The latest developments in the inkjet ink field are the latex inks and resin-based inks. Both ink systems use water as the main ingredient but the carrier for the pigments is either latex or resin-based. Latex inkjet printers using these types of inks also need heaters built into the printer, so the media becomes receptive to the ink and also to allow the ink to dry properly. Since the inks are water-based there is no need for extra ventilation to remove any harmful substances emanating from the printer. The water-based formulations of latex inks reduce the impact of printing on the environment. They produce durable printing for outdoor and indoor applications. Prints look very good for signage applications.
