摘要
目的在喷墨制版技术现有多PASS打印模式基础上,重新设计每PASS输出的控制机制,以有效提高喷墨印版图像质量和喷墨制版技术的可靠性。方法首先论证随机打印方式的机理,然后对比分析RIP后测试图在现有打印模式和随机打印模式下印版输出的版面效果。结果随机打印模式打破了每PASS横向字车方向上的规律性,抑制了影响喷墨制版质量的缺陷,显著提高了喷墨印版图文质量。结论随机打印模式有效提高了喷墨制版的图像质量。
Based on the existing multi-PASS printing mode for the inkjet plate-making technology, this article aimed to improve the image quality and the reliability of the inkjet plate-making technology by redesigning the printing method of each PASS. First, the random-print mechanism was theoretically demonstrated, and then the image effects of the plates outputted respectively in two different methods using the same one-bit-tiff file were comparatively analyzed. The experimental results showed that the random-print mode broke the regularity of every PASS in the transverse direction, inhibited the defects influencing the inkjet plate quality, and significantly improved the image quality in the inkjet plate. In conclusion, the random-orint mode effectively imoroved the image quality in the inkiet olate.
