Problems solved by technology

[0003] On the other hand, with the development of social economy, people have higher and higher requirements for entertainment or game types and effects. They need entertainment toys with novel effects, strong fun, good safety, low cost and sustainable use. Not many products meet the above requirements
Take metal darts as an example. Metal darts are darts with sharp blades on the dart head. By throwing vigorously, the sharp blade penetrates the target without falling to judge the result. It is very easy to cause destructive damage during the flight of the dart, and this kind of target After using it many times, it cannot be used repeatedly because the dart has too many holes in the target

Embodiment 1

[0028] This embodiment provides a paper product printing color change process, such as figure 1 As shown, it includes the following steps:

[0029] Cut the paper according to the product design size to make a paper printing substrate;

[0030] offset printing an underlying image on the surface of the substrate;

[0031] Coating a transparent oil film on the surface of the underlying image;

[0032] Screen printing monochromatic color-changing ink layer on the surface of the transparent oil film;

[0033] Combined into a complete product according to product design requirements.

[0034] The function of the monochromatic color-changing ink layer is to cover the bottom image when it is not exposed to water, and to print various patterns on the pure surface layer according to product design requirements. is transparent, revealing the underlying image.

Embodiment 2

[0036] This embodiment provides a paper product printing color change process, such as figure 2 described, it includes the following steps:

[0037] Cut the paper according to the product design size to make a paper printing substrate;

[0038] offset printing an underlying image on the surface of the substrate;

[0039] Coating a transparent oil film on the surface of the underlying image;

[0040] Screen printing monochromatic color-changing ink layer on the surface of the transparent oil film;

[0041] Offset printing or silk screen surface image on the surface of the monochromatic color-changing ink layer: it may be to adopt monochromatic color-changing ink screen printing monochrome surface image on the surface of the monochromatic color-changing ink layer, or to adopt four-color color-changing ink silk screen color surface image; It is also possible to adopt monochrome ink offset printing monochrome surface image on the surface of the monochromatic color-changing ink...

Embodiment 3

[0044] This embodiment provides a color-changing paper printed matter made by the method described in Embodiment 1, such as image 3 shown, which includes:

[0045] Paper substrate 10, the underlying image 20 offset printed on the surface of the paper substrate 10, the transparent oil film 30 coated on the surface of the underlying image 20, and the monochromatic color-changing ink layer 40 silk-screened on the surface of the transparent oil film 30 .

[0046] The color-changing paper printed matter of this embodiment presents the white color (or other monochrome) of the color-changing ink layer 40 when it does not meet water, and when it meets water, the monochrome color-changing ink layer 40 absorbs water and becomes transparent, showing the underlying image 20 .

Abstract

The invention provides a paper printing color changing process which includes steps of cutting paper to make a printing base according to a product design size, offsetting a bottom image on the surface of the base, coating a transparent oil film on the surface of the bottom image, printing monochromatic color-changeable printing ink layer on the surface of the transparent oil film by means of silk screens, and combining to form a complete product according to requirement of product design. The invention further provides a color-changeable paper printed matter. Before the paper printed matter is wet, a white or surface image layer of the color-changeable printing ink layer is exposed; after the paper printed matter is wet, the color-changeable printing ink layer absorbs water and becomes transparent, the bottom image is exposed, and accordingly color changing effect is realized; after water is evaporated, the white or surface image layer of the color-changeable printing ink layer of the paper printed matter is exposed, and thus, the paper printed matter can be reused. In addition, as the paper base is low-cost, light and portable, the paper printed matter has good market prospect and high popularization value.

Description

technical field [0001] The invention relates to the technical field of paper printing, in particular to a printing method capable of making paper exhibit a color-changing effect and a color-changing paper printed matter. Background technique [0002] At present, it is usually plastic products that change the picture by changing the visual angle, and the similar effect cannot be achieved in paper printed matter. [0003] On the other hand, with the development of social economy, people have higher and higher requirements for entertainment or game types and effects. They need entertainment toys with novel effects, strong fun, good safety, low cost and sustainable use. Not many products meet the above requirements. Take metal darts as an example. Metal darts are darts with sharp blades on the dart head. By throwing vigorously, the sharp blade penetrates the target without falling to judge the result.
