Photoshop Image Size for Large Images

[PostNet]

I have two jobs that are eating my lunch. One is a 8'x25' window perf for a local shop and one is a 20'x40' wall mural. I keep beating my head against the wall trying to set the image size in Photoshop only to have my changes take 10 minutes to process. Is there a better way to do this than to design at 100% at 150 dpi? Help please....

full size @ 72dpi 8bit cmyk
-or-
10% @ 720dpi 8bit cmyk

You are probably dealing with files too large for your PC to handle. You could probably get away with 72 instead of 150 as well.

I can offer suggestions, but they all include computer upgrades. More RAM, Scratch Disks, and RAID all help.

Building computers to handle these size files are our specialty. We build/sell computers for this exact purpose.

It speeds it up a lot, thank you. What impact will it have on the printed image?

With perf, im pretty sure 150ppi @ full scale is completely overkill so don't do them at that resolution because it will only slow you down. Even the 70/30 perfs won't show the quality loss.

Normally I'd say keep the resolution at 100-120 dpi (I find 72 too low for my tastes).

But being as this is going onto window perf you have a ton of leeway. Drop the resolution and save the headaches. You'll never see the difference.

I agree, given that it is window perf you can get away with reducing the resolution quite a bit. A couple weeks ago we finished a perf job that was 18'x36' and the file was built at 50dpi, when printed they looked like a million buckes, even up close.
