Overview

The Canon CLI-42 GY Gray Ink Tank is one of eight individual ink cartridges in the ChromaLife100+ system designed for the Canon PIXMA Pro-100 and Pro-100S professional photo printers. Its role in the ink lineup is critical: by providing a dedicated gray channel, it enables the printer to produce smooth, neutral grayscale tones and subtle tonal gradations that would be difficult to achieve by mixing other colors. This makes it especially valuable for photographers who print black-and-white work or images with significant shadow and highlight detail.

As a genuine Canon ink, the CLI-42 Gray is formulated to work in concert with the printer's other seven inks and Canon's photo papers to deliver ChromaLife100+ longevity—prints that resist fading and maintain color accuracy over time. The individual tank design is both a convenience and a cost consideration: you only replace the specific color that runs out, but maintaining a full set of eight cartridges represents an ongoing investment. For PIXMA Pro-100 users who demand accurate color and professional-grade output, the CLI-42 Gray is an essential part of the system.
