Imposition

Imposition shows the designer and printer how the various pages of a publication are to be arranged for print. It consists in the arrangement of the printed products pages on the printers sheet, it allows faster printing and simplified binding. It also maximises the number of pages per impression which in turn reduces the press time and paper waste.

Considerations
- Format
- Paper fibre direction - must reflect the grain of the paper with the alignment of folds.
- Number of pages
- Stitching / binding method
- Finishing / Binding

A few examples of Imposition

Throw Outs
A throw out is a half gatefold that in the same way as a gatefold on one side only, again the outward folding panel is slightly smaller so that it fits neatly when folded. (Left Vector)

Gatefolds

A folded sheet of four panels that is bound into a publication so the fold into the spine with parallel folds. The middle panels are the same size as the rest of the publication but the outer two panels are slightly smaller to sit neatly while folded. (Right Vector)

>>>>Tip Ins and Tip Ons
Extra elements can be added to designs to give them that special feel, tip ins and ons are when a page of different stock or a different size is added to the publication.

Tip Ins
A tip in is an added single, page often in a different stock, or size. They are done by wrapping it around the central section of a publication and glueing along the bind. It has to be alligned to either the bottom or top of the bind. To the left are a few examples of how the different elements could be added. Cyan represents the original publication size and Magenta the tip in.

Tip Ons
Tip ons are when an element are pasted into publications anywhere on the host page.  They can be permanent or temporary. Often used for attaching credit cards.
