  • Patent number: 11318733
    Abstract: According to aspects of the embodiments, there is provided a method of determining the amount of fountain solution employed in a digital offset lithography printing system. Fountain solution thickness is determined from diagnostic images that are printed and analyzed using the existing Image Based Controls (IBC). An analysis of the density of solids, halftones, and background as a function of the fountain solution control parameter is performed to decide on the appropriate level of fountain solution. A latitude window of control parameters is then derived for which the digital offset lithography printing system in operation minimizes the undesirable effects of too much or too little fountain solution.

  • Patent number: 11305572
    Abstract: According to aspects of the embodiments, there is provided a method of determining the amount of fountain solution employed in a digital offset lithography printing system. Fountain solution thickness is determined by examining optical density of some halftone or solid patch versus laser current level. The apparatus and method uses a variable current signal to dither or perturb the laser imaging system to irradiate a fountain solution layer to create patches at different laser current levels. An aptly programmed controller then process optical density measurements to indirectly estimate fountain solution level.

  • Patent number: 11221579
    Abstract: A printer for producing a print media moving in a process direction including a print engine, a fuser, a full width array and a duplexing path. The print engine is operatively arranged to receive the print media and to apply a first dry marking material to a first surface of the print media. The fuser is arranged subsequently to the print engine in the process direction and is operatively arranged to receive the print media with the first dry marking material applied to the first surface of the print media and to fix the first dry marking material on the first surface using at least one of heat and pressure. The full width array is arranged subsequently to the fuser and is operatively arranged to obtain a first image of the first surface of the print media, the first image being used to quantify a flatness of the print media and/or image quality of the first image. The duplexing path is arranged subsequently to the full width array.

  • Patent number: 10350828
    Abstract: 3-D printing transfers build material and support from an intermediate transfer belt (ITB) to a platen. The build material is the same as the support material, except that the build material includes a photoinitiator and the support material does not. The platen moves to make contact with the ITB, and the ITB transfers successive layers of build material and support material each time the platen contacts the ITB. The platen and a portion of the ITB that is adjacent the platen are heated prior to the platen contacting the ITB, and the same is exposed so as to crosslink polymers of build material, without crosslinking polymers of support material. The polymers of build material being crosslinked and the polymers of support material not being crosslinked makes the support material selectively soluble in a solvent.

A xerographic toner system includes a build toner material and a support toner material, the support toner material includes a PVA polymer blend including a polyvinyl alcohol (PVA) polymer and blend-additives including a chitosan and a polyvinylpyrrolidone (PVP), the amount of blend-additives is selected to adjust the Tg of the PVA polymer blend to be within about 1° C. to about 20° C. of the build material toner Tg. A method of making a support toner material includes blending polyvinyl alcohol with blend additives including a chitosan and polyvinylpyrrolidone and forming support toner particles after the blending step.
