Frequently Asked Questions
What are the benefits of UV printing for printing shops?
Nowadays, you must be used to seeing new processes and technologies come and go in the printing industry, which you once wondered if they are suitable for your business. The UV printing technique is one of the new processes mentioned above.
Following are the features of uv printing technology
UV ink is able to bond onto a variety of surface of the materials from flexile to hard, including canvas, banner, vinyl,leather, CDs, plastics, metal, glass, ceramic, even concrete.
UV ink cures instantly by curing system installed on the machine, which ensures high productivity for the requiements of fast delivery. No need additional pre-coating, laminating
UV cured ink is very environmental , it can be used indoor or outdoor for POP, graphic sign, poster, vehicle wrap, building wrap and cabinet ect. No need worry about volatile organic compounds into the atmosphere.
Saving pre-treatment process for most of the materials, like paper, plastic. UV ink offers optimal adhesion without pre-coating to save time. A UV printer can handle glass, but pre-coating or jetting primer by print head is needed for a permanent bond .
Print multiple colors at one time, the media is kept on the vacuum table stationary and the printing gantry, on which the print carriage mounted move over the media. This allows for multiple layers of printing
simultaneously including white ink , spot varnish or jetting primer.
Compared with solvent or water printing, UV printing provides better color saturation on solid and substrates. It is available to print vivid colors on dark or transparent materials directly.
In conclusion, UV inkjet printer is almost a creative art form from all on its own. The possibilities are endless and only limiated by creativity
Difference from the flatbed printers filled with aqueous ink
There are many a small flatbed printers in the market which use aqueous ink, they are called "all-purpose printers" by the suppliers. In fact, it is an exaggerated view. First of all,the aqueous ink requires pre-treament process before printing on many kinds of rigid materials for good adhesion. Also it is a must to install additional heating facility to make the ink dry whithin a short period to avoid ink spread. This kind of heater unit must be installed under the vacuum table which ensure the rigid media can be heated easily. As a result, the overheat makes the flatness of the table a little worse , which affacts the printing quality too. Recently, more and more printing shops begin to get small size UV Flatbed printers to replace the ones with aqueous ink for the printing business of rigital media.
How to print on flat glass by UV Flatbed printers?
Flat glass or clear glass is one of the most difficult materials for uv printers to print onto directly because the surface is too smooth that the uv ink can't stand firmly. It is a must to do pre-treatment on the glass surface before printing. The traditional way is to use a sprayer gun manually or automatic coater to cover primer liquid on the whole printing area and let the primer layer dry naturally, and then print images onto for good adhesion.
The disadvantages of spraying the primer by separate processes above are waste of primer at the area of no images and easy to be messed up by dust. MPAD UV Flatbed Glass printers are equipped with jetting primer option to print primer and uv ink at one time to save cost of primer,improve production capability and achieve clean prints. It is really the ideal for glass printing business. Moreover, we are able to provide accessory equipments to make the printed products which can be used under strict environment.
If you are looking for the permanent solutions for building glass, then the glass printer filled with real ceramic ink is the superior match for your need.
Why just small format Epson UV flatbed printer with LED curing system
More and more suppliers are working on wide format Epson UV Flatbed printers equipped with LED curing system. Because the drop size of Epson print head is just 4pl, the printing fluency of wide format printing is affected by the quality of the uv inks which are compatible with LED curing system in the market. It is good choice and feasible to make small size uv flatbed printers with epson heads to print small size substrates less than 100cm wide for photographic printing products. Furthermore,the current LED curing system is not mature enough for wide format printing applications as well.
