Abstract

PURPOSE:To obviate the production moires by forming facing materials larger than the size of printed paper, and providing modulated groove lead-out parts on the facing materials at the sizes roughly equal to the inside circumferential parts of modulated grooves. CONSTITUTION:An upper die 1 and a lower die 2 are pivotally fitted to each other, and stampers 3, 4 are disposed respectively on the inner sides thereof. A central shaft 5 is provided to the lower die 2. Steam and cooling water are passed in passage 6 within the upper, lower dies 1, 2 so that both heating and cooling can be made. The 1st facing material 7 consisting of a transparent or translucent thermoplastic resin, the printed paper 8 printed on with the 1st writing surface, photograph, etc., a core material 9 gelled by heating, the printed paper 8' printed on with the 2nd writing surface, photograph, etc., and the 2nd facing material 7' consisting of a transparent or translucent thermoplastic resin are inserted successively onto the central shaft 5 of the lower die 2. The facing material 7 is made larger than the printed paper, is formed with modulated groove lead-out grooves at the pressing and covers the printed paper 8.
