Paper over board is environmentally friendly and cost effective. From your full colour litho printed sheets we mount and line onto board. We can give you full specifications and provide lay sheets for you to arrange the design, printing and lamination of the paper. Any size of binder is possible, because our traditional binding methods usually require no special tooling.
THE TECHNICAL STUFF
Paper over board binders can be made in any size you wish, but most follow the same basic sizing rules. To determine the size of the front cover and spine, it is necessary to know the size of the largest sheets to be accommodated, and the total thickness of the contents.
The width of the front cover and the spine of the binder need to be large enough to accept the ring mechanism. The spine measurement is not the same as the ring capacity.
The outer covering paper needs to be 40mm bigger than the board case, to wrap around the case with a 20mm turn-in on all 4 sides.
The lining paper typically is 10mm smaller than the board case, to leave a 5mm border all round. If the outer covering print is to be a solid colour, the print should bleed beyond the turn-in area, so as to not show white paper on the inside of the finished case.
Matt lamination onto large areas of dark print is not advisable as it is liable to show scuff marks easily.
The The following table gives the suggested dimensions for a one piece case 'D' ring binder to accommodate an A4 portrait sheet, with allowance for a 15mm tab. (This is sufficient to also house a normal A4 polypocket).

The spine measurements given above are measured centre to centre of the creases. When designing the outer print, don't forget the position of the rivet heads used to fit the ring metal. (For a 'D' ring mechanism the rivets are positioned on the back cover). For special sizes we will assist you in sizing and can advise of lay-downs.
