Abstract
Official abstract text for this publication.
A luminance value for a second printing medium that has been obtained by reading a pattern image formed on the second printing medium different from a first printing medium is converted into a corresponding density value on the first printing medium. Calibration for the first printing medium can then be performed using the second printing medium.
First claim
Opening claim text (preview).
What is claimed is: 1. An image forming apparatus comprising: an image forming unit which forms a pattern image on a printing medium; a first conversion unit which converts a luminance value obtained from the pattern image formed on a first printing medium into a corresponding density value on the first printing medium, said first conversion unit including a first table used to convert a luminance value for the first printing medium into a corresponding density value on the firs…
