Fiery Impose offers two different Scale to Fit behaviors with gutters.

Scale to Fit is needed when the original page does not fit entirely within the available imposition slot on the sheet. The imposition slot size is defined by the sheet size and the number of imposition slots on the page (a function of the numbers of rows and columns). The gutter setting defines the space between the imposition slots.

If you have selected Scale to Fit, the Gutter dialog box offers a "Scale to fit" uses gutter settings check box. The behavior of the check box is as follows:

• Not selecting the check box (default setting) - Scale to Fit does not include the gutter size in the calculation. Changing the gutter size does not scale the page content, and instead shifts the content. 
• Selecting the check box - Scale to Fit includes the gutter size in the calculation. Changing the gutter size scales the page content to fit within the area defined by the rows and columns and gutter settings.

If the user selected Scale to Fit, changing the gutter size automatically changed the scaling. The document was resized so it continued to fit in the available area. Note the following:  The user selected Scale to Fit option so the page always fitted within the available imposition slot, no matter the gutter size or sheet size. Changing rows and columns or sheet size affected the scaled size. Changing gutter size affected the scaled size. Scale to Fit scaled down, not up.
