摘要： What is disclosed is system which facilitates the application of a mark to a surface of an object in a direct-to-object print system and a direct-to-object print system configured to use various embodiments of the present marking system. The present marking system comprises a camera for capturing an image of an object retained by an object holder configured to slideably traverse a support member positioned to be parallel to a plane formed by at least one printhead configured to eject in onto a surface of the object. A processor receives an image of an object held and communicates the image to a display. A mark to be printed on the object is retrieved and overlaid on the object in the image. A location of the overlaid mark is determined and communicated to a controller which causes the printhead to print the mark on the object at the location.

摘要： What is disclosed is an object holder for retaining an object in a direct-to-object print system and a direct-to-object print system configured to use various embodiments of the object holder of the present invention. In one embodiment, the object holder comprises a shuttle mount configured to slideably traverse a support member positioned parallel to a plane formed by the printhead. At least one collapsible membrane is attached to the shuttle mount. The membrane forms an airtight sack filled with granules. The membrane collapses at least partially around an object when a volume of air is withdrawn from the membrane by a vacuum pump. The vacuum pump withdrawing a volume of air from the membrane causes the membrane to collapse and tightly pack the granules inside the membrane. The vacuum-packed granules cause the membrane to conform to the shape of the object thereby securing the object to the shuttle mount.

摘要： A drag force sensor on a fountain solution carrier roller surface measures drag force of a fountain solution layer on the fountain solution carrier roller surface in real-time during a printing operation. The measured drag force is used in a feedback loop to actively control the fountain solution layer thickness by adjusting the volumetric feed rate of fountain solution added onto the imaging member surface during a printing operation to reach a desired uniform thickness for the printing. This fountain solution monitoring system may be fully automated.

摘要： A coefficient of friction (COF) sensor on a carrier roll surface wetted with fountain solution transferred from an imaging member measures COF of the wetted carrier roll surface in real-time, even between or during printing operations. The transferred fountain solution may be concentrated and/or chilled to solidify before the measurement. The measured COF is used in a feedback loop to actively control the fountain solution layer thickness by adjusting the volumetric feed rate of fountain solution added onto the imaging member surface during an imaging or other printing operation to reach a desired uniform thickness for the printing. This fountain solution monitoring system may be fully automated.

摘要： 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 glass roll at a lower temperature than the fountain solution. The lower temperature causes the fountain solution to undergo a change in state and in a solid state the fountain solution crystalizes and changes roll opacity with the thickness of the film. When radiated with a light source the opacity is continuously measured through the surface of the roller. The thickness of the crystallized fountain solution can then be determined via the opacity level increase by the crystallization and the impact to the opacity on the glass roll.

摘要： 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.
