Glass decoration:

Glass has many kinds: white glass, tempered glass, frosted glass, etc. Normally printable glass has coating layer, which can solve the problem of adhesion. After the coating layer dry, you can use the UV printer Just print, then dry, with bright colors and high-end atmosphere. Glass applications: background walls, entrances, sliding doors, coffee table panels, 3D crystal jewelry, etc. The tempered glass needs to be printed after tempering, otherwise, the pattern will fall off when tempered in the tempering furnace (the tempering furnace is around 700 degrees). Nowadays, The popular color + white + color printing solution, manufacturers can print double sides of glass, and the pattern effect on both sides.
Glass products are suitable for people: home improvement, tooling, school, hotel, KTV, restaurant, tea house, facade room, etc.

How to choose print heads for UV printer?

Nowadays, UV printer heads in the printing market, like Epson, Kyocera, Konica, Ricoh are generally the most common brands. Nozzle life, Accuracy, Stability these factors directly affect the use of subsequent equipment. The core is to look at the price of the nozzle, cheap nozzle is not as good as an expensive one. In fact, there are lots of customers who are not particularly understanding of the nozzles, so here will popularize some of the UV printer nozzle tips for everyone.

1. Epson printhead

As we all know, Epson nozzles have been independent in the era of Japanese inkjet printer. Epson print heads we mainly see in Japanese series machines such as Mimaki, Roland, Mutoh, etc. At present, domestic inkjet printer has also begun to use Epson DX5 to take the lead. Besides, with the development of domestic inkjet printers, indoor and outdoor piezoelectric wide format printers are all high-performance and high-precision Epson DX5 piezoelectric nozzles.

2. Konica print head

Konica nozzles are double-row ink tubes with uniform flow and pressure. Ensure print quality. Some brands are single row. The 512 Konica printhead is a fully enclosed printhead, waterproof and anti-aging. Konica nozzles have poor ink compatibility and strict requirements for inks in different seasons. They are sensitive to environmental temperature changes. The nozzle plate exposes, and the ink will burn the nozzles. It is easy to break the ink at high and low temperatures. Use Life expectancy is less than 1.5 years.

3. RICOH print head:

Ricoh nozzles are mainly suitable for high-end industrial UV printers. Like most of the one or two million machines imported abroad, using  Ricoh print heads. With the same industrial printhead machine, Ricoh’s printing effect is definitely the best, the clearest, and can basically achieve the printing effect of Epson. Double-row ink tube with fine ink dots and grayscale printing fully enclosed nozzle, waterproof, anti-aging Ricoh Gen5 nozzle has a built-in constant temperature system, the printing voltage is adjusted with the temperature, then achieving a more stable printing state. The circuit board of the nozzle is all metal, so it can be soaked in ink without causing damage to the nozzle. The life of the nozzle is long, and it can be used normally for 3-5 years, so we think this is the most successful piezoelectric nozzle. The single-color control of a single nozzle, the all-steel structure super corrosion-resistant nozzle has both speed and effect, but its disadvantage is that the price is more expensive than other types of nozzle machines.

Tip of UV printer maintenance in Winter

When it gets cold in winter every year, the number of failures of UV printers will also increase, mainly in four areas: print head nozzle blockage and disconnection, consumables solidification and condensation, electrostatic interference, and voltage instability. In view of these situations, how to prevent them in advance.

1. The print head blockage and disconnection.

After the temperature drops in winter, the print head will block and disconnect. Don’t worry too much. This is mostly because the viscosity of the UV ink increases and the fluency of the ink decreases after the temperature drops. Individual print heads do not emit ink smoothly.

Solution: In addition to the automatic stirring and heating of conventional large ink cartridges and secondary ink cartridges, heating plates can be installed on both sides of the ink outlet of the nozzle. If it is not convenient to install, you can choose a small sun and keep 30cm Distance, illuminate the head car, if possible, you can turn on the heating or air conditioning to keep the working environment temperature of the UV printer above 25 degrees.

2. Consumables are solidified and condensed.

Users of UV printers found that the ink in the UV ink bottle has become viscous, and some of it has condensed. When this happens, it means that the ink has been scrapped and cannot work, mostly because the ink bottle is placed directly on the ground.

Solution: The storage of consumables in winter must be placed on the shelf, not on the ground, and not in the open air.

3. Static electricity interferes

The direct effect is that the ejected ink droplets deviate from the direction due to static electricity, causing the phenomenon of “flying ink” or “ink splashing”, and the print quality will be seriously reduced. In severe cases, it will cause the circuit to burn down.

