Inks
Pigments, resins, and additives for flexographic, gravure, offset, UV-curable, waterborne and screen printing inks across packaging, publication and industrial substrates.
Printing ink chemistry differs sharply from general coatings: ink films are thin (typically 1–8 microns dry), substrates range from absorbent paper to non-absorbent films, and process speeds in modern flexo and gravure presses leave milliseconds for each ink station to set or cure. The result is a tightly constrained formulation space where pigment dispersion quality, resin compatibility, and rheology under high shear are decisive.
Coatingsink supplies the full ink raw-materials portfolio: organic and inorganic pigments matched for solvent or waterborne dispersion, NC and acrylic resins for solvent flexo, hybrid ester systems for gravure, polyester acrylates for UV, and the wax / slip / surfactant additives that fine-tune transfer and rub resistance. Whether you formulate flexible packaging inks, narrow-web label inks, news offset, or UV inkjet, our products are matched to specific press conditions and substrate sets.
How to Choose Inks
Key selection criteria buyers use when specifying inks for trade and OEM formulations
Substrate Compatibility
Paper / corrugated tolerates a wide formulation window — water-based or solvent. Non-absorbent films (BOPP, PET, PE) need surface-energy-matched binder systems and adhesion promoters. Aluminum foil and metallized films need primer compatibility and heat-seal resistance.
Pigment & Dispersion
DPP red, quinacridone, phthalo blue/green, and benzimidazolone yellows give the lightfastness and color strength packaging inks need. Ensure pigment grade matches the binder polarity — solvent-borne dispersions don't translate to waterborne without re-dispersing.
Cure & Setting Speed
Solvent flexo at 300+ m/min needs binders with rapid solvent release (NC, low-MW polyamide). UV inks need fast-curing photoinitiators (TPO, 184) tuned to LED or mercury lamp output. Heatset offset uses oxidative-drying alkyd-modified resins.
Adhesion & Mechanical
Match resin acid value and Tg to substrate flexibility. Add silicone slip additives where coefficient-of-friction targets are tight. PE wax for rub resistance, PTFE micropowder for premium scuff resistance on retail packaging.

Inks FAQ
Nitrocellulose (NC, RS quarter-second or half-second grades) is the dominant binder for solvent flexo on film and foil — fast solvent release, excellent transfer. Polyamide resins (low-MW soft grades) co-blend with NC to improve film flexibility and adhesion to BOPP. Acrylic-modified resins are used for retort or low-odor systems.
