Preparing an Imposed Job
Let's prepare an imposed booklet using the unique imposition features of the Spire Color Server.
We will use the document you are reading now (Letter size), and impose every pair of pages on
each side of the printed sheet (Tabloid size).
Note that since Tabloid is exactly twice the size of Letter, we have no space for additional margins
(that can hold the crop marks) or gutters (the space between the pages). Therefore, in order to
demonstrate the complete functionality, we will reduce the Letter size document margins.
A further exercise can be to use a larger paper size than Tabloid (such as 12"X18" paper).
This will enable imposition of a full size Letter, including the required marks and margins.
