TEST PRINT, TEST PRINT PRODUCTION METHOD, AND OPTICAL QUANTITY CORRECTION METHOD USING TEST PRINT

摘要

PPROBLEM TO BE SOLVED: To provide a production technique of a test print for falling down correction of an exposure unit. PSOLUTION: The test print includes a test pattern arranging a first block comprising: a region having a first density value, being a band-like region of a first scanning direction, and having first width in a second scanning direction; and a region having a second density value, being the band-like region of the first scanning direction, and having the first width in the second scanning direction, and a second block comprising: a region having the first density value, being the band-like region of the first scanning direction, and having second width in the second scanning direction; and a region having the second density value, being the band-like region of the first scanning direction, and having the second width in the second scanning direction at a prescribed rate. The test pattern includes: a reference pattern formed by regarding the first scanning direction as a main scanning direction and regarding a second direction as a sub-scanning direction; and a comparison pattern formed by a first scanning direction as the sub-scanning direction and regarding the second direction as the main scanning direction.
