Blue Back Finish

It’s exactly what it says. Blue back finish is a poster printing material which is usually white on the front finished with matte, gloss or satin coating with blue coating on the back.

The blue coating is designed to block any type of light shining through.

It’s especially useful if you’re planning to stick your poster up on your window.

Blue back coating is normally used in bill boards as they’re very useful in blocking harsh sunlight shining through it and disrupting the content on the front.

The wide range of budget posters are usually 170gsm and they’re too thin to block any light coming from behind. Tis does not matter if you’re planning to stick your poster on a blank wall or on a frame.

Advantages of Blue Back finish: 

Blue Back material is a type of poster printing paper which is typically white on the front and blue on the back.
