8. A layered printing method of a three-dimensional relief layered ink-jet printer, which is suitable for the three-dimensional relief layered ink-jet printer of claim 1, and is characterized by comprising the following steps:
s1, the main control module obtains a plane design drawing of the three-dimensional embossment to be sprayed;
s2, the stereo scanner obtains the three-dimensional data of the stereo embossment to be sprayed and painted, and inputs the three-dimensional data into the main control module;
s3, obtaining vertical printing height according to the vertical distance between the highest point and the lowest point obtained by the three-dimensional data, setting the number of printing layers, dividing the vertical printing height into a plurality of equal parts, and drawing a contour map by using the three-dimensional data;
s4, overlapping the contour map and the planar design map to obtain a printing map of the layering area;
and S5, sequencing the layered region printing graphs from high to low, and printing layer by layer according to the sequence.
9. The layered printing method of the three-dimensional relief layered ink-jet printer according to claim 1, wherein the master control module controls the lifting module (3) to make the contour line corresponding to the printing pattern of each layered area coincide with the vertical height of the ink-jet module (5) when printing in the step S5.
