Preferred PDF specification

We can process most PDF files, but for best results please provide your files in the following format:

Ideally images should be 300dpi or above without visible compression.
It's important that we can extract and index the text from your PDF. Please ensure that your text hasn't been converted to vector format - a good way to test this is to select some text from one of your pages and paste it into a word processor. If you obtain legible text, we can work with your file.
Cropped or trimmed
Pages should either be cropped to their final size (with no visible crop marks in the margins) or each page's TrimBox should be set appropriately so that we can trim them automatically during production.
No spreads
Each single page of your physical publication should correspond to a page in the PDF - please don't combine double-page spreads into a single PDF page.
Please provide assembled PDFs where possible, containing all the publication's pages in the correct order (including inside covers). Alternatively, we can accept zip files containing individual page PDFs if the intended ordering of the pages is clear from their filenames.

If you have questions or would like us to review a file for suitability, please get in touch or upload a PDF.
