Embodiment 1
[0029] This embodiment provides a gradient screen printing anti-counterfeiting product, the gradient screen printing security product includes a printing carrier and a printing layer printed on the printing carrier, the printing layer is a printing screen, and the printing screen is composed of multiple Consists of vector lines with continuous gradient.
[0030] A vector diagram, also known as an object-oriented image or a drawing image, is defined mathematically as a series of points connected by lines. Graphical elements in vector files are called objects. Each object is a self-contained entity with attributes such as color, shape, outline, size, and screen position. Vector graphics draw graphics according to geometric characteristics. Vectors can be a point or a line. Vector graphics can only be generated by software, and the internal space of the file is small, because this type of image file contains independent separate images, which can be freely and freely Restricted...
Embodiment 2
[0034] Such as Figure 1-4 As shown, the continuous gradient includes one or more of graphic gradients (including thickness and straightness), grayscale gradients (256 colors in gray scale) and full-color gradients, and the graphic gradients include curvature gradients and / or thickness gradients . Take the graphic gradient function as an example, such as a straight line, the gradient becomes a curve, and the curve can change according to the designer's requirements. During operation, a straight line and a curve can be generated in the coreldraw software and connected together, and then use the gradient The function realizes the level of gradual change. If the level is less, the change will be faster and rougher. The more the level is, the change will be more delicate, and the anti-counterfeiting effect of the net pattern will be better.
Embodiment 3
[0036] The anti-counterfeiting effect of this embodiment on the printing layer, the printing layer also includes miniature fonts printed on the printing carrier, the miniature fonts are provided with anti-counterfeiting points, and the anti-counterfeiting points can be points that existing miniature fonts do not have, for example Figure 5 Set anti-counterfeiting points at the joints or ends of the strokes. The anti-counterfeiting points are usually difficult to identify with the naked eye. Only when they are enlarged to a certain extent can they be distinguished from the font. Bitmaps often cannot replicate the above-mentioned anti-counterfeiting points, and the anti-counterfeiting effect is good. Miniature font design, the effect of the change can only be seen when it is magnified 20 times, and it can be verified by overlapping with the original negative to find out whether it is true or false, so as to achieve the anti-counterfeiting effect.
