Hi all
I'm just wondering if you can help please. I am printing some large images onto photo paper (around 45" x 30").
Some of the images are not the best in terms of quality (pixel dimensions).
I'm just wondering what the process should be and am wondering if anyone could give me some advice. I need to make the printed images all the same size and this means cropping some of them.
If I set up a custom size in Qimage and leave that to do the crop, I cannot determine where the image is cropped as far as I can see. I need to be quite precise with my crop position.
What I have done is created a spreadsheet to calculate the required height/width in pixels. For example if I have an image that is 2800px x 1800px and I want to crop it to make it the same proportions as a 46"x35" print size I would plan to keep the 1800px and reduce the longer side to 2366px.
I know in terms of PPI this is low for printing (51ppi at 46"x35").
What I'm wondering is re: the actual resizing.
I have OnOne Perfect Resize and am wondering if I should do the cropping in there (not making it bigger, just cropping it). However, I am wondering what the better process would be - should I:
a) resize it in Perfect Resize and change the PPI in there to something that multiplies into 600 for the HP resolution (75, 150, 300 etc)- just the small crop to get the proportions right, not taking it up to full print size - I would use 75ppi for this example which is actually 51ppi so it is not taking it up by much
b) just load it straight into Qimage at 2366px x 1800px and let it take care of the interpolation etc
I am using a HP printer (native ppi = 600). Qimage will recognise this automatically and do it's stuff. if I use Perfect Resize it offers me the option to select whatever PPI I choose. My thinking was to choose 75ppi or 150ppi as this multiplies up into the native 600. Does it work like that? I have read about using 150ppi but not 75ppi - would it multiply it up just the same?
I hope that makes some sense
If anyone can share their thoughts that would be great. I plan to do some testing myself to see how the different settings affect the prints but just to know I am thinking in the right way (ish!!!) would be good to know.
Many thanks!
Phil
