  • Patent number: 11141989
    Abstract: An electrohydrodynamic (EHD) jet printing apparatus or system may include circulation of printing fluid to minimize or eliminate clogging in a nozzle. An exemplary nozzle comprises at least two ink channels—one allowing flow to a droplet emitting opening and one allowing flow away from the droplet emitting opening—configured for circulating ink. The nozzle may transfer ink to a substrate with an EHD technique involving voltage or current modulation. For example, an electric field may be applied between the nozzle and printing substrate such that the ink meniscus changes shape and releases ink from the tip of the liquid cone. A multi-channel nozzle may take a variety of configurations, including two co-axially aligned capillaries, side-by-side parallel capillaries, or capillaries arranged at an angle with respect to one another but converging at a single point where the conical meniscus is formed.

  • Patent number: 11124005
    Abstract: With a conventional method of estimating an application amount of a clear recording material from a color of a patch, it is difficult to realize high accuracy, similar colors are sometimes exhibited in measurement results even if there is a significant difference in the application amount of a clear ink. In contrast, with a disclosed configuration of estimating an application amount of a clear recording material from a reflection intensity of a patch, measurement results that exhibit a one-dimensional increase of a relationship between the application amount of the clear recording material and the reflection intensity are acquired, so that the accuracy of application amount estimation increases.

  • Patent number: 11096833
    Abstract: The present disclosure relates to methods and apparatuses for printing and drying inks on substrates. Printing systems may include a metering device positioned between a printing station and a light source. During operation, the printing station deposits ink onto a substrate to define a printed region. And the light source directs infrared light onto the substrate to define an illumination zone. The printed region is advanced from the printing station to the metering device and from the metering device through the illumination zone, wherein the ink is dried with infrared light traveling from the light source, which also heats the substrate and changes the modulus of elasticity of the substrate. In turn, the metering device isolates the printing station from the change in the modulus of elasticity to help reduce phase shifts caused by changes in the modulus of elasticity resulting from heat in the substrate.
