Lenticular printing method for lenticule on demand through ink jet

The invention discloses a lenticular printing method for a lenticule on demand through ink jet, which comprises the following steps of: A, inputting a print containing a printed lenticule image into an inkjet device; B, according to requirements on position and shape of the printed lenticule image, scanning row by row in a printed lenticule image area by using the inkjet device, jetting liquid transparent ink, and depositing the ink into lines so as to form a liquid plane; C, performing ultraviolet (UV) irradiation on the liquid plane to obtain a lenticule imaging layer L1; D, judging whetherthe thickness of the lenticule imaging layer L1 reaches the set threshold value d, if so, executing a step E, otherwise, repeatedly executing the step B and the step C; E, repeating the step B on thecured lenticule imaging layer L1 to obtain a lenticule curve layer L2; F, judging whether the thickness of the lenticule curve layerL2 reaches the set threshold value s, if so, executing a step G, otherwise, repeatedly executi
