What should converters do to determine if dyne levels are acceptable before printing?
Different inks require different acceptable dyne levels for different types of substrates. A very “general” rule of thumb is that the substrate should be no less than 10 Dyne higher in surface energy than that of the surface tension of the ink or adhesive. Certainly also printing personnel should pre-check the dyne levels of the substrate via dyne solution. Application is with a single soft cotton tip applicator (Q-Tip), used only once. Dyne pens are not reliable as they could become contaminated.
