Deciphering When to Use UV Vellum

Do you know whether you can use UV vellum for artwork images when sandcarving? Find out the answer.

UV vellum is a natural paper pulp print film for laser printers and is ideal for bold artwork and bold text, but it is not recommended for detailed images, such as fine lines or script type fonts. During the exposure process, UV light passes through the UV vellum and exposes the photoresist film. However, UV vellum is not a clear film, and therefore diffuses the light before it exposes the photoresist film. A clearer film, such as laser film, allows the UV light to directly penetrate through the print film, exposing the photoresist film and capturing fine detail in the artwork.

I recommend having a laser film print product on hand for the detailed images; use the UV vellum for bold images only.
