Uncoated books
Working with books printed on uncoated stock
Before opening any files
Everyone working with files to be printed on uncoated paper stock MUST make sure their InDesign colour management setting is set to uncoated paper before opening InDesign documents. This is because our uncoated setting changes the colour numbers of files, to retain colour accuracy but will change pure process colours into combinations. For example mono black will become rich black. Illustrator and Photoshop setting remains unchanged.
So set your colour management in the CS applications like the table below, and use the export setting shown.
| Workflow | InDesign | Photoshop | Illustrator | PDF export |
|---|---|---|---|---|
| Coated | …Coated_Fogra39 | …Coated_Fogra39 | …Coated_Fogra39 | …Coated_Fogra39 |
| Uncoated | …Uncoated_Fogra47 | …Coated_Fogra39 | …Coated_Fogra39 | …Uncoated_Fogra47 |
Uncoated InDesign colour management
The colour setting to use is PRH_Colour_Settings_Uncoated47 and the Profile it refers to is PSO Uncoated ISO12647 (ECI). The ink limit (TAC) for this profile is 300% for any manual tint or image adjustments and this number should not be exceeded. For uncoated books printed at Clays, the TAC must be reduced further to below or near 240% using Photoshop to colour adjust.
The uncoated setting can be downloaded from the default colour management page.
Different colour management setup?
If you are already using a different or default colour managed workflow or have received files that use differing colour profiles to Penguin Group guidelines (you’ll get a mismatch dialog box for different settings), please read the Colour Management page which has instructions on how to change to our custom profiles.
InDesign image colour setting check
The uncoated colour management policy will convert all images to the correct Uncoated profile on output. Images with differing profiles (RGB or CMYK) should be placed into the uncoated InDesign document and allow the colour management to be handled automatically.
The only change to this rule should be with Co-editionable images. A Co-Editionable images set-up guide can be found here
Photoshop and Illustrator images
While you MUST NOT change the colour management setting in Photoshop or Illustrator, you should check your images using the Proof colours option set to uncoated colour profile PSO Uncoated.
Making uncoated CMYK PDFs
