Abstract: A sheet-like printing medium with easy-separating means which enables one to easily separate the printing medium into separate portions. When an image is formed on the printing medium having easy-separating means disposed inside and entirely along the peripheral edge thereof, a print area is extended slightly to the peripheral edge beyond the easy-separating means. When the width of a non-print area left in the peripheral edge of the print area is separated at a part of the easy-separating means, an image is formed spaced from the sides of each of the non-print areas by a predetermined distance.

Abstract: A label making inkjet printer applies print imaging directly to the adhesive side of a media provided in sheet-form and in reel-form. Because inkjet printing is a non-contact printing method, print imaging may be applied to the adhesive side of the media. According to one embodiment, a user manually pulls tape-form media through the printer while encoding signals detect linear movement of the media and provide basis for synchronizing operation of an inkjet print head. According to another embodiment, a motorized media transport carries tape-form media on a pair of media transport belts past an inkjet print head. The resulting adhesive label when applied to a contact surface substantially disappears due to its transparent nature leaving visible only print imaging applied thereto and captured between the protective tape media and contact surface therebelow.

Abstract: The present invention pertains to the register coordination of cylinders of a web-fed rotary printing press which print on a web, wherein a first cylinder printing on one side of the web is driven by a first motor and a second cylinder printing on the same side of the web is driven by a second motor. An angular position of the second cylinder is coordinated with the first cylinder in good register by a controller. In the case of a change in a production condition, at least one controller parameter (kP, kD, kI, kf) of the controller is changed and the controller setting is adapted to the production condition as a result.

Abstract: An apparatus for applying printed matter to the running web of cigarette paper or the like in a machine for making rod-shaped smokers' products employs a roller train which transfers printing ink from one or more sources to a rotary carrier of one or more stamps serving to apply trademarks, manufacturer's names and/or other printed matter to longitudinally spaced apart portions of the running web. At least one roller of the roller train has a resilient cylindrical outer layer which contacts the peripheral surface of at least one other roller of the train and surrounds an adjustable rotary eccentric which biases the cylindrical outer layer against the at least one other roller with a force determined by a prestressed coil spring. The eccentric is oscillatable axially against the opposition of a second spring, such as a diaphragm spring.
