Test print crop reduces image

« on: December 10, 2016, 04:35:43 AM »

Sorry about the redundancy, I just realized there is a separate Qimage Ultimate subforum, I mistakenly posted this identical post in the regular Qimage forum location. I am re-posting here as Ultimate is the version I have.

I've been using Qimage Ultimate for a while now, i just upgraded to 2017.110. I've read the different posts on how to do test strips but it seems to not work correctly for me. My problem is that the "test strip button" when activated says "test strip crop and reduce"...or something to that effect. And that is exactly what it does, it reduces the image from my original intended size. Lets say I'm doing a test strip on a 8.5 inch by 11" paper, I specify a print size of 8x10, I go to "edit page", I wish to take a test strip out of this 8x10, when i activate the test strip button that 8x10 image is automatically reduced in size!!!! Thus i cannot get a true crop of the image as if i printed it at 8x10. How I'm trying to use it is to take a crop from a much larger print, then print it at a smaller paper size. I understand how to do that, but Qimage does not hold my specified print size when i activate the test print crop button as it reduces that size. Is this normal?
I'm using Windows7 with Epson P600 printer.

Hi Danall,
The test strip feature is designed to make a smaller print of a section of the full size print at the same print ppi. You could start with an 8x10 print and make a text strip on, say 4x6. This could be printed on some 4x6 paper or on larger paper if you want to make several test strip prints (one at a time).
In your case, set up your 8x10 print and if you then hover your mouse over the preview it will tell you the print ppi, say 400ppi.
When you click the Test Strip icon, the print size is reduced and the image cropped but the print ppi will remain at 400ppi.
If you now change the print size to say, 4x6, you will see the print ppi will remain at 400ppi and in the page editor it's possible to move the crop position to a critical part of the image.
Either print on some 4x6 paper or on your 8.5x11paper, positioned so more test strips could be printed alongside.
See attached scree shots:
-004 shows the full size print in the queue at 420PPI
-003 shows the page editor with a much smaller print size but the ppi remains at 420ppi

Metric conversion 140x100mm = approx 5.5x4" and 280x200mm = approx 11x8"

Hi Dan?
The object of Test strip is to allow you to select a section or area of an image and see exactly how it will look at the exact same ppi as the final print.
Suppose you have a great shot of a bride in a wedding dress. But will the fine detail in the white embroidery show clearly?
You intend to make a 16 24 print. Based on the resolution of the image, you see in your preview screen main screen, 190 ppi. (Plenty of ppi for a fine print.)
To be sure the detail in that dress will be as finely detailed as you wanted, you use test Strip.
By clicking the test strip repeatedly you are zooming in on an area.... and by dragging the image in the small box upper right, you can zero in on the part of the dress you want to see.
Above that box is the print size that can be made for you to use a small sheet of paper, and to maintain the 190 ppi.
That is the operative phrase. Maintain the actual ppi that will be used in the 16 x 24 print.

You select the size that will enable you to see and to print on a small piece of paper.
Again, the object is to see a portion of the image on a print at teh actual ppi of the large print.
094, the image... Will I be able to make out detail where those signs are? See red box of te area of interest.
095 Small box with hand icon to drag
096 The area I want to test print at the same ppi as the final will be.

In the last screen shot, 097, I want to see if there's enough detail in a 16 x 24 print of the center of this flower.
It says I can peek at it by making a print 5.14 x 3.36 inches at the same ppi.
So I take a piece of 4 x 6 and make my test print before I waste a hunk of 17 x24.

thanks a lot for responding, I see what you mean, i tried a test strip and monitored the PPI as you indicated, I was thrown by the automatic image reduction and associated crop. I understand it now.
