    • PURPOSE:To reduce the frequencies of exchanging doctor knife and also of repairing intaglio printing roll by allowing more or less abrasion of the doctor knife and the intaglio printing roll by preventing the adherence of remaining ink on the surface of the intaglio printing roll to a soft sheet by means of a protective plate provided between the intaglio printing roll and the soft sheet. CONSTITUTION:A wire 9 of a diameter of 3mm. is laid in parallel with the rotary shaft of an intaglio printing roll 3 in the neighborhood of the inlet side of the roll 3, and a 0.3mm. thick steel protective plate 6 is attached to the wire 9 in such a way as to cover the upside of the end portion of the roll 3. In printing, a long soft sheet 1, e.g., a thin soft synthetic resin sheet, etc., is passed through between the roll 3 and a letterpress printing plate-pressing rubber roll 5, ink in an ink bath 2 is put on the roll 3, and excessive ink is raked out by the doctor knife 4. The soft sheet 1 is pressed on the surface of the roll 3 by means of the pressing projection 8 of the rubber roll 5 to transfer ink in the printing recession 7 of the roll 3 to the soft sheet 1.
    • 目的:为了减少更换刮刀的频率以及修复凹版印刷辊,通过防止刮刀和凹版印刷辊或多或少的磨损,防止凹版印刷辊表面上残留的油墨粘附到柔软 通过设置在凹版印刷辊和软片之间的保护板。 构成:直径为3mm的电线9。 与辊3的入口侧附近的凹版印刷辊3的旋转轴平行地放置,并且为0.3mm。 厚钢保护板6以覆盖辊3的端部的上侧的方式附接到线9.在印刷中,长的软片1,例如薄的软的合成树脂片等, 通过辊3和凸版印刷板压制橡胶辊5之间,将油墨2中的油墨放在辊3上,并用刮刀4将多余的油墨耙出。软片1被压在 辊3的表面通过橡胶辊5的按压突起8将墨辊3的印刷凹部7中的墨转印到软片1上。
