Glass decoration:

Glass has many kinds: white glass, tempered glass, frosted glass, etc. Normally printable glass has coating layer, which can solve the problem of adhesion. After the coating layer dry, you can use the UV printer Just print, then dry, with bright colors and high-end atmosphere. Glass applications: background walls, entrances, sliding doors, coffee table panels, 3D crystal jewelry, etc. The tempered glass needs to be printed after tempering, otherwise, the pattern will fall off when tempered in the tempering furnace (the tempering furnace is around 700 degrees). Nowadays, The popular color + white + color printing solution, manufacturers can print double sides of glass, and the pattern effect on both sides.
Glass products are suitable for people: home improvement, tooling, school, hotel, KTV, restaurant, tea house, facade room, etc.

What will affect actual UV printer print speed?

Three main factors that affect actual printing speed of UV flatbed printers:
1. Loading and unloading time:

According to a standard plate in the advertising industry, it usually takes 4 minutes to accomplish prints. For example, Assuming that the 2513 UV flatbed printer production mode is calculated at a speed of 16 square meters/hour, one standard plate will take about 12 minutes, adding 4 minutes of manual loading and unloading, it takes 16 minutes, and only can print 4 standard sheets in one hour.

2. Pre-printing process:

some materials need to wipe the coating before printing, some need flame treatment, some need to wipe alcohol, etc., these will affect the actual printing speed of the UV flatbed printer, thence, we should pay more attention to these factors.

3. The stability of printer and the technical level of staffs

Firstly, printer manufacturers are in charge of the former, and there is a big gap between different manufacturers. Some cheap UV flatbed printers have a minor repair in three days and a major repair in five days. Some need 2 to 3 months to repair. Besides, the technical level of staff: drawing efficiency, software operation efficiency, etc. It is necessary to choose skilled technicians so that we can reduce scrap rate a lot.

How to improve the UV printer actual printing speed?

1. The configuration of upgrading the UV flatbed printer includes: increasing the speed of the print head, replacing the higher performance print head, selecting the double-row printing mode, etc.;

2. When choosing a larger format device to make UV flatbed printer print a full part, The processing of the latter materials will carry out simultaneously, therefore,  when printing  the latter part of the material, we can replace the previous part of the material to realize the non-stop printing.

3. Detailed operation: choose a reasonable printing mode, feather volume setting, drawing efficiency, etc., To some extent, different level UV printer technicians will affect it.

Tip of UV printer maintenance in Winter

When it gets cold in winter every year, the number of failures of UV printers will also increase, mainly in four areas: print head nozzle blockage and disconnection, consumables solidification and condensation, electrostatic interference, and voltage instability. In view of these situations, how to prevent them in advance.

1. The print head blockage and disconnection.

After the temperature drops in winter, the print head will block and disconnect. Don’t worry too much. This is mostly because the viscosity of the UV ink increases and the fluency of the ink decreases after the temperature drops. Individual print heads do not emit ink smoothly.

Solution: In addition to the automatic stirring and heating of conventional large ink cartridges and secondary ink cartridges, heating plates can be installed on both sides of the ink outlet of the nozzle. If it is not convenient to install, you can choose a small sun and keep 30cm Distance, illuminate the head car, if possible, you can turn on the heating or air conditioning to keep the working environment temperature of the UV printer above 25 degrees.

2. Consumables are solidified and condensed.

Users of UV printers found that the ink in the UV ink bottle has become viscous, and some of it has condensed. When this happens, it means that the ink has been scrapped and cannot work, mostly because the ink bottle is placed directly on the ground.

Solution: The storage of consumables in winter must be placed on the shelf, not on the ground, and not in the open air.

3. Static electricity interferes

The direct effect is that the ejected ink droplets deviate from the direction due to static electricity, causing the phenomenon of “flying ink” or “ink splashing”, and the print quality will be seriously reduced. In severe cases, it will cause the circuit to burn down.

Solution: In addition to installing the necessary ground wire, the cleaning of the working environment of the UV printer requires 2 days/time for maintenance to reduce dust. If the air is dry, just turn on the humidifier. If possible, an electrostatic rod can be installed on the machine to eliminate the electrostatic interference of the material itself.

4. The voltage is unstable.

In winter, due to the heating demand, a large number of electrical appliances will be turned on, and the current and voltage will be overloaded. These instabilities will affect the normal operation of the UV printer in the light of it, and will directly burn the internal circuit.

