ICC profiles BASIC Question

I’ve read some posts on ICC profiles, but I’m lost.  I have also had problems with the color and the exposure when printing past books in blurb.  I’m about to begin a new one and want to get it right.  My questions are:

 1)  Should my photos be in sRGB rather than Adobe RGB?  If so, I have over 400 photos I will have to go back to Photoshop to change them?

2)  The purpose of using the ICC profile is so I can print a copy and evaluate the colors before uploading, is this correct?  If so, where can I get the ICC profile and how is it uploaded?

Thank you in advance,

Freddi

Hello Freddi;

1. YES – your images MUST be in sRGB for optimum results. You can probably set-up an "action" in PhotoShop to do a mass change without needing to do it image by image…

2. The purpose of the ICC Profile is so you can best prepare your images in sRGB format for ultimate printing using a CMYK process. There’s a lot of colour conversion happening between those two processes… (CMYK is a commercial process..)

Check-out; http://blurberatiblog.com/index.php?s=ICC+Profile&Submit=Search and follow the links to download the profile.

Do a forum search for "ICC". You will get a multitude of hits which will give you more information about the whole process…

Cheers;

Lee

Hi Lee-have you had experience with the indigo5000 profile on blurb? I am doing a new book on my black and white photos and experimenting with several differing settings for optimal black and white image. The book test shows some of this:
