Does UV light cure ink?
Does UV light cure ink?
Using UV light instead of heat, the UV curing process instantly deposits a hardened layer of ink onto the substrate. While conventional heat- and air-drying processes entail solvent evaporation, UV curing does not.
How long does UV ink take to cure?
The general rule of thumb is that this post cure period for free radical UV inks lasts for 24 to 48 hours after printing. Inks companies now have published in their tech bulletins that this curing period may last longer than originally thought.
What UV lamp is best for curing resin?
MELODYSUSIE UV Nail Lamp Dryer With a wavelength of 365 nm, this UV lamp is ideal for curing UV resin in addition to many other materials.
What is UV curing lamp?
UV curing uses high intensity ultraviolet lights to create a photochemical reaction to instantly cure adhesives, coatings, inks, varnishes, decorative glazes and lacquers. When the correct intensity of UV light is used, a chemical reaction occurs that produces a byproduct that hardens the resin.
What is UV cured ink?
Ultra violet curing (UV curing) is a green technology that uses a photomechanical process to instantly dry ink after printing. This means that you can print on virtually any type of non absorbing material including glass, wood, metal, vinyl materials, and more.
How do you dry UV ink?
The process of UV ink curing has been around since the 1960’s and uses high intensity ultraviolet light to create a photochemical reaction. By using the proper intensity of UV wavelengths, a byproduct is produced that hardens resin and dries inks.
Why does UV light cure?
UV light can be used to harden particular glues, resins and inks by causing a photochemical reaction inside those substances. This process of hardening is called ‘curing’.
Do you need a special UV light for resin?
UV resin will require a UV lamp or a window with ample sunlight in order to cure, while 2-part resin should be poured in an area where you can cover the pieces to keep them free of dust for a few days.
Why is my UV resin sticky after drying?
Tackiness or stickiness may be noticed on the surface of some ultraviolet (UV) light-curable adhesives and coatings. This phenomenon, known as oxygen inhibition, is the result of atmospheric oxygen inhibiting the cure on the surface layer of the polymerizing material.
How does UV ink dry?
UV ink dries in a chemical polymerisation reaction, initiated by UV radiation. The most common is free radical polymerisation where a photoinitiator molecule cleaves when absorbing UV energy, leaving free radicals in the wet ink film.
Where is UV ink used?
UV ink is designed to be used on a wide range of applications from plastic, glass, metal, and wood to other non-traditional substrates such as garments. UV inkjet ink is available in hard, flexible, or edible ink. Some of our UV inkjet inks can be paired with an ink primer to guarantee longer adhesion.
