I have a poser picture that i want to print and frame It will be 8X12 -- what is the best dpi that should have to have it come out nice  -- I will be using hp image zone

Thank you to all who respone!

300 dpi is the normal print resolution so you'd want to be rendering at 2400 by 3600 pixels (8x300 by 12x300)

You should first find what is max resolution of printer you will be using.
A lot of the older printers are 300 dpi, newer ones range from 600-2400 or more.
Also, don't forgets to add a border if you are stretching to frame or just matte.
I usually send out to service like redbubble or deviantart because they have nice printers and can color manage (also they have the frames)

You can save them as jpgs (if you're not into professional-level), or another format (tiff? even bmp?)

Then you can possibly drag them into a program that handles pictures and prints from it; the trick is to pick the size, and check your aspect ratio, to avoid stretching, etc.

I just had a chance to print a poster from one of my Poser pics at 24x36; it's off-center with no borders, but that's me...looks cool, tho...;)

stay tuned for more helpful answers...;)

I would save into a different image format other than jpeg.  Jpeg is a very lossy format and will deteriorate very quickie it you decide to do any post work.  Convert as needed.

If you could trim that pic back to 8 x 10 you can get prints at WalMat for just under $3 per print. You can do smaller test prints starting at 10c a print.  I have made a small set of prints of major props and scenes for reference. 

It's no necessary to use such high resolutions for printing, computer screen resolutionis something complete different than printer resolution.

See the next link:

I get a perfect A4-print (which is about 8 x 12 inch) on my HP photosmart  Pro B9180 inkjetprinter with a render of 1272 x900 pixels.
Printers need more dpi to get the same color as a computer screen.

It will save you a lot of rendertime.
