![]() ![]() Solvent inkjet inks for thermal inkjet technology are often used for printing pharmaceutical packaging. Industrial inkjet printing offers cost-effective printing for shorter production runs or customizing products. A craft brewer, for example, may want to personalize a beer can for a special occasion or a seasonal release. Inkjet printing is an effective solution for embellishing metal products. Common Metal Substrates for Industrial Printing Kao Collins produces specialty inkjet inks that can withstand bending up to about 180 degrees. Various inkjet inks are ideal for applications requiring flexible metals, such as aluminum wrapped around a pillar or other shape. Inkjet Printing on Flexible or Bending Metals Cationic ink doesn’t shrink when it cures. Non-cationic inks shrink and curl on a microscopic scale as it cures, making them a less durable solution because they are more susceptible to scratching and peeling. The light’s wavelength excites the photoinitiators added to the curing or hardening and locking it to the metal surface. When exposed to mercury arc or LED lamps, cationic inks continue curing after the initial exposure to the light. It may be more cost-effective because changing inks in printing equipment isn’t necessary.Ĭompanies specializing in printing on non-porous surfaces may choose to use energy-cured inks. Companies printing a wide range of products often apply primers rather than choosing specialty ink. There are limited options for printing on uncoated metals. Ink manufacturers can test, evaluate, and print samples for you. Whether a metal has a coating often determines the type of ink to use for best results.
