RISO KAGAKU CORPORATION

A printing apparatus includes: a gloss forming unit that forms at least two regions having different gloss levels on a print medium; and a print image forming unit that forms a print image on the at least two regions having different gloss levels of the print medium after the gloss forming unit forms the at least two regions.

A sheet feeding apparatus, includes: a loading table on which a plurality of sheets are loaded; a flotation air supply unit that causes the sheets to float by supplying air toward the edge surfaces of the plurality of sheets which are loaded on the loading table; a suction conveying unit that suctions and conveys the topmost sheet among the plurality of sheets which are caused to float by the supply of air; an image capturing unit that captures an image of a flotation state of the plurality of sheets which are caused to float by the supply of air; a control parameter adjusting unit that adjusts control parameters of the flotation air supply unit based on information on the flotation state obtained from the image captured by the image capturing unit; and a control unit that controls the flotation air supply unit based on the control parameters.

A medium feeding device includes a feeder that feeds a medium, a medium detection sensor that detects the medium fed by the feeder, and a processor that changes feed settings of the feeder based on a detection result of the medium detection sensor, wherein the processor switches a feed setting to be changed among a plurality of the feed settings of the feeder based on the detection result of the medium detection sensor.

A transfer medium producing apparatus is equipped with an ink ejection unit 20 that ejects ink onto a peelable sheet, an adhesive solution application unit 30 that applies an adhesive solution onto the peelable sheet onto which the ink has been ejected, and a control unit 2 that controls the ejection of ink and the application of the adhesive solution to be performed by a wet on wet method.

A textile printing apparatus includes a base forming ink head that discharges a base forming ink onto a base material to which a pretreatment liquid has been applied, a leveler that levels the base forming ink discharged on the base material, and an image forming ink head that discharges an image forming ink onto the base material on which the base forming ink has been leveled.

An image processing apparatus includes a processor being configured to extract characteristic information of a printed material corresponding to a base material used for printing using pretreatment liquid, base ink, and color ink and a printing condition of the printing, and to generate a characteristic information image representing the extracted characteristic information.

A sheet feed device includes: a conveyor configured to convey a top sheet of sheets floated from a sheet stack; a blower configured to blow air in an obliquely upward direction from a position lower than the conveyor toward the sheet stack; and a direction converter configured to convert a direction of the air blown by the blower to a direction which is downward more than a direction of the air at a position where the air is blown from the blower and let the air flow in between the top sheet and a second sheet subsequent to the top sheet of the sheets floated from the sheet stack.

A paper supply device is equipped with a paper supply unit that sequentially supplies a plurality of print media, and a control unit that controls the paper supply unit. During sequential supply of a plurality of print media at a paper supply interval, in the case that it is necessary to secure a paper supply interval which is set in advance and is longer than the paper supply interval, a reference paper supply interval, based on a point in time which is a natural number multiple of the paper supply interval, and a post print process paper supply interval are compared. Print media are supplied at the post print process paper supply interval in the case that the post print process paper supply interval and the reference paper supply interval are different.

A transfer medium producing apparatus is equipped with an ink ejection unit 20 that ejects ink onto a peelable sheet, an adhesive solution application unit 30 that applies an adhesive solution onto the peelable sheet onto which the ink has been ejected, and a control unit 2 that controls the ejection of ink and the application of the adhesive solution to be performed by a wet on wet method.

A discharge tray for loading thereon sheets to be discharged at a predetermined discharge angle by a discharge roller pair is provided. The discharge tray includes a loading surface provided at a predetermined first inclination angle with respect to a discharge direction of a sheet by the discharge roller pair so that a top of the sheet discharged by the discharge roller pair comes into contact with the loading surface, and a guide unit provided on the loading surface at a second inclination angle with respect to the loading surface so as to partially lift up the loaded sheet from the loading surface.
