Title:
PRINTING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/050074
Kind Code:
A1
Abstract:
The present invention provides a technology which is able to suppress re-transfer of a transferred photocurable ink to an intermediate transfer medium or the like, while suppressing photocuring of the ink on the intermediate transfer medium, and which enables the achievement of good multilayer printing. A printing method according to the present invention transfers a print pattern of a photocurable ink to a print-receiving material from an intermediate transfer medium, increases the viscosity of the photocurable ink by irradiating the print pattern, which has been transferred to the print-receiving material, with first light, and cures the photocurable ink by irradiating the print pattern, the viscosity of which has been increased, with second light. The first light contains light of a first wavelength; and the second light contains light of a second wavelength, which is shorter than the first wavelength, at a higher intensity than the first light. The photocurable ink contains: a polymer material that is solidified by means of polymerization; a first photopolymerization initiator which is reactive with light of the first wavelength; and a second photopolymerization initiator which is reactive with light of the second wavelength, while being not reactive with light of the first wavelength.
