In Screen Printing Network design process, the first thing to consider is multiple colored dot net negative angle with the line, and also to consider the perspective of the film the Internet and wire line angle with the longitude and latitude. The aim is to minimize the size of tortoises, until the normal visual range of the true picture will not be interference effects. >> Sign card industry: all kinds of scenery Unlimited

But things are always divided into two. In Make Screen Printing 3D Signs Process, just to make use of above mentioned annoying moire and moire more obvious the better. The so-called three-dimensional signs, is the flat plate in a visually appealing to X, Y, Z of the three-dimensional feeling, that seems the Photo Has a strong three-dimensional feeling, and its graphic point of view with the observation of changes in deep Mobile Sense.

Now the basic structure of three-dimensional signs, basic principles and techniques of visual profile as follows:

First, the basic structure A certain thickness of transparent Sheet , Such as the transparent PC , PVC , Glass , Plexiglass Other sheet. In the bottom sheet printed on colored dot, and coated with a layer of good bottom reflective ink, such as silver ink or gold ink. Vacuum coating method can also be coated with high reflective of aluminum, to increase the contrast effect. Longer reflective Coating Coated with a layer of a certain hardness of the protective layer.

In the front sheet, using UV curable transparent resin, with a colored dot with the same bottom line number of the network for network printing. Its structure as shown.

Be emphasized that, transparent resin, colored dot dot line and bottom line, angle, moire performance should make clear enough, full. The point value of two networks can be measured film intertwined.

Second, visual theory Is any reason to sign on the three-dimensional graphics and a deep three-dimensional perspective with the observation of changes in the movement of a deep sense? The following three reasons.

1, a transparent film base has a certain thickness. As the colored dot pattern is printed on the film basal layer, and transparent resin film network is printed on the front of base, thereby between the two networks have some distance.

2, if the blade is not printed in the upper transparent resin outlets that printed color dot, two dot lines up and down with the proper angle, which makes it moire fully reflect concentration areas and sparse areas. At this point already has a three-dimensional feeling, when the angle changes observed when the two networks will re-mix of new-intensive areas, thus giving a feeling of movement. Dense area was a clear pattern later provided the necessary foundation. However, the overall effect still sparse areas moire interference, the pattern of significant degree and deep sense of not very obvious.

How to improve the degree and pattern of apparent deep sense? This is the key to making three-dimensional signs.

3, amplification using convex lens principle. As the film base of the front is transparent resin according to the appropriate screen angle screen printing of the network, the first network will be formed with the bottom of the colored moire-intensive areas; Second, a transparent resin, each network is a small convex lens. However, its diameter is too small, so the effective area of observation is very limited. In the tiny, quantitative observation range, the number of densely populated areas of the network and be amplified more observing, while the number of observation networks sparse areas and less, although the network the same magnification, but the dot pitch also will enlarge , observed in a very limited range, but even more sparse. At the same time as the top network is colorless and transparent, and lower the formation of colored dot moire without color stacking, played a certain play down the role, so that the density limits of network design is more obvious; Third, due to amplification of three-dimensional convex role, namely, X, Y, Z three directions of amplification, making even more intensive and far-reaching area network design; its four films based on the transparent resin throughout the network over the equivalent of the tiny lens, convex combination of extended observation range, was able to see the full design-intensive area network; its five in the observation angle change, the fact is constantly changing convex lens used to observe different locations, but also on the lower network reorganization process of network-intensive areas , resulting in the feeling of movement patterns.
