Abstract: An identification structure and method for temporary or short term identification of a portion of a surface or substrate. The structure and method include the use of viscous material which is displaced by pressure applied thereto and which retains its displaced condition until smoothed out by any suitable means. Preferably, the viscous material is enclosed in a substantially flat bag which has opposed transparent portions. The viscous material is visible but also has a high degree of transparency. Identification of a portion of a surface or substrate is made as the bag is positioned immediately above or adjacent thereto or in engagement with the surface or substrate. All portions of the surface or substrate are normally visible through the bag and through the viscous material. Pressure is applied to the bag immediately above the portion of the surface to be identified.

Abstract: A duplication printer has a movable base slidably accommodated in a frame case and provided with a cushioning layer on which a relief plate bearing a relief pattern on top is placed, and then, on the relief plate, are stacked successively from bottom to top a paper sheet, a transfer sheet having a lower surface of an ink layer facing the paper sheet, a tacky sheet with a tacky layer on its upper surface, and a display sheet having light transmitting characteristic. The movable base is positioned within the frame case and is drawn outwardly from the frame case, a pressure bar passes relatively over the stack of sheets, whereupon the relief pattern is printed via the ink layer on the paper sheet and, simultaneously, the image of the pattern is displayed on the display sheet. Thus, the pattern on the display sheet can be observed by an operator without removing the paper sheet from the printer.
