Images sizes for large graphics

Hi all,

i'm producing some very large graphics for an exhibition. The image files aren't as big as the panel size.

The panel sizes 600mm w x 1050mm w, and the wall size (for which we need a huge graphic) is 4metres x 2.55metres - the image I need to use is 60omm w x 800mm h. This means that the images are re-sized to 200-350% of the orig size.

Is this going to be too pixelated, does it make a difference to make the artwork 50% of the size, or does that not make any difference when its actually printed?

Any advice would be muchly appreciated!

i would personal up the image size in photoshop and then u can see how pixelated it is. but id also call the printer and ask there advice

what is the uncompressed file size?

You can get away with 150 dpi for exhibition graphics, they are printed on large format printers and tend to be a bit more forgiving than a litho press

Thanks for your replies, I have blown them up in photoshop and they don't look too bad!
