does anybody know how the resultion the books are printed ?
Because I use the Nik Output sharpener tool.
I assume the books are printed by any color laser system and so I would have to choose the halftone setting(?). But than I have to know the Lines /inch. for optimised settings of the Nik tool.

    I don't have a loop handy to look at a book - but I'm not aware of a LPI setting - they use photos up to 300 dpi and give you a warning if the photo is less than 180 dpi

    The Apple tips do not address this - http://www.apple.com/support/photoservices/preparation_tips/

    I would think that setting for a 300 lpi halftone screen would work fine - I have printed photos in books down to around 150 dpi with outstanding results (300 dpi ones are better - but the lower ones look very good

    It certainly is not the same as an offset printing system

    Now I have a loop - unlike traditional lithography the dots vary in size and shape but are all very small - I roughly counted 15 in 1/16 inch - if I counted correctly on that part of the photo that would be 240 dpi

    I'd go for 300 dpi and see how you like the book - I think it will be pleasing
