立体印刷在印刷行业的使用特点

在印刷领域,三维空间再现物体立体图像的印刷——立体印刷,已成为特种印刷行业中一个重要的内容。立体印刷原理就是模拟人两眼间距,从不同角度拍摄,将左、右像素记录在感光材料上,观看时,左眼看到左像素、右眼看到右像素,按照这一原理制作出的印刷品称为立体印刷。

In the field of printing, three-dimensional printing - stereoscopic printing - stereoscopic printing has become an important content in the special printing industry. The principle of stereography is to simulate the distance between two eyes, to shoot from different angles, to record the left and right pixels on the photosensitive material. When watching, the left eye can see the left pixel and the right eye see the right pixels. The printed product based on this principle is called stereoscopic printing.

体印刷具有如下特点:

Body printing has the following characteristics:

(1)能逼真地再现物体,具有很强的立体感。产品图像清晰、层次丰富、形象逼真、意境深邃;(2)立体印刷的原稿往往是造型设计或景物拍摄而成,而印刷品一般选择为优质的铜版纸和耐高温油墨印刷,所以光泽度好,颜色鲜艳,不易褪色;

(1) the object can be reproduced vividly, and it has a strong sense of stereoscopic. Product images are clear and rich, vivid and profound artistic conception; (2) the original three-dimensional printing is often design or scene filming, and print generally choose quality of coated paper and high temperature resistant printing ink, so good gloss, bright color, not easy to fade;

(3)印刷产品表面覆盖一层凹凸柱镜状光栅板,可以直接观看全景画面的立体效果。从人们对物体产生立体视觉上来说,对物体产生的立体视觉主要是从人的生理因素、经验和心理因素等方面而来的。<br />实际上,立体视觉是人在视觉过程中把上诉这些复杂因素综合在一起而形成的立体信息。从生理因素上来说,有视差(两眼视差和单眼运动视差)、辐辏、调节等。

(3) the surface of the printed product is covered with a concave convex column mirror gratings, which can directly watch the stereoscopic effect of the panoramic picture. From people's stereoscopic vision of objects, the stereoscopic vision of objects mainly comes from human's physiological factors, experience and psychological factors. <br: actually, stereo vision is in the process of the visual appeal of these complex factors and the formation of three-dimensional information together. From the physiological factors, there is disparity (monocular binocular parallax and motion parallax), convergence and adjustment.

具体地说,两眼视差是人们获得立体视觉的根本因素,就是在日常生活中,人们观察物体时由于两眼间的视角等原因,左右两眼所看到的物体图像就会产生差异,即视差,它给予人们立体感。

Specifically, parallax is the fundamental factor for people to obtain stereo vision, is in daily life, people see objects because of interocular differences, perspective and other reasons, the image of the object will be around the eyes see the appearance of parallax, it gives people a sense of stereo.

立体图像的效果必须由显示技术来体现。这里所说的立体显示是指对图像三维空间的立体信息进行再现,这是获得立体视觉的又一基本条件。实现立体显示主要有两种方法,即两向显示法和多向显示法。

The effect of the stereoscopic image must be reflected by the display technology. The stereoscopic display described here refers to the reproduction of three-dimensional information of the image, which is another basic condition for obtaining stereoscopic vision. There are two main methods to realize stereoscopic display, namely, two direction display method and multi direction display method.

(1)两向显示法。可分为立体镜法、双色滤色片法、偏光滤色镜法及交替分割法。无论采取哪种方法,都是利用两眼视差左右眼分别观察图像而获得立体视觉的。

(1) the two direction display method. Can be divided into stereoscopic method, color filter method, polarizing filter method and alternate segmentation method. No matter which method is taken, the stereovision is obtained by observing the images by the left and right eyes of two eyes.

立体镜法:立体镜法的基本原理是使用立体镜来观察左、右的图形而形成的立体感。这种方法自19世纪出现以来一直被广泛采用,但必须使用特殊的立体镜,否则就没有立体视觉。双色滤色片法:将左、右图像分别用红、蓝油墨印刷在同一平面内,通过红、蓝滤色片观察印刷图像的方法。由于滤色片与油墨互为补色关系,所以通过滤色片观察的图像不是红色和蓝色而是黑色。因此,这种方法仅限于黑白照片,不适于彩色印刷物。再加上不同波长的光分别进入两眼,容易使眼疲劳。所以,这种方法除了制作航空地图使用外,一般很少使用。偏光滤色镜法:将左、右图像分别通过相互直交的偏光滤色镜投影在同一平面上,左、右眼也用同样的偏光滤色镜进行观察。

Stereoscopy: the basic principle of stereoscopy is to use stereoscopy to observe the stereoscopic sense of the left and right graphics. This method has been widely used since its emergence in nineteenth Century, but special stereoscopic lenses must be used, otherwise there is no stereoscopic vision. Double color filter method: the left and right images are printed in the same plane with red and blue ink, respectively, and the method of observing the printed images by red and blue filters. Because of color and ink complementary color, so the image is not observed by color red and blue instead of black. Therefore, this method is limited to black and white photographs and is not suitable for color printing. Adding different wavelengths of light into the eyes, it is easy to make eye fatigue. Therefore, this method is rarely used in addition to the use of Aeronautical maps. polarizing filter method: the left and right image respectively through the polarizing filter mutually orthogonal projection on the same plane, the left and right eyes were also observed by polarizing filters of the same.

这种方法虽然需要专用眼镜,但是在立体电影和立体电视中已得到广泛应用。交替分割法:将左、右图像交替呈现在同一平面上并将同期不必要的部分进行遮蔽,从而产生立体感。由于残像效果会引起闪光,遮蔽用的眼镜价格较高,所以,这种方法至今未能普及。

Although this method requires special glasses, it has been widely used in stereoscopic films and stereoscopic TV. Alternate segmentation: the left and right images are presented on the same plane alternately and the unnecessary parts of the same period are shaded to create a three-dimensional sense. This method has not been popularized so far because the effect of the residual image will cause the flash and the price of the glasses is high.

(2)多向显示法。主要有视差屏蔽法和柱面透镜法。视差屏蔽法:视差屏蔽法也称视差狭缝法,是由F.E.Lves于1930年发明的,其工作原理是将左眼图像和右眼图像由狭缝进行分割并在软片上曝光,然后进行显影、晒版和印刷。若将其放置在摄影时相同的位置,两眼也分别置于放置图像的位置,就可看到立体图像。应用视差狭缝法,若将两个图像进行合成,就能得到视差立体图像。如果降低狭缝的开口比,可完成多个图像的合成,就可获得视差全景图像。

(2) multidirectional display method. There are mainly parallax shielding methods and cylindrical lens method. Parallax masking method: parallax shielding method, also called parallax slit method, was invented by F.E.Lves in 1930. Its working principle is to segment the left eye image and right eye image by slit and expose it on the film, then develop, print and print. If it is placed in the same position at the time of photography, the two eyes are placed in the position of the image, and the stereoscopic image can be seen. Using the parallax slit method, if two images are synthesized, the parallax stereoscopic image can be obtained. If the opening ratio of the slit is reduced, a number of images can be synthesized and a parallax panoramic image can be obtained.
