When binding a document by folding each sheet, it will cause the contents on the page to shift across depending on where they are in the booklet. Sometimes, it is desirable to adjust for this so pages still line up in the bound copy. This is called “creep”. Quite Imposing has a Creep function. (Originally this was found under the Trim & Shift function, but this is more limited).

The choices are as follows:

• Entire document, or signatures. If you are folding the finished result once to make a complete booklet, use the first option. This will work whatever the page count. If you are going to make multiple folded signatures for binding together as a book, you must choose the second option. The signature size is in pages, not sheets. So a signature size of 32 pages will eventually be 8 pieces of paper printed on both sides.
• Paper thickness or total shift. In most cases you would use the paper thickness and the total shift needed is calculated. In the case of working with signatures you can also give the total shift needed.
• Inside or outside pages shift the most. Consider the case where the first and last pages are a wraparound cover. You would need to leave the outside unshifted, so the middle pages would shift the most. But consider when the middle two pages are designed as a centre spread. In this case you would leave the centre unshifted and shift the outside pages.
• How to make the adjustment. Before 6.0 the adjustment was always to shift the page sideways. This is now an option Scale pages horizontally. When pages are scaled, the scaling is only horizontal, so the shapes change (squares and circle are now slight rectangles and ovals, though this may be undetectable in most real world cases). Scaling may be particularly useful where the page design runs very close to both edges, and shifting would affect the design.
