Binding

Staple binding (saddle stitching)
Essentially an A3 document folded in the middle and stapled to create an A4 booklet. We bind most instrumental sheet music parts this way.
Saddle Stitching may sound like a strange name for a binding process where wire staples are put through sheets of paper, but in the printing industry the collated sheets are often draped over a saddle-like apparatus during the stitching/stapling process, hence the name Saddle Stitching.

Wire binding (wiro)
We use wire binding elements for A4, B4 and A3 scores, some bigger orchestral parts e.g. complete opera parts, and sheet music in landscape format (e.g. some organ music and piano music).
Music scores that are bound with wire binding elements allow the music to lie flat on the stand. 
For B4 and A3 music scores, we use heavy duty 600gsm card for the back cover, and as well as a card front cover, clear PVC (laminate) dust covers are also added front and back as standard.
