4. What is the shelf life of ink cartridges?

Ink Cartridge Shelf Life (Unopened):

● Water-based ink: ≥ 12 months from the filling date

● Solvent-based (quick-dry) ink: ≥ 9 months from the filling date

These estimates assume the cartridges are stored under proper conditions. Good storage (cool, dry, and sealed) can help extend shelf life beyond the standard period.

Usage Life (After Printing):

The actual usage duration of an ink cartridge depends on several factors:

● Grayscale settings: Higher grayscale settings consume more ink per print.

● Complexity of printed content: images, logos, and large text blocks use more ink than simple characters.

● Surface material: Ink consumption may vary depending on the absorbency and texture of the printing surface—even with identical content.

● Test data: 800,000 characters (12.7mm ink cartridge prints at 3mm height); 1.3 million characters (25.4mm ink cartridge prints at 3mm height)
