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.

Viscosity

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.

 Conductivity

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.

Common problems and solutions for garment printing?

With the arrival of summer, many heat transfer practitioners have begun to make garment printing. For some experienced friends, the production of clothing printing is relatively simple. But often for some novice friends, clothing printing is still relatively easy to appear a variety of small problems, below, on the editor of the digital printing factory, to introduce the common problems and solutions of clothing printing.

1. The situation of yellowing after garment printing is relatively common, and the reasons that often cause this phenomenon are as follows.

1). Heating time is too long. As we all know, after a long period of high temperature, the clothing will appear yellow. This is mainly determined by the material of the garment and is not unique to thermal transfer technology. Therefore, everyone must pay attention to the time in the production of clothing printing. Usually 20 seconds -25 seconds is enough, don’t increase the heating time privately because you are afraid of the transfer is not complete.
2). The clothing printing has a high cotton content. Many friends are not very familiar with the cotton material. In fact, the clothes we usually see are often low in cotton content, generally 80. The less the amount of cotton, the less likely it is to yellow during the transfer process, but if it reaches 130 or more, everyone should pay special attention to it, and the phenomenon of yellowing of clothing printing often occurs. Therefore, when you choose clothing, you must choose the right one, and do not blindly pursue the cotton content.

2. Image peeling after clothing printing is also common, and most of this problem is caused by the quality of clothing printing paper.

Apparel printing paper must choose some more reliable companies, do not want to be cheap, with some small manufacturers or clothing printing papers of companies that are just beginning to do heat transfer, often cause the loss due to the quality. We generally use Korean-made clothing printing paper, which is recommended for transfer and firmness. Another situation is caused by insufficient pressure on the heat press machine. In fact, this is also a quality problem, so as with the above, if you don’t explain much, you can check it out on the website of FeiYue Digital Technology Co., Ltd.

3. After the clothing printing, the clothing printing is actually no different from the ordinary t-shirt.

It is necessary to pay attention to the fact that it is not exposed to ultraviolet light for a long time (the ink is easily decomposed). When not wearing it, put it in a dry environment to avoid image loss caused by moisture.

The above is basically some of the problems that people often encounter in making garment printing.

Four Manufacturing Methods of Customized T-shirts

If you’re considering purchasing custom made shirts for an event or a team, you should understand the possible methods used to get what you want. With computer technology adding to the older existing methods, you now have many choices. Which type will work best will depend upon several factors, including what you want done and which method a professional printing company like ORIC offers.

Creating Custom Made Shirts: Silk Screening or Printing

This is by far the most common way used to create custom made shirts, and it’s perfect if your design only requires a couple of different colors. It is also for those who want their design or lettering to have a raised feel and appearance. The advantages of this method for any producer include speed and cost-effectiveness. You will be wowed by the durability of the imprinted designs, as well as the vivid colors.

Embroidery

If you have a dress, shirt, hat or jacket on which you want to place a specific image or lettering, companies such as ORIC suggest a technique called embroidery. This is either done by hand, or by using a specific machine. T-shirts may pucker as a result of the process, which may limit the bulk production of custom-made shirts. The cost is also a factor in reducing its overall popularity.
Nevertheless, if you want something embroidered, it can be done. Simply stick to smaller designs. Alternatively, ask whether you can combine this method with silk screening to achieve a unique design.

Digital Printing

Technology has resulted in many advancements in printing. Among them is the now common Direct-To-Garment (DTG) digital printing. It is subdivided into two types:

  • Dark Direct to Garment Printing: This is an expensive form of DTG printing, and a variation on light DTG digital printing. It can successfully achieve a colorful image on a black t-shirt without the use of appliqués or iron-ons.
  • Light Direct to Garment Printing: It does not use white ink, and it is best if you choose light colored custom made shirts. The color choices are amazing and very numerous.

Unlike with a few other methods, DTG custom made shirts do not crack or peel as time passes. The ink remains solid as it is embedded into the fabric of the shirt.

Heat Transfers

If you have an image in mind, one that is readily and commercially available, one of the more common methods to transfer it to custom made shirts is through heat transfers. Heat and pressure are the basic requirements to successfully transfer the image. If this is a method you’d prefer, first make sure you or your company chooses an expert in the field. The results can vary, and you could get crooked images and wrinkled t-shirts resulting from someone who is less than professional.

If you’re planning on a single design, or want to create a uniform look for a group by applying a log or image to custom made shirts, consider and weight your options. Be sure to talk to someone who knows the different methods, such as the professionals at ORIC. Listen clearly to what is said, do your own research, and only then go ahead with your plans.
