Inkteknologi

Inkteknologi refers to the science and engineering of inks and ink-based processes. It encompasses formulation, rheology, adhesion to substrates, drying and curing, and performance in printing, coating, and functional applications. It spans chemistry, materials science, and process engineering, with emphasis on compatibility between ink, substrate, and printing method.

Inks vary by colorants (pigments, dyes), media (water-based, solvent-based, UV-curable), and functional additives. Key classes include graphics inks for printing, textile inks, conductive inks for printed electronics, and bioinks for tissue engineering. Core properties include viscosity, surface tension, particle size, drying and curing behavior, and outdoor durability. Common production methods include inkjet, gravure, offset, screen printing, and flexographic.

Applications span traditional graphic arts and packaging, textile decoration, flexible electronics and sensors, printed circuits, biomedical and biofabrication, and 3D printing with functional inks. The field emphasizes sustainable formulations and low-emission processes, water-based systems, and recyclability of substrates.

Challenges and outlook focus on balancing performance and cost, ensuring print quality, adhesion, and durability; safety, environmental impact, and regulatory compliance; standardization and testing methods. Ongoing research aims to expand material choices, reduce solvents, improve printing on diverse substrates, and develop standardized metrics for printed materials.
