It was put forward that printing watermark technology is a new ideas;it has the features of low cost,simple manufacturing,and flexible watermark;it is the research trend of watermark anti-counterfeiting technology.
从防伪技术和手段出发,介绍了两种水印防伪技术——传统水印技术、印刷水印技术,并指出印刷水印技术是水印防伪研究的一种新思路,它具有成本低、制造简单、水印图案灵活的特点,是未来水印防伪技术研究的趋势。
We need a new technology to solve these problems, therefore presswork watermarking is proposed.
