I meant more specifically the "Editing for sending to the printer" like 8/16 bits and Tiff or Jpeg and such.
All of those books are specifically about "Editing for sending to the printer".

Nations Photo Lab:
5. What file guidelines does your photo lab require?
We require the following file guidelines:
- -300 dpi [sic] resolution
- -8-bit color depth
- -sRGB color space (we are happy to provide you with our ICC profile)
- -TIFF files must not be layered
- -25 character filename limit
- -NO special characters, excluding hyphen (-) and underscore (_)

Color Calibration & File Management
Q. How do I calibrate to your printers?
A. You don't calibrate directly to our printers. You calibrate your monitor and generate a monitor profile which software like Photoshop uses to show you accurate color on your screen. We calibrate and balance our printers to create a printer profile. Using a standard working color space like Adobe RGB 1998 or sRGB and embedding this in your file allows the printer software at WHCC to use our printer profile to make sure what is printed is what you saw on your screen. We recommend all clients perform hardware monitor calibration. This is a relatively straightforward and simple procedure. We recommend the X-Rite i1 Display.
Q. Do you supply any profiles?
A. Yes. Once you have an account number, you can download ICC profiles for soft proofing purposes. The profiles are for all of our printers and we also have instructions on how to properly use them. Under no circumstances should you convert to our printing profile or embed it in your files.
Q. Is it okay to embed an ICC profile?
A. Embedding a valid ICC profile in your image is very important. Without embedding the profile our software has no idea what colorspace your file is in. This will result in uexpected color in the prints. All files not tagged with an embedded profile are assumed to be in sRGB.
Q. What colorspace do you accept?
A. We accept any colorspace as long as it is embedded in the file. Our software will read the colorspace embedded in the file and print appropriately for that colorspace. We recommend the use of a standard working space profile such as Adobe RGB 1998 or sRGB.
Q. What type of file do you require?
A. We require level 10 JPEG files to be sent to us.
Q. Why a JPEG file and at level 10? Don't you lose quality in the large prints?
A. JPEG compression is a very efficient image compression algorithm designed specifically for saving photographic images. It takes advantage of how we see color versus brightness to only save information needed to reproduce the image for people to view. Image data is lost during compression but at high levels of quality you will not see a difference between a level 10 JPEG and a Tiff printed to paper. JPEG compression is perfect for transient files for sending to the lab for printing but avoid using the compression as a working file type. Also avoid opening a JPEG, making changes, and resaving it again as a JPEG repeatedly. If your workflow calls for this to happen, save your files as Tiff or PSD files until they are complete and ready for output. At which time you should save them as level 10 JPEG. Any JPEG artifacts you see in your prints come from the JPEG file coming out of your camera, not from saving them as a level 10 for output purposes.
