Hi just to continue where we left off from our last post, i would like to talk about the other print finishing options available:
Folding is something that takes place after the job has been printed and guillotined. The sheet is then folded to the finished size very common for leaflets and menus. There is lots of folding options available to the client.
1) Single fold – This is where the sheet is folded down the middle to create a four page product
2) Roll Fold or Z Fold – this is where the sheet is folded twice to create six pages very common for menus and leaflets
3) Gate Fold – this is where both the edges of the sheet are folded in to meet in the middle, this is generally for longer products or square finished products
Creasing is something which is done to the sheet if the sheet is thicker than 200gsm to aid with folding. Once creased then the sheet is folded. If thick paper is folded without creasing this would result in the sheet splitting or cracking and the result would be a printed product that is awful in terms of quality and finish. Creasing is carried out by a creasing blade which creates a compression to the sheet and this then enables you to fold the sheet without it cracking.
Collating is where the printed sheets are gathered and arranged into a sequence which creates consistent logical sets. This process is carried out to books, booklets and Ncr sets. All books and booklets are collated in numerical order before being stapled or bound. Ncr sets are collated in the correct sequence required by the customer.
Perforatin is basically very small holes in the sheet of paper, these are to allow the sheet to be separated/torn easily. This can be done to leaflets where there is a voucher to tear off or Ncr books where one copy is torn from the book to give to the customer. This is also very common on tickets where the stub is torn off.
Thanks again for reading more to come soon 🙂
