Abstract: Access is provided to a variable data printing app and a code detection app on a computer server. The variable data printing app is adapted to add machine-readable code to printable items and create a decoder app capable of decoding the machine-readable code. The code detection app is adapted to receive user identification information and transmit the user identification information to designer devices. The printable items are printed as printed products. The designer devices validate a user device based on the validity of the user identification information. In response, the variable data printing app is adapted to transmit the decoder app to validated user devices. The code detection app, operating on the user device, is adapted to decode the machine-readable code in user-acquired images into an optional secure link with the designer devices.

Abstract: An image system for detecting defects in an image may include a processing device to detect defects in a target image by analyzing the activity level in a reference and the target image. The system may identify a quiet area/pixel in the reference image based on the activity level, check the activity level of the corresponding pixel in the target image, and classify the pixel in the target image as defective if the activity level of the pixel in the target image exceeds a noise threshold. The system may additionally swap the reference and target image, repeat the detection steps and combine the detection results with those before the swap. The system may also include an image sensor to scan a printed document of the reference image into a scanned electronic document (the target image).

Abstract: Methods and systems for creating a security mark for a document. A first generation print can be rendered based on one or more patterns (e.g., pantograph pattern) for a security mark. Post-copy results of the pattern(s) can be then rendered. The first generation print and the post-copy results of the pattern(s) can be calibrated, and the output of the calibration of the first generation print and the post-copy results are then applicable for optimizing the design of the security mark for a print condition. Optimization of the design of the security mark for the print condition can be implemented by applying the output of the calibrating of the first generation print and the post-copy results for the print condition. The first generation prints and post-copy results of pantograph pattern samples can be calibrated to drastically reduce the time and labor involved in optimizing void pantograph designs for a particular print condition.

Abstract: Methods, apparatuses, devices, and systems are disclosed herein for upscaling an input image to a higher resolution while simultaneously converting the image data from a multi-drop state to a binary state. These systems and methods use a probabilistic combination of randomized and biased positioning of inkjet firings in order to yield perceptibly lower graininess in low-coverage areas of output prints without introducing new artefacts.

Abstract: A system for detecting defects in a print system may include a print engine to print an electronic document (a reference image) and yield a printed document. The system may also include an image sensor to scan the printed document into a scanned electronic document (a target image). The system may include a processing device to detect defects in the printed document by analyzing the activity level in the reference and target image. The system may identify a quiet area/pixel in the reference image based on the activity level, check the activity level of the corresponding pixel in the target image, and classify the pixel in the target image as defective if the activity level of the pixel in the target image exceeds a noise threshold. The system may additionally swap the reference and target image, repeat the detection steps and combine the detection results with those before the swap.

Abstract: An image has pixels arranged in perpendicular rows/columns. The size of the image is changed to produce a changed-size image and the changed-size image is output. The process of changing the size of the image adds at least one row/column as at least one inserted row/column. The inserted row/column is made up of data from generating adjacent rows/columns of the perpendicular rows/columns. Embodiments that reduce the size of the image remove the generating adjacent rows/columns that were used to form the inserted row/column and, in such reduction processing the inserted row/column is added where the (now removed) generating adjacent rows/columns were previously positioned. In embodiments that increase the size of the image, instead of removing the generating adjacent rows/columns, the inserted row/column is merely inserted between the adjacent rows/columns.
