Sign Builder Illustrated contributor Jim Hingst writes: “In past articles, I cautioned that you should limit ink densities to no greater than 250 percent to 275 percent. One reason is that the volume of ink that you print on a substrate has a direct effect on the dimensional stability of the film that you are printing on. The more ink that you lay down, the more contraction of the vinyl you can expect as the ink dries. When this happens, the applied graphic can peel at the edges. Even before the film is applied, the vinyl can start to curl at its edges on the release liner.
“Failure to limit ink density can also lead to other problems, which I will expound upon shortly.”
