UV offset ink is a solvent-free paste that cures in under a second under ultraviolet light. Unlike conventional ink, it prints on plastic, foil, and metal, not just paper. High gloss, wide color gamut, immediate finishing. No spray powder needed. No VOC emissions.

Fountain solution keeps the non-image areas clean while the ink does its job. Get the pH wrong, the conductivity wrong, the alcohol ratio wrong, the press run fights you. Formulation, chemistry, alcohol-free options, dosing, troubleshooting. The silent half of offset printing.

Offset ink is not liquid. It is a paste, thick and tacky, built for the split-second jump from plate to blanket to paper. Oil and water do not mix. That is the whole principle. Chemistry, classification, key properties, selection, storage. Everything to spec the right ink.
