因为中国的水泥袋大都印两种颜色的图案，所以工厂现在无法印四种颜色。是否可以用两种颜色代替四种颜色？需要我们制作印有两种颜色图案的样品给你们吗？

Hello.
Because China cement bags are printed in two color patterns, so the factory now can not be printed in four colors. Whether can use two colors instead of four colors? We need to make a two color pattern of the sample to you?
Business flourishes!
