When to use Photo Black vs. Matte Black Inks
A number of photo inkjet printers use two different primary black inks – Photo Black or Matte Black. Each is optimized for a certain type of inkjet media.
Use Photo Black for glossy, satin, and luster inkjet papers. Some fine art media like fiber based baryta also require the use of Photo Black inks. You will use Matte Black inks for cotton fine art and matte inkjet media. Matte papers are usually smooth and have a flat non-reflective surface.
Older Epson printers like the Epson R2400 and Epson R2880 require that you physically change the ink tank when you want to switch media types.
Newer Epson printers, and all Canon printers (with multiple black inks) have all of the ink tanks on the printer at one time. The machine will either automatically switch when you change paper settings, or it will do a short “ink swap” then proceed with printing.
