Exclusive to the PIMXA iX7000 Inkjet Business Printer and MX7600 Office All-In-One Printer, the PGI-9 Clear Ink Tank is the gateway to Canon's proprietary PgR Technology. PgR produces professional document and image quality on plain paper. Before the LUCIA Pigment Inks are fired onto the plain paper, a thin coat of PGI-9 Clear Ink is applied to the entire surface of the paper. Then, the PGI-9 Clear ink reacts with the PGI-9 color inks to produce professional document output with anti-paper curling, anti-bleeding and higher sharpness. At last, true professional document quality at home with inkjet printers. Plus, Canon's individual ink system can help increase efficiency by reducing waste and saving you money since you'll only be replacing the color that runs out.
