Ink-Substrate Interactions...
August 1, 2009

Broadly speaking, there are two kinds of ink-substrate interactions: desirable and undesirable. Desirable ink-substrate interactions are defined by their outcome: satisfactory ink adhesion; appropriate scuff-, weather-, or moisture-resistance; light-fastness, color-fastness, printability, etc. Undesirable interactions fail on one or more counts.

To UV or Not to UV. . .
November 1, 2006

UV inks are commonly used in package-printing applications. So much so that Don Duncan, director of R&D, Wikoff Color Corp., thinks it’s about time to rephrase how we reference ink categories. In referring to water-based and solvent-based inks, he says, “I use the phrase ‘so-called conventional’ because UV inks are now so common that they are no longer ‘unconventional.’ We need a new word for the mixture of oil-based, water-based, or solvent-based inks that UV is replacing. How about ‘old-technology.’” The term “old technology” might not fly (Duncan admits that it’s “a little over-the-top”), but the point is well made. UV inks are firmly

Inks That Shrink
August 1, 2006

With the use of shrink-sleeve labeling for product decoration growing at a double-digit rate, suppliers of shrink film inks are developing a steady stream of products to carve out a piece of the action. But in addition to the normal adhesion issues that are common with non-porous film applications, shrink inks have several other factors to contend with that make their development more challenging. Some of these issues include distortion (cracking, delamination, etc.), blocking, coefficient of friction (COF), and in food and beverage applications, low odor. Demanding applications Shrink labeling is growing in popularity because it offers brand managers at least two advantages. It

Special Inks Make Cents
June 1, 2006

Specialty inks are just that—special. They can perform a multitude of functions for a package or its contents—from protection to jazzing it up, providing enhanced value in form, function, or both. In discussing this topic with Bob Lorenz, vice president of business development for Sun Chemical, what comes across loud and clear is the excitement that this category can generate, even when looking at the specialty inks that are more functional in nature. Sun Chemical offers a full gamut of specialty inks that can meet virtually any need. One can just imagine a brand manager sitting across from Lorenz as he runs down
