Abstract
An image forming apparatus includes an image forming device, a gradation adjustment mark adder and a hardware processor. The hardware processor monitors and adjusts a gradation characteristic based on a result of scanning a gradation adjustment mark. The hardware processor makes a determination as to whether to form the gradation adjustment mark overlapping an image area of an image based on image data. If it is determined to form the gradation adjustment mark overlapping the image area, the hardware processor controls the gradation adjustment mark adder to add gradation adjustment mark information to the image data in the image area.
Claims12
An image forming apparatus, comprising:
- an image forming device which forms an image on a sheet based on image data;
- a gradation adjustment mark adder which adds gradation adjustment mark information to the image data so that a gradation adjustment mark is formed in addition to the image based on the image data;
- and
- a hardware processor which monitors and adjusts a gradation characteristic based on a result of scanning the gradation adjustment mark, in which a scanning section which reads the image formed on the sheet scans the gradation adjustment mark,
- wherein
- the hardware processor makes a determination, based on the image data, as to whether to form the gradation adjustment mark overlapping an image area of the image or whether to form the gradation adjustment mark in a non-image area, and
- in response to determining that the gradation adjustment mark is to be formed overlapping the image area, the hardware processor controls the gradation adjustment mark adder to add the gradation adjustment mark information to the image data in the image area.
A non-transitory computer readable medium storing a program which makes a computer of an image forming apparatus for forming an image on a sheet based on image data function as:
- a gradation adjustment mark adder which adds gradation adjustment mark information to the image data so that a gradation adjustment mark is formed in addition to the image based on the image data;
- and
- a hardware processor which monitors and adjusts a gradation characteristic based on a result of scanning the gradation adjustment mark, in which a scanning section which reads the image formed on the sheet scans the gradation adjustment mark,
- wherein
- the hardware processor makes a determination, based on the image data, as to whether to form the gradation adjustment mark overlapping an image area of the image or whether to form the gradation adjustment mark in a non-image area, and
- in response to determining that the gradation adjustment mark is to be formed overlapping the image area, the hardware processor controls the gradation adjustment mark adder to add the gradation adjustment mark information to the image data in the image.
