Digital BW, The Print

You may find this method as helpful as I have for creating several 
test strips on a single sheet - you can compare Paul's Curves, USM 
settings, Layer effects or anything else on the same piece of image, 
alongside one another. 

My setup is PS 6, an 1160 with Epson driver & Paul's curves,  but I'm 
sure it's easily adaptable to Piezography or other systems. Thanks to 
Antonis for helping me get here.

To print  horizontal 8x2" strips (the printer is faster if the 
selection is in the same direction as the head moves) 5 times down 
a "portrait" oriented sheet.

On an 8.5x11 sheet :

1. on the image to test print, use the rectangular marquee to select 
a fixed size, say 2 inch x 8 inches (file must have been converted 
from 16 to 8 bit & be in RGB mode, make a duplicate if necessary).

2. Save the selection to an Alpha  Channel (which can be reloaded).

3. Load the Selection  > apply the Curve, or USM, or any other effect 
to test

4. in Print Options, for the 1st test strip - Position > set the Top
position to .25 & the Left position to .25 (to leave a little white 
border),
and Page Setup> Properties> Main & Paper > select your usual 
preferences.

5. Print> Print Range > choose Selection (if Selection option is 
grayed out, go back to image and make sure selection is loaded/active.

6. for the 2nd test strip, set the Top position to 2.25 inches

7. for the 3rd ,set it to 4.25 inches and so on, adding the width of 
the strip (2") each time for the 4th, 5th  - 5 8x2 strips fit 
comfortably.
