Paper. In fact, the national standard requires the whiteness of copy paper to be below 95°, and the whiter the copy paper, the better.
The advantage of high whiteness is that the contrast is large, and the text is more eye-catching, but reading for a long time will cause eye discomfort, which is likely to cause certain harm to people’s vision, and there is a risk of blindness if used for a long time. In addition, some paper-making enterprises increase the whiteness by adding a large amount of fluorescent whitening agents in production, which not only pollutes the environment, but also causes diseases due to the additional fluorescent whitening agents.
The printing effect of special white copy paper is beautiful and clear, and it is recommended to use it for printing external texts.
The printing effect of this white copy paper is not only practical but also protects the eyes. It is recommended to use it for internal communication and information transmission.
