Abstract:
A system to print a security document and a control method thereof. The printing system simplifies a security procedure, and minimizes or prevents the security document from being illegally copied or copied without authorization. The printing system includes an input unit which receives an authenticator to copy the security document, and an output unit which determines whether the authenticator is equal to an authentication mark on the security document, and copies the security document in different ways according to the determined result.
Abstract:
A host apparatus, an image forming apparatus, and a diagnosis method for the image forming apparatus, the diagnosis method including: storing a printing image generated from print data according to a printing command; and generating a diagnosis image for the printing image based on the stored printing image and a defect image corresponding to a predetermined defect of the image forming apparatus.
Abstract:
An image processing method of an image processing apparatus, the method includes: discerning pixels to be processed on the basis of a preset reference pixel value in a scanned image that comprises plural pixels; drawing a pixel area including the pixels to be processed from the scanned image on the basis of a preset condition; and selecting whether to apply an image process to the pixels to be processed or the drawn pixel area on the basis of a percentage of the pixels to be processed in the drawn pixel area.

Abstract:
An apparatus and method for automatically processing an image that displays changes to the image at the back of a display region on a window of the foremost software are provided. The method of automatically processing an image uses automatic image processing software which is executed in a graphical user interface (GUI) operating system which displays a plurality of windows on a monitor screen. The apparatus and method include capturing the image at the back of a display region on a window of the automatic image processing software; automatically performing a specific image process on the captured image; and displaying the processed image on the display region.

Abstract:
A system and a method of adjusting colors of print data are provided. The system includes a printer driver converting a document transmitted from an application program into print data suitable for a printer and transmitting the print data to the printer. A soft proofing unit applies a soft proofing process to the print data converted by the printer driver. A display unit displays the print data obtained through the soft proofing process. A color lookup table (CLUT) supplies a color adjustment value to the print data when the print data is processed in the soft proofing unit. A system and a method of adjusting colors of print data is also provided to allow a user to accurately predict and adjust the colors of a printout, thereby obtaining the printout having the desired colors. Additionally, a method is provided of adjusting colors of print data to modify and apply a color lookup table (CLUT) for converting RGB image data into CMYK image data in a print driver by performing a soft proofing process and using a gradation chart for a preference of a user, thereby increasing user satisfaction of colors.
