hello,

am designing a large poster design which is 30 feet length and 4 feet hight, i had never done so large size design in photoshop, should i defined 30 X 4 feet in photoshop document size or just 30 X 4 inch is enough ? i think if i had to define tht size as actual output size then my computer couldnot support such a large file size because of memory. i heard that in flex print, it would be enough to define 30 X 4 inch for that output size because its print technology is different that paper printing.please suggest me.

and also tell me something about flex print technology, is it same like four color paper printing?

would be greatful to your great suggestion.

thanks

Have you asked the service bureau what the require for resolution? For instance, if they want 360"x48" at 72dpi, it is the sample pixels as 86.4"x11.52" at 300dpi or 30"x4" at 864dpi. All these examples are 256mb uncompressed flattened files.

If you know the name of the printer, try to find specs on their website. One site I found googling was sa-rigging.com and they suggested 300dpi at 30-50% actual size. Using the 50% guide, create it 180"x24" at 300dpi, or 90"x12" at 600dpi.

Depending on your design, you might be better creating it vector in Illustrator or Corel since vector never resamples resolution (like raster) when enlarging.
