本發明涉及光學膜技術領域,具體涉及一種光學凹凸紋路疊加膜。 The invention relates to the technical field of optical films, in particular to an optical concave-convex texture superimposed film.
現有的平面印刷品有二維圖像和三維圖像,二維圖像的印刷品比較成熟,但是二維圖像的印刷品的僅限於二維效果,故而,二維圖像的印刷品的圖像效果具有一定的局限性。而現有的三維圖像印刷品一般是採用一種凹凸膜產生三維效果,產生的視覺效果也不盡人意,給人以刺眼、不柔和及暈眩的感覺。 Existing flat prints include two-dimensional images and three-dimensional images. The prints of two-dimensional images are relatively mature, but the prints of two-dimensional images are limited to two-dimensional effects. Therefore, the image effect of two-dimensional image prints has Certain limitations. And existing three-dimensional image print generally adopts a kind of concave-convex film to produce three-dimensional effect, and the visual effect produced is also unsatisfactory, gives the feeling of dazzling, not soft and dizzy.

本發明還提供了第二種光學凹凸紋路疊加膜,其採用的技術方案如下:一種光學凹凸紋路疊加膜,包括第三片材,所述第三片材包括依次疊設無規則多方向折射的第一光學凹凸紋路層和單向聚光放大的第二光學凹凸紋路層。 The present invention also provides a second optical concave-convex texture superimposed film, which adopts the following technical scheme: an optical concave-convex texture superimposed film, which includes a third sheet, and the third sheet includes sequentially stacked irregular multi-directional refraction The first optical concave-convex texture layer and the second optical concave-convex texture layer for unidirectional light focusing and amplification.
本發明第一片材中的第一光學凹凸紋路層具有細密且不規則的凹凸紋路,可將透過的光朝多個方向發散,產生無規則多方向折射的效果。而第二片材中的第二光學凹凸紋路層所具有的凹凸紋路與第一光學凹凸紋路層的不同,其具有單向聚光放大的作用和效果,即,經第二片材中第二光學凹凸紋路層折射的光僅會朝單一方向發散,第二片材中的第二光學凹凸紋路層具有放大聚光的作用。通過第一片材和第二片材的疊加,能夠產生絢麗、立體的視覺效果。 The first optical concave-convex texture layer in the first sheet of the present invention has fine and irregular concave-convex textures, which can diverge transmitted light in multiple directions and produce the effect of random multi-directional refraction. The second optical concave-convex texture layer in the second sheet has a concave-convex texture different from that of the first optical concave-convex texture layer, which has the effect and effect of unidirectional light focusing and amplification, that is, through the second The light refracted by the optical concave-convex texture layer will only diverge in a single direction, and the second optical concave-convex texture layer in the second sheet has the function of amplifying and concentrating light. The superposition of the first sheet and the second sheet can produce gorgeous and three-dimensional visual effects.
第一片材和第二片材都可以採用透明或半透明的膜,在使用中兩者可以相互組合,以達到不同光感強度的視覺效果。如:組合模式一為透明的第一片材和透明的第二片材;組合模式二為透明的第一片材和半透明的第二片材;組合模式三為半透明的第一片材和透明的第二片材;組合模式四為半透明的第一片材和半透明的第二片材。
Both the first sheet and the second sheet can use transparent or translucent films, and the two can be combined with each other in use to achieve visual effects with different light intensity. For example:
同時,因第二片材的第二光學凹凸紋路層為單方向折射,當採用多張疊加時,不同的第二光學凹凸紋路層可具有相同或不同的預設折射角度, 使得對承印產品的不同角度產生不同立體視覺感,極大豐富了對承印產品的包裝視覺效果。 At the same time, because the second optical concave-convex texture layer of the second sheet is refracted in one direction, when multiple sheets are stacked, different second optical concave-convex texture layers can have the same or different preset refraction angles, It makes different three-dimensional visual senses for different angles of printed products, which greatly enriches the packaging visual effect of printed products.
本發明公開的第二種光學凹凸紋路疊加膜,在具備第一種光學凹凸紋路疊加膜主要優點的同時,相對於第一種光學凹凸紋路疊加膜,能夠節省片材的數量,節省了原材料;也減少第一片材和第二片材貼合的工序,故減少了工作量。而第一種光學凹凸紋路疊加膜比第二種光學凹凸紋路疊加膜具有多張第二片材的實施方式,因而,第一種光學凹凸紋路疊加膜的組合方式會更多。 The second optical concave-convex texture superimposed film disclosed by the present invention not only has the main advantages of the first optical concave-convex texture superimposed film, but also can save the number of sheets and raw materials compared with the first optical concave-convex texture superimposed film; It also reduces the process of laminating the first sheet and the second sheet, so the workload is reduced. However, the first optical concave-convex texture superimposed film has more second sheets than the second optical concave-convex texture superimposed film, so the combination of the first optical concave-convex texture superimposed film will be more.

本實施例的光學凹凸紋路疊加膜的成像效果原理為:第一片材1中的第一光學凹凸紋路層12透光的光線是往多個方向折射的,折射出來的光有點類似於漫反射產生的光,其沒有固定的方向,會朝多個方向發散。而第二片材2中的第二光學凹凸紋路層22具有單向聚光放大的效果,經第二片材2中第二光學凹凸紋路層22折射的光僅會朝單一方向發散,第二片材2中的第二光學凹凸紋路層22具有放大聚光的作用。通過第一片材1和第二片材2的疊加,能夠產生絢麗、立體的視覺效果。第一片材1和第二片材2都可以採用透明或半透明的膜,兩者可以相互組合,如:組合模式一為透明的第一片材1和透明的第二片材2;組合模式二為透明的第一片材1和半透明的第二片材2;組合模式三為半透明的第一片材1和透明的第二片材2;組合模式四為半透明的第一片材1和半透明的第
二片材2。第一片材1的數量為一,如果第一片材1的數量過多,則有可能會遮擋住光線;因第二片材2的第二光學凹凸紋路層22為單方向折射,採用多張時,也不易遮擋住光線,因而第二片材2的數量可以為多張,第二片材2採用多張時,各第二片材2的種類可以相同,可以不同,即,不同第二片材2的第二光學凹凸紋路層22具有相同或不同的預設折射角度。只要各第二片材2都具有放大聚光的效果即可。預設折射角度是指透過第二片材2時,其輸入光和輸出光之間的夾角。而且採用不同數量或不同種類的第二片材2和一張第一片材1結合可以產生不同的視覺效果。較為優選的方案是,在一般的情況下,第二片材2的數量採用一張即可。
The principle of the imaging effect of the optical concave-convex texture superimposed film of this embodiment is: the light transmitted through the first optical concave-convex texture layer 12 in the
通過第一片材1和第二片材2的疊加,第一片材1能夠改變第二片材2的反射方向,使承印所述光學凹凸紋路疊加膜的產品看起來沒有暈眩感和刺眼感,使視覺效果更加柔和,並可提升立體效果;同時,第一片材1和第二片材2組合形式多種多樣,能夠應用於如印刷、包裝、人造皮革等領域,適用範圍廣泛。
