Book Printing settings

[Христо България]

Hello, I need your help. I am writing a book, which is A4 format, with landscape photos in it with a size of 18 cm. width and 13cm height. First question - on an A4 sheet, what would be the most appropriate height/width ratio. Second question: in Lightroom, what parameters should I set to preserve my colors as much as possible. I have 300 photos in the book so I'm looking for your help. My email is h.hristov29@abv.bg I await your reply. Thank you.

All of this is a conversation you must have with the print provider.

Preserving colors from raw data would be, at the least, exporting in ProPhoto RGB/16-bit, but again, after that, it's all based on the print provider. You'll need some conversion to a defined CMYK output colorspace.

Thank you very much, I won't waste my time redoing them before I've spoken to the book printer. Thank you very much, stay healthy
