Method for analyzing positional deviation of head modules, program, and method for adjusting inkjet head

摘要

A method for analyzing positional deviation of head modules of an inkjet head having head modules connected and joined with each other includes: dividing a printing pattern and thereby creating division patterns; obtaining conversion factors of the nozzles of each division pattern; changing the number of nozzles used in calculation and thereby obtain a minimum value of a standard error of a positional deviation shift amount; changing the number of divisions of the division patterns and performing the calculation of the conversion factor and the standard error with the changed division patterns; determining the number of divisions and the number of nozzles with which the value of the standard error is minimal; and creating an analysis chart with the determined number of divisions and calculating the positional deviation shift amount based upon an average value of the positional deviation shift amounts of nozzles corresponding to the determined number of nozzles.
