Gutters, Outer Margins, Spine Width and bleed for the Fold Catalogue.
GUTTERs and OUTER MARGINs
These are set up to add the LIP & HEADS for a stitched signature or fold-lay; and for the GRIND & HEADS on the Perfect Bound Book.
The example below is a 16p signature (fold lay) with bleed, head trim and lip.
The horizontal gutter corresponds to the total amount of LIP you want (where the grippers on a trim and stitch machine will grab the paper and pull it onto the stitching line.
The vertical gutter corresponds to the amount of HEAD TRIM you want (the area between the heads of the book, where you might want notches to alleviate crows feet or wrinkling). Again, You can enter this as a fixed amount or you can enter .5inch and have it doubled by entering a quantity of two. IQ will display all of this on one side of the sheet in the diagram.
If you are wanting to add additional paper to the top (head) so you can put a perf wheel in to take out blousing you can add it to a vertical spine or just add it to the head trim.
When bleed is added to (either at the site level, the press level, or the override), it adds to the outsides of the form, not between individual pages. If you need to account for extra bleed, over and above the form, add it to the outer margins. For example on a 16p form, bleed is required on every side of each 2 page spread. IQ adds it to the form, so you need to make an additional allowance for the bleed between the two 2-page forms. If you wanted .124 (3mm) page, you could add .25 (6mm) to the outer margin.
IF you have a standard bleed set across the board, you need to back it out of the outer margins and (but not the gutters).
