INKJET COATING METHOD

PROBLEM TO BE SOLVED: To provide an inkjet coating method capable of coating a construction base with a stable coating color.SOLUTION: There is provided the inkjet coating method which sequentially applies inkjet coating to a plurality of construction bases 1 by an inkjet coating machine 2 having a plurality of inks with different colors. A standard difference table that tables as standard difference data, the differences between standard injection color data which regulate injection output of a standard ink color and standard measurement color data of a paint color which is inkjet coated with the standard ink color, is preliminarily set. Offset data are preliminarily set in the standard difference table. Reference color data are set by applying inkjet coating to a reference base material. The adjustment of the injection output of the inkjet coating machine is carried out based on the difference between actually measured color data and the reference color data by obtaining the actually measured color data by sequentially applying inkjet coating to the construction bases 1. In this case, the injection output is adjusted considering the offset data.
