How Does UV Digital printing machine Solve Problem of odor generated from Varnish？

A. uv varnish odor is not completely dried and cured.
Solution: You can reduce the printing speed or increase the light power.

B. uv printer ultraviolet lamp aging or inadequate.
Solution: Replace and select the appropriate UV lamps. Currently high pressure mercury lamp offers the average life as 1000 hours. with time going by, the electrode is gradually decomposed to produce tube deposition, then transparency and UV transparent rate will gradually decline.Therefore the lamp should be on a regular detection and  promptly replace the faulty lamp to ensure complete curing UV ink.
In addition, taking UV lamp properly must be noted. It should not hold the quartz glass body of UV lamp.Otherwise, the grease on the skin will adhere on quartz glass; it only can hold the ceramic end, or with non-wearing hemp Cloth gloves to hold. Whenever touch UV lamps, the grease can be cleaned with an alcohol solvent scrub.

C.the antioxidant interference uv Varnish printer uses is poor.
Solution: strengthening workshop ventilation and exhaust (air) system.

D.uv irreactive diluent in Varnish of printer are too much.
Solution: UV Varnish types must be replaced when necessary.
UV Varnish is transparent,so shine ultraviolet light can go through from the top to end without any obstacles.
When test quality,you can awab the varnish on ordinary white paper or white cardboard surface with a brush. The coating thickness is about 0.5mm or slightly thicker, placed under UV light to cure. If the coating surface without any bubbles after curing and the surface smoothness is very good, indicating good quality of UV varnish you purchased.

Is UV Ink Poisonous of UV Flatbed Printers？

UV ink is also called as universal ink.It can print on various media.There are so many chemical components. Usually, UV flatbed printers are depend on the electric field force between print heads and media to print ink on certain area of media.Inkjet ink can be called as blood of ink system.The quality of ink is directly related to the printing output quality, sometimes even directly influence the smooth printing process.
The general feature of UV ink is stable curing performance,which will not damage the print heads and some metal parts.And it will not be damaged by bacteria.It's hard to be burnt out and color fading.If the jetting and drying performance are good enough and it doesn't clog the print heads and dry on the ink tubes,but it can print on various media.Density,adhesion and tension of ink meet the requirements of digital printing. Because ink density will influence the colors of printing while adhesion and tension decide the smooth printing process.
UV ink is not solvent ink,which is dried quickly,colorful and water-proof.Now UV ink is with mature ink technology. The pollution output is almost zero.According to survey,as for ink,annual production of Japan is about 16,000 tons,that of Europe is about 18,000 tons and that of North America is about 19,000 tons.

As for UV flatbed printers, louder noise means higher friction among parts,which also means that the damage of printers will be bigger. At the same time,louder noise means that there is something wrong in design,assemble and coordination among parts,which may influence the service life of UV flatbed printers.
So while choosing the flatbed printer, clients can listen to the sound of working printers to compare the noise,then clients can have something in mind to decide the printers.
