Ink tank is designed for use with Canon Pixma iX7000 and MX7600. 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. 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.
