What are some high quality devices for printing custom labels?
If you want stickers that last, you've got to print them on weatherproof vinyl, and if you want what you print to last on your sticker, you've got to cure your inks properly. When started out in 1993, we hung our stickers to dry. That worked okay, but now we use UV-cured inks, which are completely scratch-proof and fade-proof. When applied properly to a clean, dry, smooth surface, our stickers are there to stay.

They are polymers often used with inks and also tooth repair. The monomers chosen are those that will polymerize on exposure to UV light radiation. In the case of an ink, after it is applied it is usually passed under a UV light to cure it. Similarly, after the tooth is filled, UV light is applied to harden it.

Are UV tattoos really dangerous?
Hmmmmn, why are they uv activated???? Because they have an iridescent factor.. Most things that have an iridescent factor are known carcinogens....That means a cancer producing agent....Let's take a cancer producing agent and pound it into an open wound!!!!!!! I dont think so...Besides if you want the ink that you can only see when it's under a black light, that will only last 6 months before it fades away.....But dont worry the cancer may hang in there forever.....Remember Kids!!! There is no federal agency that checks out tattoo inks...When a new line of ink comes out, there are no inspections or tests....They will re-call it if enough people complain......Be carefull!!!!! Hope this helps
Ink making in commercial printing?
There are various types of inks used in commercial printing. Currently the most popular inks are soy based and ultra violet. Soy based inks work best with heat-set presses, which use an actual flame dryer to set the ink. While UV presses use ultra violet lamps to set the ink. Both types of presses, and sometimes ink too, can be found online at http://www.printersmarketplace.com

What is the difference between shellac and lacquer nail polishes?
shellac nail polish is half gel and half polish, and its cured by UV light and dries IMMEDIATELY after the manicure process. the UV light sorta makes the shellac nail paint go plasticy, which makes it lasts longer. its thin, but super glossy and lasts up to 2 weeks. i'm not sure what lacquer nail polish is made out of, but i know that it dries super quick (without UV light) and can be applied in one quick flick. it's also super glossy. so maybe the difference is that shellac nail polish is half gel and it's cured by UV light? idk. hope i helped:)

Which printer or printers will print banners?
I'm assuming you mean outdoor durable vinyl printed banners such as the ones we offer at www.gobigbanners.com. If this is the case, then these are printed on a wide-format solvent ink or UV based ink printer. There are many different manufacturers of these printers out there, some of the big players in the arena are Roland, Epson, Hewlett Packard, Mimaki and Mutoh just to name a few. The key feature to a printer that you intend to create outdoor durable banners with is that the ink be either solvent based or UV cured. Solvent based inks have a volatile compound that enables the ink to be absorbed by the vinyl print material, essentially 'fixing' it into the vinyl. These ink can be low VOC (Volatile Organic Compound) which does not require ventilation for safety, and high VOC which would require an extraction system and would smell strongly while they are 'gassing out' or curing. UV (Ultra-Violet) inks do not have any VOC's and do not require heat to cure. Instead they have concentrated UV lights that cause a chemical reaction between the ink and substrate (the banner material) essentially turning the inks into a solid that is bonded to the substrate. These are even more durable than Solvent based inks. While it is possible to print outdoor banners on a water-based wide format printer, it would be necessary to then coat the banner in some kind of a laminate to prevent weather from rapidly degrading the print and washing the ink off. Hope that helps you, Eyezac
