What’s The Advantages & Maintance of Uv Flatbed Printer?

Uv printer is essentially a type of piezoelectric inkjet printing device.
The picture that is shot has a bumpy feel. This is called embossed in the industry and is formed by stacking and printing of white ink.
The ink can’t see the light because the uv ink itself can react with the ultraviolet light in the sunlight, causing it to solidify. Therefore, in the process of storage and transportation, a black bottle is needed to avoid contact with sunlight.

UV flatbed printers The advantages of UV flatbed printers, from the actual production feedback:
1. Save labor. Compared with silk screen printing and transfer printing, if you print with uv, one person can finish printing, and the side will reduce the labor cost for the enterprise; after computer control, after the equipment is automatically printed, one technician will Can complete the entire printing process without hiring more employees
2, pollution reduction, compared to weak solvent, silk screen that is unpleasant pungent smell, although uv ink has a stimulating smell, but has greatly reduced pollution.
3, short version of personalized printing This piece of outstanding advantages, if you want to print any pattern, you can directly through the ps software to map.

Daily maintenance of uv flatbed printer:

1. The equipment should be used at least once every three days. If it is not used for 7 days, it needs to moisturize the nozzle. If it is not used for more than 7 days, the nozzle should be removed and cleaned.

2. The water tank should be used every 3 Need to replace the purified water once a month;
3. The beam guide and the Y-axis guide rail need to be lubricated every other month to prevent rust;
4. The ink path system is recommended to be replaced once every six months to prevent the ink from depositing and depositing damage to the nozzle and affecting the printing effect;
5, the device needs to check the color every 1 month to ensure good printing results.

Why does the sublimation inkjet printer’s printhead “strike”?

The printhead is the heart of a wide-format inkjet printer. If there is a problem with the printhead, the entire machine will not work properly. Therefore, be sure to protect the print head when using the printer. So what conditions will affect the normal use of the print head? Today, I will come to give you a glimpse!

printhead

First, the airtightness between the ink cartridge, the ink tube, and the printhead.

I have previously talked about the inkjet principle of inkjet printers. Everyone knows that the printer printhead is controlled by the microvoltage change of the negative pressure system to control the ink output. To make the nozzle smoothly ink, it is necessary to ensure the inkjet system. Absolutely sealed. When the voltage is increased, the pressure of the micro-voltage to the ink tube will increase, and a pressure difference will be formed inside and outside the ink tube, and the ink will be pressed from the ink cartridge into the ink tube to the print head. If the inkjet system leaks, the negative pressure system can’t play its due role. If the ink can’t reach the print head, the print head will naturally not emit ink!

Second, the ink cartridge is leaking.

A small amount of air is always present in the upper part of the print cartridge connected to the continuous ink supply system, in order to avoid the phenomenon of ink self-flow caused by the siphon principle. However, if there is an air section in the entire inking line, it is caused by the air leakage of the ink cartridge or the unsealing of the ink injection elbow interface, so the air leakage of the ink cartridge may cause the ink to be discharged or the ink drop.

Third, improper operation.

The ink from the print head ejects ink through its orifice. Since this orifice is small, it may be clogged or damaged with carelessness.

During the printing process, some materials have poor adhesion, and we use a fixing agent to enhance their adhesion. Fixing agent is a very viscous solvent. Once it sticks to the nozzle, the nozzle will be blocked or directly scrapped, which will not work properly.

Fourth, the impact of external factors.

For example, when carrying or using a printer, the machine is hit by an external force, causing the printer to not work properly.

Tips:

1. When using the sublimation inkjet printer, remember to follow the printer instructions strictly!

2. When the printer can’t print normally, don’t panic. Check carefully whether the printer spare parts are in good condition and make other judgments!

How to Maintain Your Large Format Eco-solvent Printer?

If you want to make the large format  machine use twice the result with half the effort, usually pay attention to the daily maintenance of the it, especially the outdoor large format machine, that is, we often say that the maintenance of the weak eco-solvent printer machine must be done better than the maintenance of the indoor photo machine. We also spend a lot more.

large format printer Since indoor wide format machine outdoor large format  machines are classified according to different advertising use environments, the related inks used are also different. The indoor photo machine uses water-based ink, and the water-based ink is generally suitable for indoor advertising image screens. It is not waterproof and is exposed to long-term glare. If it is like an outdoor environment, the water-based ink will easily fade, and the storage time will not fade easily. However, due to the characteristics of the water-based ink of the indoor photo machine, the maintenance of the nozzle is lower than that of the weak eco-solvent printer.

