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.

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.
