Premium matte is the matte inkjet paper from Epson ColorWorks.
The material was marketed by Epson to ensure that labels would be available when the Epson ColorWorks color label printer was launched. Epson’s matte inkjet paper is a good quality inkjet material but cannot be ordered in your own sizes.
