Cleaning Vinyl Graphics

17-Oct-2012

Sign makers should assume that many of their customers will do some pretty stupid things when cleaning graphics. For this reason they must provide the end user with instruction covering proper cleaning and care of any graphics. When I sold fleet graphics, many years ago, I would give my customers an instruction sheet which included the do's and don'ts listed below: Read more

Mottling and what to do about it

17-Oct-2012

Have you ever occasionally noticed a dull, hazy or blotchy appearance on the surface of some vinyl films or overlaminates? This is a condition called mottling. There’s no reason to get too excited. While this hazy appearance certainly detracts from the aesthetic appeal of your graphics, mottling can easily be remedied, which I will explain all in due time. Read more

Painting Polycarbonate Sheet

17-Oct-2012

The extraordinary clarity of polycarbonate makes it an excellent substrate for backlit signs. Generally, but not always, the sheet is sprayed on its second surface. Because the paint faces the inside of the sign cabinet, it is protected from the elements. Any painting done on the first surface of the sign face must be clear coated. Read more

Screen Printing on Polycarbonate

17-Oct-2012

Painting is not the only solution for decorating plastic signfaces. For high-volume jobs, screen printing is an economical solution. In selecting an ink system, ask your screen print supply distributor for a recommendation. The technical bulletin will give you printing recommendations. The type of mesh, squeegee, stencil and thinners are a few of the variables that will determine the amount of ink deposited on the sheet, which affect the appearance of the sign, when it is illuminated.

Using Paint Mask with Etching Creams

17-Oct-2012

Chemically etching glass with etching creams is a quick, easy and safe way to produce a matte finish texture on glass similar to that of sandblasted glass. Note that I said “similar to” and not “the same as”. Chemical etching creams will not produce the same uniform, bright white finish that you achieve when sandblasting. Read more

Vinyl Application to Polycarbonate Sheet

17-Oct-2012

Even if polycarbonate sheet was covered with a surface protection film, you should always consider the surface contaminated. That means that you must clean the sign face before applying the graphics. Before you prep the substrate with a solvent or detergent, carefully read the manufacturer’s instructions. For most plastic-sheet applications, the most reliable cleaning method is a non-abrasive detergent and water. Solvents subject any type of plastic sheets to chemical stress, which can cause cracking.

What Causes Ink Adhesion Problems?

17-Oct-2012


The $64 question is: what causes ink adhesion problems when screen printing polycarbonate film? While some have suggested moisture absorption as the culprit, the most likely candidate is exposure to UV light and oxygen. As the polycarbonate absorbs UV light, it excites the photons of the atoms, which in turn creates free radicals. Free radicals are atoms with a few extra electrons. These extra electrons make free radicals highly reactive, or what I like to think of as being chemically promiscuous. These free radicals chemically react with any impurities in the polycarbonate film, such as sodium. The result of this reaction is degradation of the polycarbonate. This is why the film can yellow and become brittle. Read more

Drywall Preparation, Priming and Painting


In my story, Preventing Wall Graphics Failures, I mentioned that new drywall must be primed and painted properly to ensure good adhesion of pressure-sensitive vinyl wall graphics. You wouldn’t think that applying vinyl wall graphics to newly painted drywall should be a problem. Of course, problems can and do happen. Especially when contractors rush to get the job done.
