烟用接装纸烫印面积比的两种计算方法

Two Methods for Calculating Stamping Area Ratio of Tipping Paper

为准确测定烟用接装纸烫印区域的面积比例,采用Photoshop软件和ImageJ软件进行计算,并探讨了两种方法的准确性、重复性和适用范围。结果表明,对于绝大多数接装纸,两种方法都能准确地计算出烫印面积比,方法误差小于0.62%,且成本低、重复性好。通过比较发现,Photoshop法计算更准确,适用范围更广;而ImageJ法计算更快捷。

Photoshop software and ImageJ software were used to calculate the stamping area ratio on tipping paper,and the accuracy,repeatability and application range of the two methods were compared.The results showed that： 1） For most kinds of tipping paper,the stamping area ratio could be calculated accurately by either of the two methods with an error of less than 0.62% in addition to low cost and good repeatability;2） Photoshop method was more accurate and widely available,while ImageJ method was more efficient.
