I don't have specific guidance on exporting from Procreate in the help centre — that's a Procreate-specific question. However, I can tell you what creativehub needs when you upload your files for print:
File format & settings: - Export as JPEG (quality 12, Baseline Standard) or flattened TIFF (no layers) - 300 pixels per inch (PPI) at your final print size - 8-bit colour
Tips: - JPEG at quality 12 with Baseline Standard is fastest to upload with minimal quality loss - If your file is too small for the print size you want, the system will warn you — either reduce the size or supply a higher-resolution master
Once you've exported correctly from Procreate, you'll upload it into creativehub when you create your print products in the SELL app.
For Procreate-specific export steps, check Procreate's documentation or support — they'll have the detailed walkthrough.
