The poor printing quality of pirated books will directly lead to the deviation of color expression, which will lead to the situation that the text is prone to ghosting and blurring. For children in visual development, frequent contact with such poorly printed books is likely to affect their vision and future literacy.

Identification method
Look at the cover first, which can be observed from the aspects of color, clarity, cover paper quality, book paper quality, book binding and so on. Specifically, pirated books generally have bright cover colors, muddy handwriting, thin cover paper and overflow of offset glue.
The hardcover edition may be short of inserts. Plug cloth: silk and cotton sliver cloth with tightly woven circular rib at one end. Stick it on both ends of the spine to protect the spine incision and increase the aesthetic feeling of the book. Or without front and rear ring linings.
See if there is a bar code and pricing on the back cover. If there is no barcode, it must be a pirated book.
