As I identified in my research, spot uv can be used to add interest to a design with a contrasting finish to key element(s) of design. I looked at Joe Wicks’ lean in 15 in my earlier research, and he used the same technique to highlight his name and the title of the book.
Spot UV is actually a varnish applied to part of all of the paper stock to give extra “oomph”. The paper is then cured with a UV light hence the name Spot UV.
I looked at various online tutorials to understand how to set up a document implementing Spot UV, however this was the most educational and useful:
To instruct the printer where to apply the effect, the specific artwork should be exported as a separate file in the position it will appear in relation to the paper.
