If the background color of the front and back sides of the fabric is the same (because it is matching dyeing), the pattern is white or different from the background color, and the background color is dark, it can be confirmed that it is a printed fabric.
If you check the back of the pattern carefully, there will be traces of the original background color (the reason for this phenomenon is that the chemicals that destroy the dye cannot completely penetrate into the back of the fabric).
