UV curing eliminates tracking of ink. With UV curing, the product can be converted in line. Fold, bind and ship product same day. The press operator can increase speed of press. Instant drying allows press speed to be doubled. UV inks can be formulated to be heat resistant. The printer can run products and forms for thermal printers. UV gloss coatings or UV Protective coatings can be applied in-line on Location: Mission Street Carol Stream, IL USA. Curing of Printing Inks by UV Technical Paper By Jim Raymont T he use of ultraviolet (UV) energy is what differentiates UV-cured inks from water or solvent-based inks. While a UV ink is “dry” to the touch after it has been properly exposed to UV, the actual “drying” mechanism is one of polymerization and not the evaporation of water or a. cure UV LED inks is very narrow, – nm, as compared to a UV mercury system which operates from – nm range. UV LED Curing Because of the limited spectral wavelength, UV LED primarily operates in the UV-A zone and considered to be ‘safe’ because it is closest to visible light. However, prolonged exposure to. Radiation curing is the fastest growing technology in the inks and coatings industries. The popularity of this technology was the drive to publish a book like this. It has been written as reference guide who combines theory and practice for the daily work.
Sep 11, · Ultraviolet (UV) rays are a type of electromagnetic rays used to initiate the photochemical process, or UV curing, in inks, varnishes and coatings. UV inks are made up of oligomers, monomers, pigments, additives and photoinitiators. The polymerisation reaction can be via a radical or cationic mechanism. There is to 2 times more pigment in UV inks than in solvent and water-based inks. Epoxy acr ylates are extensivel y used in UV curing in litho inks and varnishes, roller coating varnishes for pape r and board, printed circuit boar d, wood and plastic coatings. PRIME UV-IR Curing & IR Drying systems are easily installed on both new presses and as retrofits on existing presses and machinery. PRIME UV Curing Equipment instantly cures UV Inks, Coatings & Adhesives. Our Curing Equipment is Recommended by the EPA as BACT (Best Available Control Technology) and meets Clean Air Requirements. Finally, the cost of UV chemistry on a coverage basis is less expensive than with solvent- or water-based inks and coatings, and the UV curing process consumes less electrical energy than that of hot air of IR ovens to effect drying. Please see the papers "Why Use UV," and "Quality Improvements Through the UV Curing Process" in the Tech Sheets.
The UV-curable ink is cured and adhered to the media or substrate by UV radiation. The print is already dried when it comes out of the printer, allowing a short delivery request to be met. Printing on non-absorbent materials, including plastic, glass, and metal, is happyplacekidsgym.comon: Shigeno-Otsu, Tomi-city, Nagano, Japan. Safety Tips for Using UV Curing Systems. What Are UV Curing Systems? UV curing is a speed curing process in which high-intensity ultraviolet (UV) light is used to create a photochemical reaction that instantly cures inks, adhesives, and coatings. Curing systems are widely used in optical, fiber-optic, electronic, laser, microelectronic, and. Light Sources > Uncategorized > UV Ink Curing The process of UV curing has been around since the ’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. The primary advantage of curing finishes and inks with ultraviolet light is the speed at which the final product can be readied for shipping. In addition to speeding up production, this can also reduce flaws and errors as the amount of time that dust, flies or any airborne object .
