Abstract

The utility model relates to a printing lantern sheet for an advertising lamp box, which is composed of coloring material layers and a base sheet. The utility model is characterized in that the back surface of the transparent base sheet is covered by three coloring material layers. The coloring material layer which contacts the base sheet is a pattern layer, the coloring material layer in the middle is a background color layer, and the outermost coloring material layer is a color replenishing layer. The utility model has the advantages of high quality of the picture and easy production, and the pattern is not easy to scrape.

Description

The printing lamp sheet of advertising lamp box

The utility model relates to a kind of advertising lamp box that is used for, particularly the lamp sheet of printed patterns on transparency carrier.

Chinese patent 95242696.X number, name is called " the lamp sheet of two-sided overlapping printing ", discloses a kind of lamp sheet of lamp box advertisement, is made up of colorant layer and substrate, it is characterized in that the tow sides of transparent or semitransparent substrate all are coated with the colorant layer of same color.This scheme has solved the lamp sheet that only has single face colorant layer that (or enlargement of color photos) processing that in the past was printed on one side makes, and the shortcoming that the effect before and after the lamp can not be taken into account is beaten in existence.The lamp sheet had effect preferably for making dozen lamp back light sheet in the past, and picture often adopts supersaturation to handle.Because picture is hypersaturated state before playing lamp, when people viewed and emulated under daylight, the picture stereovision of being seen was very poor, or even a slice " is deceived "; Correspondingly, if want to improve the picture effect of beating before the lamp, the effect of then beating behind the lamp just seems thin, pale.This patent all is coated with the colorant layer of same color at the tow sides of substrate, has solved problem.Simultaneously, this scheme exists in the galley of positive and negative (front and back) two covers when making, the shortcoming that processed complex and difficulty are big.And, it must be in the printing of the front of substrate pattern, scratch pattern and become substandard products easily in the transportation and the process of installing is unfavorable for long-distance transport.

The purpose of this utility model provides and a kind ofly can both reach high-quality picture effect before and after the lamp beating, and be easy to produce, the printing lamp sheet of advertising lamp box that can not the scratch pattern.

The purpose of this utility model is to realize by following scheme: the printing lamp sheet of the utility model advertising lamp box is three layers of colorant layer that cover patterned layer, background color layer and complementary color layer at the back side of transparent substrate respectively.In the patterned layer of pasting substrate is the multicolour pattern layer of presenting advertising content, middle background color layer is the photic zone of one deck white, play the color that sets off patterned layer, one deck of outermost is and the color of patterned layer, pattern, complementary color layer that size is identical, plays the effect of beating behind the lamp the patterned layer complementary color.The colorant layer of this structure concentrates on the back side of substrate, only need during printing once cover galley print respectively twice passable, simplified production routine.

After the lamp sheet was dressed up lamp box, finished surface did not have the colorant layer, can the scratch pattern, and the yield rate height; Before playing lamp, people see normal clear picture true to nature under daylight; After playing lamp, because the pattern generating geometric ratio of two double exposures mutually is hyperchromic and the hyperchromic effect that filters, the picture saturation degree is adjusted, and makes people see same clear picture true to nature, and having reached all has high-quality picture effect before and after playing lamp.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1, the printing lamp sheet of the utility model advertising lamp box is three layers of colorant layer that cover patterned layer 2, background color layer 3 and complementary color layer 4 at the back side of transparent substrate 1 respectively.In the patterned layer 2 of pasting transparent substrate 1 is the multicolour pattern layer of presenting advertising content, middle background color layer 3 is photic zones of one deck white, play the color that sets off patterned layer, one deck of outermost is according to the color of patterned layer 2, pattern, size and fixed complementary color layer 4, plays the effect of beating behind the lamp patterned layer 2 complementary colors.

The printing lamp sheet of the utility model advertising lamp box, three layers of used colorant layer can adopt printing ink or coating printing, also can be with methods such as paster stickups and realize; Described transparent substrate is to use organic glass, also can be with clear glass or film.

Claims (2)

1, a kind of printing lamp sheet that is used for advertising lamp box is made up of colorant layer and transparent substrate, it is characterized in that the back side of transparent substrate is coated with the colorant layer of multilayer.

2, the printing lamp sheet of advertising lamp box according to claim 1, it is characterized in that the colorant layer that covers the transparent substrate back side is made up of three layers of colorant, at the one deck that is pasting transparent substrate is patterned layer, and middle one deck is the background color layer, and one deck of outermost is a complementary color layer.
