Abstract:
1. A method of ink application on a substrate having a plurality of reference marks, comprising: a reference-mark measuring step of setting a plurality of divided areas on the substrate by virtually dividing the substrate along a plurality of virtual lines connecting the plurality of reference marks and measuring positions of the plurality of reference marks in each of the divided areas, the divided areas being continuous; a gravity-center deviation-amount acquisition step of acquiring a deviation amount between a gravity center of a measured figure defined by the positions of the plurality of reference marks obtained in the reference-mark measuring step and a gravity center of a designed figure defined by positions of a plurality of designed reference marks by comparing the gravity center of the measured figure and the gravity center of the designed figure; an applied-position acquisition step of acquiring a corrected applied position by shifting and correcting a designed applied position on the basis of the deviation amount between the gravity centers; and an ink application step of applying ink onto the substrate by an on-demand printing method according to the corrected applied position.
