PURPOSE:To prevent an original printing plate from being contaminated due to outflow of a contaminated rinsing liquid into the next step, by a method wherein an upper roll of feeding rolls is made to be an end edge part feeding roll, and an air squeezing part is provided on the downstream side of a printing plate feeding passage at a scraping part provided in proximity to an outlet of the first rinsing step. CONSTITUTION:A printing plate is fed without contaminating an image surface of the plate by using the end edge part feeding rolls 20. The air squeezing part 21 for squeezing a rinsing liquid present on the printing plate surface is provided in proximity to the outlet of the first rinsing step B, and a brushing roll 6A is rotated in the same direction as the printing plate feeding direction. Accordingly, a liquid reservoir can be provided between the roll 6A and the air squeezing part 21, it can be contrived to enhance squeezing property, and the contaminated rinsing liquid is prevented from being carried to the second rinsing step. |
