Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1 to fig. 3, in a preferred embodiment, the utility model discloses a diffusion barrier printing ink silk screen printing structure mainly includes diffusion barrier body 1, and diffusion barrier body 1 is rounded rectangle, and it adopts the PET material to make for revise the diffusion angle of light in the structure of being shaded, make the increase of light radiation area.

The surface of the diffusion film body 1 is provided with an ink structure 2, and the ink structure 2 can be printed on the surface of the diffusion film body 1 in a silk-screen printing mode and cured through heat curing or UV (ultraviolet). Printing ink structure 2 includes white printing ink layer 3 and black printing ink layer 4, and wherein, white printing ink layer 3 adopts white or transparent printing ink silk screen printing to form, and black printing ink layer 3 adopts black printing ink silk screen printing to form, and the silk screen printing thickness on white printing ink layer 3 and black printing ink layer 4 is preferred 0.004mm ~0.06mm, and above-mentioned white printing ink, transparent printing ink and black printing ink adopt current optical printing ink can.

White printing ink layer 3 is located between diffusion film body 1 and black printing ink layer 4, and the outer edge of white printing ink layer 3 flushes with the edge of diffusion film body 1, and the outer edge of black printing ink layer 4 is located the inboard of white printing ink layer 3, and the outer horizontal distance along 1 edge apart from diffusion film body of black printing ink layer 4 is greater than the outer horizontal distance along 1 edge apart from diffusion film body of white printing ink layer 3 promptly. This structure can guarantee the light transmissivity on white printing ink layer 3, avoids black printing ink to shelter from light to improve the whole luminance of structure in a poor light. In addition, even if the white ink layer 3 enters the visual area due to the precision difference, no obvious black edge is generated, and the appearance of a user is not influenced.
