    • PROBLEM TO BE SOLVED: To make a re-transfer ghost inconspicuous for enabling a printed matter to be easily observed.
      SOLUTION: A CPU 22 is used to apply a thin line intensifying processing for thickening the thin line width to the image data on a previous stage drum to perform a plate making processing of the previous stage drum and print processing by using the image data applied with the thin line width processing. Thereby, even if the re-transfer ghost occurs, the re-transferred ink can be concealed in a thickened thin line, making the re-transfer ghost inconspicuous to enable printed matter to be easily observed.

    • 要解决的问题:为了使得能够容易地观察到印刷品,使重新转印的重影不显眼。 解决方案:CPU 22用于将细线增强处理用于将细线宽度加厚到先前的滚筒上的图像数据,以执行前一级滚筒的印版处理和使用该图像进行打印处理 数据应用细线宽处理。 因此,即使重新发生重影,也可以将再转印的墨水隐藏在加厚的细线上,使得重新转印的重影不明显,使印刷品容易观察。 版权所有(C)2006,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a method for forming multicolored printing halftone blocks with simplicity and flexibility for adopting the rational tangent method and capable of suppressing production of moire. SOLUTION: First to third halftone blocks are halftone blocks for three colors, magenta, black, cyan deeply committed to production of moire, and a screen angle difference between the first and second halftone blocks and a screen angle difference between the second and third halftone blocks are respectively specified by a right triangle whose apex angle is 30 degrees. Then the apex angle is corrected by the ratios of the sides configuring the right triangle respectively in compliance with approximated integers to an integer multiple of the square root of three.

    • 要解决的问题:提供一种用于形成多色印刷半色调块的方法,其采用合理的切线方法并能够抑制莫尔条纹的产生,其简单性和灵活性。

      解决方案:第一至第三半色调块是三色的半色调块,深深地致力于产生莫尔纹的品红色,黑​​色,青色,以及第一和第二半色调块之间的屏幕角度差,以及第二和第二半色调之间的屏幕角度差 第三个半色调块分别由顶角为30度的直角三角形指定。 然后,通过按照近似整数的三角形的三角形的平方根的整数倍,构成正三角形的边的比例来校正顶角。 版权所有(C)2005,JPO&NCIPI
