Preparing Images for Photobook

[kpdesigns492]

I've been wavering back and forth about the best course of action to sharpen images for my photo books that will be printed on an HP Indigo at Sharedink. Do you think the below steps will yield good results?

So far my process has been:

1. Edit images in Lightroom (color correction, exposure adjustments, and capture sharpening, etc)
2. Output full sized tiffs (no output sharpening) to a folder and then import them into my Indesign layout.
3. Once finalized, I run a script to resize all images in InDesign to 100%.
4. I'd like to apply some output sharpening to these re-sized images and was wondering if importing the images into Lightroom and then exporting them with output sharpening set to Matte Low Setting would yield good results. I don't need a ton of sharpening. I'm just concerned that the Lightroom sharpening is not optimized for Halftone output.

Thanks for any advice.

I think that ought to work well.
I use a similar workflow for Blurb, but use PKS2 to sharpen the resized images via a Photoshop action and the image processor script.
