A kind of manufacturing method of two-way see-through film

Abstract

The invention discloses a double-direction perspective film and a manufacturing method thereof. The double-direction perspective film successively comprises a transparent film, an adhesive layer, a metal layer and a pasting layer, wherein a photic zone is distributed on the metal layer, and the photic zone penetrates through the adhesive layer. The double-direction perspective film and the manufacturing method thereof provided by the invention have the advantages that a structure that the transparent film and the metal layer are mutually matched is adopted, the disadvantage of printing ink is fully made up through the strong covering power and color rendering of the metal layer, a problem of printing oil transfer after long-term storage is avoided as the metal layer has stable quality, and a picture has the strong metal feel due to the metal layer; meanwhile, the photic zone arranged on the metal layer can guarantee that the picture is distinctly showed, transmitting and perspective effects are met, an ink surface of the photic zone is also inked and colored, the picture printed on the front side is distinct, the picture of a mirror image is also seen from the reverse side, and the metal layer can realize a background layer with different colors on the two surfaces, which can not be realized by the printing ink; the double-direction perspective film and the manufacturing method thereof provided by the invention have the advantages that the structure is simple, the manufacture is convenient, and the pasting is convenient and firm.

Description

Technical field [0001] The invention relates to a see-through film for inkjet or printing, in particular to a method for manufacturing a two-way see-through film that is widely used in the fields of advertising, decoration and the like, and is especially suitable for being posted on a transparent board. Background technique [0002] The existing see-through film for printing inkjet or printing is usually composed of a transparent film, a color printing layer and a base paper. The color printing layer is arranged between the transparent film and the base paper, and is distributed on the color printing layer. In the light-transmitting area, and in order to facilitate the pasting, a self-adhesive layer is usually arranged between the color printing layer and the base paper. However, because the color printing layer is generally formed by printing ink on the transparent film, the quality of the color printing layer is unstable and cannot be stored for a long time before gluing, other...

Problems solved by technology

However, since the color-developing printing layer is generally formed by printing ink on the transparent film, the quality of the color-developing printing layer is not stable, and it cannot be stored for a long time before glue application, otherwise the ink will transfer to the transparent film , or the residual solvent of the ink destroys the printing surface of the transparent film, resulting in poor ink absorption performance, etc., and the hiding power and color rendering performance of the ink are poor, resulting in unsatisfactory display effect of the screen, and the use of ink to make color printing layer, which pollutes the environment and is not environmentally friendly, and the ink needs to be dried to form the required color printing layer, so the production efficiency is low

At the same time, if you want to get a color-developing printing layer with different colors on both sides, you must print two different colors of ink multiple times, but because the ink solvent of one color will penetrate into the ink of another color, different colors will be produced. Mixing effect, coupled with the weak hiding power of the ink, the final color printing layer obtained is a mixed color layer of two different colors, rather than the required double-sided layer of different colors; moreover, using two different colors of ink For two-color printing, the alignment is difficult to be accurate, and qualified products cannot be obtained at a reasonable cost from the production process; therefore, it is difficult to produce color-developing printing layers with different colors on both sides with ordinary ink, resulting in poor performance of the picture. Not ideal, the screen display effect is poor

If UV ink is used to print and produce, the cost will be high, and it is difficult to accurately align multiple printings, so it is also difficult to produce high-quality and moderately cost-effective see-through film products with different color rendering effects on both sides
