摘要： A recording condition determining method executed by a recording device performing recording by a main scanning (P1, P2, P3, P4), in which while moving a recording head (15) in a main scanning direction (D1, D2), dots are ejected from nozzles (17) onto a recording medium (30), and a sub scanning, in which the recording medium is transported in a sub scanning direction (D3). The method includes a patch recording step of recording patches (45, 46, 47, 45-1, 46-1, 47-1) on the recording medium by overlap-processing in which the main scanning is performed on a partial region of the recording medium a plurality of times in an overlapping manner, the patch recording step being performed by recording the patches at a plurality of different positions in the sub scanning direction by a plurality of types of the overlap-processing under respectively different recording conditions, in a single recording job performed by the recording device. The method further includes a selection accepting step of accepting selection of a patch from among a plurality of the recorded patches, and a determination step of determining, as a recording condition of the overlap-processing of an actual recording, the recording condition of the overlap-processing corresponding to the patch selected in the selection accepting step.

摘要： A printing apparatus (1) includes a printing portion that performs printing by discharging inks onto a recording medium, a transporting belt (53) that includes a mounting portion (17) in which a test medium (200) on which a test printing is performed by discharging the inks is mounted before performing printing, and a guide portion (181) that guides the test medium (200) to the mounting portion (17) at the time of mounting the test medium (200) on the mounting portion (17). In addition, it is preferable that the test medium (200) have a higher stiffness than the recording medium.
