摘要： A controller in a one-side printing mode moves movable rollers to form a one-side printing route and moves a second head unit so that the second head unit faces a front side of a web. The controller then controls a first head unit and a second head unit to print images of respective pages on the front side of the web while transferring the web at a transfer speed twice as fast as that in a both-side printing mode.

摘要： Using a plurality of colors of inks comprising an oil-based ink containing a dye lake pigment and an oil-based ink containing a pigment other than dye lake pigments, and superposing the plurality of colors of inks when printing, the oil-based ink containing a dye lake pigment is ejected on a printing medium prior to the oil-based ink containing a pigment other than dye lake pigments.

摘要： An ink cartridge contains an outer package, an ink container within the outer package, and sheet bodies attached to an outer surface of the outer package, and is attachable to and detachable from a printing device. Small pieces are formed by cuts in the outer package. The small pieces include breakable sections, and the bendable sections. Sheet bodies cover a portion of the small pieces. Pressing on a small piece with a finger breaks the breakable section, and bends the bendable section to press them inside the outer package. A portion of the sheet body then shifts upwards so that the sheet body can be grasped with fingers and peeled away from the outer package. Disassembly and sorting of used cartridges in this way becomes easier.

摘要： An image processing apparatus performs operations including: when a density value of a black component in uncorrected monochrome image data corresponding to each of pure colors including primary colors and secondary colors in color image data is lower than a reference density value, the uncorrected monochrome image data being obtained by a monochrome conversion from the color image data to monochrome image data, determining a correction content for correcting the density value of the black component in the uncorrected monochrome image data corresponding to at least each of the pure colors out of the pure colors and peripheral colors of the pure colors in a color space to a value equal to or higher than the reference density value; and obtaining corrected monochrome image data in which correction based on the determined correction content is reflected in the uncorrected monochrome image data.

摘要： A controller of an inkjet printer performs control to: during ink delivery in a first ink tank pair, as a preparation of ink delivery in a second ink tank pair, generate positive pressure and negative pressure respectively in third and fourth ink tanks of the second ink tank pair and supply ink to the second ink tank pair; and upon completion of the ink delivery in the first ink tank pair, perform printing by ejecting the ink from an inkjet head while delivering the ink between the third and fourth ink tanks of the second ink tank pair prepared for the ink delivery via an ink flow passage and the inkjet head.

摘要： A sheet feed device includes a removal sheet feed tray, a bottom plate provided in the sheet feed tray, and can be lifted up together with one or more papers stacked thereon so as to make an uppermost paper positioned at an upper limit position, a sheet feeder that feeds out the papers stacked on the bottom plate sequentially from the sheet feed tray, a sheet detection member that detects whether or not at least one paper is stacked on the sheet feed tray, an upper limit detection member that detects whether or not the uppermost paper is positioned at the upper limit position, and an evacuator that evacuates the sheet detection member and the upper limit detection member to an evacuation position where the sheet detection member and the upper limit detection member never interfere a removal and an installation of the sheet feed tray.

摘要： An image processing method comprising: converting an RGB input signal to a CMYK signal; converting the RGB input signal to a common color signal including lightness; generating a first Gray signal including a Gray value substituted for CMY values forming gray in the CMYK signal; generating a second Gray signal including a Gray value corresponding to a K value greater than a threshold in the CMYK signal; generating a Gray output signal in a CMYKGray output signal indicating color material amounts of cyan (C), magenta (M), yellow (Y), black (K), and gray (Gray) for printing by multiplying the generated first Gray signal and the generated second Gray signal respectively by coefficients corresponding to the lightness in the common color signal and then synthesizing the first Gray signal and the second Gray signal.

摘要： The method is a non-aqueous inkjet printing method including the steps of: ejecting droplets of a non-aqueous pigment ink containing at least a pigment and a non-aqueous solvent onto a surface of a printing medium to form dots composed of the non-aqueous pigment ink, and then ejecting droplets of a non-aqueous post-treatment liquid containing at least silica and an organic solvent toward the printing medium so that the droplets overlap with the dots composed of the non-aqueous pigment ink, wherein either of the non-aqueous pigment ink and the post-treatment liquid contains a water-soluble resin having an amino group.
