PROBLEM TO BE SOLVED: To provide a printer which can stably form a uniform printing pattern on a printed board without inspecting the printed board.SOLUTION: A printer provided with a rotary plate cylinder 102 on which a printing plate 101 is installed, a movement surface plate 107 on which a printed board 106 is placed, and an ink supply device for supplying ink to the printing plate, further comprises: an inspection roll for transferring the ink supplied to the printing plate; an imaging device for imaging the ink transferred to the surface of the inspection roll 108; means for calculating an average value of chromaticity values of all the pixels with respect to the image of the surface of the inspection roll imaged by the imaging device; means for specifying the position of the pixel with the maximum absolute value of the difference between the average value and the chromaticity value on the inspection roll; and means for adjusting the inclination angle of the plate cylinder with respect to the printed board 106 on the basis of the difference between the average value and the chromaticity value of the pixel and the position on the inspection roll. |
