  • Patent number: 10885405
    Abstract: A method for correcting cross-track position errors in a digital printing system having a linear printhead includes printing a test target including a plurality of alignment marks. A data processing system is used to automatically analyze a captured image of the printed test target to determine a measured position for each of the alignment marks. The measured positions for the alignment marks is compared to reference positions to determine measured cross-track position errors. A cross-track position correction function is determined responsive to the measured position errors, wherein the cross-track position correction function specifies cross-track position corrections to be applied as a function of cross-track position. A corrected digital image is determined by resampling the image lines of a digital image responsive to the cross-track position correction function.

  • Patent number: 10872278
    Abstract: A method for correcting tone-level non-uniformities in a digital printing system includes printing a test target having a set of uniform test patches. The printed test target is automatically analyzed to determine tone-level errors as a function of cross-track position for each of the test patches. A tone-level correction function is determined and represented using a set of one-dimensional feature vectors which specifies tone-level corrections as a function of cross-track position and pixel value. Corrected image data is determined by using the tone-level correction function to determine a tone-level correction value for each image pixel responsive to the input pixel value and cross-track position of the image pixel. The corrected image data is printed using the digital printing system to provide a printed image with reduced tone-level errors.

  • Patent number: 10847887
    Abstract: A transparent antenna is fabricated by printing a pattern of catalytic ink onto a web of substrate in one or more conductive regions, wherein a geometry of the conductive regions defines an antenna pattern. A pattern of non-conductive ink is printed in registration onto the substrate in a fill pattern, wherein the fill pattern is an inverse of the antenna pattern within a defined region of interest. A conductive material is electrolessly plated onto the pattern of catalytic ink by transporting the web of substrate through a reservoir of plating solution to provide a corresponding pattern of conductive material, thereby providing the transparent antenna. An average optical transparency in the conductive regions and non-conductive regions is at least 50%, and the average optical transparency in the conductive regions differs from that of the non-conductive regions by no more than 10%.
