Epson EPS3200 (WF 4720)
Nearly the same as Epson 5113 printhead in appearance, specification, and performance, but gain much popularity in customers due to cheaper price and sufficient supply, and that Epson 5113 has already stopped to produce. Recommend it.

Epson 5113
It is an alternative of DX5 when utilizing water-based ink. However, EPS3200 has increasingly replaced it with rich supply and ink compatibility.

Why Choose Large Format Printers for Digital Printing?

digital UV printers

Large format printing is a kind of advertising medium which has only risen in popularity over time. The main aim of this technology is to support the maximum width rolls in printing. For printers, they enjoy a larger area to express their skill. Large format printer is used to print murals, banners, wallpapers, and posters. These are perfect for materials which have a dominance of graphics or visuals. The large texts and images make the large format prints extremely effective advertising tools. The result is a greater impact. A bigger number of customers are usually attracted to large format printing.

Process advantage

Large format printing is known by other names like grand printing or wide-format printing. Prints are not done on individual sheets. Instead, prints are made in rolls which are fed incrementally. The printing process itself is similar to digital with the exception of being a bigger printer with nozzles. Paper stocks are fed into printer whee ink gets directly applied into the material. The printing phase is much faster-producing premium quality colors. A wide format printer has seven important components: ink supply station left rear cover for ink, heater, right rear cover for ink, waste ink bottle, roll paper, and USB station.

The wide format printers themselves are highly efficient machines which generate high-quality results. These are water-based. The UV inks are much duller in color and resist fading. They are also excellent for outdoor use.

Wide usage

Posters are generated through large format printing. Wall decors, tradeshow displays or POP, retail graphics, and photo prints are displayed. It is possible to mount them in gator boards or semi-gloss paper dominant stock. Vinyl banners are also printed through wide format printing. These are also extremely popular when it comes to outdoor usage. They are excellent for exhibit displays and trade shows.

Large format printing is also used to generate wall stickers or graphics. These are excellent to jazz up any wall. Interior spaces can be provided a completely new perspective. The wall graphics generally get printed on the sticker papers. Su ch prints are resistant to fading and can be repositioned if needed. Consumers nowadays are increasingly turning towards large format printing as they want everything fast and cheap. The wide format printing method perfectly suits such requirements. These are much more affordable compared to other print techniques like screen printing. This kind of printing can be easily made and the production cost is also cheaper. Higher quality printing can be achieved from standard quality materials.

How to make the printhead of UV printer like the new?

UV printer printhead maintenance methods are available in four ways, including initial installation, routine maintenance, fault maintenance, and maintenance during the fake period.

After the equipment is installed, the equipment is initially installed to maintain the print head.

In order to get the printer head into optimal operation, before the UV printer officially begins to undertake the production business, please be sure to print some pictures as much as possible in 1-2 days. The picture is best CMYK/LC/LM/W 7 colors. Used, and add color bars on both sides of the screen to ensure that 7 print heads are always in the inkjet state.


How to maintain the print head after the daily work is completed?

In the off state

After all the print jobs are completed every day, in order to keep the print head in optimal working condition and to avoid clogging the printhead due to UV ink evaporation, please follow the method below to maintain the device and let the device stay overnight.
1. Turn off the UV printer power supply.
2. Clean the non-woven fabric with a special cleaning solution, then pour the cleaning solution onto the non-woven fabric to make it wet.
3. Move the handpiece back to the rightmost cleaning station and tightly bond the nozzle to the nonwoven.
4. Keep this state for the device to stay overnight.

Power on

1. Turn off the UV lamp and draw the wind on the platform.
2. Print the test strip, check whether the print head status is intact. If not in good condition, continue to maintain the print head until the print head is in good condition. (no needle, no oblique spray)
3.Do not turn off the computer and software, let the machine standby flash.


After the printhead was found to be slightly blocked, the treatment method was found.

1. Regularly maintain the print head (slightly wipe the print head surface with a non-woven fabric) until the nozzle is in good condition.
2. Cleaning solution maintenance (squeeze the surface of the print head with a sponge stick to the cleaning solution for 1-2 minutes), then wipe the surface of the print head with a non-woven fabric, check the print head status diagram. And repeat the operation several times until printing the head status is normal.
3.Combined with the cleaning solution maintenance method, increase the print head correction voltage 1-2V print 2 m * 1 m color block (print the print head state problem color color block) interval 2-3 times check the printhead state map until the print head status normal.
4. Do not rinse the print head without authorization. If the print head is damaged, the consequences will be at your own risk!printheadAfter the equipment is installed, the equipment is initially installed to maintain the print head.

The UV printer is not used for a long time, and the printer’s print head is easily blocked. Especially during the Spring Festival, the temperature is relatively low, and the ink is prone to deposits and impurities after being frozen. Ensure that the room temperature is between 20 ° C and 30 ° C. If the temperature is too low, it may cause serious damage.


How do laser&inkjet printers work?

You probably know that two most common types of printers for office and home use inkjet and laser. Though still might come across old matrix printers that are mostly used in banks.Both laser and inkjet printers have their advantages and disadvantages.

