Pigment-based ink formulations having improved printhead lifetime |
| abstract |
An aqueous-based inkjet ink for a thermal inkjet printhead includes: a pigment; 2 to 90 ppm ammonium ions; and an ink vehicle. The ink has a pH in the range of 8 to 9.5 and exhibits improved lifetime in thermal inkjet printheads with minimal loss of print quality. |
