3D letters and/or 3D logos are made of plastic, metal or foam. They reinforce an upscale image and create a clear highlighted message. These signs can be illuminated when required.
Most of Palram's products that are delivered with PE film covering are suitable for thermoforming. In general, we recommend using clear PE and not printed PE.
For use in illuminated signage, PALSUN, PALSUN CS (Coil Stock) and PALGLAS are suitable for the sign face; and PALBOARD, PALOPAQUE, and PALIGHT for the body of the letters or symbols. For print & display, Palram's entire product portfolio can be used based on the specific application. This choice depends on a combination of several parameters, including the cost of the media, its durability, and its suitability for the specific application. Please visit Palram’s Flat sheet application catalog for more information.
Sign faces are usually made from polycarbonate or acrylic. For extreme conditions such as heavy hail, low temperatures, or high temperatures produced when thermo-forming, polycarbonate is probably more suitable. For sign boxes or channel letter cans, PVC, multi-layered PVC and foam PVC can be used.
A sign that is illuminated by an electrical light source (fluorescent\LED).
Before: use a protected sheet with PE masking, store unused inkjet printable media in original packaging and in a clean area, and avoid touching the print side by handling the edges of the sheet or by using lint-free white gloves.
After: avoid any finishing until prints are completely dry, store the printed media in a clean environment, and avoid dust from sticking to the fresh cured ink.
In terms of ink adhesion properties, both polymers act very differently. PVC is a ready-to-use polymer so no pre-treatment needs to be done before printing (on rigid or flexible media). Polypropylene has different chemical properties and for this reason, needs to get a pre-treatment coat ('Corona'), which has a limited shelf life.
This is based on a combination of several parameters, but the main ones are the cost of the media and its durability, and its fit to the required application. Please visit Palram’s Flat Sheet Application Catalog.
A strict spec of diagonal (from angle to angle) during the production process is feasible for this.
