After I signed off this forum, I went to DPR and asked my question on the Printers and Printing Forum. The first reply was simple and accurate:
Your image is being enlarged and that is why your sample with the 1/8" border is not printing correctly. With Canon printers, and some newer Epson printers, this overspray can be adjusted, as I found out later. Correct me if I am wrong, but I did not see that information in any of Fred's comments prior to me getting frustrated. So yes, I did find out more at another forum. I found out exactly what the "problem" was.
Alan,
I'll get help from other forums.
I doubt it, Fred is a real expert in the use of QU and the program developer keeps an eye on things and posts regularly.
We often have to wade through problems where there is insufficient detail, questions about set-up are not answered, wrong terminology used and misconceptions on how QU works.
Going back to your original post:
I can see a little extra white space on the right and bottom
This is on the page preview on the main screen and it does not matter - it is merely a "preview".
Fred has told you that the accurate position of an image on a page is shown in the Page Editor Size/Location tab.
He's also told you you were wasting time and using Template Centred inappropriately, I hope you've got that now.
In your last post you said:
Below is the image I have been attempting to print as a test. 90% of the black border does not appear on the final print.
You need to understand how borderless printing works, the driver expands the image and coverage of the nozzles to OVERLAP the page size so no white edges are seen at all.
You can see in your driver screen shot a slider showing the level of expansion set to Max - you are bound to loose some of the image at this setting.
QU has a setting to eliminate the expansion completely:
Edit-Preferences-Print and Page Formatting-Borderless Overspray/Expansion. See screen shot below.
A health warning comes with this setting that Fred has already mentioned too: unless your printer feed and guides are perfect, you are likely to set white slivers at some of print edges.
One final point to check since the subject of this thread is "Margin Shifting".
Check that additional page margins have not been set in QU in the Edit-Preferences-Print and Page Formatting again.
See screen shot below which shows almost zero margins when borderless is set in the driver. I don't know why the driver is showing this tiny "fixed" amount on 2 sides, maybe it's a feature of my R2000.
