That's all fine enough, Howard, but you may be sending more ppi to the printer
than
necessary. Whether you will get better results with less is moot, only you can
tell for
sure, but you might experiment just to see if any quality diffs and to speed up
printing
if nothing else.
General rule of thumb is that no inket visibly (at least without a loupe)
benefits from
over 300ppi at actual print size. Many Epson folks say there's nothing visibly
gained
past 260 and some say even as low as 240. On my HP I can see a diff up to around
300 but not past that.
You might start with the same image, resize/resample to 10" at 240, 260, 280,
300 (go
back to first original image each time) and see what you see.
This doesn't relate to the "grainy" nature of your previous post, I'll let
others comment
on that, lots of variables there, but you might as well nail down the min/max
ppi for
quality printing on your system. Again, if nothing else, you'll save time
printing if you
find no visible improvements past a certain ppi. Also will allow more cropping
from
original image and still get up to reasonable output size and etc.
