The Canon GI-43 is a grey dye-based ink bottle designed specifically for the PIXMA G540 and G640 ink tank printers. With a 60ml capacity, this Japanese-made ink allows you to print up to 3,800 pages, making it a practical choice for those who frequently print photos or documents requiring subtle shading and precise grey tones. Its chemical composition is balanced with a pH between 8 and 9 and a viscosity of 1-5 mm²/s, ensuring a consistent flow through the print head. This stability helps you maintain reliable print quality over long periods, while the secure bottle design makes refilling your printer's tanks simple and clean.
