The Canon CLI-42 BK is a black ink cartridge that uses the ChromaLife100+ dye based ink to reproduce photographs in incredible detail. When used with Canon photo paper this ink creates deep black tones, shadows and contrast that is always super crisp and resists fading over time. The cartridge contains 13 ml of ink that can produce up to 65 A3+ images or up to 900 10x15cm photos. This cartridge and the other colours in the set are to be used with a Canon PIXMA Pro-100 printer and can be ordered individually or as a complete set from Just Ink and Paper.
