您产品标签是不干胶吧,如果是铜板纸是可以用喷黑打印免强打印上,喷墨打印机一般用相片纸打印效果才会好,如果用不干胶PET、PVC、合成纸等相关标签就打印不上或效果很差的。
Your product labels are self-adhesive, right? If they are coated paper, you can use black inkjet printing to print them. Inkjet printers generally use photo paper for better printing results. If you use self-adhesive PET, PVC, synthetic paper and other related labels, you will not be able to print or the effect will be very poor.
