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.

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 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.

How to choose right UV ink for printer?

There are four principles for UV printer users to choose UV ink: print head model, material characteristics, ink performance, and after-sales service.

1. Print head model principle

Different nozzles determine that the UV ink used is different. Even the same brand of nozzles, but the internal series, the UV ink used is also different. Common ones are Epson nozzle UV ink; Seiko nozzle UV ink; Polaris nozzle UV ink; Toshiba nozzle UV ink; Kyocera nozzle UV ink; Konica nozzle UV ink; Ricoh nozzle UV ink; Xaar nozzle UV ink.

2. Material characteristics principle

The types of materials of the user’s own products are different, and the UV inks used with them are also different. For example, flexible material UV inks include: wallpaper UV ink; soft film UV ink; leather UV ink; car sticker UV ink; lightbox UV ink. The UV inks of rigid materials are: ceramic UV ink; glass UV ink; acrylic UV ink; mobile phone case UV ink; metal UV ink.

3. Ink performance principle

Some products pay more attention to outdoor weather resistance, environmental protection, high-temperature resistance, and other treatment processes that are not peeling or dissolving. This is more troublesome and requires special customized UV ink.

4. After-sales service

Usually, UV printer users use the UV ink provided by the manufacturer and enjoy the corresponding warranty service. However, due to personal replacement of UV ink, cleaning fluid, etc., the print head blockage, ink system damage, etc., are not covered by the warranty.

Is it good to buy a new uv printer or a second-hand one?

What should I pay attention to when purchasing a UV printer? Is it good to buy a new uv printer or a second-hand one?

The resale of uv printers is a common phenomenon. Some of them are because the equipment is not good. If you want to sell them cheaply, you can earn some money by earning some money. Some are because of the change, do not do this business, the equipment is idle. There is also a better equipment, the original flat-panel printer still occupies the place after it is empty, it is better to resell and so on. So what do you need to pay attention to when purchasing a UV printer? Is it good to buy a new uv printer or a second-hand one?

Note 1:

Resale of used uv printers, the original manufacturers do not provide free after-sales service.Therefore, if the user who purchases the second-hand printer, the after-sales service is required to pay a certain fee, the manufacturer will come to the door.

Note 2:

uv printerUnderstand the real situation of the equipment, the key is to understand the state of the printhead, the state of the motherboard, the wear status of the parts such as the click, the platform, and the guide rail. If physical wear is very important, then it is cheaper to consider, and it is impossible to buy it. .

Note 3:

View the contract, invoice and other information signed by the user of the purchased uv flatbed printer. Understand the basic situation of the manufacturer, origin, performance and other equipment. Avoid buying some machines that are used by middlemen to disassemble and arbitrarily piece together.

Note 4:

uv printerWhen investigating the situation of second-hand machines in the field, if there is a condition, the master with a uv printer will now view and operate it. It will be more real and comprehensive, and will find some problems that are easy to ignore, and it is easier to see a more realistic situation of the equipment. .

Note 5:

It is important that the operating software is encrypted. Some uv printers will be encrypted on the motherboard program, 3-6 months / decryption, users need to pay the encryption fee to continue to use. This is very disgusting, don’t buy it when you encounter this kind of machine.
