PATTERN FORMING METHOD AND PATTERN FORMING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a pattern forming method and a pattern forming equipment which can simply form a pattern of high precision. SOLUTION: Ink retained on an intaglis 2 is once transferred on a blanket B, and then transferred on a board S to be printed. At this time, the steady flow viscosity of used ink is set to be in a range of 300-3000 poise, the critical surface tension of the blanket is set to be 20-30 dyne/cm, the hardness is set to be 40-80 deg., and the viscoelasticity tanδis set to be in a range of 0.05-0.20. The ink transferred on the board S to be printed is baked and made a pattern.
