Description

Technical Field

[0001] The invention belongs to the technical field of paper printing, and in particular relates to a printing technology and a printing method capable of protecting eyesight. Background Art

[0002] With the popularization of electronic products such as mobile phones and tablets, myopia among students has become more and more common. Existing printing technology for students generally uses relatively glaring high-white paper, and the reflection during reading and writing can cause further damage to eyesight.

[0003] The existing eye protection printing technology only reduces the reflective effect of paper by changing the printing paper, and the eye protection effect is limited. Scientific research shows that color also has an impact on vision. Therefore, it is necessary to design a printing technology that can relieve visual fatigue and protect vision through paper color. Summary of the invention

[0004] The purpose of the present invention is to provide a printing technology and a printing method capable of protecting eyesight, so as to solve the current situation that the existing printing technology causes harm to eyesight.

[0005] In order to achieve the above object, the present invention provides the following technical solutions: A printing technology capable of protecting eyesight, the technology uses virgin white paper as a raw material, the virgin white paper is printed with green lines and light yellow blocks, and by using a printing technology combining light yellow and green, the paper surface is neither too bright nor too dark, thereby effectively protecting the reader's eyesight; Furthermore, the basis weight of the raw pulp white paper is ≥65.0 g / m 2 ; Furthermore, the double-sided smoothness of the raw pulp white paper is ≧20s; Furthermore, the D65 brightness of the raw pulp white paper is 55.0%-85.0%; Furthermore, the D65 fluorescence brightness of the raw pulp white paper is ≤5.0%.

[0006] Furthermore, the chromaticity value of the light yellow color block is 13%-17%.

[0007] The beneficial effects of the present invention are: 1. Use virgin white paper to meet the requirements of green printing and environmental protection, reduce the harm of paper fluorescence, make the light more uniform when writing, and reduce the burden on the eyes.

[0008] 2. The green lines serve as a visual guide, which can not only improve writing efficiency, but also effectively relieve the visual tension caused by writing for a long time.

[0009] 3. The printing of yellow solid background has less stimulation to the eyes and can also improve concentration, making you more focused when writing, reducing visual fatigue caused by distraction, and protecting eyesight to prevent myopia.

[0010] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a schematic diagram of an application of a printing technology capable of protecting eyesight shown in an embodiment of the present invention. DETAILED DESCRIPTION

[0012] Scientific research shows that looking at green has a significant effect on protecting eyesight. The main reasons why looking at green is good for the eyes are as follows: 1. Adjust the curvature of the retina: The wavelength of green light is in the center of the visible spectrum of the human eye, which can adjust the curvature of the retina of the eye. This helps relieve eye fatigue, protect eyesight, and keep the eyes relaxed.

[0013] 2. Reduce glare and other discomfort symptoms: Green absorbs and reflects light moderately, which can reduce the glare and other discomfort symptoms caused by strong light to the eyes. Compared with colors such as yellow and red, green reflects light more gently, which helps protect the eyes from the stimulation of strong light.

[0014] 3. Relieve nervous tension: Green is a cool color and can effectively relieve nervous tension. This helps to reduce the tension of eye muscles and relieve eye fatigue.

[0015] 4. Promote blood circulation around the eyes: Exposure to green can also promote blood circulation around the eyes, thereby improving visual fatigue. Good blood circulation helps provide more nutrients and oxygen to the eyes, keeping the eyes healthy.

[0016] The technical solution of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0018] A printing technology capable of protecting eyesight is shown in a preferred embodiment of the present application. The technology uses raw pulp white paper, and its specific parameters are as follows: 1. Paper weight ≧65.0g / m 2 ; 2. Paper double-sided smoothness ≧20s; 3. D65 brightness: ≧55.0%, ≦85.0%; 4. D65 fluorescence brightness: ≦5.0%.

[0019] Green lines are printed on the white paper, and the green lines form squares, a grid, four lines and three grids for writing English, or other arbitrary line patterns.

[0020] At the same time, scientific research shows that yellow also has a good effect on vision protection, especially light yellow, which can reflect a specific spectrum of light and can effectively improve the impact of white full-screen light on vision. It is soft and will not cause irritation to the eyes, and can achieve the effect of preventing myopia.

[0021] On this basis, the present invention adopts a printing technology that combines light yellow and green, so that the paper surface is neither too bright nor too dim, which provides a layer of protection for the eyes and makes reading easier and more enjoyable.

[0022] Specifically, light yellow blocks are printed between the green lines, and the chromaticity value of the light yellow blocks is 13%-17%.

[0023] The present invention soothes the visual nerves and reduces eye tension through the green lines, and at the same time uses the light yellow background color block to echo the green lines to prevent the lines and the color of the white paper from being too abrupt, thereby creating a suitable writing and reading environment and effectively protecting eyesight.

[0024] Specifically, the printing method of the above printing technology includes the following steps: 1. Prepare virgin white paper that meets the above requirements.

[0025] 2. Print green lines on white paper, and then print light yellow blocks within the range of the lines.

[0026] 3. Bind into a book.

[0027] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
