Brad,
I used the selection, "GUIDE LINES" in the Edges selection menu.

Glad that all is working fine for you but I have a question, and I don't mean to pry or to judge, so if you choose to ignore the question I quite understand.

When you use templates in this fashion and the prints will vary in size since the print crop is off and the images are at different aspect, and the templates don't print anyway, the results seem to be odd looking.
By odd looking I have all cut prints at the same size pages as if the prints were on sheet paper, but the smaller prints seem to have a large border that just "feels" odd.
I actually tried to do what you did but I used 4 x 5 templates on 8.5 x 11 paper instead of the 8 x 12 templates.

So what I did was to change the background color of the page to a 238, 238, 238; and made another print.
Now my odd size print looks more intentional than accidental with a faint gray background.

Sorry to butt in, but it must be in my genes..   and you can just detour around the query.

These particular jobs serve three different purposes. In one case, the artist wants consistent sheet sizes because they are inserting them into a portfolio book. A light gray page colour would probably be OK but the extra white border doesn't seem odd as you're flipping through a portfolio book.

In another case, the artist wants to sell prints on a consistent sheet size. The border should be white all around so the buyer can trim and matte them as they see fit, e.g. use a standard pre-cut matte (and have extra border) or custom cut a matte to fit the image. A gray page colour would hamper that.

The third case is to provide canvas proof prints when I scan a number of paintings for an artist. Here again I want the sheet sizes to be consistent to reduce trimming complexity and time (even at the expense of some  wastage). I think the background should be white all around so the image colours aren't contrasted with the page colour.

Cheers!

Brad

How about adding a 12" x 1" white tif at the top of the template?

I suppose you're right. I've come to know that QU has huge amounts of built-in capability, perhaps largely untapped by most users. If QU has been programmed to do what I need, I think that's worth finding out.
 

Clever ideas. I will certainly try them out.

Thanks Ray (and Brian).
