Is it clear to photocopy Pinduo's books?

Is the book photocopied by Pinduo clear? The photocopied book is not very clear. Photocopyed books are in principle copied directly from the original, and then scanned and printed twice. The photocopied book is not clear enough. Photocopyed books are scanned and printed twice, and paper quality and scanning distortion should be considered when printing, which will affect the quality of photocopied books. Photocopyed books are first copied with the original books, then printed through the first scanning process, and then stored and printed through the second scanning. This method is not often used now, and the sales of photocopied books are generally not very good because of their poor quality.
