Why Update Media Models? ® Triangle Digital uses higher quality pigments creating a large color gamut and 30% more longevity. ® By Updating the Media Models you bring your printer to a neutral gray scale and adjusted ink limits for consistent color and dry times. 5/1/2003 KWitte Triangle Digital

How long will this take? ® To “Update” a current media model will take about 15 minutes ® To build from scratch will take about 45 minutes ® This does not include loading the various medias. 5/1/2003 KWitte Triangle Digital

What is the difference between Media Models and ICC profiles? ® Media Models are the foundation to creating a ICC. ® Media Models include Dark Ink restriction, Linearization and Ink Limits ® These are all related to the ink, media, speed and resolution of your printer. 5/1/2003 KWitte Triangle Digital
