摘要:
Imaging methods, imaging devices, transfer assemblies, and transfer member lubrication assemblies are described according to some aspects. According to one aspect, an imaging method includes forming a latent image using a first imaging member, using a marking agent, developing the latent image providing a developed image, after the developing, first transferring the marking agent of the developed image to an imaging transfer member, after the first transferring, second transferring the marking agent of the developed image from the imaging transfer member, and lubricating the imaging transfer member during the first and the second transferrings.

In one example, a printer sheet holding system includes: a support for printable substrate sheets in a support area; and a movable indicator to indicate the presence in the support area of a second sheet stack on top of a first sheet stack. The indicator being movable between a first position in which the indicator extends over the support area where it can rest on top of the first stack when a first stack is supported in the support area and a second position in which the indicator is withdrawn from the support area. In another example, a method includes sensing the presence of a second stack of printable substrate sheets on top of a first stack of printable substrate sheets and, in response to sensing the presence of the second stack on the first stack, configuring the printer to print on sheets of the second substrate.
摘要:
An embossing die is created by printing multiple ink layers (530, 540) in superposition thereby to build up a printed relief pattern (510) in accordance with received design data specifying a design to be embossed. The design data is modified after receipt to introduce into the printed relief pattern to be built, one or more channels (610) which extend depth-wise through multiple ink layers of the printed relief pattern (510) and serve to fully or partially segment the printed relief pattern.
摘要:
An embossing apparatus includes an embossing die that includes a printed relief pattern made up of multiple layers of a deposited material. A resilient surface presses media against the embossing die such that embossed features corresponding to the embossing die are formed in the media. A method for embossing media includes forming an embossing die by depositing multiple layers of ink on a impression layer to form a relief pattern and pressing media against the embossing die to transfer the relief image to the media.
摘要:
An embossing apparatus comprises an embossing die comprising a printed relief pattern, and a resilient surface for pressing media against the embossing die to emboss features corresponding to the printed relief pattern on the media, in which the printed relief pattern comprises a number of layers of a deposited material, and in which a number of layers of the deposited material closest to the top of the printed relief pattern comprises a deposited material with a relatively lower coefficient of adhesion than layers of the deposited material disposed under the deposited material closest to the top of the printed relief pattern. A printed relief pattern for embossing media comprises a number of preliminary layers, the preliminary layers comprising a first material, and a number of terminal layers, the terminal layers comprising a second material, in which the second material has a lower adhesive coefficient than the first material.

摘要:
There is disclosed a computer program product for carrying out a method of calibrating a thickness of an embossing die, the embossing die being formed from a plurality of ink layers printed by an apparatus. According to the method, an average thickness of an ink layer printed by the apparatus may be calculated, and a target die thickness may be calculated as a function of the average ink layer thickness. A system for implementing a method of calibrating a thickness of an embossing die and a method of measuring a thickness of an embossing die are also disclosed.

The present disclosure is drawn to compositions and methods for a liquid electrophotographic ink printing. The composition comprises a liquid vehicle; ink particles; and a charge director system, comprising i) a primary charge component, ii) a secondary charge component, and iii) an electrical stability additive; such that the charge director system provides the following ink conductivities: a high field conductivity of about 100 pS/cm to about 500 pS/cm, a low field conductivity of about 20 pS/cm to about 200 pS/cm, a direct charge conductivity less than about 30 pS/cm, and a particle conductivity of at least 100 pS/cm. Additionally, the liquid electrophotographic ink can be formulated for printing from a liquid electrophotographic printer.
摘要:
An image forming apparatus includes a determination unit, a print unit, and an image forming blanket. The determination unit may determine a raised support image having a support perimeter to be printed on an impression media corresponding to a type of media. The print unit may at least one of print the image to be transferred by the image forming blanket to the media and print the raised support image determined by the determination unit on the impression media. The support perimeter may be smaller than the media perimeter. The image forming blanket may transfer the image to a front surface of the media from the image forming blanket by contacting the media and bending the edge portion of the media about the raised support image.
