What’s The Differences Between Uv Ink and Solvent Ink?

As you know uv ink is a consumable that is specifically designed for printing patterns on uv printer equipment. It has a pigment particle diameter of less than 1 micron, is free of volatile organic solvents, has ultra-low viscosity, and has no irritating odor. It ensures that the uv ink does not clog the nozzle during the jet printing process. UV ink is spray-dry, suitable for printing metal, glass, ceramics and other materials. The cured ink layer has high hardness, strong adhesion, scrub resistance, solvent resistance, high gloss, and strong outdoor weather resistance.

uv ink The difference between UV ink and solvent ink
UV inks and weak solvent inks determine their respective application methods and applications due to their inherent properties. Since the UV ink is attached to the substrate, it can be embossed after repeated printing. The weak solvent does not adhere to the surface of the carrier but penetrates into the carrier, so there is no way to print the relief effect. Since many materials in the weak solvent need to be coated when printing, unprinted printing products are easy to fade, while UV ink can be directly used to print many materials without any coating treatment. Simple, convenient and practical.

solvent ink

The UV ink reduces the volatile organic matter that escapes from the solvent-based ink during the heating and drying process, and should be matched with the post-processing equipment for post-treatment. The post-treatment method mainly uses the catalytic oxidation method and the cooling recovery method. UV 100% liquid content, no VOC, so there is no environmental pollution problem. Because of its non-toxic, instant drying, fine ink particles, high concentration, good stability, etc., it has been widely used.

sulimation ink

Uv ink can eliminate the hot drying tunnel and oven accumulating volatile organic matter post-processing equipment. Since the ink is not dried by the heating and drying method, the mechanism and the electronic component are not disturbed by the high temperature caused by the heating, and the shrinkage, thermal expansion or warpage of the roll is not caused by the high temperature. Therefore, the current amount of UV ink is increasing at a rate of 10%-20%/year.

Which One is Better Between Traditional Inkjet Printers & Uv Printers?

For many people who have just been exposed to uv printers, many people want to know which uv printer and traditional inkjet writing is better? From the rapid development of traditional photo printing, we can understand that the current application of printing is very extensive, and the market needs are also very large.

inkjet printers However, UV printing is more skillful and preemptive in the traditional solvent and weak solvent printing. Under the application of UV printing, it can finish higher-end printing applications and is compatible with more printing media, which makes it involve a wider range of occupations. category. Under the application of UV printer technology, the cutting-edge UV printing equipment is also continuously pushed. For example, the UV coil flatbed machine is compatible with many different types of flat-panel type UV flatbed printers, and the user can more easily complete the UV print output. UV printing is the most anticipated type of printing for printing now. It has been widely implemented and applied in the field of wild advertising manufacturing.

So what’s the advantages? What is the difference between a uv printer and a traditional inkjet machine?
UV printing is compatible with more printing media, and it is widely used in a wide range of applications. UV printing is widely used because of its scale and scale. Ordinary weak solvent photo printers are not constrained by raw materials because they are constrained by raw materials. UV printing is suitable for any raw material, and has the characteristics of high speed, high precision and stable performance. Therefore, it is manufactured in inkjet printing. The occupation has been implemented and applied on a large scale.
UV printers have a very good effect on inkjet printing in traditional weak solvent households.

UV printing can be printed quickly and finished. The traditional inkjet printing operation is performed by using inkjet ink or solvent-based ink. These inks need to wait for the ink on the surface of the paper after printing and printing. It is dry and simple, and it is affected by different temperature and humidity. Especially in humid climate, traditional inkjet photo printing needs long-term waiting for the screen to dry, and even need to cooperate with drying equipment for drying ink treatment. After UV printing, the UV ink can be quickly cured by the simultaneous UV UV lamp, which is fast and tidy, and the printing speed is fast, that is, it can be taken right away, without long-term waiting, which can make the print and print transaction more complete and save time. And artificial capital.

What’s The Principle of Uv Printer and How Dose Uv Ink Works on Uv Pritners?

What’s the principle of uv printer and how dose uv ink works on uv pritners? The ink we are talking about is UV ink. I can’t see the light because he is UV-cured. So his ink cartridges are also black. The principle of the UV flatbed printer is actually the principle of inkjet.

uv printerThe UV ink is directly sprayed onto the panel through the nozzle. Cured by LED lights. Just hit it. More convenient. The unevenness is the relief effect. Because the UV ink is a hard ink, the intensity of the relief effect can also be adjusted. Weak solvent inks can’t be bumpy.

