All colour scans used should be pre-separated into CMYK colour space. Do not include any colour management profiles or Adobe PhotoShop’s “PostScript Colour Management” as this can cause CMYK data to be converted to LAB by Acrobat Distiller. We recommend a target resolution of 300 dpi at printed size for all scanned images. (150 dpi should be considered a minimum – some loss of quality may be noticeable at this level).
Before supplying PDFs please check that the following points have been addressed
- All files are named so that they list in correct running order when viewed in alpha-numeric order, with a version number and PDF suffix.
- All fonts are embedded.
- All PDFs have been created to the same document size and page size and the page image is centred in the media box.
- For perfect bound and section sewn work an appropriate spine bleed is included.
- Adobe PDF Preset should be of “Print Quality”
