The cross folding sequence is firstly a half fold, parallel to the shortest edge (folded around the back), then a second half fold (also folded around the back) as demonstrated in the diagram below.
The bottom-right quarter panel of the front page is upright; it is the first panel that is seen when folded. The design template shows this panel with a red page edge.
If you have a one-sided cross-folding product, and want the white side to be on the outside when folded, then a ‘Reverse Cross Fold’ will need to be specified using the FRCROSS Finishing code.
Panel 1 appears on page 1 of your document and is upright-reading. All others panels should appear upside down in your design application and Print Ready PDF.
We'd recommend printing out your design to ensure your layout works (we impose left to right).
