I submitted a pdf file to Signs 365 for a 4' x 16' banner and the file size was only about 15 KB. The identical file in a high res jpg was around 63 MB. The first one I ordered came back and looked fine, but it still made me nervous sending such a small file. What is the discrepancy, or in other words, how dey do dat?

Just a guess Sonny...
But did you send the PDF as a vector file...that would be a much smaller file size and obviouly perfect.

...but if it had shadows, they'd probably get messed up!

the size of the file is dependant on how the code is written for that particular extension. you have the same thing with .wav files are way big, same song in .mp3 is less then 1/2 as big. .ai & eps can be huge, .tiffs are also. take an .eps into corel that is huge, save as a .cdr and its almost nothing.

it is called file compression,....it's kind of like when they take a Styrofoam cup down in a deep sea submarine and end up with a cup the size of a child's toy tea cup. the jpg when open can be large but when you save it to a file it is compressed and the computer takes out all the extra space to make the file smaller,...for example
file is open and uncompressed,...
fileissavedandcompressed,...
jpg's by their nature consist of numbers designating a color for each pixel,for a whole row of pixels,,if all the pixels are the same color on that row the file format allows for a much smaller code to say use the one number for all 800 numbers in this row,instead of repeating a 16 digit number 800 times,...

The PDF would be all vectors...simple!

Whatever software you're using to make the PDF - Always check the settings to if it's changing the resolution and color mode on your bitmap. Check to see what it's doing to jpg quality as well... too low and you'll get those nasty jpg artifacts that look like pimples. Be safe.

Sonny, PDF is all I use to order with from 365 and have never had any issues with colors or resolution whether it's a Vector or Raster. (Once you get Signlab's palette corrected to cmyk) I am still using Adobe Creative suite CS4 so Acrobat is installed as a printer so you just need to change a few settings in Acrobat.
Open up your acrobat properties from the printers management window. Click on Printing Preferences. on the drop box of default settings click on High Quality Print. Then click on Layout then Advance. I have my Print Quality set at 1200dpi ICM Method: ICM Disabled (I have Signlab set up to do all my color correcting) Scaling 100%
Then after that when I go to print a banner or whatever I just go to my layout/Advance/Paper Size/postscript custom page size and enter the page size to whatever size I am printing at full size. Print and order.. Once you have Acrobat set up it takes a whole 2 seconds anytime after that.
