    摘要: Method of generating a copy detection pattern (CDP), or a portion of a CDP, for printing on a substrate, comprising: generating a plurality of digital files, each of an image comprising an at least partially random two dimensional (2D) distribution of dark and light pixels, and applying an optimization process configured to increase a copy detection performance of a resultant digital file output by the method, said optimization process comprising a) comparing a copy detection performance of a first of said plurality of digital files, which constitutes a test digital file, with a copy detection performance of another of said plurality of digital files modified with respect to said test digital file, which constitutes a modified digital file, b) replacing the test digital file with said modified digital file, if the copy detection performance of said modified digital file is greater than the copy detection performance of the test digital file, in which case the modified digital file becomes the test digital file, and c) repeating steps a) and b) until a termination condition is met.

    摘要: A sheet conveyance device has a sheet conveyance path with a first path and a second path. A wireless tag communication device can write information to a wireless tag on a sheet on the first and second paths and receive responses from the wireless tag. A controller controls the wireless tag communication device to attempt to write information to the wireless tag while on the first path, then determines whether information has been written to the wireless tag on the first path according to a response received from the wireless tag. The controller switches a conveyance destination for the sheet to the second path if the information has not been written or to a discharge location if the information has been written. The controller then controls the wireless tag communication device to attempt to write information to the wireless tag while the sheet is on the second path.