UV printing is a form of digital printing that uses ultra-violet lights to dry or cure ink as it is printed. As the printer distributes ink on the surface of a material (called a “substrate”), specially designed UV lights follow close behind, curing – or drying – the ink instantly.

 

The principle of UV printer is not difficult, but in practical application, from ink and print head to processing, there are high technical requirements. Here are a few aspects:

  1. UV of uv printer means Ultraviolet (uv).
  2. UV printer uses special uv ink, which is sensitive to ultraviolet light and quickly solidified after absorption.
  3. The head printer of the uv printer is piezoelectric principle and what is piezoelectric? It is the process by which the semiconductor transforms the external pressure. The most common one is the lighter. The one that hit the fire is the voltage of the electric appliance, which can produce a spark that can produce hundreds of volts.
  4. The uv printer can be used for almost any material, ceramics, glass, plastic, stainless steel, leather, cloth.
  5. To judge whether a uv printer is good or not is the processing technology, such as making wood very well, but stainless steel and glass are not easy. How to make sure that printing is not discoloring, not peeling, wear-resistant and scratch-resistant, which requires some coating material to be printed to do secondary treatment of the printed material. Different processes have different effects.UV printer

How do UV printers choose the right UV coating?

In recent years, UV printers have won unanimous praise from the industry for their environmental protection and high efficiency, and their coverage has grown rapidly. The attractive feature of UV printers is the diversification of its printing materials. The application of inkjet printing technology has expanded from ceramics, glass, metal, acrylic, wood and other materials. However, the adhesion of uv ink on the surface of some smooth materials such as glass and ceramic is not good, and it is easy to fall off. Therefore, it is very important to use a coating to help uv ink adhesion.

UV printer coatings do not appear for a long time, and the quality of the coatings sold on the market is uneven. Low-quality coatings will not only affect the printing effect, but also damage the machine. How to choose the right UV coatings, what aspects should be paid attention to?

UV printers

Leveling:
Leveling is a common performance indicator in paints. It refers to the ability of a paint to be applied to a surface of an object, such as brush marks and spray mist, which are automatically spread into a flat, smooth surface. A uv coating with poor leveling affects the decorative effect of the printed matter. More importantly, if the brush marks on the surface of the coating do not disappear automatically, the uneven surface of the coating may rub against the UV printer nozzle, causing significant damage. High quality coatings should be formulated to quickly level off after painting or spraying.

Weather resistance:
For UV printing products, especially for outdoor signs, billboards, printed materials must be bright and new for a long time without fading. Specifically, this requires that the uv coating has a function of resisting ultraviolet rays. Some coatings now turn yellow under long-term lighting conditions and are not suitable for outdoor use. Even for UV-printed products that are used indoors only, it is generally necessary to consider the use of weather-resistant uv coatings to ensure product quality.

Film transparency:
As a high value-added decorative product, UV prints generally have high requirements for appearance. This requires that the uv coating film is colorless and transparent. There are some epoxy-based two-component coatings on the market that form yellowing and affect the decorative effect.

Product safety:
This is a question that must be considered. The solvent-based uv coating not only has a large odor, but also poses a safety hazard in the case of improper storage, and is inconvenient to transport. Because of the high investment in UV printers, a safer aqueous uv coating should be considered when choosing a uv coating. If a solvent-based coating is necessary, it is recommended to store it separately from the UV printer to prevent potential safety hazards.

Easy to use:
The uv coatings currently on the market have two-component and multi-component products, and the one-component uv coating that is not required to be configured has a greater advantage in use than the multi-component product.

Adhesion:
It is very important that there are many ways to measure adhesion, such as the Baige method. If the quality of the printed product is high, it is also possible to test whether the printed product is immersed in water or the boiled spray surface is peeled off. Adhesion is the key to measuring the quality of a uv coating. High-quality coatings should pass the 100-gram test and do not fall off after soaking in water or boiling water.

UV printers

Therefore, when purchasing uv coating, it is recommended to choose the UV printer manufacturer to sell or the manufacturer recommended, after all, the quality of the manufacturer is guaranteed.
