Abstract:
1. A registration adjustment method for adjusting errors in recording positions for use in a recording device having a plurality of recording units, each including a plurality of line-type recording heads, for recording divided recording images on a same recording medium using said plurality of recording units, neighboring recording units of which have an overlapping recording area where recording areas of said neighboring recording units overlap each other in end parts of the recording heads thereof, said registration adjustment method comprising the steps of: causing said plurality of recording units to record an inter-unit registration adjustment pattern for detecting errors in position between said neighboring recording units with one of the neighboring recording units used as a reference recording unit with respect to another of the neighboring recording units, and an intra-unit registration adjustment pattern for detecting errors in position among the recording heads of each recording unit with one of the recording heads thereof used as a reference recording head with respect to other recording heads thereof, said inter-unit registration pattern being recorded by the reference recording head of each recording unit without using the recording heads other than the reference recording heads, said intra-unit registration pattern being recorded by the reference recording head with other recording heads of each recording unit; accepting input of inter-unit registration adjustment values obtained based on the recorded inter-unit registration adjustment pattern and intra-unit registration adjustment values obtained based on the recorded intra-unit registration adjustment pattern; and storing in a storage area the inter-unit registration adjustment values and the intra-unit registration adjustment values; making an inter-unit registration adjustment based on the stored inter-unit registration adjustment values; and making an intra-unit registration adjustment based on the stored intra-unit registration adjustment values.
