PROBLEM TO BE SOLVED: To provide a curved surface printing method capable of beautifully connecting the boundary between images, when printing a second image adjacent to a first image on a curved surface as a print object. SOLUTION: The curved surface printing method comprises a process for producing a print sample by printing in an ink having a concentration (n) on a print surface printed in an ink having a concentration (m), measuring the color difference of the print sample and obtaining the correlation among the ink of 0 to 100% in concentration (m), the ink of 0 to 100% in concentration (n) and the allowable color difference, a process for printing the first image 21 in ink on the curved surface of the print object so that the edge 23 of the first image gradually thin in concentration toward the end, and a process for printing the second image 26 in ink adjacent to the first image so that the edge 28 of the second image gradually thin in concentration toward the end and overlaps on the edge of the first image, in which the concentration of the edge of the second image is set by adapting the concentration of the edge of the first image to the correlation obtained in the process for obtaining the correlation.
