Spot UV
Spot UV is a commonly-used effect on Book and Magazine covers. You can apply it to specific areas of your design to create a noticeably shiny, contrasting surface. Spot UV is different to lamination, which we use to cover the entire book surface to protect it instead of adding a visual effect.
We apply the UV coating over your artwork, which creates semi-translucent areas. Please refer to our Spot UV set-up guide to see how to add this to your print design.

Metallic Foil
A foil imitates metals like copper, silver or gold. So when light hits the foil, it has a shimmering effect, bringing a sense of luxury to your finished print job. If you would like to add a foil to your next print job, our foil setup guide will show you how to do this.

Variant and Sketch Covers
Make your Comic Books and Graphic Novels even more desirable with a variant or sketch cover.
Variant covers feature exclusive artwork or specialty finishes - while sketch covers are custom front pages that we print on uncoated paper so artists can add custom art to the cover once printed. Check out our set-up guide to find how to incorporate these into your next print run.

Endpapers
Endpapers, endsheets, or endleaves are double sheets of paper partly glued to the inside of a book's front and back cover. Made from a slightly heavier paper stock than inner pages, they serve as a protective barrier dividing the inner text from the cover. They can also serve as a decorative feature.
Choose from a range of colours from the dropdown menu on our Instant Quote Calculator and refer to our Endpapers Support Page for more information.
