Can a cheap UV flatbed printer be purchased with confidence?

UV flatbed printer

I believe that when many customers buy UV flatbed printers, they clearly feel that there is no difference in configuration. Why are the prices so different? The expensive UV flatbed printer costs tens of thousands of dollars, but the cheap ones only cost thousands of dollars?

Below I will discuss with you what is the cheap UV flatbed printer? Which cheap printer can buy?

When we buy a printer, we must first exclude used printers and modified machines. Although this type of digital UV printer is very cheap, it cannot be used. Because you buy a flatbed printer to make money, not to lose money to repair the machine often.

Because some UV flatbed printer manufacturers use inferior or have some used print heads after modification, you will find it will not be used after a period of use. So the price of UV printers will be much lower. So, one point for the price!

UV flatbed printer

The reason why the UV flatbed printer is cheap is nothing more than the following:

1. The hardware used is cheap.
These UV flatbed printers use some poor quality and inexpensive hardware. They simply removed some of the damaged internal hardware, changed the bottom Y-axis drive, added a few hundred dollars of LED lights and several ink cartridges worth more than a few dollars to complete the hardware modification.

2. The software used is cheap.
This type of UV flatbed printer uses an unknown printer board and system, just to make some changes in the content, without spending thousands of dollars to buy a special board for UV flatbed printing machines. This will cause the machine to always go wrong, and it is not acceptable to use it for mass production.

3. The overall cost is low.
The manufacturers of such UV flatbed printers are basically small workshops, do not have to bear corporate rents, taxes, and do not have to provide corresponding after-sales service, basically a hammer sale. Overall, the operating costs of such digital UV printer manufacturers are very low, which in turn causes their product prices to be extremely low.

4. No supporting services.
When purchasing UV flatbed printers, there are many supporting services for regular UV flatbed printer manufacturers. Such as providing a library, providing operational training, providing consumables, providing comprehensive after-sales service and corresponding prepress and post-press processing solutions, etc., but they do not.

In summary, I think everyone knows why some UV flatbed printers are so cheap, so you dare to buy such UV flatbed printers?

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.

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.

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.

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!

Mistakes in speed of UV flatbed printers

uv flatbed printer

There are three main misunderstandings of UV flatbed printer speed: theoretical speed, speed in different modes, and actual production speed. What needs to be understood is that the speed in most sales outlets only refers to the theoretical speed. A small number of professional ones will mention the speeds in different modes, but these are not actual production speeds. The gap between them is at least calculated by times.

UV flatbed printer theoretical speed:

Refers to the printing speed that the device can achieve in the limit mode, regardless of the accuracy, does not consider the manual loading and unloading, but also can be barely realized in the special printing mode. For example, it is often said that it is impossible to achieve 60 square meters, 80 square meters, etc. in one hour.

UV flatbed printer speed in different modes:

Refers to the speed in a few pass print mode, this is actually not allowed. Although the larger the pass value, the slower the speed, but the factors affecting the amount of feathering, single bidirectional, loading and unloading, rubbing coating or alcohol, etc., can not be realized in actual printing.

UV flatbed printer actual printing speed:

It refers to the printing speed that is integrated in the actual production process, taking into account the accuracy, considering the manual loading and unloading, taking into account the factors such as wiping alcohol or coating.

How to improve the actual printing speed of uv flatbed printers as much as possible:

1. The configuration of the upgraded uv flatbed printer includes not limited to: increasing the speed of the print head, replacing the higher performance print head, selecting the double row print mode, and the like;

2. When selecting a larger format device so that the uv flatbed printer prints a full part, the processing of the back material is performed simultaneously, so that after printing the latter part of the material, the material of the front part is replaced, and the machine is continuously printed.

3. The details of operation: choose a reasonable print mode, feathering settings, drawing efficiency, etc., these are affected by the level of different uv flatbed printer technicians.

Is the higher the print resolution of the UV printer, the better?

uv flatbed printer The print resolution of the uv printer determines the fineness of the printed image, which directly affects the quality of the printed product, and is also an important indicator for judging the print quality of the printer. The higher the resolution, the clearer the printed pattern is. In the current office, there are more and more types of printed documents. At this time, the user needs to consider whether the print quality of the printer can be satisfied in addition to the print load and speed. Your own requirements.

uv flatbed printerWhen the UV flatbed printer is working, set the print resolution to be based on the actual situation, not the higher the better. For example, the highest output resolution of the printer is now 2880×2880dpi. In theory, 2880 dots of ink will be placed in the horizontal direction of the material in the horizontal direction. Because the material may be too saturated with the absorption of ink, the ink is connected into one piece. Instead, the print resolution is reduced. Therefore, the theoretical point refers to the capacity limit that UV printers can achieve, but in fact, it depends on the cooperation of materials. The better the ink absorption of the material, the more independent dots can be placed in each inch. If the material used does not support the highest resolution selected, adjacent toner dots will merge into one piece, which will affect the printing effect.

uv printerIf the UV printer wants to avoid the above factors for the highest resolution printing, it is necessary to perform coating pretreatment on the surface of the object to be printed. The role of the coating is to absorb ink, adsorb and carry the ink, so that the ink droplets perfectly present the image on the coating, so the larger the DPI value, the finer the printed pattern and the better the effect. If the material is printed with high precision and the ink is scattered, or the outline of the image is blurred, it is related to the carrying capacity of the coating, and it is necessary to replace the suitable coating.

The above is the answer that I brought to you about the question “Is the higher the print resolution of the UV printer, the better?”, I hope to help everyone.
