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

What factors can cause the digital UV printer to crash?

In the event of a crash in the digital uv printer, the consequences are more serious, and generally a large number of pictures are invalidated, resulting in no small loss. The crash occurs when the printing is suddenly stopped automatically during the printing process. The cause of this phenomenon is more complicated. The following is a detailed analysis of the causes and countermeasures of the crash. One type is completely dead, that is, the motion system is completely stopped. The other type is a non-complete crash, which is characterized by a break in print data, but the motion system is still working. The latter brings greater harm and loss than the former.

1. Mechanical failure

Case 1: The motion track of the printhead car is blocked or underpowered. This situation hardly appears on new devices, and devices that take longer to use may appear. The method of inspection is to remove the motor belt, separate the printhead trolley from the motor, and then push the trolley down by hand. If the movement is not smooth, the track or slider should be replaced, because the resistance to the car is large at this time, which will cause the electromechanical malfunction and crash.

Case 2: The print head motor is faulty. Such faults lead to more crashes, and the printhead motors of UV printers are mainly divided into two types, AC and DC. Among them, the AC type has relatively few failures, which is often caused by a long time of use due to wear and tear. The DC type has many failures, and it not only causes a crash due to wear and tear, but also causes unexpected failures, which is a headache.

2. Interference

digital UV printerSources of interference to digital uv printers include external and internal interference. Here mainly analyze the interference inside the machine:

a. Data transmission interference: Data cables that do not have shielding or poor shielding function are susceptible to interference and cause unstable operation. Therefore, it is necessary to use a data cable with excellent performance and high quality. In particular, it is proposed that the optical fiber has excellent anti-drying properties, but it is not suitable for a frequently bent sports environment.

b. Spark interference: If a component that is prone to sparking is used in a UV printer, it will cause many unpredictable faults.

3. Software system

digital uv printerThe software system is the commanding brain of the inkjet UV printer. It is conceivable that the brain has a problem and can it work normally? Software problems occur on the inkjet printer.

In the event of a crash, the entire system is in a state of confusion and the digital UV printer device and software must be restarted. If this kind of fault is rare, it is normal (people will make mistakes, let alone the machine?), but there are always problems.

Know More Applications of Digital Uv Printing

I want to say, the world is filled with UV printing applications if you carefully observe, from small stickers to even complex commercial signages. UV printing applications are everywhere.

That is the special UV inks applied release zero VOC’s, making it a greener process for our environment and be safer. In addition, finished products are scratch-resistant.

Glass, wood, metal printing

The UV printers can use three kinds of inks, including color inks, white ink, and varnish. When you print on transparent or dark materials, you can use white ink as a substrate, and when the printing is complete, you also can print varnish to add gloss pleasant.
Additionally, with the UV inks strongly adhere to the substrate, and
immediately dry up, the high resolution and saturation will lead to
brilliant printing quality.

Signage & Displays
At last, we have to mention signage & displays in UV printing applications. No matter window decoration, vinyl, outdoor signage, indoor displays, UV printing provides flexibility and versatility for the advertising industry. With large size UV printers, we can use CMYK, white, varnish to make rich colorful signs to leave customers deep impression. We can print on vinyl, PVC, acrylic, banner and other sorts of materials.
In short, with UV printers, we can produce unlimited possibility for our life! Keep moving!


The reasons and solutions for uv printer flying ink and cross color

The main reason for uv printer flying ink and cross color:

For static electricity, if the uv printer is in a low humidity environment and the environment is dry, static electricity is easily generated between the print head and the material, so that ink flying may occur during the printing process.

If the voltage of the print head is too high, if the voltage displayed on the head of the print head is bright red and alarm, the flying ink will appear during the use.

When the uv printer is used for a long time, there will be a situation where the machine print head is broken, which will inevitably lead to the machine flying ink.

The electronic control system controls the pulse interval of the printing head to be unreasonable.

The electronic control system controls the pulse distance between the ignition of the printing head to cause the flying phenomenon.

