    Okay, ignoring the whole Japanese vs French fold thing, the way to set this up is to re-jig your document so that the right hand page of every spread is on the left hand side with the next spread's left hand side next to it on the right. If you're not sure, make a small blank french-folded mock up if the amount of pages you are planning, then pencil in on each page "Front Cover" "Inside Front Cover" "Page 01" "02" etc etc... then tale the blank mock-up apart and sprad the sheets out and use it as a guide to where things need to be positioned.

    If you are perfect binding (For French Fold) you need a minimal pinch of 4mm or so. Also is you are French-folding correctly you will be self-covering (ie the cover is the same stock dealt with in the same way as the text pages) If you are Japanese binding you need a pinch of at least 10mm but possibly more depending on your page size and the skill with which you intend to stitch. You will also need to provide a single plate of a total coverage repeat pattern print as spread to view for the insides of each leaf to prevent legibility issues caused by show through.

    There really fundamental considerations to make between French and Japanese and I suggest you discuss with your actual needs with your printer before setting he document up, rather than just saying "its French fold".

    • You need to leave a small gutter for the outside edge fold determined by the thickness of stock...Horp
    • Measure the thickness of 100 sheets of the chosen stock, divide by 100 for sheet thickness, mulitply by 3 for...Horp
    • minimum gutter.Horp

    Also, as proper french fold is done on thicker stock than Japanese you need to check the grain of the chosen stock is running complimentary to the fold when planned on a sheet. If you try to get your spreads out of a sheet across the grain you will get a brittle feeling piece with broken outer edges and a twist/warp to the book. Grain must run vertically to print to ensure a good finish. This usually means running a spread across a sheet width not its length, which can mean that an A4 finished document needs to be planned 2up on an SRA2 sheet not an SRA3.

    Horp, you sir is what I would call a messiah. You have successfully made it to number 1 on my payback board. Your time will come.

    Excellent post.