Outdoor wide format machine, using weak solvent ink, weak solvent ink has certain waterproofness, and the printed image is used in different outdoor climates, such as sun and rain, etc. It is a characteristic of a weak solvent ink. However, due to these characteristics, it is also a problem that requires attention to daily maintenance of a weak solvent photo machine.

Before using the large format printer every day, it is recommended to print the nozzle test strip to check whether the nozzle is clogged. If there is any blockage, please perform the cleaning operation to ensure that the nozzle is in good condition.

If the large format printer is deactivated for more than 3 days or more, please clamp the two ink tubes under the ink stack cap with the clamp before stopping the machine, and add some cleaning liquid to the ink stack cap to ensure that the surface of the nozzle is wet. , effectively protect the nozzle.

 

If the large format eco-solvent printer needs to be idle for a long time, please keep the protective cover for the machine during the idle period of the machine to avoid dust pollution. Also, please put the machine in a safe position to avoid the cause of rodent, insect and other abnormal wear and tear. The machine is damaged.

Pay attention to the fireproof, waterproof, anti-theft and other work of the machine storage room to avoid damage or loss of the large format printer, computer and RIP software!

The role of suction system in piezoelectric inkjet printers

piezoelectric inkjet printersIn the printing process of piezoelectric inkjet printers, I believe that everyone has noticed that there are many regularly distributed small holes on the flat sheet metal platform. These holes are used as the suction platform for piezoelectric inkjet printers. At the same time, the fan under the platform is combined to form the suction system of the printer.

In the printout of a wide-format inkjet printer, the suction fan blows forward and the rear air replenishes. In this way, a strong air flow is formed behind the fan, and a small suction force is generated through the small hole in the platform to suck the printing medium. The high speed operation of the fan creates a difference in pressure between the top and bottom, which makes the print medium close to the printing platform, ensuring that the print medium is flatter throughout the printing process. This is the complete process of the suction system working in our digital inkjet printing machine.

piezoelectric inkjet printersSimply put, the function of the suction system is to ensure that the print media and the printing platform can be closely fitted to ensure that the printing can not be arched, so that the sublimation textile printer prints more smoothly and smoothly, and the drawing effect is better.

In addition, because the horizontal tensile properties and toughness of different materials are different, for materials with small horizontal tensile properties and poor toughness, only a small suction force is required to keep the material flat. If the suction force is too large, the printing medium will not move. This affects the printhead. For a harder material, if the suction is too small, it will cause the material to be flat due to insufficient suction, thus affecting the printing effect. Therefore, the suction system in a wide format printer is essential during the printing process.

The ORIC series of piezoelectric printing printers are designed with suction and heating in one design on the suction platform. At the same time of printing output, it is also possible to increase the drying speed of the ink moderately, so that the final print quality of the printer is more vivid and realistic, and is widely loved by customers.

What is the difference between oily inks and water based inks in wide format inkjet printers?

Wide-format inkjet printer inks are an important factor in printer operation, and different types of inks print different effects on the printer. Thus, the ink used in the wide format inkjet printer differs from oily inks and  water based inks.

1.Water based ink
water based inksThe water-based ink for wide-format inkjet printers is mainly composed of water and a water-soluble solvent as the main component of the dissolved chromophore. The biggest advantage of water-soluble solvents is that they are harmless to the human body and the environment. Therefore, water-based inks are also called environmentally friendly inks. Water-based inks are generally produced using nano-scale pigments, which overcomes the sensitivity of dye-based inks to temperature, humidity, atmospheric conditions, light effects, etc., and achieves the ideal effect of waterproof, light-resistant and UV-resistant.

2. Oily ink
The oily ink is a main component based on an organic solvent (for example, toluene, xylene, etc.). Compared with water-based inks, oil-based inks have a relatively high odor and are generally used in outdoor printers. Secondly, the ph value of the oily ink is generally acidic due to the water-insoluble pigment ink raw material used.

Simply put, the biggest difference between water-based inks and oil-based inks is the different areas of use. Water-based inks are often used in indoor advertising, requiring high color saturation and printing accuracy for printing. Oily inks are used outdoors to combat areas where UV, temperature and humidity are more demanding.

water based inksSome wide format inkjet printers on the market now support water and oil compatibility. However, it should be noted that water-based inks and oil-based inks cannot be mixed in the same print head. Water-oil compatible means that wide-format inkjet printer equipment can use water-based or oil-based ink consumables in the case where the print head, ink cartridge, and ink tube are completely dry, clean and free from contamination.

In addition, although ink is a consumable, it is also an important component for wide-format inkjet printers. Inferior inks can easily affect printer print quality. Therefore, when choosing a wide inkjet printer ink, it is recommended to choose the original printing ink to ensure the stability of the wide inkjet printer printhead and system.
