Abstract: A printing device and method for printing a latex ink on a printing medium is disclosed. The printing device comprises a heating stage for heating the medium at least during printing the latex ink on said medium, a further heating stage for curing the latex ink on the medium and a controller arrangement for individually controlling the heating stage and the further heating stage, whereby the controller arrangement is arranged to reduce the heat output of the heating stage during a non-printing mode of the printing device and to reduce the heat output of the further heating stage during a non-curing mode of the printing device.

Abstract: A printing apparatus is provided which uses, as a print head, a thermal head having heating elements arrayed in a line perpendicular to the traveling direction of a printing medium. Correspondingly pixel data, at either end, or near the end, of each line of image data going to be printed, data on heat storage in the thermal head (108) is calculated for each line on the basis of data on heat storage in the print head for a preceding line, and the data on heat storage in the print head for each line is compared with predetermined-temperature data. When any of the stored-heat data is larger than the predetermined-temperature data, energy to the heating element (113) is decreased. The image data is printed on the printing medium (104) with the energy for application to the heating element (113) being kept decreased.

Abstract: A thermal activation device has a thermal activation head that thermally activates a heat-sensitive adhesive layer of a sheet material having a printing layer on one surface of a sheet-like base material and the heat-sensitive adhesive layer formed on the other surface thereof. A platen roller conveys the sheet material and is disposed in pressure contact with the thermal activation head so that the platen roller and the thermal activation head apply a holding force on the sheet material. A pair of conveyor rollers hold and convey the sheet material and are disposed on a downstream side of the thermal activation head in a conveying direction of the sheet material. A holding force applied on the sheet material by the pair of conveyor rollers being larger than a holding force applied on the sheet material by the platen roller and the thermal activation head.

Abstract: A printer that applies donor material from donor patches on a donor web to a receiver medium using a thermal printhead that generates heat and a method for operating such a printer are provided. The method comprises the steps of: receiving a print order requesting the printing of a quantity of images; determining a temperature of the printhead; printing a designated number of the quantity of the images in a sequence; determining a length of time of a programmed delay; delaying the printing for the determined length of time of the programmed delay; and printing remaining images from the quantity of images. The length of each programmed delay is determined by using the temperature of the printhead and a time rate of cooling of the printhead and, is determined in a manner that provides a sufficient cooling time to prevent the printhead from reaching a maximum printhead temperature during printing.

Abstract: A printer has a sheet housing unit for storing a heat-sensitive adhesive sheet having a heat-sensitive adhesive layer on one side and a printable surface on the other side. A set of pull-out rollers pulls the heat-sensitive adhesive sheet out of the sheet housing unit and transports the sheet in a given direction, and a cutter device cuts the heat-sensitive adhesive sheet that has been transported by the pull-out rollers. A printing device has a thermal print head for printing letters or images on the printable surface of the heat-sensitive adhesive sheet, and a print platen roller for transporting the heat-sensitive adhesive sheet in the given direction. A thermal activation device has a thermal-activation thermal head for heating the heat-sensitive adhesive layer, and a thermal activation platen roller for transporting the heat-sensitive adhesive sheet in the given direction. A first drive unit drives the pull-out rollers and a second drive unit drives the print platen roller.

Abstract: Print data containing a specific print pattern and the number of paper sheets to be printed is input from an external interface. On the basis of the print pattern and the number of printing thereof to be printed, the temperature of an inkjet printhead is predicted by a program executed by a CPU. A drive signal for the inkjet printhead is set before the start of printing on the basis of the prediction result.

Abstract: There is disclosed a data processing method for correcting heating data for a thermal head of a thermal printer, to eliminate influence of heat energy accumulated in first to Nth heat accumulating layers of the thermal head. Basic heating data of a subject line is corrected with first to Nth correction data obtained by multiplying first to Nth heat accumulation data by predetermined coefficients respectively. The heating elements are driven in accordance with the corrected heating data, to print the subject line. A drive voltage to be applied across heating elements of the thermal head is determined at the start of printing a frame of image, according to an environmental temperature around the thermal head and a head temperature measured through a thermistor mounted in the Nth heat accumulating layer of the thermal head. The Nth coefficient is calculated according to a formula that includes the head drive voltage as a parameter.