The print head is too high. Generally, the height of the print head and material should be between 1mm and 20mm. If the print head exceeds the range of its own spray, it will definitely fly.

✔For flying ink caused by static electricity.You need to add an electrostatic bar or add a ground wire to shield it.

✔The print head voltage is too high.You need to modify the circuit board, or change the circuit to avoid this problem.

✔ Print the test strip and check the condition of the print head. If it is found to be blocked or faint.And you need to clean the channel of the print head to keep it open. The solution to the disconnection of the print head needs to check the condition of the print head frequently to see if there is any illusion or blockage. If it needs to be processed immediately, the flying phenomenon cannot be avoided.

✔Electronic control system problem, this requires special technicians to carry out maintenance to solve.

✔The distance between the print head and the carrier is too high, so it is easy to solve them by shortening their distance.

Uv printers have some shortcomings, but it does not affect his popularity, because its biggest advantage over traditional printers is that the printing material is not subject to any restrictions, enabling direct printing, one-time imaging, and its printing effect far exceeds the traditional printing effect, can also achieve the embossed personality customization effect, eliminating the need for past repetitive processes such as plate making, filming, color registration, etc. Nowadays, the products are more and more complicated, but no matter how complicated, uv flatbed printer can realize once. Printing, what companies are pursuing is creating value for users far beyond the price of the machine itself!

These operating actions scrap your digital UV printer in minutes

The proportion of digital UV printer on the market is gradually increasing, and UV printers have many problems under such demand. What is especially obvious is the damage caused by the operation of the digital UV printer.

Which ones should be paid attention to when operating the digital UV printer? Let me take a look!

I. Switching machine

digital uv printer(1) Turn on the lights when turning on the lights. Each lamp should be separated by about 1 minute. Do not open at the same time.
(2) After turning off the light, the fan should be kept running for a period of time, until the lamp is cooled.
(3) If you want to start the lamp after turning off the lamp, you must wait until the lamp tube is completely cooled before starting. Otherwise, it will not start when the temperature of the lamp surface is very high.
(4) After the lamp is turned on, it cannot be put into production immediately. There must be a period of lamp warm-up time. When the summer temperature is high, the warm-up time is short. When the winter temperature is low, the warm-up time is longer, and the warm-up time is about 2-3 minutes. If the UV printer has strong and weak light, it should be turned on in the strong light position, which can shorten the lamp warm-up time. If weak light is needed during production, it can be adjusted to weak light after the warm-up is finished.

2. Lamp maintenance

digital uv printer(1) The maximum service life of UV lamps is generally 800-1000 hours, and should be replaced after reaching the end of life.
(2) During the use of the UV lamp, clean the surface of the lamp tube and the reflector on the surface of the reflector with anhydrous ethanol and gauze at an appropriate time (1 to 2 months), and then rotate the UV lamp tube by 180 degrees. The lampshade reflector will be replaced after it has lost its mirror effect.

3. UV lamp and speed adjustment relationship

digital uv printer(1) The best speed selection method: the product is first passed through the UV curing device at a certain speed. If it is cured, the speed is increased until the product passing through the curing device can not be completely cured. The speed multiplied by 0.8 is the most Good speed.
(2) Also pay attention to the use time of the UV lamp. As the UV lamp is used for a long time, the energy will be attenuated and the speed will be slowed down.

4. Transformers, capacitors

digital uv printer(1) The incoming line of the transformer should be selected according to the voltage at the site.
(2) Select the transformer incoming line according to the field voltage, so as to avoid capacitor discharge and injury.

5. Ultraviolet ultraviolet rays can damage the eyes and skin. When turning on the light, please do not look directly at the surface of the lamp with the eyes, and do not let the ultraviolet rays illuminate the skin.

Summary about operating digital UV printer:

This information is suitable for most types of digital UV printers, of course, not all-around, and sometimes a maintenance according to the actual situation of your machine!
