What equipment is used to scan ancient periodicals? This color reproduction is better.

Because the ancient books are relatively old, it is recommended to use V-type, the tension is not very great, the color of the area ccd is well restored, and it will not radiate to the paper when it is collected at one time. There is a kind of light band that radiates back and forth, which is not good for health. There is a foreign and domestic image that loves book2net, but other brands don't recommend it, so there is no comparability.
