Coreldraw 12 is used to spray the wedding carpet type of 2mx20m. What resolution is required for the background picture? What should I pay attention to when saving?

Such a large inkjet has a resolution of only 45 pixels/inch when exported, and the jet is very clear. If you export at a resolution of 72, many inkjet printers can't open your files at all, or cause inkjet printers to misread color data, leading to blind ejection. Even if you make such a high-precision picture, the inkjet printer staff will change the resolution of your source file again, otherwise it will not pop up at all, which means that the picture is made with higher accuracy. The production limit of inkjet printers can only be so. I said 45/ inch is the most ideal effect of all drawing equipment now. For example, all the paintings and portraits of Madonna and KFC are set in this way. Because I often make their things. No matter how accurate the picture is, it has no practical significance.

In addition, it is best to open the file made by coreldraw 12 with PS, and then save it as JPG with PS. Otherwise, some inkjet printers cannot recognize the color data of coreldraw 12. And set it as a CMYK file.
