Frequently Asked Questions — Spot UV Printers
What is spot UV printing?
Spot UV printing is a digital or post-press finishing process where a clear liquid ultraviolet-curable polymer (varnish) is applied to specific areas of a printed sheet (rather than coating the entire page). It is instantly cured with UV LED lamps, creating a high-gloss, glossy, or raised contrast effect against matte surfaces.
Can GNFEI UV flatbed printers print 3D raised spot varnish?
Yes. By laying down multiple layers of clear varnish ink or depositing a high-density layer of white ink underneath the varnish, our spot UV printers build a thick, tactile 3D relief (often called sensory or raised embellishment) that adds texture to packaging, labels, or promotional items.
What is the difference between spot UV and full UV coating?
Full UV coating applies a glossy varnish layer across the entire surface of the sheet to protect it. Spot UV applies the gloss varnish exclusively to selected elements (such as logos, graphic assets, or text), creating a matte-gloss contrast that draws the viewer's eye and offers a premium tactile experience.
How do I prepare a spot UV mask design file?
To print spot varnish, create a separate layer or design file (often called a spot mask) containing only solid black elements (100% K). The black shapes represent exactly where the printer's varnish printhead channels will deposit the liquid clear coat, while leaving the rest of the sheet dry and untouched.
Do I need custom plates or screen mesh for digital spot UV?
No. Traditional spot UV printing requires screen printing mesh, custom plates, or hot stamping dies. GNFEI spot UV printers are 100% digital, meaning they jet the varnish directly from printheads based on your software files. This allows for zero setup costs, instant job switching, and zero MOQ print-on-demand services.
