To make a custom diamond painting file, start with a high-resolution 300 DPI image, then convert it into a coded grid using software that assigns DMC or diamond color codes to each square. Clean up contrast and background, limit unnecessary color variations, and export the pattern as a printable PDF or canvas file. This approach ensures your supplier or manufacturer can easily print, proof, and package your design for bulk or private label diamond painting kits.
