| 20080239336 | OPTICAL SCANNING DEVICE, OPTICAL SCANNING METHOD, AND IMAGE FORMING APPARATUS - A light-source drive control unit divides each pixel of the image data into a plurality of subpixels, deletes certain subpixels from the image data in accordance with predetermined correction data, shifts remaining subpixels in the sub-scanning direction thereby obtaining reduced image data, and controls a plurality of light sources based on the reduced image data in such a manner that one line of the subpixels is formed with a light beam emitted from a corresponding one of the light sources. | 10-02-2008 |
| 20090066976 | PRINTING APPARATUS - A printing apparatus free from contamination of dust into a coated layer is provided. A printing apparatus of this application includes a first ejecting head and a printing head. The first ejecting head is located on a leading side in a moving direction D of the printing head. Since electric charge is removed from an object to be printed and dust is removed therefrom, by blowing an electric charge-removing gas through the first ejecting head before an ink lands on the object to be printed, dust does not contaminate a coated layer. In addition, since a suction hole is arranged between an ejecting hole and a nozzle zone, a stream of the electric charge-removing gas is not formed in the nozzle zone, and thus a meniscus of nozzles is not disturbed. | 03-12-2009 |
| 20090080002 | INKJET RECORDING APPARATUS, IMAGE PROCESSING METHOD, STORAGE MEDIUM, PIGMENTED INK, AND RECORDED MATTER - 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. | 03-26-2009 |
| 20100085585 | DIGITAL IMAGING OF MARKING MATERIALS BY THERMALLY INDUCED PATTERN-WISE TRANSFER - An imaging system including an image receiving structure including a material layer having a tunable energy transfer characteristic; and an energy source to emit an energy beam at the material having the tunable energy transfer characteristic such that marking material is pattern-wise transferred to the image receiving structure. | 04-08-2010 |
| 20100141969 | Method and Apparatus for Making Liquid Flexographic Printing Elements - A system and method for producing a flexographic relief image printing plate from a liquid photopolymer printing blank. The system comprises one or more apparatuses for performing steps to produce the relief image printing plate which are selected from the group consisting of a) a glass setting apparatus for setting a desired gauge of the relief image printing plate, b) an apparatus for controlling UV exposure of the printing plate during an exposure step, and/or c) an apparatus for automatically performing a masking exposure of the printing plate. A microcontroller is operatively connected to the one or more apparatuses and includes software for controlling the operation of the one or more apparatuses and data storage means for storing data relating to the at least one or more apparatuses. A user interface is operatively connected to the microcontroller and to the one or more apparatuses and comprises means for entering data into the data storage means and means for selecting information relating to the one or more apparatuses of the platemaking system. | 06-10-2010 |
| 20120206738 | DEVICE AND METHOD FOR IMPROVING XEROGRAPHIC VOLTAGE UNIFORMITY FOR AN IMAGE RECORDING APPARATUS - An image recording apparatus including a memory element and a processor for a specially programmed general purpose computer. The memory element stores correction data for a plurality of locations on a photoreceptor for the image recording apparatus. The processor is for: inducing a charge on the photoconductive layer; receiving image data including, for said each location in the plurality of locations, a first or second desired voltage level; calculating, using the correction and image data, respective desired output power levels for a LED printbar for the apparatus, aligned with the plurality of locations, to discharge each location to the one of the first or second desired charge level, the respective desired output power levels selected to compensate for variances of respective induced charge levels at the plurality of locations; and supplying respective power inputs to the plurality of LEDs to generate the respective desired output power levels. | 08-16-2012 |
| 20120206739 | SYSTEM AND METHOD FOR ADDING DATA TO A PRINTED PUBLICATON - Systems and methods for adding data to a printed publication are provided. One system comprises a data source for providing the data, a processing circuit, and an energy source. The processing circuit is configured to retrieve the data from the data source and to control the energy source to at least partially ablate the printed publication based on the data. The publication is printed by a web offset printing press as the substrate travels through a plurality of print units of the web offset printing press. The processing circuit is configured to control the energy source to ablate the printed publication in-line with its production on the print units. | 08-16-2012 |
| 20130194592 | ULTRASHORT LASER MICRO-TEXTURE PRINTING - Systems and methods for providing laser texturing of solid substrates are disclosed. The texturing may be used to provide grayscale images obtainable from substrates, which may include steel, aluminum, glass, and silicon. In some embodiments, images may be obtainable from the substrate by modifying the reflective, diffractive, and/or absorptive features of the substrate or the substrate surface by forming random, periodic, and/or semi-periodic micro-structure features on the substrate (or substrate surface) by an ultrafast laser pulse train. The ultrafast pulse train may be modulated in order to vary, for example, optical exposure time, pulse train intensity, laser polarization, laser wavelength, or a combination of the aforementioned. The ultrafast pulse train and the substrate may be scanned with respect to each other to provide different optical energies to different regions of the substrate (or substrate surface). In some embodiments, the image is provided by making one or more passes of the ultrafast laser pulse train relative to the substrate. | 08-01-2013 |
| 20130222821 | METHOD AND APPARATUS FOR CONTROLLING COLOR REGISTRATION SENSORS - A method and apparatus for controlling registration sensors are provided, in which a transfer unit transfers an electrostatic latent image onto a printing medium, at least one registration sensor senses image alignment errors by irradiating light to the transfer unit to sense reflected light, a sensor data storage unit stores characteristics data of the respective registration sensors, and a sensor control unit controls the registration sensors based on the characteristics data of the respective registration sensors, wherein the registration sensors are placed into the transfer unit. Accordingly, time for performing an algorithm of color registration can be reduced, and registration can be achieved correctly in a short time, irrespective of a set frame of the image forming apparatus. | 08-29-2013 |
