Hot foil stamping is a kind of printing technology.
Samples can be done by this machine.
Foil stamping refers to the temperature and pressure of the anodized foil hot stamping to the substrate surface of the process.
Anodized hot stamping graphics and text present a strong metallic luster, bright colors, and eye-catching, never fade. In particular, gold and silver anodized aluminum, with its magnificent, exquisite, and elegant decoration embellished the surface of the printed matter. Enhanced the artistic quality of the printed matter, played a prominent theme of Publicity Effect; Its brightness greatly surpassed the printing of gold and silver, so that the product has a high-grade feeling and give people the enjoyment of the United States. Meanwhile, due to the excellent physical and chemical properties of anodized materials, it plays a role in protecting printed materials, so bronzing technology is widely used in high-grade and exquisite packaging and decoration trademarks, calendars, book covers, and other printed materials;
Secondly, anodized hot stamping covers a wide range, from general book covers, trademark patterns, advertising, plastic products to daily department stores, from paper to leather, cotton cloth, etc. The workpiece can be packed and transported immediately after bronzing. Therefore, foil stamping technology is widely used. The hot stamping application is still expanding.
A screen printing machine is a machine that prints words and patterns on flat or regular surfaces. The basic principle of its work is: First of all, install screen printing plate (using the photographic plate-making method to make the screen holes on the screen printing plate as through holes instead of blocking the screen holes on the picture and text parts). Printing through the Squeegee, so that the ink through the pattern part of the mesh transfer substrate, the same graphics, and text as the original.
Silk Screen Printing is widely used in printing and dyeing, electronics, applied arts, commercial decoration, ceramic decoration, publishing, and printing industries.
It is widely used for graphic or flat surface printing patterns such as Cups, electronic products, cosmetics bottles, street, penholder, toys, mineral water bottles, shampoo bottles, etc.
Three elements of hot foil stamping technology
1.Time (T), 2. temperature (T), 3. pressure (P)
These three elements are interrelated and mutually binding. As we all know, the bronzing paper needs to absorb a certain amount of heat energy (Q) under certain pressure, can make stamping paper ink and additives to a certain shape hot stamping to the surface of products
Where the Q and P in certain external conditions are inversely proportional. That is, in stamping a product, if the bronzing paper in a bronzing position can absorb a lot of heat, this bronzing requires very little pressure to iron the product well
And the relationship between T.T. and Q. is:
Q = r * t (T-t 0)(R is constant and t O is room temperature)
So t and t are inversely proportional to, under certain external conditions, under certain pressure, to iron a good product, if you use a very short pressure time, then the hot stamping temperature must be set very high; if you use hot stamping temperature low, its bronzing pressurization time is set very long.
To foil-stamping a good product to have the following conditions:
1. Have a good hot foil stamping machine
A. General stamping machine consists of five parts: working part, debugging part, mooring part, Airway part, and electrical control part
B. A good foil stamping machine has five parts, reasonable design, compact structure, good performance, and long service life
2. Choose the right gilding paper
A. Bronzing paper has four layers: P paper base layer, ink layer, aluminum powder layer, hot-sensing pressure melts layer
B. The drawing of each layer of bronzing paper:
P-BASE is the basis of ink adhesion, using p-high strength and high toughness, enough to ensure the stability and continuity of bronzing paper
Ink Layer is to achieve the bronzing color
Aluminum powder layer is aluminum powder vacuum plating to bronzing paper, increase the brightness of bronzing products
