Giant File Size

[jackknife]

Hey guys. I'm working with a new client who is working with a company they haven't worked with before to get a sign made.

The specs are 59in x 59in. To even set up a file that big it is around a gig. Is that normal? They want me to ftp the file(s) and it seems like a gig is huge for one of the 6 files they need. They want the .psd format.

I guess my question would be is there a way to make this files size smaller? Is 300dpi necessary? Having not done work on this scale before I'm confused.

Shocking but yes. 300dpi is a norm (around here that's what we use ) .

In fact some even go as high as 1200.

Logic - think of it as a 5x6" pix blown up to 40 times the normal size. The end result is pixated picture. Even in Photoshop, take a scanned image (2inches x 2inches at 300 dpi ) enlarge it by 500% and you'll see what I mean.

I don't know if it's a norm in your place but a rule of thumb I follow is:

Say - for 16inch x 20inch poster print size, I work on an image size of 1600 x 2000pixels at 300 dpi. For say a 24 x 36 size poster print set around 2400 x 3600.

This means inches x 100 to get the PS image size in pixels.
