Thermal color-changing cups change color when the temperature is above 40℃, and cold color-changing cups change color when the temperature is below 20℃, which has not been popularized so far. Their principle is to print temperature-sensitive materials on the cup body. The materials used are heat-sensitive materials, which can resist high temperature of 320℃, are nontoxic, lead-free and chromium-free, and can reach European standards. According to the design scheme of the design draft, film, plate making, printing, drying, baking and then packaging.
There are basically three methods to process a cup into a color-changing cup: direct printing, water transfer printing and thermal transfer printing.
1, print directly:
It refers to printing directly on a cup with a roller printer. This technology is technically difficult. General factories can only print one or three colors. If overprinter is in high demand, they can't help it. However, powerful factories can overprint as many as 20 colors without leaving their positions. This technology is only suitable for small batch production and has low efficiency. Only color patches can be printed, so it is difficult to print photos.
2. Water transfer printing:
First, printing on water transfer printing paper with a printing machine can produce rich colors or mass production. However, the requirements for the environment are relatively high, and the printing environment is required to be constant temperature and humidity, so as to ensure the printing accuracy. Put the printed water transfer printing paper into water, separate the pattern from the paper, and transfer the pattern to a cup to bake the finished product. The following Christmas color changing cups belong to this kind of craft.
3, thermal transfer:
Basically the same as the printing process of water transfer printing, the printed heat transfer paper is transferred to the cup by machine heating and pressure. When water transfer printing is used to produce color-changing cups, all patterns are transferred manually, while thermal transfer printing is automatically processed by machines. Therefore, the modern color-changing cup factory with color-changing pigment production line, automatic printing production line and automatic thermal transfer decal paper production line is the embodiment of the strongest competitive strength.
Extended data:
The origin of the color-changing cup:
Everyone has the experience of being burned while drinking water, and a fast food company even paid a high compensation for customers being burned. Although many hot drinks cups in fast food restaurants are marked with reminders, the sales staff still take pains to remind every customer.
Of course, if the wall of the cup is not too thick, you can know if the drink inside is drinkable by touching it with your hand. However, if the cup wall is thin and the cup is not insulated, it will be very inconvenient to carry. This contradiction is particularly obvious in restaurants that provide take-away coffee service.
Finally, an inventor thought of inventing a "smart" cover, which itself is brown. When the beverage in the cup is hot and steaming, the lid will turn bright red, and when the temperature drops, it will turn brown again. So that customers can know at a glance whether the temperature of the beverage in the cup is suitable for drinking.
Nicholas grew up in a coffee shop run by his father. In the past 15 years, he has run many coffee shops himself. In his work, he found that there are two reasons why customers get burned by coffee. First, they underestimated the temperature of the coffee, and second, the lid of the coffee cup was not properly covered, which might cause serious burns. Perhaps Nicholas was not the first person to start thinking about this problem, but he realized that it would be a very broad market.
Later, a color-changing material caught Nicholas's attention, and he found that the cover with this color-changing function could solve these two problems well. The cup should be completely sealed when the lid is closed. Once the position is wrong, steam will run out of the gap, and the color of the cover at this position will change accordingly.
However, it is not easy to apply this material to the lid of the cup. Nicholas spent four years developing this magical lid. The manufacturing company Matsui has never produced such a thin product before.
This color-changing sleeve has been put into production and has been licensed in Australia and Asia-Pacific region, and is applying for sales license in Europe and America. Nicholas is applying for related patents in many parts of the world.
At the same time, Nicholas began to develop the second generation products. In the process of research and development, it is found that various colors can be used for temperature indication. Considering that the fast food market is very sensitive to the change of cost, Nicholas chose brown and bright red in the first generation of products, so that the cost difference between the old and new coffee cup lids was controlled within a dime.
However, some customers may have more special requirements. As long as they spend a little more money, they may produce products with more functions, thus bringing different experiences to users. For example, change the cover of different companies to different colors, or display personalized information on the cover.
