Abstract:
A method for producing a raised print on a receiver includes receiving image data and height data. The height data specify that raised printing should be produced in non-yellow region of the image data. Separation data are determined for a clear toner, a yellow toner, and at least two additional colored toners. The separation data for the clear toner is determined in response to the height data and the separation data for the yellow toner is determined in response to the image data and the height data so that the clear and yellow separations specify that respective toners be deposited one atop the other in the non-yellow region. Respective toner images are deposited on the receiver, each corresponding to respective separation data. The deposited toner is fixed to the receiver member.
Abstract:
Images produced by electrophotography are often subjected to harsh conditions, such as high temperature and high relative humidity conditions. Prints when subjected to face-to-face stacking under these conditions tend to stick and are difficult to separate without damage. Ethylene-bis-stearamide is incorporated in a protective toner formulation employing a toner binder having a higher glass transition temperature than that of the conventional CYMK colored image toners employed to provide a protective layer in fused images. Further, ethylene-bis-stearamide does not interfere with typical oil release additives used in fuser rollers. By combining ethylene-bis-stearamide with polyalkane waxes having a weight average molecular weight of equal to or greater than 2000 and a poly dispersity of less than 2.0, addition protection can be realized.
Abstract:
A method and system for printing adjustable gloss image documents using a variety of toners where some toners have a relatively low melt viscosity and others have a relatively high melt viscosity. These toners are co-printed prior to fixing, on the receiver proximate to and overlying at least a portion of each other.
Abstract:
The present invention is a toner that includes a polymeric binder and a polyethylene wax or ester wax. A dispersing agent of poly(ethylene vinyl acetate) is included in the toner that dispersed the wax and reduces the amount of free wax particles.
Abstract:
An apparatus for fixing of toner onto a receiver, including: a non-contact fuser capable of fusing one or more layers of toner on a receiver such that one or more toner layers reach a fusing temperature above a glass transition temperature. The apparatus also includes one or more cooling finish rollers located downstream from the non-contact fuser to lower the toner temperature.
Abstract:
The present invention is an electrostatographic reproduction apparatus which includes a primary imaging member (12) for producing an electrostatic latent image on a receiver, a development station (16) for applying toner particles to said latent image which forms a developed toner image on the receiver. A fuser assembly (56 ) is included for fixing the developed toner image, to form a fused toner image on the receiver. A transport member (54) is provided for transporting the receiver to or from the fuser assembly (56), the transport member having a substrate bearing an oil-absorbing layer that includes transparent aluminum inorganic particles of pseudo-boehmite, dispersed in an organic binder, and a wax having a melting point below the 100°C.
Abstract:
A fluorescing dry toner particle comprises a polymeric binder phase comprising a non- fluorescing binder polymer and a polymeric fluorescing colorant dispersed within the non- fluorescing binder polymer. The polymeric fluorescing colorant comprises a fluorescing moiety that is covalently attached to a colorant polymer that is the same or different than the non- fluorescing binder polymer, but the polymeric fluorescing colorant is blendable with the non- fluorescing binder polymer to form a homogeneous polymeric binder matrix, and is present in an amount of at least 1 weight % and up to and including 40 weight %, based on the total fluorescing dry toner particle weight. These fluorescing dry toner particles can be used in various dry developers to provide fluorescing toner images with or without non- fluorescing color toner images.
Abstract:
A nonporous dry toner particle has a polymeric binder phase and non- conductive metal oxide particles dispersed therein. The nonporous dry toner particle has a mean volume weighted diameter (Dvoi) before fixing of at least 15 μηι to 40 μηι. The non-conductive metal oxide particles have as aspect ratio of at least 5 and an ECD of at least 2 μηι. They are present in an amount of at least 15 to50 weight % based on total nonporous dry toner particle weight. The ratio of the nonporous dry toner particle Dvoi to the ECD of the non-conductive metal oxide particles in the nonporous dry toner particles, before fixing, is greater than 0.1 and up to and including 10. These nonporous dry toner particles can be included in dry one- component or two-component developers and used to form electrophotographic printed toner images exhibiting special effects such as a metallic effect.
Abstract:
Electrographic printing of one or more toner layers having a particular pattern by electrographic techniques so that one layer acts as an adhesive, when fixed, for a thin film. Such electrographic printing comprises the steps of forming a desired print image, electrographically, on a receiver member utilizing marking particles; and applying the thin film in registration before activating the toner.
