摘要:
There is disclosed an image forming apparatus for recording an original image read by a reading unit (16) on a recording medium using a recording head (37) having an array (117,118,119,120) of a plurality of recording elements. The apparatus includes pattern forming unit (130) for forming, on the recording medium, a test pattern having an area larger than an array range of the plurality of recording elements using the recording head (37) in accordance with a predetermined operation, a detection unit for causing the reading unit to read the test pattern formed on the recording medium by the pattern forming unit (130) in accordance with a predetermined operation, and detecting a density distribution within the array range of the plurality of recording elements, a generation unit for generating correction data of a drive condition for uniforming a density during image formation on the basis of the density distribution detected by the detection unit in correspondence with the plurality of recording elements, and a guide unit for display the predetermined operations on a display unit.
摘要:
When a reduction recording is made by using a portion (n1 to n96) of a plurality of recording elements (n1 to n128) and a test pattern is recorded, a recording element (n96) of one end of a recording element array is positioned next to a recording element (n1) of the other end. As a result, in a recording apparatus by using a recording head provided with a plurality of the recording elements, a suitable correction of shading is made in a reduction recording mode.

Provided are an image printing method and apparatus in which printing is made possible in a multiscanning mode for printing the same line using a plurality of printing elements of a printing head (2a) in order that uneven density caused by a variance in the printing elements may be rendered inconspicuous. When the multiscanning mode is designated, a plurality of nozzles of the printing head (2a) are divided into a plurality of blocks (A,B,C,D), the nozzle blocks used are changed over every scan of the printing head (2a), and the image of the printing width (band) printed using all of the nozzles is printed by causing the printing head (2a) to perform scanning a plurality of times.
