Most inkjet-style poster printers need only 72ppi @ 100%. I always recommend a "LiteJet" type of output for 3 reasons. 1-You can get away with 100ppi @100% with great results, 2-type if set in Quark/InDesign/Illustrator or vector in Photoshop comes out sharp, 3-It is a digital output to photographic paper (reflective and backlit) so photos retain high-quality and sharpness even close-up. So your image that is 15 x 20 @300ppi would be 45 x 60 @100ppi.</p> <p>As far as under-resolution images, Photoshop will do okay interpolating up to 150% (for my standards), but anything above I use a plug-in called Genuine Fractals- http://www.ononesoftware.com/ The results are amazing with it, I highly recommend it. Depending on how much you need to come up, you might want to wait until you flatten the image to "size it up" if it gets to be too much for your computer to handle.</p> <p>Good luck!

Your Podcast is great, very helpful. Thankyou!

I have a quetion.

I am supposed to make composite images for panels 4 feet x 8 feet. But the original images I have been given for this are 15 inches x 20 inches 300 dpi, many are in LAB. I only need to use about 3 or 4 images per panel which means that the original I have been given need to up-sized if I maintain 300 dpi.

Question would 150 dpi be good enough?

What is the best way to up-size/ In the document? before dragging it into the new document?

And I know this will be a slow process, I am fiddling with a 4 gig file now!

Thanks for any help or advice.

Jen
