20230166495 · 2023-06-01 ·

Methods for printing using printing systems comprising a flexible intermediate transfer member (ITM) disposed around a plurality of guide rollers at which encoders are installed, and an image-forming station at which ink images are formed by droplet deposition by print bars onto the ITM, can include measuring a local velocity of the ITM under one of the print bars, determining a stretch factor for a portion of the ITM based on a relationship between an estimated stretched length fixed physical distance between print bars, controlling an ink deposition parameter according to the stretch factor so as to compensate for stretching of the reference portion of the ITM.

Fountain solution thickness measurement using an optical grating surface in a digital lithography printing system

According to aspects of the embodiments, there is provided a method of measuring the amount of fountain solution employed in a digital offset lithography printing system. Fountain solution thickness is measured using a diffractive optical element (DOE) configured with grating surfaces varying in a periodic fashion to hold an amount of fountain solution. When radiated with a light source the combination of the grating surface and the fountain solution therein reduces the scattering of the surface structure (“contrast”) that gives rise to a diffraction pattern. The diffractive optical element can be placed on the printing blanket of the lithography printing system or on a separate substrate.

AUXILIARY LIQUID, LIQUID SET, IMAGE RECORDING METHOD AND IMAGE RECORDING APPARATUS
20170282533 · 2017-10-05 ·

A method of recording an image on a recording medium by applying an auxiliary liquid containing a water-soluble resin and wax particles to an intermediate image formed on an intermediate transfer member, bringing the intermediate image into contact with the recording medium at a temperature higher than a melting point of the wax particles, subsequently peeling off the intermediate image from the intermediate transfer member at a temperature lower than the melting point of the wax particles and transferring the intermediate image onto the recording medium. The method can improve the efficiency of transferring the intermediate image from the intermediate transfer member onto the recording medium.
