What is the highest possible print resolution in book publishing?

I want to publish an art book with a major publisher. I need to finish my artwork and then approach publishers, so I cannot ask for printer specifications beforehand. My art is digital, and I want to create it with the option to print it at any common unknown printer.

I understand that for normal purposes it is enough to create images at a resolution of 300ppi. But suppose, for the sake of this question, I wanted to print my art at the highest possible resolution that common art book printing allows.

What is the highest possible output/printer resolution (dpi, lpi) in printers that print art books for major mainstream publishers?

And what is the best digital file resolution (ppi) for that output resolution? Identical (bitmap), double (300dpi => 150lpi), quarter (pixel to CMYK), ...

And finally, does the resolution differ for K as opposed to CMY? That is, does black have a higher possible resolution than color, because, I assume, that text is not printed at "300dpi" in books.

^{I am not talking about PoD, Small Press, or specialized high end single print art print photographic printing, but printers that print illustrated books of artistic photography or museum art such as you find in the coffee table book section of a bookstore.}
