Disclosed herein is a method for concentrating an ink composition, wherein the method comprises the steps of:

Concentrating an ink composition

The present disclosure relates to a method for concentrating a substance, which may be an electrostatic printing ink. An apparatus for concentrating a substance is also described.

Concentrating substances

The present application relates to a method for concentrating an ink for an electrostatic printing process, wherein the method comprises the steps of:

Method and apparatus for concentrating an ink for an electrostatic printing process

A printing system utilizing inks with high solids content includes a mixing unit for receiving a high solids content ink and producing a concentrated ink and an interim tank for receiving the concentrated ink from the mixing unit. An ink tank receives the concentrated ink from the interim tank and produces printing ink. An liquid electro-photographic print engine receives the printing ink from the ink tank. A fluid return line is connected between the mixing unit and at least one of the interim tank and the ink tank, the mixing unit receiving fluid from at least one of the interim tank and the ink tank and mixing the fluid with the high solids content ink. A method for liquid electro photographic printing using high solid content ink is also provided.

Printing systems utilizing inks with high solids content

A method of heating toner of an image on a moving surface of an intermediate transfer member in order to transfer the image to a printing medium of a printing system includes providing a toner image on an intermediate transfer member, and placing a surface of a heated member in contact with the toner image on the intermediate transfer member prior to transferring the toner image to a further surface from the intermediate transfer member. Heating of the toner image by the contacting heated member is in addition to heating by a heater internal to the intermediate transfer member.

Ink heating on blanket by contact of a rotating hot surface

Apparatus for transferring visible images from a first surface to a second surface and/or for fusing or fixing a visible image to a substrate, comprising: a cylindrical member secured between two round end plates to form a cylindrical structure; a volatile liquid incorporated within the cylindrical structure in a cavity, at least one wall of which is thermally connected to the cylindrical member; and a heater that heats the liquid to an operating temperature, wherein the amount of the volatile liquid is such that all of the volatile liquid would be evaporated at a temperature that is less than about 20&#xb0; C. above the operating temperature.

Fuser and intermediate transfer drums

A method for printing an image on a surface of a substrate having a surface finish defined by a gloss, the method comprising: printing an image on the surface of the substrate, such that image areas thereof have a thickness, when fixed to the substrate and dry, of less than about 6 micrometers of a thermoplastic material; and smoothing the surface of at least a portion of the thermoplastic material.

Method for producing high gloss printed images

An apparatus for use as an intermediate transfer member or fusing member in an image forming device includes a cylindrical member having a thickness that is insufficient to support it in use and which is secured between two round end plates to form a cylindrical structure which is unsupported between the endplates. A liquid is incorporated within the cylindrical structure and a heater is also located within the cylindrical structure so as to heat the liquid to produce a vapor wherein the vapor is of a sufficient pressure to support the cylindrical member during use.

Imaging apparatus including an imaging surface having a toner image formed thereon and an intermediate transfer member, which receives the toner image from the imaging surface and from which it is subsequently transferred. The intermediate transfer member includes a drum having mounting recesses formed therein and an intermediate transfer blanket mounted on the drum. The blanket has a layered transfer portion having a transfer surface on one face thereof which receives the toner image and optionally an adhesive layer on the opposite face thereof and a mounting fixture, attached to one edge of the layered transfer portion and adapted to mate with the mounting recesses in the drum, whereby the transfer blanket is fixedly and removably mounted on the drum.

Imaging apparatus and intermediate transfer blanket therefor

A ribbon ink has a viscosity that increases with increasing rate of shear for rates of shear greater then a predetermined value. A printer ribbon for use with an impact printer comprises a substrate containing ink having a viscosity that increases with increasing rate of shear for rates of shear greater then a predetermined value.

Ink and multistrike ribbons incorporating the same

Dispersion apparatus for dispersing a first material in a second material comprising an enclosure having disposed therein an apertured divider defining first and second sub-enclosures within said enclosure on opposite sides of said divider, a first inlet for said first material communicating with said first sub-enclosure, a port for said second material communicating with said second sub-enclosure, and means for enhancing the passage of materials through said divider.
