You should talk to your printer about this. Things like ideal image formats and color spaces depend a lot on what kind of printing it is, what printing rip they are using, or even the specific hardware they are printing with.
Hi guys, I'm trying to get something color-printed as a TIF so that I can keep all the image information. In the image control box, I have several options for "Image Type": 8-bit color, 16-bit color, 16 bit SGI LogL, 32-bit SGI LogLUV. Which is the best? And there is a checkbox for store Alpha Channel. What is that?