Laser Printer

Laser printers include not only laser but also contain rotating cylinder coated with photosensitive electrically charged material and series of mirrors. When you are sending a document to a laser printer, laser light is reflected by the mirrors on to the cylinder which neutralizes electric charges in specific areas.

Thanks to the rotation of both cylinder and the mirrors, as well as the lasers are turning on and off at precisely correct moments the areas hit by the laser correspond to the actual print. So when the toner particles hit the cylinder they only stick to the areas exposed to the laser light, because the toner itself has an electrical charge too.

Then a sheet of paper is pressed against the cylinder and the toner is transferred through the paper using heat which fuses a toner to it. That is why pages right from the laser printer are always warm.

Due to the precision of the laser these kinds of printers are great for producing crisp and clear text.

Inkjet printer

The other printer type – the inkjet printer, which uses a very different technology. This type of the printer uses liquid ink instead of solid toner particles.

In consumer models, inside of the very expensive cartridges. ink is heated with the electrical charge to vaporize an extremely small amount of ink and form a bubble on the nozzle. The bubble then collapses and the pressure difference pulls a droplet of ink out of the cartridge and on the paper.

Because the internal procedures of the inkjet printer are more simple than the ones of laser printers, they intend to be much cheaper. It is fact that inkjet cannot print as quickly as laser printers, however they can give much better print quality of the photos. So this technology will be the right choice for those who are looking to print their images from DSLR or phone at home.

On the other hand, lots of wide-format inkjet printer owners were disappointed by their printer’s reliability. This is partially caused by extra small moving parts can break. The small nozzles that were mentioned before can clog easily.

Another confusing thing about the inkjet printers is the business model of their manufacturers. The printers themselves are frequently sold for the price that is lower than their cost. That is why the ink usually refills cost a lot. Some manufactures program microchips inside of the cartridges to request ink refill even when the cartridge is not empty.

But the things are getting changed slowly. You can find alternative systems that can be integrated to your printer instead of the cartridges.

Requirements for digital printing inks

The key to digital printing is ink. Inkjet inks must meet certain physical and chemical standards and have specific properties to form droplets. They are suitable for specific inkjet printing systems and provide excellent image and color vividness. The performance of the ink not only determines the effect of the printed product, but also determines the shape characteristics of the droplets ejected from the nozzle and the stability of the printing system.

The basic performance requirements for reactive dye inkjet printing inks are as follows:

Surface tension

The effect of surface tension on ink drop formation and print quality is extremely significant.

From the observation of the presence or absence of spillage around the nozzle during the inkjet test, the length of the droplet breakage, the stability, the droplet velocity, and whether it is running in a straight line, the quality of the droplet formation can be evaluated, all of which are subject to surface tension and viscosity. influences.

Too high surface tension makes the print head surface not easy to be wetted, the ink is not easy to form small droplets, and may have a long break length, or break into a “tailing” shaped droplet, and the ink build-up around the nozzle will affect the fineness. The linear operation of the droplets and the reproducibility of the printing effect.

If the surface tension is too low, the droplets will be unstable and even form a “satellite”, creating a sputtering spot. It is generally required that the surface tension of the inkjet ink is lower than that of the printed substrate, and the contact angle of the ink droplet with the substrate is greater than 140 degrees to obtain a clear pattern.

In summary, a suitable surface tension requirement is that the ink can be easily infiltrated into the interior of the fabric without causing percolation of the ink droplets on the surface of the fabric, and also needs to be tailored to the equipment used.


As previously mentioned, the viscosity of the ink, together with the surface tension, affects the formation of ink droplets.

The high viscosity causes the broken tail to be stretched and drawn in a draw shape; if the viscosity is too low, the droplets are easily broken.

Another important parameter that is affected by viscosity is the jet velocity of the droplets. If the viscosity is too high, the droplet velocity will decrease and even the ink droplets will not hit the same point on the substrate being printed.

Basic tests and actual printing results have shown that a viscosity of less than 10 mPa·s (preferably 2 to 4 mPs·s) is a suitable range for obtaining a satisfactory droplet shape and printing effect.


In continuous jet printing equipment, the ink droplets are deflected by the charge, so the ink must have the ability to be charged and electrically conductive.

The ORIC printing machine requires an ink conductivity of 750 siemens or more.

In fact, as an aqueous ink system, it has good electrical conductivity. It is only necessary to add a special conductivity modifier in a solvent-based ink system. Studies have shown that the effect of conductivity on droplet formation has not found a significant dependence.

PH value

The pH of the heat transfer ink should be stable. Some dyes will precipitate due to changes in pH. Generally, the pH should be adjusted at 7~8. The ink is acidic and will corrode the nozzle and metal parts. A suitable pH value facilitates the combination of dye and fiber reaction and promotes print clarity.

There are other technical requirements for inkjet printing inks, such as good dyeability, so that the color of the fabric is high; the purity of the dye is high, so as to ensure the vividness of the color; the thermal stability and the frost resistance are good, so that the storage Stability can be improved.
