Sign Panel FAQs

Where do I purchase your panels?

Laminators sells through a network of distributors across the United States and Canada. Call 800-523-2347 to learn where to purchase our sign panel products today.

How do I prep your panels for digital printing?

Before starting, refer to the Owner's Manual for the specific printer, as well as recommendations from the ink manufacturer, for any instructions pertaining to the proper preparation of panels prior to print. While all of Laminators panels are digital print ready, they must be cleaned prior to use. Remove the masking from the panel. To prep panels, use a new color-free and lint-free cloth and spray 99% isopropyl alcohol on the wipe. Clean the panel in one direction (not in a circular motion), making sure to remove all visible oils, residue, and dirt. Please refer to Cleaning Panel section of our Sign Panel Production Guide for more information.

How do I prep your panels for painting?

Remove the masking from the panel. Refer to preparation recommendations from the paint manufacturer. To prep aluminum-faced panels, lightly scuff the face using 400-grit sandpaper. For vinyl-faced panels, use 220-grit paper. Wipe panels in one (non-circular) direction with a new color-free and lint-free cloth sprayed with 99% isopropyl alcohol to remove all visible oils, residue, and dirt. Please refer to Applying Paint section of our Sign Panel Production Guide for more information.

How do I paint/print on your aluminum-surfaced panels?

Laminators' aluminum-surfaced panel are comprised of a high-gloss, factory-baked, polyester paint finish. Please use paints recommended for painting on this type of surface. Refer to our Sign Panel Production Guide for painting recommendations. Our panel surfaces are ideal for digital inks (aqueous, latex, UV and solvent cured), screen print inks, automotive acrylic enamels, polyurethanes, and lacquers (some may require light scuffing with fine grit sandpaper prior to painting). Follow paint manufacturer's recommendations for proper application, thinning, and cure times. The panel surface must remain dry, clean, and grease-free prior to painting. Please consult with your local distributor to find the best inks and paints to use with our aluminum-surfaced panels.

We recommend performing a small paint adhesion test prior to painting. A cross-hatch test is a method for testing paint adhesion. Below is an explanation on how to perform the test.

How do I paint on your vinyl-surfaced panels?

Laminators' vinyl-surfaced panel products are also high gloss. Please use paints recommended for painting on this type of surface. Refer to the Sign Panel Production Guide for general painting recommendations, but consult with your local distributor to find the best inks and paints to use with our vinyl-surfaced panels. Our surfaces are ideal for automotive acrylic enamels, polyurethanes, lacquers, Krylon spray paints, and vinyl inks. The surface must remain dry, clean, and grease-free prior to painting. Follow paint manufacturer's recommendations for proper application, thinning, and cure times.

We recommend performing a small paint adhesion test prior to painting. A cross-hatch test is a method for testing paint adhesion. Below is an explanation on how to perform the test.

How do I perform the cross-hatch test (paint adhesion test)?

All you need is a good grade of masking tape and a sharp utility (or Exacto) knife. You begin by making eleven parallel cuts 1/4" apart vertically and horizontally, about 1" long with the utility knife over the cured paint. The end result should look similar to a "Tic-Tac-Toe" game pattern. Apply the masking tape over the scored area and press firmly. Immediately remove the tape by pulling it back upon itself at 180° in one rapid motion. Then inspect the cross hatch to see if any of the finish has pulled away with the tape from the cut area or if it is intact. There should be no removal of the paint squares.

How do I edge seal Laminators Sign Panels?

Please refer to the "Edge Cap" section of our Sign Panel Production Guide for recommended edge seal instructions. While there are many other "industry-accepted" edge sealing methods that may provide adequate results, we cannot recommend each alternate edge-sealing method used in the industry.

How do I cut Laminators Sign Panels?

Please refer to our Sign Panel Production Guide for recommended cutting instructions and techniques.

How do I clean Laminators Sign Panels

If cleaning to prep for printing or painting, wipe the surface in one direction (not in a circular motion) with a new color-free and lint-free cloth sprayed with 99% isopropyl alcohol to remove all visible oils, residue, and dirt.

If cleaning after sign installation, panels should be washed periodically to keep them bright and dirt free. Wipe panels with a color-free and lint-free cloth damp with solvents such as alcohol, mineral spirits, naphta and xylene.

Wipe again with a clean cloth or tack cloth and your surface is ready.

Does Laminators have recommended sign applications and installation techniques?

Please refer to our Sign Panel Production Guide for recommended panel applications and installation techniques. The recommendations within the Resource Guide are general industry accepted techniques. Please consult the local township where your sign will be installed for proper codes and ordinances required to properly install the sign.
