Since I'm using roll canvas on my Epson7900, Is there any way to do mutiple edits (or interpolations of the same image), in a row of lets say 3 or 4 test "strips"
David,
To the best of my knowledge, the interpolator (Fusion, Hybrid, Pyramid) isn't a factor until you go to print to paper, print to File, ot upsize or downsize an image
You aren't seeing an interpolated image in Full Page Editor; but a High Def image or a low rez image, depending on your selection.
The test strips can be adjusted to aspect ratio of your choice by selecting the print size. You can click on the Test Strip icon and set to the magnification you want, and change the print size (aspect ratio) with a Right click on the image, and select a new size.
You want strips, make a custom print size (Auto crop on). It can do just about anything you want.
This feature is designed to show you on a small sample print what a section of your image will look like; is it sharp enough, wedding dress too light or too dark in print.
You can use 4 x 6 paper or cut some off your roll, and make 3 test prints using 3 interpolators.
That's the way I might do it.

PS I forgot to mention that the object is to keep the same ppi in the 4 x 6 test print as the large finished print will use.
