INK

摘要

PROBLEM TO BE SOLVED: To provide ink for inverse printing provided with both moderate wettability and releasability to the surface of a silicone blanket, and formable of uniform thickness ink patterns free of unevenness and defects on the surface of printing objects such as a substrate.

SOLUTION: This ink has dynamic surface tension measured at 25°C by a maximum bubble pressure method of ≥16 to ≤23 mN/m when measured by setting the generation cycle of bubbles to 0.05 Hz; and ≥20 to ≤27 mN/m when measured by setting the generation cycle of bubbles to 10.0 Hz.
