Abstract: An inkjet printing method forming a decorative printed layer having a three-dimensional texture on a printing surface is described. The inkjet printing method includes: printing dots of curable ink that cure under a predetermined condition based on dot pattern data indicative of printed positions of the dots to be printed on the printing surface; and curing the printed dots. The dot pattern data indicates that: a distance between the adjacent dots becomes a distance where the adjacent dots before the curing are allowed to be maintained independently without bonding to one another in a first region; and the distance between the adjacent dots becomes a distance where the adjacent dots before the curing bond to one another in a second region different from the first region. Such a method may allow forming a decorative printed layer having a three-dimensional texture with a desired gloss level.
