The material in these guides is recommended for advanced users – such as creative professionals – who require the highest possible precision in rendering color. For most users, an understanding of the advanced concepts of color management is not necessary to produce a great-looking book with Blurb.

Once you’ve calibrated your monitor and installed the Blurb ICC Profile, you are ready to prepare your images for Adobe InDesign or PDF to Book. For information about image prep for Blurb BookWright, see How to Prepare Images for Blurb BookWright using Adobe Photoshop.
For Adobe InDesign or Blurb’s PDF to Book workflow we recommend that final submitted images be placed into your page layout application in the CMYK color space. In addition to your images all graphics and page layout elements should be created in the CMYK color space to ensure greatest color accuracy of your printed book.
There are two options for working with images within a color-managed workflow:
Option 1: Working in RGB – Soft proofing, converting to CMYK, and saving.
Option 2: Working in CMYK – Soft proofing and saving.
If you prefer to work in RGB, open and edit your images in RGB, soft proofing the images as you work with the Blurb ICC Profile.
When Soft Proof is on, your image title bar will indicate “RGB/8/Blurb ICC Profile” You can toggle the soft proof on/off by using View > Proof Colors.
Once your RGB images are edited and the soft proof is satisfactory, convert your image with Photoshop to CMYK using the Blurb ICC Profile:Figure 3. Convert to Profile
Save the converted CMYK image as a TIFF or PSD file embedding the Blurb ICC Profile. The image is now ready to place into your Page Layout Application like Adobe InDesign®.
If you prefer to work in the CMYK color space, open your image and convert it using the Blurb ICC Profile.Figure 4. Convert to Profile
When Soft Proof is on, your image title bar will indicate “CMYK/8/Blurb ICC Profile.” You can toggle the soft-proof on/off by using View > Proof Colors.
Save the converted CMYK image as a TIFF or PSD file embedding the Blurb ICC Profile. The image is now ready to place into your page layout application like Adobe InDesign®.
This workflow assumes you have Adobe Photoshop® to edit and convert your images. At this time Adobe Photoshop® is the only application that we support, but if you are using another application that supports color management for image editing, it’s possible that this workflow will also work for you.
