Abstract
An image formation apparatus includes: a storage which stores a test pattern; and image formation sections which form an image of the test pattern on a medium. The image of the test pattern includes divided images formed by being divided into regions in a main scanning direction and a sub-scanning direction. Each of the divided images is formed by at least one preset image formation section out of the image formation sections. A total width, in each of the main scanning direction and the sub-scanning direction, of the divided images formed by each of the image formation sections is larger than the entirety of a corresponding width of the image of the test pattern.
Claims20
An image formation apparatus comprising:
- a storage;
- and
- a plurality of image formation sections each comprising plural rotation members, wherein
- a test pattern is stored in the storage;
- the plural rotation members form an image of the test pattern on a medium,
- the image of the test pattern comprises divided images formed by being divided into regions in a main scanning direction and a sub-scanning direction,
- each of the divided images is formed by at least one preset image formation section out of the image formation sections, and
- a width in each of the main scanning direction and the sub-scanning direction of the divided images formed by each of the image formation sections covers the entirety of a width of the image of the test pattern, wherein
- the width of the image of the test pattern in the sub-scanning direction is larger than a width of an image in the sub-scanning direction formed during two or more revolutions of one of the plural rotation members having a rotation period for image formation larger than that for others of the plural rotation members.
An image formation method comprising:
- reading a test pattern stored in a storage;
- and
- forming an image of the test pattern on a medium by image formation sections comprising plural rotation members, wherein
- the image of the test pattern comprises divided images formed by being divided into regions in a first direction and in a second direction orthogonal to the first direction,
- each of the divided images is formed by at least one preset image formation section out of the image formation sections,
- a width of the divided images in the second direction formed by each of the image formation sections covers the entirety of a width of the image of the test pattern, and
- the width of the image of the test pattern in the second direction is larger than a width in the second direction of an image formed during two or more revolutions of one of the plural rotation members having a rotation period for image formation larger than that for others of the plural rotation members.
