Anti-shortsightedness exercise book and printing method thereof

Abstract

The invention discloses an anti-shortsightedness exercise book. The anti-shortsightedness exercise book comprises exercise book pages, horizontal lines or vertical lines are printed on the exercise book pages, and the horizontal lines or the vertical lines are formed in the mode that round dots with the diameters of 0.05-0.1 millimeter are arrayed in sequence; the distance between every two adjacent horizontal lines or vertical lines is 0.05-9 millimeters, the horizontal lines are parallel to or vertical to one another, and the vertical lines are parallel to or vertical to one another. The printing method comprises the following steps that typesetting and platemaking are conducted; printing ink mixing is conducted; printing is conducted, wherein each page is printed with an ink line coating, the shapes of all the vertical lines on the same page are identical, and the shapes of all the horizontal lines on the same page are identical; the spacing distance between every two adjacent horizontal lines is identical, and the spacing distance between every two adjacent vertical lines is identical; the pages are bound in a volume. The anti-shortsightedness exercise book has the advantages that off-white round dots are used for forming the lines for printing so that the pages can be softer, and the eye fatigue condition is greatly relieved, which helps to prevent shortsightedness.

Description

technical field [0001] The invention relates to the technical field of preventing myopia, in particular to an exercise book for preventing myopia and a printing method thereof. Background technique [0002] At present, the paper used in most books is white, which is characterized by strong brightness, which is convenient for handwriting recognition. However, due to its strong white reflection, the eyes are easily fatigued, which is one of the reasons for inducing myopia. The book book for myopia reduces the brightness of the background while increasing the color, reflecting the color light of a specific spectrum, which improves the stimulation of the vision by the white full-spectrum light, and prevents myopia to a certain extent. [0003] However, the main difference between the paper used in the existing anti-myopia booklet and the ordinary white paper is only the color difference, and the printing surface roughness of the pages of these papers is very small. However, the...

Problems solved by technology

However, the visual environment is also affected by the surface processing characteristics of the page. A page polished to an ideal mirror surface reflects the incident light of the light source almost 100%. If the size is large, the reflected light on the page will stimulate people's eyes more, so the existing anti-myopia booklets have limited preventive effect on juvenile myopia
