Figures will appear in color online and in black and white in any print format. While addressing the reviewers' comments, please check each figure carefully to ensure that (1) the figures will reproduce well when printed in black and white and (2) the descriptions in the text and in the captions are sufficiently clear for both print and online versions. It is suggested that you use shapes or patterns so the meaning is clear in color and black and white.
这是编辑给我的信让我修改。图形要求是tif或者eps或者ps格式。我有几个问题不明白，望大家帮忙！
1，the figures will reproduce well 图像能被复制，什么意思？
2，online是彩色，print是黑白，那么我该怎样上传图片（黑白？彩色？）。（要求论文和图片分开，将每个图片转成一个tif格式的文件，再上传）
3，suggested that you use shapes or patterns 建议我用shape或者pattern,是什么意思？
我的图形是在cad和excel里画的图。在这里谢谢大家！！
