I found a tutorial for you to learn. The shoe label mainly looks at:
1)logo is very sleek, and many fake labels will be printed with rough deformation;
2) Pay attention to the alignment of letters and letters and the alignment of letters and numbers in each part;
3) Pay attention to the format of the barcode. There are only two kinds of real labels: thick line and thin line;
In the size column, the letters of US, UK, EUR and cm should be roughly equally spaced;
5) Of course, there must be UPC codes, and the spacing between letters and numbers in a row of UPC codes should be equal.
I think it is helpful to you, and I hope it can be chosen as a satisfactory answer.
If you have any questions, you can ask me or answer them. Thanks for your encouragement and support.
