Five kinds of printing hot stamping processing methods
Commonly used post-press processes, such as foil stamping, embossing, dimensional foil stamping, UV and so on. These are the more commonly used post-printing processes when designing. About hot stamping, it should be called: hot electrochemical aluminium (Foil Stamping), because the most commonly used is gold, silver, so we commonly known as hot stamping, hot stamping, hot stamping gold foil and so on.
Foil stamping process of printed materials, we have seen, book covers, real estate albums, business cards, packaging, are grey like to use. But if it is not into the printing house, may not be too clear about the production process of the printing process.chocolate bundt cake box recipe

1.1, material: the material to be hot stamping, generally paper, or other materials such as plastic, wood, fabric and so on.
1.2, aluminium carbide: also known as hot stamping paper, gold foil paper. Aluminium carbide by the manufacturer to produce a variety of fixed colours, such as red, black, blue, purple, green, etc., the same colour system also has different effects, such as gold, matte gold, light gold, champagne gold, etc., there are also some special colours such as quicksand, laser gold, etc.;
1.3, hot stamping plate: we first need to design a good graphic engraving on the metal plate, through the metal plate on the graphic content embossed to the material to be hot stamping. General hot stamping plate materials are zinc plate, magnesium plate and copper plate.
2, hot stamping and stamping chocolate cake from box
We can first imagine a company stamping it: will be engraved with the name of the company’s seal, coated with sealing oil, hard cover to the paper.
Then, hot stamping can also be understood in this way: engraved hot stamping plate is the seal, the use of aluminium foil is the sealing oil, and force the gold foil cover to the paper, completed the whole process of hot stamping.
This way to understand the image of it.

