A binding strip includes a substrate having an interior surface and an exterior surface, a spine-alignment edge, a free edge opposite the spine-alignment edge and substantially non-perpendicular thereto, a face-attachment portion of the exterior surface adjacent to the spine-alignment edge, and a wraparound portion of the interior surface adjacent to the free edge. A border is defined laterally between the face-attachment portion and the wraparound portion and substantially parallel to the spine-alignment edge. An adhesive layer is arranged over the wraparound portion. A first spacer is affixed to the interior surface opposite the face-attachment portion so that a fastener area is defined. The spacer has a selected thickness.

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.

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.

Sheets are bound to form a bound document by fastening together the sheets and a binding strip. A spacer is applied to a back sheet adjacent to the feet of the fasteners. A wraparound portion of the binding strip is folded around the spine edges of the sheets so that adhesive on the strip contacts the spacer or the back sheet farther from the spine than the feet of the fasteners. The adhesive is affixed to the back sheet. The binding strip includes a spacer adjacent to the heads of the fasteners, protruding above the face-attachment portion at least as far as the heads of the fasteners do.

A method and apparatus for fusing a heat curable toner to a carrier sheet having said toner thereon. In the method, the toner is sandwiched between said carrier sheet and a movable fuser belt and heated to a first temperature by a first means, which first temperature is above a first glass transformation temperature of the toner. The toner is kept at an elevated temperature for a predetermined time by a second means, which elevated temperature is above the first glass transformation temperature, thereby raising the glass transformation temperature of the toner to a second glass transformation temperature. The apparatus has at least a first endless fuser belt, first heating means for heating the toner to a first temperature, second heating means located downstream of said first heating means for keeping the toner at an elevated temperature for a predetermined time and control means for controlling the first and second heating means.

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.

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.
