Thu, 25 Aug 2016 08:00:00 EDTA printer performs a multi-pass printing including: (a) pass process executed with Ka number of nozzles; (c1) pass process executed with Kc1 number of nozzles; (c2) pass process executed with Kc2 number of nozzles; and (b) pass process executed with Kb number of nozzles. Kc1 and Kc2 are greater than or equal to Kb and smaller than Ka. An upstream gradient of dot recording rates of (c1) pass process is greater than a gradient of (a) pass process. A downstream gradient of (c1) pass process is the same as the gradient of (a) pass process. An upstream gradient of (c2)-pass process is the same as a gradient of (b) pass process. A downstream gradient of (c2)-pass process is greater than the gradient of the (a) pass process. Kc1 is greater than Kc2.