Solution: In addition to choosing a UV inkjet printer from a regular manufacturer (the circuit system has preventive and emergency solutions), a voltage stabilizer must be installed, a backup power supply and a separate line for the equipment must be installed. It cannot be mixed with other electrical appliances.

What can affect UV prints visual effects?

The visual effects of UV printing include plain ordinary color printing, 3d, 4d, 5d and other three-dimensional effects. Among them, normal color printing includes two-color, four-color, six-color, eight-color, eleven-color and so on. The more spot-color UV ink, the more delicate the pattern display.

The factors that affect the visual effect of UV printing are:
1. The physical accuracy of print head

It refers to the number of ink droplets in the nozzle hole. The smaller the value, the higher the accuracy and the finer the printed lines; for example, Toshiba ce4 print head (5PL) <Ricoh gen5 print head (7PL) <Seiko gs508 (12PL) and so on. If you look at it from a long distance outdoors, you can use a large-aperture nozzle, and if you look at it indoors, you can use a small-aperture nozzle.

2. Physical accuracy of UV flatbed printer

It refers to the physical error between the core components such as the screw rod, the trolley, the motor, and the platform. The smaller the value, the better the printing accuracy of the pattern can be guaranteed. When selecting equipment, users should check the brands of parts and understand their process and performance indicators.

3. Patterned pixels

The format of pictures printed by UV flatbed printers generally uses vector graphics, such as PSD, tiff, ai, etc. The pixels should be larger than 300dpi, the higher the effect, the better.

4. Adjustment of color curve

The color curves used in different application scenarios are different. Especially in the advertising industry, the impact of color difference is relatively large. This depends on the curve used by the UV flatbed printer and the adjustment of the technician;

5. Printing software settings

For example, select a few passes to print, the larger the value, the better the effect. Feather opening value, white ink printing ink volume, embossing parameter settings, etc.

6. The characteristics of the material itself

Some 5d and 6d effects on the market require the material itself to be multi-faceted, so that it looks like a 3d effect from multiple angles.

7. Color matching

Under normal circumstances, the standard UV flatbed printer is CMYK + W, which can meet 90% of the demand. However, some export or high-end needs can only be realized by using six, eight, or even eleven colors. The more colors are used, the more layered and delicate the pattern becomes.

Why Ricoh GEN5 head hot on UV printers?

When buying a UV printer, what kind of nozzles does everyone would like to choose? At present, there are UV printers modified from Epson original nozzles on the market, including Konica nozzles, Seiko nozzles, Ricoh nozzles, etc. The most popular is Ricoh nozzles. Why?

EPSON print head:

Firstly, Japanese ESPON print head has always been an independent leader in the era of Japanese inkjet machines. You can see EPSON print heads in MIMAKI, ROLAND, MOUTH and other series of Japanese inkjet printers. At present, domestic wide-format inkjet printers have also begun to use Espon DX5/ DX7, lead domestic printing machines. For example, our piezoelectric printing machine manufacturers such as ORIC, KEUNDO, ALLWIN series indoor and outdoor piezoelectric printing machines use high-performance and high-precision Epson DX5 piezoelectric nozzles.

Konica print head:

Konica nozzles are double-row ink inlet pipes with uniform flow and pressure. Ensure print quality. Some brands are single row. 512 Konica nozzle is a fully enclosed nozzle, waterproof and anti-aging. Konica nozzles have poor compatibility with inks, have strict requirements for inks in different seasons, and are sensitive to environmental temperature changes. When plate of the nozzles exposing outside, and ink will burn the nozzles. It is easy to break ink when working at high and low temperatures. The life span is less than 1.5 years.

RICOH print head:

High-end industrial UV printers normally use Ricoh print heads. For example, most of one or two million imported branded machines use Ricoh print heads. The same industrial nozzle machine, Ricoh’s printing effect is absolutely the best, the clearest, can basically achieve Epson printing effect. Double-row ink inlet, fine ink dots, grayscale printing. Fully enclosed print head, waterproof and anti-aging. Ricoh Gen5 print head has a built-in constant temperature system. you can adjust voltage with temperature to obtain a more stable printing state. The circuit board of the print head is all metal wrapped, which can soak the ink without causing damage to the print head. Besides, The print head has a long spanlife and normally can use for 3-5 years. It is the most successful piezoelectric print head. Single sprinkler with single-color control, all-steel structure super corrosion-resistant sprinkler, both speed and effect, but its disadvantage is that the price is more expensive than other types of sprinkler machines.
