Spot and flood coating are two popular coating methods for digital print environments. Both aqueous- and ultraviolet (UV)-based solutions are available.
Kevin Chen, product manager, Duplo USA Corporation, says customers looking for an inexpensive way to enhance an image with a high-quality gloss, satin, or matte finish, or adding richness to its color while protecting it from scratches and scuffs can find a solution in flood coating. “Print providers can offer double the value by coating both sides of applications such as direct mailers, brochures, business cards, and book covers.”
On the other hand, spot coating is trending. “The primary use of spot UV coating is to produce a high-margin embellishment and value-added product in house that your customer can touch and feel,” suggests Chen.
The ability to coat larger output and the increased interest in digitally printed packaging generate additional interest.
