Summary
Anyone who works with inks has likely experienced these frustrating moments: after being stored for a while, the ink develops flocculation and sedimentation, rendering it unusable and wasting valuable resources; after printing, the ink dries slowly, causing the finished products to stick together and feel tacky, thereby slowing down production; the printed materials exhibit color distortion and are prone to fading, which damages the brand’s reputation; and even more troublesome is that, over time, the metal rollers of the printing press become corroded, leading to a sharp rise in maintenance and operational costs… The root cause of these issues lies in pigment selection. Given the characteristics of solvent-based gravure inks, pigments are subject to stringent, multi-dimensional requirements, with three core criteria:
1. Excellent dispersibility and storage stability: Gravure inks have relatively low viscosity, which necessitates that the pigments exhibit good dispersibility and flowability in the vehicle to ensure uniformity and stability of the ink. Moreover, during long-term storage, the pigments must not undergo flocculation or sedimentation, thereby preventing ink spoilage and associated losses.
2. Excellent solvent resistance: The ink system contains a high proportion of organic solvents, so the pigments must remain stable in these solvents without discoloration or fading, thereby preventing color distortion in printed materials and safeguarding product appearance and brand image.
3. Non-corrosive and compatible with printing equipment: During printing, the ink is in continuous contact with metal rollers; therefore, free acids in the pigment must be strictly controlled to prevent corrosion of the metal rollers, thereby avoiding equipment damage, reduced service life, and increased operation and maintenance costs.
