An image processing method for an image forming apparatus which is capable of performing double face printing is provided, wherein color space transformation processes that differ between single face printing and double face printing are performed. In addition, an image processing method for an image forming apparatus which is capable of performing double face printing is provided, wherein input tone transformation processes and adhering recording liquid quantity limiting processes that differ between double face printing and single face printing are performed.
摘要:
A disclosed image forming apparatus is capable of forming an image using a black recording liquid and at least one color recording liquid and generating image data on an image to be output. When an input image is black, the image data is generated for forming the image with the black recording liquid and using the color recording liquid for the image.
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.

摘要:
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 inkjet recording apparatus for performing recording by jetting a recording liquid onto a recording medium includes an image processing unit configured to obtain an output halftone level by performing halftone processing on input image data, to select a dot arrangement order according to the obtained output halftone level, and thereby to generate dot data where dots are arranged in a grid-like pattern. The disclosed inkjet recording apparatus is configured to use a pigmented ink as the recording liquid when the recording medium is a commercial printing paper, and to record the dots in a staggered arrangement where positions of the dots in odd/even-numbered columns or odd/even-numbered rows in the dot data are shifted in a sub-scanning direction or in a main-scanning direction.
摘要:
An image processing apparatus for converting input image data into output image data for an image forming apparatus configured to output an image with the use of coloring material, which includes a unit configured to perform a coloring-material usage amount reduction process of converting the input image data into the output image data such that an amount of the coloring material used for color-printing the input image data becomes a target coloring-material usage amount defined based on a monochrome-printing coloring-material usage amount required for monochrome-printing the input image data.
