Method of setting density for image recording apparatus
First Claim
1. A method of setting recording density in an image recording apparatus, the method comprising the steps of:
- supplying a constant intensity light beam;
varying the supplied constant intensity light beam to provide a plurality of amounts of light;
recording a sample image having a plurality of regions, each having different densities, by scanning a photosensitive material with the plurality of amounts of light, each of the different densities corresponding to a respective one of the plurality of amounts of light;
measuring the different densities of the sample image;
obtaining a relationship between the measured different densities and the corresponding plurality of amounts of light; and
setting light-amount adjusting means so that an image having a desired density is recorded according to the obtained relationship.

Abstract
In a method of setting density for an image recording apparatus, an image for measurement having a plurality of regions having different densities is recorded by scanning a photosensitive material with a light beam having a constant intensity while changing light intensity using a light-amount adjusting device. The relationship between the amount of adjustment by the light-amount adjusting device and the density of the recorded image is obtained by measuring the densities of the respective regions of the recorded image for measurement. The light-amount adjusting device is set so that an image having a desired density is obtained according to the obtained relationship.