Solution: In addition to installing the necessary ground wire, the cleaning of the working environment of the UV printer requires 2 days/time for maintenance to reduce dust. If the air is dry, just turn on the humidifier. If possible, an electrostatic rod can be installed on the machine to eliminate the electrostatic interference of the material itself.

4. The voltage is unstable.

In winter, due to the heating demand, a large number of electrical appliances will be turned on, and the current and voltage will be overloaded. These instabilities will affect the normal operation of the UV printer in the light of it, and will directly burn the internal circuit.

Solution: In addition to choosing a UV inkjet printer from a regular manufacturer (the circuit system has preventive and emergency solutions), a voltage stabilizer must be installed, a backup power supply and a separate line for the equipment must be installed. It cannot be mixed with other electrical appliances.

UV printer VS Latex printer

UV Printing VS Latex printing

UV Printing VS Latex printing

The large-format print industry is evolving rapidly and experiencing growth & change with the influx of technologies in the market.
UV Printers offer many benefits in LFP market. UV Curable printing always offers opportunities to reduce the impact of printing on the environment relative to solvent-based printing. It is still considered to be fast-growing technology in the wide-format market.

UV printers are excellent for any application which involves the printing of a variety of substrates. The inks are cured and fixed with UV light. Both flexible roll materials and single sheets, but also rigid print media and even glass can deal with it. Latex printers require preprint and post print heaters to cure the media, resulting in higher energy consumption compared to other inkjet technologies. Some substrates may buckle under the higher temperatures.

Main Advantages of UV Printers over Latex:

1. UV Curing provides more Print options in various substrates
2. Lower Picolitre drop sizes compared to Latex
3. Less Maintenance
4. Less consumables
5. Less Operating Cost
6. Reduced Material Cost
7. Less Downtime in production vs a Full day in Latex
8. 1-2 or even fewer print heads to be replaced compared to 20 to 30 printheads in Latex over its life.
9. Ink Yield is 25 to 30 % more
10. Ink consumption is cheaper than latex.
11. Less Power consumption.
12. Lower cost per sqm.

According to a survey, print service providers have started shifting their buying preference more towards UV printers than latex printer. (50% favoured UV while 32% indicated to purchase Latex).

Latex printing

Latex printing applications

Latex inks have a limited choice of materials because the ink must be fixed under heat. However, UV ink dries instantly, which makes it excellent for non-absorbent substrates such as PVC, carton, wood, aluminium, glass, and ceramics, etc. UV inks are also suitable for printing on rigid and uncoated print media. UV Prints are extremely durable (UV-resistant, water-resistant, scratch-resistant), gives true colour output and exceptionally high quality. It is generally possible to print much faster-using UV ink than with aqueous or solvent inks.

Is Epson print head really inferior to industrial heads?

When it comes to print heads, the first thing everyone thinks of is the printer.
Now the well-known printers like HP, Epson, Canon, Lenovo, Brother, Samsung, and so on. These printers are the current office printers in China.
So what we are talking about today is the relatively popular UV printers in recent years. As long as the printer must use the nozzle. Even laser printers are no exception.
Now domestic UV printers are mainly divided into Epson series, Seiko series, Ricoh series, Konica series, Kyocera series(Depends on print heads).
We mainly see UV printers like Epson heads small UV printer, and Ricoh heads industrial UV printers.

The difference between Epson and Ricoh printheads!

90% small and medium-sized models UV printers use Epson print heads. Because Epson print head is suitable for small batch personalized prints, rather than mass production.
Everyone knows that there is a large-scale 2513 UV printer(UV models depend on print format size), and many manufacturers also install Epson nozzles.

Why is it not suitable for large UV machines to install Epson nozzles?

Large industrial machines such as Ricoh nozzles are equipped with positive and negative pressure systems, and the ink is more uniform.
One of the reasons why Epson is not suitable as a printer: the format is too large, the ink supply is insufficient, and the ink is easily broken during printing.
Epson print heads are now used in small and medium-sized models, and Epson’s nozzles are very large. There are too many DX-series and XP-series alone. The XP600, which is called on the market, actually does not have this type of nozzle.
Besides, Epson print heads are cheap, many manufacturers use second-hand or refurbished. Especially after Epson has encrypted many nozzles, this phenomenon is even more serious.
Many people have problems after buying a small UV printer, mainly because there are many reasons for the print head. Therefore, many users think Epson heads UV printer is bad for business.
