How does the paint color on the surface of the water cup and the color of the text on the surface of the water cup are different at different light angles?

Recently, a friend left a message, asking how the color of the surface of some water cups will change with the angle of the light, how is this formed?What process is used?In addition, recently, the logo printing on the surface of the water cup has also begun to appear with different light angles, and the logo will also change in color. The editor will share with you today.

With the continuous improvement of the surface treatment technology of drinking glasses, more and more processes that have been used on other items are used on drinking glasses.In 2017, some manufacturers received the design requirements of the customizer and began to perform mirror effect treatment on the surface of the water cup.At that time, the electroplating process and mirror polishing process were mostly used, but because the electroplating process contained heavy metals, it did not meet the food-grade requirements of water cups.Although mirror polishing meets food-grade requirements, due to the difficulty of the process and the high processing cost, some companies and technology companies specializing in technology have developed a vacuum plating process.

The colors processed by the early vacuum plating were mainly solid colors. With the maturity of technology, many manufacturers can process and produce vacuum plating effects with gradient effects. After the appearance of the gradient color, with the change of the light angle, there has been a faint change in the color of the surface of the water cup, but it is not very obvious. After the water cup with this effect was put on the market, it was used by some brands for effect design. Therefore, through the adjustment of the vacuum plating material and the adjustment of the spraying process, the effect of changing the color of the light angle is obvious. Many water cups whose appearance design is not very good are blessed by craftsmanship, so that the water cup presents a dreamlike effect, which adds a lot to the final product.

The logo or text on the surface of the cup will also change with the angle of the light.In fact, it is very simple. This process and technology belongs to a layer of window paper that can be broken with a stab.The basic processing methods for this process are still thermal transfer printing and water stickers.The editor once asked a friend who does heat transfer if he knew how to do it.The other party was hesitant, which shows that the other party's knowledge of the processing method of the sticker material is relatively limited.

The text or logo can change color with light because the pattern uses a laser process.This process has been adopted by the majority of printing institutions in the 1990s.At that time, the printed matter with laser effect was mainly used for anti-counterfeiting.The complex color pattern on the water cup needs to be printed by the printing machine first, and then transferred to the surface of the water cup by a method similar to the thermal transfer water sticker process.

Therefore, the color-changing logo or text on the surface of the water cup is first produced by a laser printing process to produce a color-changing pattern film, and then transferred to the water cup by thermal transfer or water sticking process.However, the baking temperature must be strictly controlled during production. High or low temperature will affect the effect of discoloration.
