Will need to know what "dot gain" that I should allow for in CS3?
Am going to have a book printed soon enough, yet before the huge work starts of preparing images for press, it would be nice to know what I should set the "Dot gain" to keeping in mind the matt quality of paper used. The standard/default setting in Photoshop is set to 15% and also happens to have the same color profile that "Blurb" uses to print with; "sRGB IEC1966-2.1" I would just like to confirm this ( correct %) with somone before I start work on my images. Also confirm the color profile above while I´m at it ;)
Have naturaly searched the forum for this info… Many thanks for any info.

Howdy, The 15% dot gain is pretty much standard. I know that in newsprint, one must anticipate slightly higher dot gain (20% +) since the paper absorbs more ink and things get a little messy. But for the 80 # semi-matte paper we use, the standard 15% setting is fine. Also, that’s getting a bit academic since BookSmart makes copes of images anyway, and not all of that image’s attributes are preserved. That’s the same reason why you should soft-proof with the generic color profile for the machine used to print our 8×10 and 13×11 books, but needn’t assign nor convert to the profile. Simply check View>Proof Setup>Custom and choose the profile that you can download from the following website:
http://www.bonsai-photography.com/ That site also includes directions on how best to use the profile. Please note that this will help get consistent color, but that Blurb doesn’t guarantee precise color management at this time. The sky should be blue, grass green and skin tones accurate. But corporate logo colors, for instance, just like any other shade, are subject to slight variations for print run to print run. Hope this helps! Cheers,
Jeremy

Many thanks Jeremy, Sorry I did not check back sooner for the quick answer. I have gone with the 15%, yet thought it might be rather high for your technique.
However now more concerned with the color difference you speek of, let´s live in hope. I have also tryed the HP color ICC profile you mensioned, yet cannot realy rely on the effect when similating paper is turned on, all goes to hell! Will still live in hope. Many thx - Steve
