Title:

ADJUSTMENT OF DISPLACEMENT OF RECORDING POSITION DURING PRINTING USING HEAD IDENTIFICATION INFORMATION ABOUT PRINT HEAD UNIT

Document Type and Number:

WIPO Patent Application WO/2000/047416

Kind Code:

A1

Abstract:

The displacement of the dot recording position in the direction of horizontal scanning during printing is mitigated taking the characteristics of the print head into consideration so as to improve the quality of image. Head identification information preset according to the characteristics concerning the positional displacement of the dots formed by the print head in the direction of horizontal scanning is readably provided in a print head unit. The adjustment value for reducing the displacement of the recording position in the direction of the horizontal scanning is determined according to the head identification information, and the recording positions of the dots in the direction of horizontal scanning are adjusted by using the adjustment value.
