i am currently working on publishing a book of my personal photography, and in putting together the book (using InDesign obviously......CS) it would have been helpful to know what resolution my images were going to print at given the particular size i scaled them to on a page.
does anyone know how i can retrieve that information? effective print resolution of a graphic?
Select the graphic with the either Selection (hollow or solid arrow) tool and look in the Info palette...it lists actual and effective resolution, as well as what type of graphic it is and what color space it's in. Hope that helps.
The info pallette will give you the basic information but two other things are more important. (1) Pre-determine the SCREEN resolution with the printer - 150 line, 200 line, etc. Your CMYK resolution in pixels would need to be at least 300 dpi, 400 dpi, etc. to deliver the appropriate line screen. What matters is the proper resolution being achieved on-press which in turn relies on you giving the printer the appropriate resolution to work with in the artwork. (2) In converting to CMYK, the photos should have the proper black, mid and white points set. This will vary from printer to printer and photo-to-photo as each pressand each photo is different. Paying attention to this will give you the best reproduction of your photos. Setting this up properly also includes creating CMYK conversions with 'rich black' settings established by the printer. If the printer cannot give you these settings, get another printer for your book, or be prepared for a less-than-stellar-looking final result.
Finally, as an option you should use a varnish overprint. It really makes the photos pop like originals. The UV offered by many printers is good too but there are many variations of varnish and you can choose the one that is as stark or as suptle as your photos require. Varnishes are usually offered by small art presses like Nexus Press in Atlanta ( http://www.thecontemporary.org/pages/nexuspress/nexuspress.html ).
