  • Patent number: 10249520
    Abstract: Embodiments of the invention pertain to methods useful in transfer printing of small objects, like micro-LEDs from one substrate to another using acoustic or ultrasonic energy. The pickup of objects from a substrate is performed by transfer head equipped with sticky polymer and an array of ultrasonic transducers, and the high efficiency and selectivity of pickup of selected objects is done using ultrasonic energy directed towards the object. The disposing of objects to another substrate from a transfer head is done by directing an ultrasonic energy toward an object, which enable effective and selective detachment of an object from a sticky polymer. Yet another embodiment also uses a UV light source, which directs the light to the UV curable liquid disposed around the object on receiving substrate, thus curing this liquid would attach an object to receiving substrate.

  • Patent number: 9984145
    Abstract: The present disclosure relates to a system for verifying homogeneity in clusters and comprises a processor and a non-transitory computer readable memory storing instructions that are executable by the processor. The system creates at least one adjacency matrix representing a relationship between rows and columns of a table. The system applies an algorithm to the table to identify a first set of clusters. For each identified cluster, the system compares a computed dispersion value to a predetermined threshold. The cluster is associated as being homogeneous if the threshold is not met and not homogeneous if the threshold is met. The system reapplies the algorithm to the set of non-homogenous clusters within the data set and repeats the thresholding processes until each cluster resulting from the data set is homogeneous. Upon reaching the desired homogeneity for each cluster, the system recombines the clusters sequentially while keeping the each identified cluster together.

  • Patent number: 9561645
    Abstract: Provided is an image-forming apparatus that limits reductions in image quality such as streaking even when print element discharge failure occurs in the overlap region of short heads that configure a long head. In the overlap region, among multiple overlap areas configured from rows of consecutive print elements that do not comprise print elements that have been specified as discharge failure print elements, the overlap area with the largest number of overlapping print elements is specified. When the number of print elements in said overlap area is greater than a fixed number, an overlap control for gradually changing the discharge apportionment for the fixed number of print elements in each short head is performed. Since the discharge failure of the print element is present in an area in which the short head print apportionment is 100%, the discharge failure is supplemented by, for example, increasing the discharge amounts of the adjacent print elements.

Then, such devices and methods count the fractional remaining distance in velocity-based distance increments at regular time intervals using the time counter. When the time counter reaches the last velocity-based distance increment of the fractional remaining distance, these devices and methods transfer the marking material from the printhead to the substrate.

  • Patent number: 9090086
    Abstract: In an overlapping head including a plurality of recording head chips overlapped to each other, a color shift can occur between a color recorded by an overlapping region and a color recorded by a non-overlapping region, which cannot be corrected by a density correction using head shading or the like. To correct such a color shift, a test pattern is recorded by the overlapping region and the non-overlapping region and colors of the recorded test pattern are measured. Color correction data to be used in correction of colors of an image to be recorded is generated based on a result of the measurement of the colors.

  • Patent number: 9044947
    Abstract: An object of the present invention is to provide an ink jet printing apparatus which can prevent possible stripe-like density unevenness in a joint in a print head constructed by joining a plurality of chips together even if the print head is inclined to the regular position of the print head. The present invention uses a print head having the nozzle arrays being shifted in a direction in which the nozzles are arranged, so as to have overlapping portions in a direction orthogonal to the nozzle arranging direction. The present invention controls an ink ejecting operation of the nozzles in the overlapping portions between the plurality of nozzle arrays on the basis of an angle between the nozzle array arranging direction and a direction orthogonal to the direction in which the print head moves relative to the print medium.

  • Patent number: 8998359
    Abstract: Disclosed are a multicolor overprint control method and device applicable to an intermittent printing apparatus. According to the operating characteristic of the intermittent printing apparatus, the method solves the problems of overlap and inaccurate overprint of various colors during intermittent printing by controlling the relationship between the distance between adjacent color group modules of different colors and the motion distance between uniform segments of the intermittent printing apparatus. In addition, the method also sets different inkjet printing modes in accordance with whether the detected inkjet printing of the same color group module is in a first period, thereby solving the problems of printing media waste and discontinuous printing data. The method achieves multicolor digital inkjet printing by combining the unique motion mode of the printing media thereof, and makes printing contents flexible and changeable on the basis of guaranteeing printing efficiency.
