Custom spot UV is a finishing technique used to apply a glossy, raised coating to selected areas of a packaging design. This contrast between matte and shine helps draw attention to key elements such as logos, icons, or text without covering the entire surface. Spot UV can be customized in placement and intensity to enhance visual depth while keeping the design clean and modern. It works especially well on dark or matte backgrounds, creating a striking yet controlled effect. When used with precision, spot UV adds emphasis and texture, making packaging feel more interactive and visually engaging.
