摘要:
An image forming apparatus includes a carriage that includes a head including a black nozzle array in which a plurality of nozzles are arranged and a color nozzle array in which a plurality of nozzles are arrange, the black nozzle array being disposed at a position shifted in the sub-scanning direction downstream in a medium conveying direction with respect to the color nozzle array; a conveying unit configured to convey a recording medium in a sub-scanning direction; and a control unit. The control unit forms an image by the color nozzle array in a main scanning in one direction, relatively moves the recording medium to a subsequent main-scanning position thereafter, and forms an image by the black nozzle array on the image formed by the color nozzle array in a following main scanning in the other direction so as to complete an image for one scanning area.

An image forming device forms an image on a recording sheet by bidirectional recording. In the image forming device, a control part controls the image forming device. The control part includes a distance changing part that changes a sheet transporting distance for transporting the recording sheet after a forward movement of a recording head to a first transport distance and changes a sheet transporting distance for transporting the recording sheet after a backward movement of the recording head to a second transport distance, and a nozzle changing part that determines inactive nozzles which do not discharge a recording liquid among nozzles of the recording head alternately for one of the forward movement and the backward movement of the recording head.

An image processing method of processing image data includes a color space conversion step of converting an input color signal of image data into an output color signal having cyan (C), magenta (M), and yellow (Y) values; a black generation/under color removal step of converting the CMY values into cyan (C), magenta (M), yellow (Y), and black (K) values by adding a black (K) value and decreasing the CMY values so that portions of cyan (C), magenta (M), and yellow (Y) recording liquids used to form the image data are replaced with a black (K) recording liquid; and a total amount control step of controlling amounts of cyan (C), magenta (M), yellow (Y), and black (K) recording liquids calculated from the CMYK values so that a total amount of the CMYK recording liquids per unit area on a recording medium does not exceed a predetermined total amount limit.
摘要:
A disclosed image processing apparatus performs an image processing operation to execute double-side printing on both sides of an image forming medium. The image processing apparatus forms a dot font including a dot pattern of a character in a character image that has undergone a halftone process using a predetermined coefficient for mitigating show-through when the double-side printing is performed; forms a correction dot for making a correction to reduce step-like irregularities along an outline portion of the character in the character image, which correction dot is formed based on an arrangement position, a color, and a dot size of the correction dot for reproducing a gradation that has undergone the halftone process using said predetermined coefficient; and combines the dot font and the correction dot.
