摘要:
A bound document has front, back, and interior sheets with spine edges. The document has a binding strip and fasteners binding the sheets and the binding strip together. The strip has a flexible substrate with a face-attachment portion through which the fasteners are driven, and a wraparound portion that is bent so adhesive on the wraparound portion contacts the back sheet farther from the spine edge of the book than the feet of the fasteners. The strip also has a first spacer affixed to the interior surface opposite the face-attachment portion so that a fastener area is defined, the spacer at least as thick as the protrusion of the heads of the fasteners above the face-attachment portion.

The invention describes a method to control differential gloss of halftone areas produced using substantially clear or low-pigmented toner. It is an objective of this invention to provide a method which allows to produce digital watermarks on paper without being limited in the gloss properties of the toner, the paper or and selected fusing technology. The present invention relates to a method producing clear, low density or highdensity watermarks using Glossmark technology using low-pigmented toner or clear toner. Glossmark technology is for controlling the differential gloss of an image using the steps selecting a first halftone image having a first anisotropic structure, selecting a second halftone image having a second structure different from that of the first halftone, applying the first halftone to at least some portion of the halftone image and applying the second halftone to another portion of the halftone image.

摘要:
A heating device for heating at least one printing agent on a printing material which is moved along a transport path through said heating device includes a microwave applicator. A microwave absorber element is located in an outer perimeter of the microwave applicator. The microwave absorber element is an irradiation device that absorbs microwave radiation and emits electromagnetic radiation. The electromagnetic radiation can be applied to the printing agent or the printing material.

A method for producing an antenna structure for an RFID device, a dry toner for use in producing an antenna for an RFID device and a RFID device comprising an antenna structure made of fused toner are disclosed. In a method for producing an antenna structure for an RFID device, a dry toner comprising a polymeric binder and metallic particles is provided. The toner comprises particles having a resistance allowing triboelectric charging or a resistance allowing inductive charging, wherein said metallic particles are nanoparticles having a mean particle size below approximately 500 nm in at least one direction. In the method, a continuous layer of the dry toner is applied to a substrate in a desired shape of an antenna via an electrophotographic printing process, and subsequently the toner is fused to the substrate by heating the toner above its glass transformation temperature. The dry toner for use in producing an antenna for an RFID device comprises toner particles having a resistance allowing triboelectric charging or a resistance allowing inductive charging. The toner particles comprise a polymeric binder and metallic particles, wherein said metallic particles are nanoparticles having a mean particle size below approximately 500 nm in at least one direction.
摘要:
The invention describes a method providing prints with fluorescent effects on a document generated by color electrophotographic print processes, employing an electrophotographic printer equipped with five print modules, where four printing stations are equipped with black, yellow, magenta and cyan toners and a fifth station is equipped with substantially clear fluorescent toners to be printed on top of the color toners or directly on a substrate of the print document. In further developments of the present invention, the clear fluorescent toner absorbs light in the UV-A range or comprises metallic pigments or metallic effect pigments added to the clear fluorescent toner.

Treating a transport mechanism (5) for transporting print material (2) in a printing press (1) that uses toner in which oil-bearing substances (27) adhere to the transport mechanism (5). A cleaning device (30) is provided with at least one cleaning element (33) movable relative to the surface of the transport mechanism (5) for application of at least one oil-repelling substance (37) that reduces the adherence of the oil-bearing substances (27) to the transport mechanism (5). Accordingly, this cleaning element (33) can strip the surface of the transport mechanism (5) of oil-bearing substances (27).
摘要:
A microwave fuser apparatus, for a reproduction apparatus, the microwave fuser apparatus having at least two microwave applicators, staggered relative to a receiver member transport path with an area of overlap, for applying microwave energy to a receiver member traveling on such transport path relative to the microwave applicators to have toner images fused thereto. The microwave fuser apparatus has at least one additional microwave applicator, located adjacent to the overlapping area between the at least two staggered microwave applicators that applies microwave energy to the receiver member. The at least one additional microwave applicator effectively maintains an elevated temperature of a receiver member.
摘要:
A carrier or substrate for a photoconductor to be used for the formation of an electrophotographic recording element, particularly an imaging drum for an electrophotographic printing press, wherein the carrier is made of a metal or a metal alloy, preferably of aluminum, is prepared wherein the surface of the carrier supporting the photoconductor, used to form a barrier layer, is oxidized, preferably by etching and/or anodizing. The oxidized surface of the barrier layer is sealed with a sealing material following oxidation, and a preservative or impregnating agent is used as the sealing material.
