Abstract: A color test pattern comprising color patches can be printed together with an image (text and/or a pictures, for example) of a print job. After printing, reflections, known as flare, from the image may adversely affect measurements taken of the color patches. To help reduce the effects of flare, a determination is made prior to printing as to the layout of the color patches. The determination involves comparing the color properties of the color patches with those of the image.

Abstract: A print management method implemented in a system including a client computer, a server, and a plurality of printers is disclosed, which includes by the server: (a) receiving, from a client computer, a request relating to a print job; (b) determining whether a predetermined print quality is required for the print job; (c) filtering at least two printers each of which has an in-line spectrophotometer from the plurality of printers; (d) instructing the each filtered at least two printers to conduct a color validation process by using the in-line spectrophotometer; (e) receiving, from the each filtered at least two printers, a result corresponding to the color validation process by the in-line spectrophotometer; and (f) determining at least one candidate of a destination printer for the print job based on whether the each filtered at least two printers meets predetermined print quality, using the result corresponding to the color validation process.

Abstract: An RFID tag having an initial range may be modified to have a reduced or increased range by printing a modification element over the antenna of the RFID tag. The modification element may function as an extension of the antenna or may function to shield the antenna. To allow for cost-efficient modification of RFID tags, multiple RFID tags may be secured on a substrate and modified together.

Abstract: RFID tags are combined in increase their range. A first RFID tag comprises a first chip and a first antenna configured to transmit data from the chip. The first RFID tag has a first initial range by which data may be obtained by an RFID reader from the first chip. A second RFID tag comprises a second chip and a second antenna configured to transmit data from the chip. The second RFID tag has a second initial range by which data may be obtained by an RFID reader from the second chip. A conductive path from first antenna to the second antenna is established to change initial ranges to modified ranges which are greater than the initial ranges.

Abstract: An image forming apparatus, a method, and a computer readable medium are disclosed for generating color patches for color validation of a print engine of an image forming apparatus. The method includes acquiring a validation result on a first color validation chart with a sensing device, the sensing device configured to read a color validation chart, the color validation chart having one or more color patches, and wherein the validation result compares a color accuracy of each of the one or more color patches from the first color validation chart to a target color; and determining an order of each of the color patches in a second color validation chart to be printed based on the validation result on the first color validation chart, wherein the order of the color patches in the second color validation chart is determined based on color patches that do not match the target color.

Abstract: Tamper detection on an article is performed by reading data from an RFID tag having an antenna with segments designed to break apart. The RFID tag is secured to the article in such a way that, when the article is tampered with, the antenna segments will break apart. Detachment would decrease the reading range of the RFID tag. An RFID reader may be used to read the data from the RFID tag. The predefined reading range (Rp) of the RFID tag, with antenna segments entact, is obtained from the data which was read by the RFID reader. The RFID reader obtains the data while located at an actual reading range (Ra) relative to the RFID tag. By comparing Ra with Rp, it is determined whether the antenna is still entact. If Ra

Abstract: Print shop operations may be visualized graphically to show relationships between a stream of incoming print jobs and a group of available print production devices, such as printing and finishing machines. A visualization process is performed with microservices to generate UI device panes, which form elements of a graphic user interface from which print shop operation can be monitored or controlled. Each microservice corresponds a different one of the print production devices. This can allow for rapid adjustments and customization of the UI, as may be needed due to user feedback, change in user requirements, and introduction of new print production devices to the print shop. Information may be added to the graphic user interface in combination with the UI device panes to facilitate assignment of print jobs to particular print production devices and/or to show which devices can be used sequentially or in parallel to complete the print jobs.

Abstract: An image forming apparatus, a method and a computer readable medium for color verification of an image forming apparatus are disclosed. The image forming apparatus includes a sensing device configured to read a color chart; and a processor configured to: perform a first color verification job; perform a second color verification job after the first color verification job when the first color verification job is interrupted, the second color verification job including one or more color patches from a previous color verification job; acquire measurement data from the previous color verification job; acquire measurement data from the second color verification job; and determine whether to re-use the measurement data of the previous color verification job based on one or more differences between the measurement data of the previous color verification job and the measurement data of the second color verification job.

Abstract: A method, a system, and a non-transitory computer readable recording medium are disclosed for a first printer connected to a second printer to perform color calibration for the second printer, wherein the second printer does not have a sensor, the first printer including a sensor which measures a media, which has been printed by the second printer and is being fed on a media path of the first printer. The method includes (a) determining the timing to instruct the second printer to print a first measurement chart; (b) instructing, at the timing determined at step (a), the second printer to print the first measurement chart; (c) measuring, by the sensor, the first measurement chart which has been printed by the second printer; and (d) outputting information corresponding to a result measured at step (c).
