Publication number: 20230173825Abstract: A device (1) is for guiding printer (20). The device (1) is utilized in a method for using a handheld electronic printer (20) with the device (1). The device (1) includes a base (2) having at least one guide (5), and a carriage (3) having at least two separate links (26, 27) engaged with the at least one guide (5). The at least one guide (5) has at least two linear sections (7, 8) being spaced apart and parallel. The at least one guide (5) includes at least two changeover sections (10, 11), each connecting two linear sections (7, 8). The changeover sections (10, 11) are arranged at different positions of the linear sections (7, 8) the changeover sections respectively connect.Type: ApplicationFiled: May 14, 2021Publication date: June 8, 2023Applicant: COLOP Digital GmbHInventor: Cedric HEINL

Publication number: 20220414199Abstract: A method and token (3) for corroborating a document (25) includes having a registered token (3) with a token identity. The token (3) is able to print visual markings. A document identifier is obtained (18) based on at least the token identity and a timestamp. The document identifier is encoded (19) into a visual marking (24), and the visual marking (24) is applied to the document (25). A copy of the document (25) is obtained (27) with or without the visual marking (24), and copy is stored in association with the document identifier. The token (3) includes storage holding a token identity and a printing unit. The token (3) is configured to receive the visual marking (24) encoding a document identifier associated with the token identity and to print the received visual marking (24). A method also verifies a document (41) having a corresponding visual marking (42).Type: ApplicationFiled: November 4, 2020Publication date: December 29, 2022Applicant: COLOP Digital GmbHInventor: Alex BRETON

Patent number: 11430234Abstract: A method of authentication using surface paper texture includes steps of capturing a topographic pattern image of a surface of a region of interest of the paper artifact and extracting a plurality of specific features from the captured topographic pattern image. The method further identifies the location of the specific features of the paper artifact from the captured topographic pattern image. A bit map of the identified location of the specific features is generated. Then, a reference image of a reference bit map printed on the region of interest of the paper artifact is captured. Finally, the method compares the generated bit map with the captured reference bit map to generate a score. The score of the comparison determines the level of authentication. The method provides an offline method of authentication.Type: GrantFiled: January 6, 2020Date of Patent: August 30, 2022Assignee: COLOP Digital GmbHInventors: Johan Bergqvist, Erik Bohlin, Nikolaus Frank

Patent number: 11225087Abstract: A method of controlling a hand-operated printer (3) includes detecting a transverse movement of the hand-operated printer (3) after finishing a first swath (1). The method compares a transverse distance covered by the transverse movement with a predetermined transverse distance (11) between said first swath (1) and a second swath (2). A transverse-stop signal is emitted when the transverse distance covered by the transverse movement reaches the predetermined transverse distance (11).Type: GrantFiled: June 25, 2019Date of Patent: January 18, 2022Assignee: COLOP Digital GmbHInventor: Alex Breton

Publication number: 20210271292Abstract: A docking station (1) is for an electronic hand stamp having an inkjet printhead. The docking station (1) includes a body (2) having a rest surface (4) for receiving a substantially flat bottom side of an electronic hand stamp and a border (5) at least partially framing the rest surface (4). The docking station (1) also includes at least one wiper element (3) connected to the body (2) and that projects on one side from the body (2). The wiper element (3) includes a wiper blade (17) for manually sweeping across an inkjet printhead.Type: ApplicationFiled: June 25, 2019Publication date: September 2, 2021Applicant: COLOP Digital GmbHInventors: Alex BRETON, Franz VĂ–LKL

Publication number: 20210122176Abstract: The electronic hand stamp (1) includes an inkjet printhead with nozzles directed toward a bottom side (4) of the electronic hand stamp (1), a control circuit (30) and a motion detector. The control circuit (30) is connected to the motion detector and to the inkjet printhead and configured to control the inkjet printhead in response to readings received from the motion detector. The electronic hand stamp (1) includes at least four indicator LEDs (10-17) connected to the control circuit (30). At least one of the at least four indicator LEDs (10-17) is arranged on every side perpendicular to the bottom side (4) of the electronic hand stamp (1).Type: ApplicationFiled: June 25, 2019Publication date: April 29, 2021Applicant: COLOP Digital GmbHInventor: Alex BRETON

Publication number: 20200083954Abstract: Method to authenticate a substrate based on unique microstructure inherent to a region of interest of a substrate surface of the substrate, comprising the steps: (a) emitting photons from a light source onto the region of interest; (b) emitting ultrasound waves from a ultrasound source onto the region of interest; (c) capturing at least one image of the region of interest in one or both of the following two ways: (i) capturing a light image in the presence of ultrasound to obtain at least one captured image of the region of interest, or (ii) capturing an ultrasound echo image in the presence of IR or near IR light to obtain at least one captured image of the region of interest; and (d) comparing the at least one captured image with at least one reference in order to determine authenticity of the substrate.Type: ApplicationFiled: May 16, 2017Publication date: March 12, 2020Applicant: COLOP Digital GmbHInventor: Johan BERGQVIST
