While most inkjet printing on cardboard projects are using black ink, a company may want its logo to reflect its identity through its brand color. These formulations are less opaque but absorb well into the box. For marking and coding with thermal inkjet systems (TIJ), many printers employ water-based pigment or dye-based inks.ĭye formulations are used most frequently in inkjet printing on cardboard. Marking and coding on corrugated boxes use black piezo inkjet inks, which are traditionally oil-based pigment inks and now an eco-friendly bio-based mineral-oil-free ink. Generally, most inks used for box printing are pigmented.

Various curing systems are used across the industry, depending on the ink: forced air, ambient air or dryer. The inks must dry on the substrate quickly in high-speed production systems yet remain fluid on the printheads to avoid costly downtime for upkeep. Inkjet ink manufacturers evaluate the substrate to deliver the best ink for the corrugated material.Ĭuring is another consideration in the ink formulation. These boxes often have a layer of semi-gloss white, or another color, paper over the corrugated cardboard. While many boxes are the traditional dull, brown, some businesses expect more and opt for boxes with a better finish for that branded look. Some box finishes require extra consideration when choosing an ink.
Printing on the glossy finish requires an ink appropriate for that substrate.
