DRYING PHILOSOPHY: A GOLDILOCKS KNOB

0 Comments

Very few people wake up in the morning excited about dryer technology, but dryers are often a necessary part of a system-level solution for high-speed, aqueous inkjet printers.

During the printing process, the water in aqueous ink can be removed in two ways. Either a porous surface or coating is used to absorb the water and allow it to slowly evaporate over time without impacting the print, or the colorants need to be immobilized as soon as they hit the surface of the print substrate and dryers are then used for rapid evaporation of the water.
