Why Does HP Favor Pigment-Based Inks?

If you pay attention to HP’s recently launched printing devices, you will notice that pigment-based ink has always been its core option. Even when some models use dye-based ink alongside it, pigment-based ink still sees far more frequent application.

High Utilization of Pigment-Based Inks

Why is HP so partial to Pigment-Based Inks?

1. Adhesion Performance Pigment-based ink consists of tiny insoluble solid particles. After printing, it adheres firmly to the surface of print media, delivering outstanding water-proof and light-fast properties. In contrast, dye-based ink is a fully dissolved molecular solution. It has poor water resistance and tends to fade when exposed to prolonged sunlight, making printed works hard to preserve over long periods.

2. Particle-Size Performance The biggest drawback of early Pigment-Based Inks was particle sedimentation, which would easily clog printheads and ink supply pipelines. HP Vivera pigment-based ink addresses sedimentation and clogging issues through electrostatic encapsulation technology, leveraging mutual repulsion of negative charges. It also enhances image glossiness via multi-ink color combinations and expands the printing color gamut.

3. Rich Color Reproduction In terms of color performance, HP six-ink models add matte black and gray pigment inks, together with photo black ink. The gray ink enables soft tone transitions and fine detail rendering, and prints sharp gray lines. The full ink set can render authentic black-and-white visuals and retain shadow details in color images. Even on glossy media, it produces deep black and standard neutral gray, greatly improving the professional clarity of printed outputs.

OBOOC pigment-based ink features a refined nano-particle formula. It ensures smooth and stable ink output and resists sedimentation and clogging even after long-term storage. It is water-proof, UV-resistant, scratch-proof and fade-proof. It delivers vivid saturated colors, a wide color gamut and lifelike fine image details. It dries instantly upon printing and resists ink bleeding. Compatible with a wide range of HP and Epson printers, it enables long-term preservation for both engineering drawings and photos with excellent cost-performance.
