摘要： A method, apparatus, and computer program product are described herein for controlling a printing device. In an example embodiment, a print line is divided into frames and frame dot states are determined based on neighboring frame dot states. Maximum motor speeds of the printing device may be adjusted so that actual motor speeds change gradually during printing. The print engine may detect a printhead type by sending a signal to the printhead and receiving a response.

摘要： Techniques are disclosed herein for estimating parameters of a model of a thermal print head for use in performing thermal history control. In particular, techniques are disclosed for use in conjunction with a thermal print head having a plurality of print head elements and an associated heat sink. A sensitivity of a thermal print media to a temperature of the heat sink is identified. A sensitivity of the thermal print medium to a temperature of the plurality of print head elements is then identified based on the identified sensitivity of the thermal print medium to the temperature of the heat sink. Techniques are also disclosed for deriving conditions on estimated parameters of the print head model that determine the stability of the resulting thermal history control algorithm. Techniques are also disclosed for iteratively optimizing the values of those parameters.

摘要： A model of a thermal print head is provided that models the thermal response of thermal print head elements to the provision of energy to the print head elements over time. The thermal print head model generates predictions of the temperature of each of the thermal print head elements at the beginning of each print head cycle based on: (1) the current ambient temperature of the thermal print head, (2) the thermal history of the print head, and (3) the energy history of the print head. The amount of energy to provide to each of the print head elements during a print head cycle to produce a spot having the desired density is calculated based on: (1) the desired density to be produced by the print head element during the print head cycle, and (2) the predicted temperature of the print head element at the beginning of the print head cycle.

摘要： Techniques are disclosed for performing thermal history control in a thermal printer in which a single thermal print head prints sequentially on multiple colorforming layers in a single pass. Each pixel-printing interval may be divided into subintervals, which may be of unequal duration. Each sub-interval may be used to print a different color. The manner in which the input energy to be provided to each print head element is selected may be varied for each of the subintervals. For example, although a single thermal model may be used to predict the temperature of the print head elements in each of the subintervals, different parameters may be used in the different subintervals. Similarly, different energy computation functions may be used to compute the energy to be provided to the print head in each of the subintervals based on the predicted print head temperature.

摘要： In order to carry out histogram control so that colors of regions printed for overlapping regions are appropriate for a multi-color, multi-stencil thermal silkscreen stencil-making device, a hue, printing density and corresponding extracted color for ink used in multi-color, multi-stencil printing are inputted, of which a color of the densest printing density is set at a color separation circuit 36 as an extracted color for making a histogram. A histogram producing circuit 34 constituting a histogram controller 33 is then initialized, histogram data HD for the color extracted for making a histogram is acquired while reading an original, and this histogram data HD is temporarily stored in memory 37. While stencils are being made for all of the colors, the stencils are made while an energy control circuit 35 carries out histogram control based on an applied energy control signal S corresponding to histogram data HD stored in the memory 37 and binary data D3.
