The Epson Pen & Crossword 16 Yellow Ink Cartridge uses Epson's all-pigment DURABrite Ultra ink which adheres to the surface of paper rather than sinking in, producing laser-like business quality prints on multiple paper types and grades. Ink dries instantly, allowing you to print on both sides of paper without any 'bleed-through' while saving on printing costs. Documents are smudge, water and highlighter resistant thanks to all-pigment ink system, making your prints durable and clear.