1, see here, is not similar to stamping?
2, hot stamping version and the same as the seal, it is also necessary to mirror the contents of the carving, this way to cover / hot stamping on the paper will be positive;
3, too fine and too fine fonts are difficult to carve out on the seal, stamping version is the same, the fineness of the small letters can not reach the printing;
4, seal with radish and rubber engraving precision is different, hot stamping is the same, copper plate fine engraving and zinc plate corrosion precision is also different; box chocolate cake recipe
5, different strokes thickness, different special paper, the temperature and electrochemical aluminium material requirements are not the same, the designer does not have to care, the pot please to the printer, just know one thing: perverted details can be solved by perverted prices.
So, printing hot stamping, pre-press documents how to do hot stamping version?
First of all foil stamping file if you want good results, it is best to vector the file. Do the file when the content of the hot stamping and printing content into different layers; because the general content of the hot stamping is not printed, so that the printing plate is sent to the convenience and also good for others to see the location of the hot stamping. You can do the hot stamping version of the printed layer can be deleted, only to retain the content of the hot stamping can be, the rest can be handed over to the manufacturer of the hot stamping can be.
What is the difference between hot stamping, printing gold, special gold in the printing process? willy wonka and the chocolate factory box office
Foil stamping is a gold aluminium foil film embossed onto the paper by heat transfer, the highest gloss, smooth to the touch, texture, and will look like a mirror as particularly bright. The disadvantage is the high cost, slow production speed, usually not a large area to use.
Printing gold, as the name suggests, gold ink printed on paper above, gloss is not as high as foil stamping, touch and print the same, no special texture. Advantages are low cost, can be completed at the same time as printing, high efficiency.
Special gold, and printing gold, is the same, according to customer requirements of special modulation of gold, can be red gold, blue gold, various colours of gold. The cost is higher than the gold printing, other and gold printing process is the same. assorted box of chocolates
Generally will be used first printing after hot stamping way.
First stamping after printing process is to enhance the visual sense of the pattern after printing, first stamping and then four-colour printing on the stamping pattern is a process method. Generally use the dot overprinting gradient metallic luster of the colour pattern, has a better visual performance. In general, the first stamping and then printing process is divided into partial stamping full overprint, partial stamping partial overprint two kinds, the first is to enhance the printing pattern local metal sense, such as the border of the product or the pattern on the Logo logo, the second is in order to highlight the pattern in the hot stamping area of the metal effect, this design can not be achieved with the metal ink, and its not used to superimpose the printing dot. The first in the process to achieve the difficulty of printing products due to overprinting has higher requirements and has a certain degree of process difficulty.box chocolate cake recipes
The first hot process requirements: local first hot after printing process is the most important before and after the two processes of overprint accuracy and printing stability issues. Generally, the overprint error is not more than 0.5mm, but with the improvement of customer’s quality requirements, the overprint error of printing and hot stamping to the overprint error of the printing dots, the accuracy requirement is raised to the level of 0.1mm, which greatly enhances the process difficulty, in order to meet the requirements of overprint accuracy of the front and back two processes in the bulk printing, it puts forward a more stringent requirements on the materials, equipments, moulds, personnel, and so on.
In the process flow, we design the route is: die-cutting → hot stamping → four-colour printing → laminating. In the stamping before the design of a die-cutting border process, the purpose is to ensure the consistency of paper size, and die-cutting version of a corner into a small arc type, in order to distinguish between the paper gripper and pull the direction of the gauge, to prevent the release of the reverse. In the process to achieve, to be considered from the following 5 points. 1. material selection 2. hot stamping plate production 3. hot stamping equipment and pull the position of the points 4. measurement technology requirements 5. packaging and transport best chocolate box cake recipe
After printing process points: stamping finished semi-finished products for re-printing, due to stamping pattern edge is formed by the shear effect, there will be some slight residual aluminium electrochemical debris, which is what we call the phenomenon of burrs, with a magnifying glass to see more significant. In the printing, these residual gold will be anti-sticking in the blanket above, with the increase in the number of printing, anti-sticking aluminium carbide will be more and more in the blanket, and even form a circle of obvious graphics, resulting in the printing of the phenomenon of loss of network, so the printing needs to be empty before printing once again, to the aluminium carbide debris pressed off, or manually swept powder processing.
In the production process must be regularly cleaned rubber blanket, practice shows that 2000 sheets or so to clean a better effect; for the printing of the phenomenon of anti-pulling aluminium carbide, ink on the surface of aluminium carbide instant viscosity is greater than the adhesion of aluminium carbide on paper, the solution is to increase the ink in about 5% of the de-adhesive to reduce the viscosity of the ink, if the colour management permits, but also try to switch the order of the ink, will be weak viscosity of the Yellow ink on the first unit to print.
Foil stamping process is already a very common part of printed materials, and the technology is also very mature. The following for you to introduce the five kinds of hot stamping method, these five kinds of processing can be used in printing, and each has different characteristics, you can with different designs to choose different hot stamping method.
First, flat hot stamping
Flat stamping is the most commonly used stamping method, only the content to be stamped will have metal, other places for the white or printed content. The purpose of flat stamping is to highlight the location of stamping mainly, the most important information will be stamped with gold. Compared to other processes, such as reverse stamping and multiple foil stamping, flat foil stamping is less difficult and the chance of error is relatively low. In addition, because it is the simplest stamping process, the loss of paper will be less.
Second, reverse stamping
Reverse stamping for the opposite of flat stamping, with metal hollowing to highlight the position of the white space, the part of the stamping is used to set off. The usual practice will be to use a large graphic surrounded by the graphics to highlight, surrounded by the graphics will be hot stamping and to highlight the graphics on the hollow out, thus forming the effect of reverse stamping. When doing reverse stamping, if the area of gold foil lining is large, the price will be higher. And the line of the graphic to be highlighted can not be too thin (need more than 6pt), otherwise the effect of the finished product will be unsatisfactory. If the use of special paper stamping, you need to take into account the characteristics of the paper grain and so on, if the surface is not smooth paper, it is not very recommended to use reverse stamping, because the fineness of the large area stamping is easy to be affected by the effect of paper grain.
Third, printing and stamping overlap
Printing and hot stamping overlap is a very test of the master’s skills in the processing technology, its printing design is clever to combine the hot stamping and printing colours together. The master will first do the printing, and then while hot stamping, hot stamping process on the location of the higher degree of accuracy, but the effect of the finished product is first-class printing, playful. This practice is not only a test of the master’s skills, but also a test of the designer’s thinking about matching colours.

Four, multi-colour hot stamping
There are many designers in order to highlight the graphic, will be in the same graphic stamping twice or more, this we call multi-colour stamping. This stamping method also requires high precision stamping method, and printing and stamping overlap is similar, printing and stamping overlap is the colour and stamping, and multi-colour stamping is a variety of stamping colour overlap. When there are multiple colours to be processed for multiple stamping, attention needs to be paid to the location of the stamping and the compatibility of the gold foil. If the designer sets the distance between the two foils too short when designing, there will be a chance that the two colours will paste together.
Five。 Dimensional Stamping
The combination of hot stamping and embossing process is three-dimensional hot stamping, so that the part of the hot stamping is raised, and form a three-dimensional relief effect. However, it should be noted that the back of the three-dimensional stamping will have a concave effect, so remember to leave the reverse side of the design, otherwise the graphics or text will be affected.
