Abstract: A facial covering is formed from a single sheet of material. The facial covering comprises a facial coverage region for covering part of a face of a wearer and two lateral regions for holding the facial coverage region in place on the wearer. Each lateral region comprises an ear retainer and an extending section. The extending section comprises a plurality of slits disposed such that the extending section is capable of elastic extension between the ear retainer and the facial coverage region. Methods of manufacturing and of assembling such a facial covering are also described.

Abstract: A method of calibrating a digital data writing system (20), the digital data writing system comprising a plurality of wireless communication devices (30) configured to write digital data to a first plurality of wireless communication chips (7) provided in a printed sheet (10), the method comprising: providing, to the digital data writing system (20), configuration data relating to the locations of each of the first plurality of wireless communications chips (7); selecting each wireless communication device (30) in turn and identifying, for the selected wireless communication device (30), a corresponding one of the first plurality of wireless communication chips (7) that is located in closest proximity to the location of the wireless communication device (30) within the digital data writing apparatus (20); and determining, for the selected wireless communication device (30), the relative location of the device within the digital data writing system (20).

Abstract: A printed multiple ply paper article and a method of producing it are described. The method comprises providing a first paper stock having a first surface and a second surface, applying a pressure activated adhesive (33) to the second surface, printing (34) upon the first surface, and bringing together two portions of the second surface under pressure in registration (35, 36) to form a multiple ply product.

Abstract: A method of writing digital data to a plurality of printed business cards (1) provided in a printed sheet (10), each business card comprising a wireless communication chip (7) to which the digital data is written, the method comprising: determining relevant pieces of digital data corresponding to the printed sheet (10); writing, using a plurality of wireless communication devices (30), the relevant digital data to each of the wireless communication chips (7); testing each wireless communication chip (7) to determine if there are any inactive wireless communication chips for which the digital data has not been successfully written to the wireless communication chip; and enabling positive visual identification of the inactive wireless communication chips (7).

Abstract: A multiple ply printed product and a method of producing it are described. The method comprises providing a substrate layer having a first surface supporting at least one wireless communication chip and a second surface, reverse to the first surface. A first paper stock having a first surface and a second surface is also provided. A first bonding operation is performed to substantially bond together the first surface of the substrate layer and the second surface of the first paper stock, to sandwich the wireless communication chip between the first paper stock and the substrate layer; providing a second paper stock having a first surface and a second surface. At least one of the first surface of the first paper stock and the second surface of the second paper stock may be printed on.

Abstract: A system for generating an electronic document for use in a printing process is described. The electronic document comprises a plurality of printable sheets, and each printable sheet comprises an array of printable regions. The system comprises receiving means arranged to receive content for each of a plurality of users and assigning means arranged to assign a selection of printable regions for each user in dependence on the received content for each user and to assign the content for each user amongst the selection of printable regions assigned to that user. The system is arranged to receive the content and assign a selection of printable regions such that the content for each user, varies across the selection of printable regions assigned to that user.
