摘要:
An image forming apparatus is constituted by a dark color image forming station for forming an image with such a toner of recording materials having the same hue and different lightness as has a lower lightness; a light color image forming station for forming an image with such a toner of the recording materials having the same hue and different lightness as has a higher lightness; and a control portion for effecting control so that an image to be emphasized by partly disappearing or by relatively and partly decreasing in density is formable substantially only with the toner having the higher lightness.

PROBLEM TO BE SOLVED: To provide a technique for reducing information leakage caused by color redevelopment of an erased toner.SOLUTION: An image formation apparatus according to the embodiment includes: an input part for inputting information of a print object; a first print part for printing with a toner that cannot be erased by an erasing device; a second print part for printing with a toner that can be erased by an erasing device; and a control part for controlling the information of the print object inputted by the input part so that at least keywords previously stored in a storage part is printed on the first print part and controlling information that is not printed on the first print part to be printed on the second print part.
摘要:
An image recording apparatus which accepts image data and records an image based on thus accepted image data on a sheet comprises storage means which stores predetermined patterns and means which records the patterns outside a recording area for the image, during recording of the image on the sheet.

PROBLEM TO BE SOLVED: To provide a printed material which is difficult to read by means of an image reader, and an image forming apparatus capable of outputting the printed material. SOLUTION: A printer 500a comprises a yellow unit 10Y, a magenta unit 10M, a cyan unit 10C, and a black unit 10K each for forming a visible image, an invisibility unit 10I for forming an invisible image (a code image), and a retroreflection unit 10R for forming a retroreflection image by using a retroreflection material. The printer 500a outputs a printed material formed by superposing a retroreflection image to a visible image on paper P. When the printed material is to be copied, a reflection light (an incident light) from a light source is returned to the side of the light source by virtue of the retroreflection characteristic of the retroreflection material so that it is possible to prevent the light from being incident on a CCD image sensor.

摘要:
The method involves determining printing conditions of a document/product, where the document is of analog, digital or passive type. Physical characteristics e.g. size, of cells of a form are determined based on the conditions so that a proportion of the printed cells showing a printing error that is due to printing irregularities, is higher/lower than respective preset values. Digital/text information is represented by varying appearance of the cells having the characteristics. The form is printed by applying the conditions, where the form detects a document copy that modifies the appearance. An independent claim is also included for a document securing device comprising a determination unit.
摘要:
An image formation system includes a medium-pattern-information-read-unit that reads pattern information of a surface of a medium; a pattern-information-image-creation-unit that creates a pattern Information image based on the read pattern information; and a print unit that adds the pattern information image to a print image to be printed on the surface of the medium and prints the print image on the medium.
摘要:
A copier that includes a reading unit to read a document to obtain an image and a printing unit configured to print the obtained image to obtain a copied document. The copier further includes a setting unit to set a setting for adding an image indicating that copying the copied document is inhibited and a controlling unit to control the printing unit so in a case where a document having an image indicating that copying the document is permitted subject to an input of authentication information is read to obtain an image and the setting is not set, the obtained image is printed subject to an input of the authentication information, and in a case where a document having an image indicating that copying the document is permitted subject to an input of authentication information is read to obtain an image and the setting is set, not printed the image.

PROBLEM TO BE SOLVED: To enhance recognition accuracy of a copy-prohibition pattern even when a copy-prohibited document has a density unevenness, and to enhance the security. SOLUTION: It is determined whether or not a job lock function is enabled (S604). It is determined whether or not the current mode outputs an image of a partial region of the document onto a recording paper sheet (S605, S606). When it is determined that the job lock function is enabled, and it is determined that the current mode outputs the image of the partial region of the document onto the recording paper sheet, an image of a region larger than the partial region is read in S608.

摘要:
PROBLEM TO BE SOLVED: To ensure sufficient confidentiality, by determining appropriately a shape of a see-through preventive pattern, which makes image data of a manuscript hard to be visible, and a printing position while toner is saved, deterioration of a consumable part is prevented, and paper feed trouble is reduced. SOLUTION: An image data reading unit for reading image data formed on a manuscript, an image processing unit for carrying out region separation for a region, where effective information of the read image data is located, and determining a shape of a see-through preventive pattern and a formation position of the see-through preventive pattern for each region separated by the region separation, and an image printing unit for printing the determined see-through preventive pattern on a region corresponding to any of region, where effective information of the manuscript is located, on the rear face of a recording paper with manuscript, which was already printed, based on the information on the formation position of the determined see-through preventive pattern are provided.
