Why Colmar Printing Better than Traditional Printing

Glass is one of the most commonly used materials in home decoration. The applications include decorative mirrors, glass doors, glass walls and so on. But how does an ordinary glass be processed into furniture with beautiful patterns?

Let's talk about several glass processing techniques.


1.Spray paint

This is the most simple and traditional process. In the glass furniture of the early years, we can often see the use of this process. Workers need to put a layer of paper film on the glass in advance, and remove the paper film that needs to be painted. The injection machine generates high pressure to spray the paint in the mist, forming a paint surface on the glass surface. After drying, remove the left white film and the pattern we want is formed.
This kind of technology is relatively old and has no advantages but only disadvantages. It produces only single color instead of multicolor images . Secondly, the paint is highly polluting the air, and the place where it stays has a great impact on the health of the surrounding residents.


2. Silk screen

Silk screen printing is also called screen printing. Screen printing is a contact printing method. First, make the image pattern into a silk screen plate, and then color the glass surface according to the pattern.
Silk screen printing is much better than paint method, and can print a variety of colors. While the shortcomings are obvious too as silk screen can't do complex colors, and each color should be re-plated. If you want to make a gradient color, silk screen can't do anything. If an image has 100 colors, it will take 100 times of labor, which is very inefficient for complex colors print.
In addition, from the perspective of environmental issues, silk screen does not pollute the air, but as it needs to be washed every time, it will impact big pollution to the water resources.


3.uv printing

The UV flatbed printer uses digital printing technology, and the computer's control of the ink can be accurate to the pl (picoliter) level. The color will be printed at the place where printing is required, and does not eject ink at all where printing is not required. Only this one is much better than the other two printing techniques mentioned above.
Due to the use of digital printing technology, no matter how complex an image is, it is printed at one time.
Also, In terms of the cost, UV printing has much advantages too. For example, simple 4-color printing, the ink cost of UV printing per square meter is close to that of silk screen printing, but the labor cost is only one-fifth of the silk screen printing. And with more complicated patterns, artificial silk screen can not do at all.
More, UV printing can be used to make 3d effects by white ink overprinting, which is different from painting and silk screen printing. UV printing does not pollute the air nor the water resources, it not only protects the environment but also saves the cost of the enterprise.
