Introduction
UV Printing or ultraviolet print is a new and popular technique of printing, used to achieve high quality and much more durable prints on a number of different materials. In this tutorial for novices, we’ll discuss how UV Printing differs from other methods and why its popularity is quickly rising among commercial printers and product makers.
How UV Printing Works
UV printers don’t employ liquid inks like most inkjet or laser printers but utilize a special UV-curable ink which solidifies and dries up through thermal curing caused by UV radiation. Here is a breakdown of the UV printing process:
1. UV Ink Application
UV printing employs an ink that has photoinitiators – particles which respond to ultraviolet light. These ones are taken to the printing surface in forms of liquid just like traditional inks.
2. UV Light Exposure
The moment the ink.is applied, a high-intensity UV light is shone directly onto the print surface. The UV radiation here causes the photoinitiators in the ink to solidify through cross-linking to form a solid polymer network.
3. Instant Curing
It uses high intensity UV light that can dry up the ink within seconds from a liquid state to a solid state. Because of this instant curing, UV prints can be handled calmly and finished right from the printing equipment without necessarily allowing for extended time for the prints to dry.
4. Additional Print Finishing
Any other finishing processes such as lamination, or varnish or mounting can be done right after printing without dampening the image or affecting print documents through moisture. Fundamentally, this simplifies the flow of work as opposed to other printing techniques, making workflow much faster.
The utility of the UV Printing Technology is summarized below
UV printing offers several benefits which increase print quality and extend the range of services compared to previous technologies such as inkjet, laser printing, and offset printing. Here are some of the main benefits:
- Drastically shortened dry times coupled with other print finishing processes because of quick UV curing
- Better wear and tear and more resilient due to the fact that UV inks cure on the surface chemically
- Bright and sharp image that would not smudge the wet ink or have a loss of detail.
- Wide compatibility of the machine where it can accept both rigid and flexible print material.
- Flexibility in that the company can print on some sensitive products and materials which are highly sensitive to heat.
- Low emissions of VOC and less waste is produced
- Economical for small volume, and more often printing needs.
UV Printing Applications
The advantages of UV printing make it a preferred choice for a variety of consumer and commercial printing applications, including:
- Product Prototyping – Suitable for effectively modeling products specifically during the designing process.
- Packaging Proofs – It is a product that enables packaging print to be done without having to conduct a complete production.
- Labels and Stickers – Delivers long-lasting and colourful sticker and labels
- Signs and Displays – Perfect for multi-brand retail signs, window advertisement, point-of-purchase Notice: The signs and display generate good sales to the target market.
- Advertising Specialties –Sales previews for imprinting on to pens, mugs, electronics goods, trophies, etc.
- Plastic Embellishment – This involves the beautifying of plastics which can be in phones covers etc.
- Direct-to-Shape Printing – Print directly onto curved and complex concave and convex shapes.
- Genuine Leather Products- Sells stylish and fashionable car accessories such as leathers belts, wallets and bags
UV printing provides better quality while opening up the print potential in ways that traditional forms of printing cannot measure up to. With the progressive development of new type of technologies, the UV printing technology is expected to increasingly edge out the conventional technologies for many uses given its adaptability, effectiveness and superior performance results. It also creates its environmental benefits that further support its use as a solution with the constantly shifting consumer and industrial standards. To both incumbent printer converters and entrants, the knowledge of UV technology forms equally immense novel pools in the outlook visual communication markets.
