Abstract: The record surface of a work slip on which work contents for a printing machine are recorded with a time axis separately according to the kinds of work, is read, so that the total periods of times are obtained separately according to the kinds of work. The total periods of time are displayed, and printed out.

Abstract: A system in which data for controlling amounts of ink for a number of printing machines, having a variety of printing plates, are measured with one measuring device. This invention provides a printing image area measuring device which can detect a printing image area with high accuracy even if the surface of a printing plate is uneven, which device is simple in construction, low in manufacturing cost and high in measurement accuracy, and which can provide in-line automatic measurement in a printing line.

Abstract: A method of detecting the lengths of normal operation time and downtime, and at least approximate causes for downtime, of a printing press during each preassigned period of production time. During the progress of each production period there are derived from the printing press its electrical control signals which are indicative of the printing operation and at least approximate downtime causes. The control signals are sequentially recorded in the form of corresponding, visually identifiable marks. A visual examination of the marking provides the desired data. There is also disclosed herein a recorder of typical construction for recording the signals in the practice of the inventive method.

Abstract: A decorative laminated structure having on its surface a pattern composed of concaves and convexes which are formed by local heat shrinkages of a layer of a heat-shrinkable resin sheet employed. Such decorative laminated structure can be obtained by laying a base, a heat-shrinkable resin sheet and a picture layer containing at least a plurality of heat sensitive picture areas in a predetermined order to form a composite material, said heat sensitive picture areas being contiguous and closely adherent to said heat-shrinkable resin sheet; and irradiating the resulting composite material with a heat ray to cause said heat-shrinkable resin sheet at its portions corresponding to said heat sensitive picture areas to cave in, thus forming concaves.

Abstract: This invention provides a decorative laminated structure having on the surface a pattern composed of concaves, at least one of said concaves having an opening at its bottom portion formed by local heat shrinkage of a layer of a heat-shrinkable resin sheet employed. Such decorative laminated structure is prepared by a method comprising forming a composite layer structure including a base, a heat-shrinkable resin sheet, a picture layer containing heat insensitive picture areas and another picture layer having heat sensitive picture areas, said heat sensitive picture areas being contiguous and closely adherent to said heat-shrinkable resin sheet; and irradiating the composite layer structure with a heat ray in an amount sufficient for making an opening in the heat-shrinkable resin sheet to thereby cause the heat-shrinkable resin sheet to shrink locally and form concaves, at least one of said concaves having an opening at its bottom portion at portions corresponding to the heat sensitive picture areas.
