The High Resolution Color Moderate Use Cartridge (No.27) benefits from Lexmark's most advanced cyan, magenta and yellow ink formulations. For all the color inks Lexmark chooses to use dye-based inks because of their unique ability to create richer and brighter colors, a wider color ink spectrum and light fastness. The Lexmark 7 picoliter colors cartridge provides high quality photo quality without the need for a separate photo cartridge.
