20090152024 | ELECTRIC PAPER READING SYSTEM - Objects of the present invention are to facilitate filling out by hand an electronic paper and to realize digitization of contents with which the electronic paper is filled out by hand with a simple structure. A read image is obtained by optically reading a reading-object of the electronic paper. Based on the document information written on the electronic paper and writing-conditions during document writing, which are represented by the document information, a display image of the document in accordance with the read image information is formed. A written image is separated and extracted by converting a density only of pixels among the respective pixels of the read image, whose densities vary in accordance with the document writing and which correspond to a portion, to which ink of a pen for the handwriting is not adhered. | 06-18-2009 |
20090244159 | INK JET RECORDING APPARATUS AND METHOD OF INK JET RECORDING - A first image to be recorded on a first surface is divided into front and rear half regions. Obtained thereafter is front-side ink volume and rear-side ink volume necessary for recording these half regions on the first surface. Among these half regions, the one having more ink volume is recorded in the first place. In the event of recording the rear half region in the first place, the first image is turned upside down and recorded on the first surface of the recording paper being fed in a forward direction. Alternatively, the first image is recorded on the first surface of the recording paper being fed in a backward direction. After the ink has dried on the first surface, the recording paper is reversed back to front and fed in the forward direction, and a second image is recorded on a second surface. | 10-01-2009 |
20100141726 | IMAGE FORMING METHOD - An image forming method includes: moisture-controlling one surface of an inkjet recording medium having an air permeability of 300 seconds or more; feeding the moisture-controlled inkjet recording medium onto a conveyance path in a state where the moisture-controlled inkjet recording medium is curled such that a surface of the moisture-controlled inkjet recording medium that is curved inwards faces the conveyance path for conveying the inkjet recording medium; conveying the fed inkjet recording medium while adhering the inkjet recording medium by suction onto the conveyance path; and forming an image by applying ink by an inkjet method on the inkjet recording medium adhered by suction to the conveyance path. | 06-10-2010 |
20100207975 | INKJET RECORDING METHOD AND RECORDED ARTICLE - An image is recorded by ejecting two or more ink compositions on a porous layer that contains inorganic microparticles and a water-soluble resin and has a porosity [%] of 50% or more with a maximum total ejection amount (mL/m | 08-19-2010 |
