ABSTRACT:
In a serial recording device (10) with a recording head (12), movable back and forth perpendicular to the feed direction (17) of a recording substrate (18), the recording head (12) performs a recording both during the forward motion (28) as well as during the return motion (32) in a bidirectional printing. For obtaining a good recording result, it is is required that the relative position of the grid pattern, generated during the forward motion (28), coincides with and matches the grid pattern, generated during the return motion (32) of the recording head. During a test recording process, a first test pattern (31) is recorded initially at least once during the forward motion (28), and then a second test pattern (33) is recorded at least once during the return motion (32) for a balancing of the relative position. An adjustment is performed in the sense that, during a further test recording process, the first test pattern (31) is disposed symmetrically relative to the second test pattern (33) depending on the relative position of the first test pattern (31) and of the second test pattern (33) to each other.
