First of all, I would like to ask you a question. Whether you are a designer or a customer, when you see the design of product packaging, do you see a very beautiful design, but when the packaging material is presented in front of your eyes, there is a big gap in the bottom of your heart?
Do you know why there is such a big gap between physical objects and effect maps?
Come and tell you the secret.
The design process is not perfectly connected with the actual production, which may be that the designer does not understand the process, or packaging materials and processes are not well selected, or that the implementation of the printing process in the later production is not in place.
Let me give you a very common example:
We often see bronzing process in product packaging. Sometimes designer designs are very delicate, but it does not take into account that in the later production of bronzing, because the content gap is too small, resulting in the pattern burned out. In addition, the gold stamping font is too small, and the space between strokes is very small, which causes the font to be pasted out.
Above, you can see some characters with more strokes and smaller fonts, which have been pasted out, resulting in poor recognition.
Therefore, a good-looking product packaging, not only to design good-looking, but also to consider the application of later production. The combination of the two guarantees the final effect.
It looks like a simple package, but there is a lot of knowledge in it.
A package from design to proofing, and then mass production, the relationship between the several can be said to be closely linked. So when a package design draft comes out, the designer should have a physical printing process in mind after the final effect.
Next, we will talk about some of the knowledge in the printing process after the design draft comes out. Because Gu Xiaoyi Company mainly focuses on the design of the liquor industry, it is basically some printing and technology that is used more in the liquor industry.
A product packaging can be said to use a lot of processes, such as printing, gluing, stamping, bumping, embossing, UV, grinding, freezing point, flocking, die cutting, automotive lines and so on. And each process has different details.
Today I'd like to talk with you about the well-known bronzing process.
The scientific name of bronzing is hot press transfer printing, referred to as hot transfer printing. The principle is that the heated metal plate is pressed on the gold foil, and the heat makes the color layer of the gold foil adhere to the product. We often say that gold stamping and silver stamping belong to gold stamping, but the color of gold foil is different.
In the practical application of bronzing process, the choice of metal plate, gold foil, paper and bronzing form directly affects the final bronzing effect. Here we will focus on some forms of bronzing.
Hot stamping before printing
First ironing, then printing, then bronzing, and then printing on the printing press. First ironing and then printing can ensure the perfect presentation of some small details, to avoid the pattern because the space is too small ironing paste. It should be noted that the area of stamping is larger than the actual area to avoid offset of printing set.
The horse above is the effect of hot stamping and then printing. The main element of the horse is hot stamping elegant gold first, and then printing color. Finally, we also grind the main graphics to give people a delicate feel.
The surface of hot-stamped gold, i.e. hot-stamped gold, presents different patterns and shapes, which enriches the forms of hot-stamping and makes the packaging more delicate. (However, texture gold should pay attention to the size of the texture.)
The wine label above shows the golden part in the form of textured gold, and presents the pattern perfectly.
The Golden Strip in the middle of the picture above uses the form of texture gold to distinguish ordinary bronzing and make the whole picture more detailed.
The rose petal part of the above image uses texture gold combined with convex effect to make the petal a bright spot and eye-catching.
Multiple bronzing means repeated bronzing more than twice in the same graphic area. It is generally not recommended to burn too many times, which will lead to increased costs.
The above image is first blackened gold, then elegant gold, and combines texture gold and protruding technology to give a delicate and delicate feeling.
Firstly, blacken gold and then blanched gold, combined with texture and convex processing.
Stereo relief ironing
Stereo relief stamping is the combination of stamping and embossing technology. Stereo relief stamping realizes the simultaneous completion of stamping and embossing technology, reduces the production process and improves the production efficiency. It is more exquisite and beautiful than ordinary bronzing.
The main pattern part is treated by three-dimensional relief ironing technology, which gives people a sense of three-dimensional space as a whole.
Usually we use the most hot stamping, the surface of hot stamping is very flat.
Gold part bronze gold, silver hot dumb silver.
The main picture is made of elegant gold and blue gold.
The effect of burning gold on the top label logo and the bottom pattern.
Above is a part of the bronzing application example of 古一 finishing. If you have more different bronzing process, you can leave a message to communicate with each other.
Gold stamping is now widely used in various printing and packaging fields. Gold stamping is also the only printing technology that produces bright, non-discoloring metallic effects on paper, plastics, cardboard, and other printed surfaces.
For today's knowledge points, have you learnt anything useful? In fact, i wants to ask if anyone thinks that hot stamping is real gold? :)
