Die-cut indentation is a special process in post-press processing. It is mainly based on design requirements to consider whether to apply. In this paper, the overall process flow of die-cutting and indentation is roughly introduced from several aspects including the definition of die-cut indentation, the plate of die-cut indentation, and the manufacturing process of die-cut indentation.
What is a die-cut indentation?
The die-cutting and indentation process is based on design requirements, so that the edges of the color prints become various shapes, or add special artistic effects to the prints, and achieve a certain use function. The process of punching and cutting the substrate into a certain shape with a steel knife (or engraving with a steel plate) is called die-cutting; the steel wire is used for imprinting to stamp marks on the substrate or The process of leaving a groove mark that facilitates bending is called an indentation process.
What is a die-cut indented plate?
The plate used for die cutting is actually a steel wire with a sharp edge. Its height is about 23.8 mm. The steel wire is bent on the jig into various desired shapes and then grouped into a “printing plateâ€. After imprinting, the substrate is cut into the desired shape. The plate for the indentation is also a steel wire, which is slightly lower (about 0.8 mm lower) than the cutting line used for die cutting. There is no sharp product, and the row is formed into a “printing plate†and is impressed with it to make marks on the surface of the substrate. There is a unique and seamless tool that is made of a single piece of steel, which is more costly but durable.
What are the bottom plates of die-cut indentation plates?
To make a die-cutting indentation plate, you must first make the bottom plate, then bend the cable according to the required knife shape, and discharge it in the bottom plate. The bottom plate has two kinds of metal bottom plate and wood plate bottom plate.
1 metal bottom plate. Metal bottom plate has lead empty typesetting, pouring lead plate, steel type engraving, steel engraving and so on. Lead empty typesetting is arranged in layouts using lead empty groups of various sizes. Cast lead plates are cast into a master plate with molten lead alloy solution. This method is to first bend the wire into the required shape, leaving a 10mm edge around it, and the outside is fixed with a wooden strip. The molten lead alloy is then poured into the mold and cooled to form a die cutter plate. Steel type engraving is to bend the steel strip into a curve closed frame similar to that of the die cut. The joint is welded firmly, and both sides are ground to a height of about 30 mm. Then, the frame of the cut figure is accurately planed, the knife edge is pulled out according to the line, and finally a heat treatment is performed to make a die cut plate. This kind of die-cutting is difficult to make and the process is more complicated. Steel plate engraving is generally used slightly larger than the printed image, 25mm thick steel plate, the need to process one side of the grinding process, and then coated with a photosensitive solution, turn the sun. The part of the knife-edge line that is required for the graphic is milled, and then the knife-edge is carved out and finally heat-treated. Although the die cutter version is expensive, it can be used repeatedly for a long period of time. It is generally suitable for small and complex shaped products. At present, lead-air layouts are used more often.
2 wood board bottom plate. There are several kinds of wood boards such as plywood, wood board, zinc wood nail board and so on. Plywood is generally 9 to 13 layers with a thickness of 18 to 20 mm. It transfers the design pattern to the plywood, drills the hole kerf at the line, and inserts the die cutting line and the indentation line into a die-cutting imprinting plate. The die-cutting quality of this method is higher, and the die-cut version is lighter in weight and shorter than the blank lead-row platemaking. The board bottom plate is a hard-wood board that is directly sawed and used as a base plate. Zinc wood nail board is to make the negative pattern on the zinc plate. The zinc plate is nailed to the wood board. After trimming, the steel knife can be mounted on the die cutting machine. Commonly used wood board is plywood.
What is the process of making a die-cut indentation?
The production of die-cutting indentation plate, commonly known as row knife. The so-called row knife refers to the steel knife, steel wire, lining empty materials according to the requirements of the spelling, forming a die-cutting indentation version of the process operation Currently, the domestic row knife operation basically uses two types of metal empty lead and plywood lining materials.
For a lining material made of a gluing plate, the base plate must be made first. The other operations are basically the same.
1 base plate production. Refers to the product design requirements, using a certain way, draw or draw the outline of the die on the floor, and then through different processes, according to the outline of the narrow slot sawing. In the production of the bottom plate, the drawing of the contour profile of the die and the quality of the saw seam are the key to the quality of the plate. The manufacture of the bottom plate was done by hand at first. The accuracy of the mold depends entirely on the individual's technical level. It is necessary to draw the pattern of the die on the plate by hand and use a wire saw to artificially sew along the pattern. Now lasers have appeared. The platemaking system, in this system, automates operations until the final process. In the operation, as long as the external dimensions and paper thickness of the product to be die-cut are input into the electronic computer, the electronic computer can control the substrate production system so that the substrate is in accordance with the die pattern. The laser beam moves automatically below.
2 steel knife (line) cutting and forming processing. The cutting and forming process of steel knives (lines) refers to the process of cutting die-cutting steel knives and steel wire into the largest forming line segments according to the design specifications and requirements, and then processing them into the required geometric shapes. . During the knife-type molding, the selection of steel blades and steel wires should be paid great attention. The hard steel blades have high mechanical strength and poor elasticity. They should be used as straight-row cutters and should not be bent too much. The soft steel cutters should be flexible enough to be bent. Large arc cutters. When selecting the steel knife or steel wire, factors such as the thickness of the die-cut product material and the width of the indentation line should also be considered. The general rule is: the thickness of the die-cut product is different, and the height and thickness of the steel wire should be different. With the decrease of the paper thickness, the height of the steel wire increases and the thickness decreases.
3 row knife. According to product design specifications and styling, after drawing a good specification and verifying with the printed artwork, the knife cutting operation can be started. According to the different liner materials used, the row knife operation is slightly different. The technical requirements and the process difficulty of the metal air lead cutter are generally slightly higher than that of the plywood lining material row knife. When using metal blank lead cutters, according to certain process requirements, the blank lead is directly fixed at the designated position of the molded plate to complete the row cutter operation, which is very similar to the typesetting operation in movable type printing. In the metal empty lead blade, the operator is required to be able to flexibly and correctly use a variety of liner materials, and the ejected plate cannot be loosened or cross-threaded in the die cutting process. Especially when arranging all kinds of geometric figures, it is necessary to ensure the specification of the figures and to ensure that the elasticity is appropriate. In the case of multiple editions of a single edition, they must be consistent with each other, and they cannot be different because of the different lead multiplication rates. In addition, after the knife is arranged into the plate, the vertical line of each point on the side should be equidistant, in order to facilitate clamping and fixing when the knife is fixed. In the operation of plywood lining material row knife, after the steel knife and steel wire are embedded in the floor saw seam, the gap should be perpendicular to the plane of the floor, and the clearance should be appropriate. The phenomenon of deformation or twisting during embedding or processing should not occur. If the layout is composed of a plurality of floor plates, the individual floor plates should be first lined up and shaped, and then be arranged one by one. Finally, the plates are uniformly clamped and fixed. After aligning the plates, the longitudinal and transverse lines should be at an angle of 90° with each other, and the edges must be parallel to each other so that the entire layout can be flattened. In addition, steel knives and steel wire joints should be discharged in a proper position, and the interface clearance should be appropriate. The phenomenon of overlap or excessive clearance cannot occur due to pressure.
4 Check and check the knife. Some of the fixed knives are called plate making or card printing, which is to install the plate in the plate. After completion of the row of knives, do a full inspection and verify that the knife can be officially started. Empty plate lead blanking materials for the plate solid knife, after the wood frame to be placed around the plate, with a solid plate lock directly fixed; plywood lined blank material for the diecut, should be based on the layout of the specific circumstances, After adding and placing the wooden bar, it is fastened by the solid plate clamp.
