Abstract
The invention discloses a method for designing and manufacturing a three-dimensional microstructure hot stamping plate, which comprises the following steps: s1, composing the image information plane, the image entity forms the structure with shape containing relation. S2 uses the outermost layer of graphics and text having inclusion relation as the first base layer information, i.e. the main base surface of the stamping surface. S3 dividing the other graphics information except the basic layer into multiple presentation layers, taking other presentation layers with inclusion relation as secondary basic surface, and processing the divided presentation layers with a concave or convex 0.05-0.3 mm. Other inclusively related performance layers are also treated with 0.05-0.3 mm that are concave or convex relative to the secondary base surface. Forming a multilayer three-dimensional microstructure of a primary base layer, a secondary base layer and a performance layer. And S4, generating a tool path file according to the computer aided design, and engraving the tool path file into a gold stamping plate or a steel stamping plate by using a high-precision engraving machine. Compared with the traditional gilding plate steel seal plate, the design and manufacturing scheme adopted by the invention increases the fineness and the stereoscopic impression in multiple, and greatly improves the applicability and the imitation difficulty.
Description
Technical Field
The invention belongs to the field of design and manufacture of a hot stamping embossing plate, relates to the field of printing, and particularly relates to a design and manufacture method of a three-dimensional microstructure hot stamping embossing plate.
Background
The traditional hot stamping and impressing technology is commonly called as a concave-convex or steel stamping or gold stamping technology, and has the defects of unclear fine characters, poor small-area image-text effect, single information layer and the like. Although the relief gold stamping concave-convex process and the refraction hot stamping impression process can partially solve the problems of stereoscopic impression and definition, the process has the defect of easy imitation, so that the anti-counterfeiting mark is easy to imitate, and the market updating requirement is far beyond the reach.
Disclosure of Invention
The method aims to solve the problems that the image-text definition is not enough and the information is mainly represented in a single plane layer in the traditional hot stamping and impressing method. The invention provides a design and manufacturing method of a three-dimensional microstructure hot stamping embossing plate, which realizes that clear three-dimensional multilayer information images and texts with micron-level fineness are manufactured on the surface of paper by hot stamping and embossing the image and text information in a one-step way by layering and engraving and micro-engraving into a corresponding hot stamping embossing plate, and hot stamping and embossing molds are difficult to re-engrave according to the complexity of design even if the effect is real, thereby achieving the aim of visual anti-counterfeiting of the public. Because the hot stamping and impressing mould has strong durability, the general brass fine engraving plate can achieve more than ten thousands of times of printing, and has huge economic advantages in cost compared with other anti-counterfeiting technologies.
The design and manufacturing scheme of the three-dimensional microstructure hot stamping plate is as follows:
s1, first, typesetting the image-text information plane, forming a structure with appearance containing relationship on the entity graph, wherein one entity graph is a presentation surface which is a horizontal surface, forming a presentation layer by concave-convex processing, and the presentation layer is a three-dimensional surface;
s2, using the outermost layer of graphics and texts with inclusion relation as first basic information, namely the main basic surface of the hot stamping and stamping surface;
s3, other image-text information except the basic layer can take other representation surfaces with appearance containing relationship as a secondary basic layer, other image-text entity appearances without containing relationship are directly taken as the representation surfaces, the divided representation surfaces are processed with 0.05-0.3 mm of concave or convex relative to the primary basic surface, other representation layers with containing relationship are processed with 0.05-0.3 mm of concave or convex relative to the secondary basic surface, and a multilayer three-dimensional microstructure of the primary basic layer, the secondary basic layer and the representation layers is formed;
and S4, generating a tool path file according to the computer aided design, and engraving the tool path file into a gold stamping plate or a steel stamping plate by using a high-precision engraving machine.
Preferably, a proper expression layer can be added to the conventional engraving design method and the local refraction line light shade line design, so that higher anti-counterfeiting characteristic can be embodied.
Preferably, the concave or convex expression surface can be designed in one hot stamping plate through different expression layers, so that the traditional process can not be expressed through multiple hot stamping and impressing.
Preferably, for some line patterns, the processing of micrometer-scale variation of line width can be performed to improve the imitation difficulty.
Preferably, the cutting tool engraving machine is selected to manufacture under the condition of reliable precision, the cost is lower, and laser engraving can also be manufactured.
Preferably, the method can be used as a single template, and can be used for manufacturing micron-level fine clear three-dimensional multilayer information pictures and texts by hot stamping and imprinting on the surface of paper at one time. Can also be matched with a resin male die for use, and has more obvious effect.
The invention has the beneficial effects that:
the invention is a new scheme, has certain universality, and can be widely applied to the fields of document certificates and product packaging and printing;
2 the invention has certain anti-counterfeiting characteristic, can meet the public visual anti-counterfeiting requirement according to the meticulous complexity of the picture and text, namely the reproducibility is very difficult;
3, the invention can produce clear three-dimensional multilayer information graphics and texts with micron-level fineness at one time, and the definition and the effect are obviously improved compared with the traditional method;
4 the invention is also particularly economical, has no great cost change compared with the traditional method and other anti-counterfeiting technologies, but the effect is greatly improved.
