A printing method and a printing system are provided where a printing property of the printing system is stored, a printing compatibility of a printing data of an object to be printed is determined by comparing a data property of the printing data with the stored printing property of the printing system, and the determined printing compatibility is displayed to a user. Accordingly, a printing system and a printing method, which are capable of preventing user inconvenience and waste of resources due to re-printing are provided.

Printing system and printing method

A terminal device having a correction function for natural color and a method thereof are provided for creating an image closest in color to the natural color. A priority storing unit stores at a reference color data area a range of natural colors which are colors of objects existing in the natural world. A color editing unit corrects natural color image data corresponding to the natural color area, based on a command for correcting the natural area existing in a predetermined image from the user. A controlling unit decides whether the natural color image data corrected by the color editing unit is included in the reference color data area.

Terminal device having correction function for natural color and method thereof

An apparatus includes a gray converter to convert an inputted color image to be printed into a gray conversion image and to outputs the gray conversion image a difference calculator to calculate a at least one difference value between at least one color channel image with respect to the color image and the gray conversion image; and a gray reviser to revise the gray conversion image based on the at least one difference value and to output a gray conversion image.

Image forming apparatus and image forming method capable of revising gray image

An apparatus includes a gray converter to convert an inputted color image to be printed into a gray conversion image and to outputs the gray conversion image a difference calculator to calculate a at least one difference value between a at least one color channel image with respect to the color image and the gray conversion image; and a gray reviser to revise the gray conversion image based on the at least one difference value and to output a gray conversion image.

Disclosed are a color management method, an apparatus thereof and a color management computer program for executing the method that enable a user to conveniently and easily select and/or change colors desired by the user in diverse ways. The color management method includes displaying a color scheme list that is a list of color schemes for providing a standard for converting the colors that constitute an image, and if a selection manipulation of one among the color schemes that constitute the displayed color scheme list is input, storing the color scheme selected by the selection manipulation.

Color management method and apparatus thereof

A method of converting a color image into a monochromatic image, includes converting the color image into a color space representing brightness values and attribute values of pixels constituting the color image, converting the color image into the monochromatic image based on the brightness values of the pixels, and modifying brightness values of pixels of the monochromatic image based on eigenvalues corresponding to the attribute values of the pixels of the color image.
