1. Our printing machines were installed color system ,so the color wont be changed for the same artwork
2. Workers will cut the printed graphic into pieces from rolling ,if there is dirty on it ,workers will jet them out .
3. Before packing ,our QC will double check each piece ,if they are ok then put them into the carton
4. at last ,we will count the all of the number that quality is ok ,then will reprint them that quality can not pass through.
