Publication number: 20240129425Abstract: A color printing system manages ICC profiles by controlling ink use without performing the ICC profile creation operations. To obtain an ink limit for an ICC profile, a table associated with the ICC profile is parsed to determine the ink limit. The ink limit is decreased or increased. For an ink limit decrease, a color over the decreased ink limit is adjusted to meet the new ink limit. The ICC profile is updated accordingly. For an ink limit increase, the combination of primary colors are boosted by a percentage amount. Checks are made with regard to the volume-based ink limit and an quality check operation to accepted the boosted amount. The ICC profile is updated accordingly.Type: ApplicationFiled: December 22, 2023Publication date: April 18, 2024Applicant: Kyocera Document Solutions Inc.Inventors: Michael M. CHANG, Javier A.

Patent number: 11914780Abstract: A finger-mounted device may include finger-mounted units. The finger-mounted units may each have a body that serves as a support structure for components such as force sensors, accelerometers, and other sensors and for haptic output devices. The body may have sidewall portions coupled by a portion that rests adjacent to a user's fingernail. The body may be formed from deformable material such as metal or may be formed from adjustable structures such as sliding body portions that are coupled to each other using magnetic attraction, springs, or other structures. The body of each finger-mounted unit may have a U-shaped cross-sectional profile that leaves the finger pad of each finger exposed when the body is coupled to a fingertip of a user's finger. Control circuitry may gather finger press input, lateral finger movement input, and finger tap input using the sensors and may provide haptic output using the haptic output device.Type: GrantFiled: August 11, 2022Date of Patent: February 27, 2024Assignee: Apple Inc.Inventors: Paul X Wang, Alex J.

Patent number: 11769025Abstract: A color printing system includes a printing device and other components that use color printing resources, such as calibration and ICC profiles, to complete color printing operations. These color printing resources are used for a large number of paper types stored in a paper catalog. The paper types can be further placed into paper groups within the paper catalog. The paper groups may be formed by assigning new papers into the paper catalog to those having paper types with existing calibration data and ICC profiles. These relationships are shown in a paper catalog map. The print shop can use the paper catalog map for selling paper types, providing different capabilities for paper types, and other information.Type: GrantFiled: September 9, 2021Date of Patent: September 26, 2023Assignee: Kyocera Document Solutions Inc.Inventors: Michael M.

Patent number: 11283966Abstract: Example embodiments relate to dynamic sharing of ICC profiles. A computing device may receive data representing a paper type, a customer precision requirement, and supporting parameters and perform a search of a paper catalog using the data for an existing ICC profile that satisfies the customer precision requirement. Search parameters used during the search of the paper catalog may depend on a level of the customer precision requirement. Responsive to identifying an ICC profile during the search of the paper catalog that satisfies the customer precision requirement and can be used by the printer make and model associated with the original request, the computing device may transmit the ICC profile to the requesting printer via a network. In some instances, the computing device may determine the paper catalog lacks an ICC profile that satisfies the customer precision requirement and transmit an indication that no existing ICC profile is available.Type: GrantFiled: August 25, 2020Date of Patent: March 22, 2022Assignee: KYOCERA Document Solutions Inc.Inventor: Michael M.

Patent number: 11265445Abstract: Color conversion attempt to reproduce an input CMYK combination on a print media using an output CMYK combination. In a 2-step process, ICC profiles are used for the color conversion. In some instances, a 1-step process may be used that avoids the use of the ICC profiles and provides a faster processing time. A color progression checker determines whether the 1-step process may be used for color conversions based on standard deviations of the colorants along paths within a three-dimensional look-up table for a destination ICC profile. If a certain number of standard deviations exceed 20%, then the 1-step process for color conversion may not be effective.Type: GrantFiled: June 3, 2021Date of Patent: March 1, 2022Assignee: Kyocera Document Solutions Inc.Inventor: Michael M.

Patent number: 11182112Abstract: Example embodiments relate to creating ICC printer profiles with unorthodox ink limits. A printing device may initially print a color profile chart represented by color combinations that are equal to or below an ink limit and generate a first ICC profile based on the color profile chart. The first ICC profile uses a first color set to map input colors of a source color space to output colors of a destination color space. At least one color of the first color set, however, may be represented by a color combination that exceeds the ink limit and thus the printing device may determine a second color set based on the first color set. For the second color set, each color is represented by a color combination that is equal to or below the ink limit. A second ICC profile may be generated to use the second color set.Type: GrantFiled: June 29, 2020Date of Patent: November 23, 2021Assignee: KYOCERA Document Solutions Inc.Inventors: Michael M. Chang, Javier A. Morales
