Hello Sheri;

You do not "need" to use the ICC profile for colour correction; but it is highly recommended…

All printing processes generate different colour spectrums, and the BookSmart process is no different.

Make sure your InDesign JPEGs are sRGB colour profiled, then download the ICC profile and "soft-proof" your images using that colour profile. You WILL see that there is a difference… (The images should retain the sRGB profile after correction…)

If you do nothing to the sRGB images, then the final print will almost certainly be different from what you see on the screen… In general dark tones tend to be very dark… That’s the main difference.

You should also ensure that your monitor is correctly colour calibrated for the best results… If it’s not – you could be adjusting colour profiles to suit the monitor output – not the printer output… ( A tool such as Pantone’s Huey does the job quite well…)

Cheers;

Lee

and also: I have a spyder device to calibrate my monitor. Does it matter if I calibrate before or after installing the ICC?

I don’t know how late this my come, but Lightroom has no way to softproof anything. It uses a variation of ProPhoto <acronym caps title="it’s been called "Mellisa <span class=">RGB</acronym>. If you want to softproof anything, it will have to be done in an imaging application such as Photoshop. Sorry if this may be to late, but I just recently found this forum, and I have been reading various posts,some of which is very interesting, and some concerning some aspects of Photoshop are not correct.
