Of coure i can do file in prefered cmyk format but i think if they do better job what they say is better for their. and many my book visions are photo related much i mean good colors are important part of it.(some books little distortions in colours are not so bad thing).

PDF/X-4 combined with any CMYK output profile in your document setup will export rgb images intact (i.e., they are icc tagged rgb images in the pdf), CMYK images will output as Device CMYK in the pdf, and text will output exactly as defined in your APub document. So text that is defined in CMYK colors, including 100%k will remain so in the pdf. Any text designed in RGB will be output in its corresponding CMYK components (i.e., RGB text will be converted to CMYK). Any vector elements will become Device CMYK.

At least when i put srgb picture document what is cmyk mode srgb picture converts to it. in srgb mode cmyk values i bet is converted to srgb. different elements now looks cannot be iat least i dont get work be different colour space. i understand this is possible with indesign. i very sure it converts it becouse colours are changed when i look final pdf (i tested two colours what i know cannot be printed rgb cyan and blue). and this service recommends make pdf this way what i talk. least i understanded this way. saddly how is done i dont found text in english. at least preview in computer looks all pictures are in cmyk i think these srgb pics should look different if all goes way what i mean.
