Shunxingyuan Packaging, a professional flexible packaging manufacturer, believes that in the flexible packaging industry, spot UV printing is widely used. Packaging bags for industries such as apparel, clothing, cosmetics, hardware, electronics, and food all utilize UV printing. Spot UV refers to the localized application of a gloss coating to prominent areas of trademarks and packaging prints, according to the product's glossing needs. The glossed pattern appears more vibrant, bright, and three-dimensional compared to the surrounding patterns, creating a unique artistic effect.
Spot UV varnishing is a type of surface finishing technology for printed materials. It gets its name from the selective varnishing of printed graphics and text using UV varnish with high brightness, transparency, and abrasion resistance.
While highlighting the page theme, it also enhances the decorative effect of the printed surface. Spot UV is primarily used in post-press finishing of packaging products to achieve the goal of adding "the finishing touch" to printed materials.
Differences between full-page UV and spot UV effects:
1 、Full-page UV
The effect of full-page UV is not very obvious; superficially, it resembles over-varnishing and appears brighter than over-varnishing, but it does not provide protection to the printed surface. Over-varnishing offers some protection to the printed surface, such as preventing scratches.
2 、Spot UV
The true essence of the UV process is reflected in spot UV. For example, for brochure covers and color boxes, spot UV is often used to highlight key text, company logos, product images, and other areas. Text and images treated with UV have a more textured, three-dimensional, and artistic feel.
