Probably a dumb question, but I don't understand what Print Tool will do if I put multiple images on a page with different resolutions. Say I have one image sized to 480 and another at 360PPI, will Print Tool work it out, or will I get one or both the wrong size?

Thinking about resizing a little more, Jon Cone advised me to set DPI in the image and let QTR sort it out. I have been using PK Sharpener to set the DPI by telling it the print size. This gives me odd numbers like 463DPI. Can QTR use any number or does it resize to one of the multiples like 360, 480 or whatever?

If you have a really low resolution image (less than 200-240 maybe) you may want to upsampleusing Photoshop or some special technique so you can sharpen or whatever afterward.But as long as you have decent resolution I'd just pass the image in as is -- 463ppi would be just fine.On the way to dithering QTR driver will be up sampling to 720ppi regardless of what you send.Roy

HiReading your answer, since I have plenty of resolution in my originals, should I save my pictures (out of Photoshop) at 720 dpi for a maximum sharpness?Thanks

You really have got to try stuff like this. Anything that involves "what happens on a print" isup to you/whoever wants to know.Roy

I've been all over the documentation and 720ppi thing isnt mentioned anywhere, but Roy has addressed a few times it here, as well as other forums. But he said it; you gotta see what works for you.Personally, I used to be very picky about downsampling to the 720ppi output resolution, but determined that unless I am printing a huge file at a much smaller size I don't usually bother anymore. I base my scanning resolution based on how big I want to print so I would scan a 120 film to print at 360 at 24x24, and then down sample a copy to 360ppi at 16x16, and use that file to print an 8x8 at 720, Now that I am doing a lot more with digital capture if I have a file that will print between 300ppi and 720ppi I leave it alone and just let the driver do the work. I don't print larger than the file will go on its own without up-sampling so that can of worms is never really an issue...Richard Boutwell

This discussion has been about Print Tool. Does the same 720 thing happen with QTR on Windows?
As Jeff said, there's a comment in Jon Cone's new piezography manual that suggests that QTR uses whatever you give it, which at first glance doesn't seem to quite gel with what Roy said. But perhaps there's more going on in QTR than we realise.
