✔ On the surface of paper  no folds, wrinkles, glossy stripes, transparent spots and holes that are visible to the naked eye are allowed.  
✔ Subtle folds, wrinkles, glossy stripes, transparent spots and holes, that can not be detected during the manufacturing process, are allowed if the index of these intra-roll defects does not exceed 3.0%.
