UV print heads

As we all know, the print head is the most important part of the printer, no matter how good your product quality is, and no matter what kind of guarantee your after-sales has, if you usually do not properly maintain the print head or Ignore the maintenance of the print head, once it blocks or damage, you will not be able to operate normally even the best equipment.
Many customers don’t pay much attention to the warranty of the print heads. If a few print heads break down a year, it is a big loss. In addition, the print heads of UV machines are usually industrial-grade print heads, which are more expensive than ordinary printers. More expensive. So how to maintain the UV flatbed printer nozzle to extend the life of the universal flatbed printer nozzle. Through the summary, several methods are drawn for your reference.

1. Cleaning:

For nozzle maintenance, cleaning is the best method. When the day’s work is over, the machine stops running, and the ink is still in the nozzle of the UV flatbed inkjet printer. This requires us to clean the nozzle well. If not, the ink will block the nozzle after a night. The biggest fear of printers is the clogging of the nozzles. Once the nozzles clog, ink needs to draw, which not only wastes a lot of our time, but also wastes ink. Cleaning can be divided into manual cleaning or automatic cleaning. It is best to keep the cleaned nozzles from light.

2. Moisturizing:

Moisturizing is also an important method for maintaining the nozzles of UV flatbed inkjet printers. After the machine stops, there is still ink in the nozzles. If no moisturizing treatment is performed, the ink will solidify and block the nozzles. Moisturizing the print head can effectively prevent the ink in the print head from curing. Even if overnight, the print head will continue to work smoothly the next day.

3. Disassembly, cleaning, collection and maintenance:

Although cleaning and moisturizing can protect the print head from blocked, if the printer has worked for a long time, the best way is to remove the print head for cleaning, and then seal the print head for storage. Sealed storage can prevent particulate objects in the air from contacting the nozzle and block the nozzle.

The above is a few maintenance methods for UV flatbed inkjet printer nozzles summarized by the editor. Through our usual careful maintenance, to achieve the above three points, I believe that the service life of the nozzles will be prolonged.

Digital UV Printing VS Traditional Screen Printing

When it comes to printing, the field of vision has seamlessly expanded beyond clothes and T-shirts. Now people can imagine almost everything being printed and customized, such as glass doors, desktops, exquisite mobile phone cases, and even metal. The invasion of technology has brought new things and may also bring opportunities for enterprises. This has sounded the alarm for the latest printing innovation, which is digital UV printing.

Which is better? 

A face-off between modern and traditional printing technologies will give a better idea as to which technology can reap better results. Here are a few parameters worth considering:
1. Cost
Cost is of paramount relevance. UV printing is a linear process irrespective of the quantity and is beneficial for a lower quantity of production as no setup costs. Screen printing needs to create a wide range of stencils, so they are not suitable for lower quantities. However, if bulk order, and print same stencils, hence screen printing may be viable.

2. Products to be Printed
Screen printing is a robust technology but majorly concentrated on apparel and t-shirts. Digital UV printing can print on almost any kind of surface like acrylic, aluminum, glass, metal, and wood. A plethora of items like pens, doors, mugs, mobile covers, trophies and many more. UV printing has revolutionized the market with customization and personalization. The gifting industry has seen a boom with UV printing technology.

3. Use of Inks
UV printing uses ink that contains a chemical called photoinitiators which trigger a chain of reaction under UV light. This ink dries up instantly with UV-light.

The screen printing uses three types of ink-plastisol, water-based inks and discharges inks. Each ink has limitations with regard to the drying up the process and the after-wash quality.

4. Environment-Conscious
With an increasingly aware generation, this factor is gaining importance gradually. Plastisol used in screen printing contains PVC, which is a harmful pollutant. Water-based inks are relatively more eco-friendly. However, UV printing is very environment-friendly which neither uses heat nor toxins in the process; hence is a hands-down winner of this category.

Why say UV ink Environmental-friendly?

UV printing has a wide range of applications. digital UV printers can directly print on coated and uncoated flat and roll media and three-dimensional objects, such as pens, iPhone covers, coasters, tiles, canvas, glass, ceramics, metals, ceilings, acrylic, wood, PVC, PP, PE, reflective film, leather, carpet, etc.

Advantages of UV ink:

After printing, the printing medium can be used for post-processing without adding paint, saving costs.
UV ink emits little VOC and garbage smell. Environmental protection is another advantage of UV ink.

Durability: The UV printed logo placed outdoors can hold for 3-5 years without fading, yellowing, cracking, and can be kept for about 10 years in an indoor environment.
Print quality: The print quality is better and can be printed on various media.
The ink dries and solidifies quickly. Once the UV-guided light touches the surface of the substrate, the UV ink immediately dries and cures.
Energy-saving UV LED lights can be turned on and off immediately without any energy for preheating and cooling. Workers have no time to wait to start work. Save power consumption and improve production efficiency.
Good light fastness and smear resistance.
When using UV varnish, it has a pleasing final print output gloss, thereby increasing outdoor durability, tear-resistance and abrasion resistance.
Use unique UV white ink to achieve a spot embossing effect. Able to print on dark, transparent and colored surfaces.

UV printing VS Solvent printing

Many people have heard of solvent printing and UV printing, but few people fully understand what they are or the difference between them. These two printing methods are especially widely used in the advertising banner industry.
UV printing is a commercial printing process that involves the use of UV curing technology and strong UV explosions for printing. On the other hand, solvent-based technology mixes solvents and pigments together to form a liquid ink that leaves a hard layer of ink after evaporation. Unlike UV printing, which is actually harmless to operators, solvent printing is spread in the air, so it is extremely toxic and dangerous.

This is one of the main reasons why UV printing technology has quickly become a new industry standard. Nowadays, more and more companies are converting their solvent printers into UV printing solutions. After all, in any work environment, safety should always be the top priority.
Since the UV printer uses a UV lamp to fix the printed image, it does not use solvents. This means that this printing method does not require ventilation.

UV printer advantages

UV printer advantages

The following are some advantages of UV printing:

Optimize drying time; the ink dries in the second after it comes off the press, allowing you to fold, staple or perform any other finishing operations almost immediately.
All UV printers can print on many different materials, including paper and non-paper substrates.
UV curable ink is not easy to scratch, fade, scratch or stain during handling and transportation.
The UV printing process is more environmentally friendly. Since the UV-curable ink is not solvent-based, it will not evaporate any harmful substances.
Enjoy clearer, brighter, and more vivid effects.
However, one of the main advantages of UV printing is the quality of the printed results. The prints of UV printer is much better,  because UV ink has no chance to absorb or spread due to the short drying time.

With the continuous advancement of technology, the industry has predicted that UV printing will continue to develop and improve. Unlike solvent printing, UV printing has reached its technological peak. With this in mind, if you are considering upgrading your current printers, it is much wiser to invest in UV printers instead of solvent printers.

Therefore, compared with solvent printing, UV printing has proven to be successful. Provides a wider color range, better details, safer printing, clearer images and faster printing speed. It is not surprising that more companies choose UV printers instead of solvent printing than before.
