Can Uv printers print everything?
What materials can Uv printers print?

Uv printer is a new type of direct digital printing technology developed in the past ten years. It is a non-contact inkjet printer that prints the desired pattern directly on the surface of the product through computer control. The uv in uv printers are the abbreviation of ultraviolet light, that is, the ultraviolet light emitted by the LED lamp, so that the printed product is dried during the printing process, and the pattern is not blurred.

Uv mainly consists of three aspects, namely ink, curing principle, and printing.

uv printersInk: Unlike previous water-based inks, textile inks, oil-based inks, and solvent-based inks, the new generation of equipment uses uv ink. Uv ink itself is between solvent-based and oil-based inks. It is a chemical ink with a slight Corrosive, so in daily use, try to avoid contact with the body. What needs to be understood here is that uv ink is divided into three grades, one is made in China, one is produced by the original print head, and the other is imported.

Curing principle: The curing method adopts the principle of internal cooling and solidification in a very short period of time, which does not produce odor, does not generate heat, and does not generate bubbles. This is mainly determined by the photosensitizer present in the uv ink.

uv printersPrinting: Direct piezoelectric inkjet printing, the print head is inkjet printing between 12.5px and 25px from the material, and the uv ink is directly sprayed on the surface of the material, and then irradiated by the LED lamps on both sides of the print head. Achieve drying of the ink. The uv printers produced by Andersen are also able to meet the high quality image output requirements of many industries.

Wide range of applications: Digital uv printers have a wide range of printing materials, such as: reflective film, canvas, glass, wood crafts, ceilings, aluminum alloy panels, wood panels, acrylic panels, plexiglass, corrugated panels, plastic panels, resin panels, plasterboard, Digital housing, etc.

How to maintain uv flatbed printer in summer hot weather?

In summer, both temperature and humidity will increase dramatically. People need to prevent heat stroke and summer heat. And our equipment needs to be maintained in the hot sun.In this issue, based on years of experience, I shared five ways to maintain a UV flatbed printer in the summer.

uv flatbed printer

Method 1: Temperature control.

The uv flatbed printer should be placed in a cool, backlit corner to avoid high temperatures and direct sunlight. Suitable indoor temperature is 19 ° C ~ 32 ° C, humidity is 25% ~ 70%.

Method 2: Power off and moisturize.

When uv flatbed printers do not work for a long time, you can choose to moisturize after power off, do not let the machine exit the standby state, so the temperature will rise.

Method 3: Always check the print head.

After turning on the wide-format uv flatbed printer every day, be sure to test the strip first to see if the sprinkler is clogged. The summer temperature is too high and the ink is easy to dry.

Method 4: Clean the uv flatbed printer weekly.

Once a week, clean the inside and outside of the equipment. Especially in key locations such as noses and rails, it is especially important.

Method 5: The position of the flat line must be viewed daily when it is turned on.

Make sure that the surface of the print head line is clean and that the connecting rod is tight and not loose.

The reasons and solutions for uv printer flying ink and cross color

The main reason for uv printer flying ink and cross color:

For static electricity, if the uv printer is in a low humidity environment and the environment is dry, static electricity is easily generated between the print head and the material, so that ink flying may occur during the printing process.

If the voltage of the print head is too high, if the voltage displayed on the head of the print head is bright red and alarm, the flying ink will appear during the use.

When the uv printer is used for a long time, there will be a situation where the machine print head is broken, which will inevitably lead to the machine flying ink.

The electronic control system controls the pulse interval of the printing head to be unreasonable.

The electronic control system controls the pulse distance between the ignition of the printing head to cause the flying phenomenon.

The print head is too high. Generally, the height of the print head and material should be between 1mm and 20mm. If the print head exceeds the range of its own spray, it will definitely fly.

Solutions:

✔For flying ink caused by static electricity.You need to add an electrostatic bar or add a ground wire to shield it.

✔The print head voltage is too high.You need to modify the circuit board, or change the circuit to avoid this problem.

✔ Print the test strip and check the condition of the print head. If it is found to be blocked or faint.And you need to clean the channel of the print head to keep it open. The solution to the disconnection of the print head needs to check the condition of the print head frequently to see if there is any illusion or blockage. If it needs to be processed immediately, the flying phenomenon cannot be avoided.

✔Electronic control system problem, this requires special technicians to carry out maintenance to solve.

✔The distance between the print head and the carrier is too high, so it is easy to solve them by shortening their distance.

Uv printers have some shortcomings, but it does not affect his popularity, because its biggest advantage over traditional printers is that the printing material is not subject to any restrictions, enabling direct printing, one-time imaging, and its printing effect far exceeds the traditional printing effect, can also achieve the embossed personality customization effect, eliminating the need for past repetitive processes such as plate making, filming, color registration, etc. Nowadays, the products are more and more complicated, but no matter how complicated, uv flatbed printer can realize once. Printing, what companies are pursuing is creating value for users far beyond the price of the machine itself!

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?

uv printer

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.

What are the classifications of UV printer coatings?

The UV flatbed printer uses a combination of LED UV light + oily ink, which can theoretically be printed and attached to any flat material. But there are also some special materials because the surface is too smooth, such as acrylic, glass, ceramic tiles and so on. They produce prints that are dark and easy to fade. How to solve this problem? It is the use of a special chemical called coating, but the coating is not universal on a variety of substrates. The UV printer coating is a coating for the substrate and ink, a substrate, taking into account the properties of the ink. What are the classifications of UV printer coatings?

There are many types of UV flatbed printers, such as metal coating, ABS coating, leather coating, silicone coating, glass coating, PC coating, etc.

uv printer

The common UV printer coatings are as follows:

ABS print coating:

There are many kinds of ABS coatings, suitable for wood, kraft, PVC, ABS, gypsum board, acrylic, PS, plastic and so on. Available in both clear and white colors, it has both a bright and matte finish.

Metal Print Coating CP:

Metal, dry a little. Requires a thick surface DY: metal, ceramic, slower than CP. Applicable to aluminum, tinplate, copper, aluminum alloy and other materials, tempered glass, special treatment is required. Available in both transparent and white colors, it can be used for both bright and matte effects. Mainly the smoothness of the surface, like ceramics are smoother than glass, then use DY.

Silicone print coating:

Suitable for materials such as silicone rubber. Poor surface activity, need flame treatment, otherwise the adhesion is not strong, the surface should not be sprayed too thick, otherwise it is difficult to dry.

Glass print coating PL:

Applicable to tiles, machine glass, tempered glass, ceramics, crystal, but special treatment is required. Available in both transparent and white colors, it can be used for both bright and matte finishes. Need to be boiled, can be equipped with white oil. Adhesion is very important, white oil can not be too strong, otherwise the pattern will be dissolved, spray twice better.

Leather print coating:

Applicable to PVC leather, leather, leather, PU leather, etc., both transparent and white, can play bright and matte effect.

PC print coated PC:

It is a hard material and in most cases the adhesion is not easy to pass. Applicable to materials beginning with P, such as PS, PP, PVC, etc.

UV printer

In fact, there are many items that can be printed directly without coating, just to see the customer’s demand for printing results. Like ordinary plastic, PVC, mobile phone case, PE film, etc., can be printed directly with UV printers. As far as the current situation is concerned, UV printers can conquer most materials. And UV printing technology will also advance by leaps and bounds in continuous research and development. Efforts to make UV printer technology more perfect, so that more materials save the coating process, making printing easier!
