Painting is not the only solution for decorating plastic signfaces. For high-volume jobs, screen printing with either solvent or UV curable inks is an economical solution. In selecting an ink system, ask your screen print supply distributor for a recommendation. The ink manufacturers’ technical bulletins will give you printing specifications. 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.
