Abstract: This invention provides improved components (e.g. array “pins”, print head, substrate platen, print head platen, and the like) for microarray printing devices as well as microarray printing devices incorporating such components. In one embodiment, this invention provides a microarray print head comprising a plurality of glass or quartz spotting capillaries disposed in a support that maintains a fixed spacing between the spotting capillaries and that permits the spotting capillaries to move in a direction parallel to the long axis of the capillaries.

Abstract: A lottery ticket having a substrate layer with game data printed in a game area and which is arranged to prevent access to the game data from a rear surface of the substrate and has at least one fixing layer applied over the game data in the game area so as to prevent release of the printed game data from the substrate layer and at least one opaque scratch-off layer applied over the sealing layer, the scratch-off layer being arranged such that it separates from the sealing layer and breaks down into fragments when scratched by a player, is modified by the addition of an adhesive layer applied over at least a part of the opaque scratch-off layer and a metal layer attached to the adhesive layer. The metal layer and the adhesive layer are arranged such that they break down into fragments with the scratch-off layer when scratched by the player and may provide both enhanced security and an improved appearance.
