At least a portion of an intermediate transfer member includes a release layer facing outwardly from and supported by a supportive portion. The release layer includes an inner layer and an outer layer over and in contact with the inner layer, The inner layer has a thickness of between about 1 &#x3bc;m and about 8 &#x3bc;m and a bulk swelling of between 120% and 350%. The outer layer has a thickness of less than about 5 &#x3bc;m and a bulk swelling of less than 120%.

Apparatus and methods for improving print quality and print blanket life in liquid electrostatic printing, for example, forming a first toner image on an image surface; first transferring the first image to an intermediate transfer member; then transferring of the first image from the intermediate transfer member to a final substrate; affixing the first image on the final substrate; rotating the first image to create a second image; and, repeating the method using the second image.

Apparatus and method for image and print blanket enhancement

An electrophotographic printing control apparatus serves for transferring an image via an electrically biasable ITM drum to a conductive substrate. The electrically biasable ITM drum is in contact with the conductive substrate over a contact period during which the image is transferred to the conductive substrate. The printing control apparatus includes a bias unit which provides electrical bias to the ITM drum and with short circuit protection, and a bias switching unit controllable to cut bias from the bias unit to the ITM drum during the contact period such that the ITM drum is unbiased when in contact with the conductive substrate.

Printing on conductive substrate material

A method of transferring an image on a surface to a substrate comprising: a) heating the surface to a first temperature above a temperature at which the image adheres to the substrate; b) heating the substrate to a second temperature above ambient temperature and below the first temperature; c) pressing the substrate to the surface; d) cooling the image while it is in contact with both the surface and the substrate such that it cools during said contact to a third temperature, below a temperature at which its cohesion is greater than its adhesion to the surface; and e) then separating the substrate from the surface, said image being transferred to the substrate.
