become deformed. It is highly recommended that the surface be cleaned with a white
cloth moistened with isopropyl alcohol prior to printing.
All screen printing inks should be tested in a manner which duplicates your printing process before initiating production. It is strongly
recommended to consult the appropriate ink manufacturer regarding any required ink additives such as catalyst for proper adhesion
and exterior usage. Screen Printing ink should air dry, rather than be heat dried. Temperatures in excess of 150° F may cause warping
or bowing of PALIGHT material.
Most UV Screen Printing Inks that are compatible with rigid PVC will work on PALIGHT. The most important factor to be considered
when using UV systems is the curing oven. Low wattage bulbs should be used to keep the temperature below 150° F. The use of UV
curing systems, which have variable speed conveyors, are considered the best type to use with PALIGHT.
Direct Digital Printing
Wide format and flatbed printers use various ink and ink curing technologies to allow high quality printing at relatively high speeds.
High quality digital printing depends on various factors:
Printer capabilities •
Ink technology and quality •
Type of printing substrate and quality •
Machine operator •
PALIGHT’S bright whiteness enables printers to print directly on it and achieve accurate, consistent color values and brightness.
The PALIGHT is Suitable for use with UV curing and solvent-based digital inks, and for IR drying when water-based inks are used.
PALIGHT retains superb whiteness, even after intense UV curing.
