RE: Large print - quality issue

[Pini Vollach <pinimage@xxxxxxxxxxxx>]

The native resolution of some printers (Epson  included) is 360dpi . It is recommended to use this res instead of 300.

With magnifying glass I can see difference between 360dpi and 720 but not with my bare eyes.

Bit depth just gives you more colors. Most printers only handle 8 bits. You will get smaller file size at 8 bits. You won't get any better quality over 300 dpi. Some text does print better at 600dpi but in your case you file is already too large. I don't know if zipping throws away pixels (ie lossless or lousy)

Dimensions and resolution I understand, though Bit depth is something I'm unsure about...I have the choice of 8 or 16 bits, and I'm presuming if I choose 16 bits it will be better quality, though I don't know this for sure...any one know much about this? I've tried using it and it certainly increases the files size...so much so that when I have a final composite psd the file size exceeds 2gb, which makes it difficult to save unless I zip it!  Also, if I choose a higher resolution setting than 300PPI will that actually increase image quality?
