The artwork file directly affects printing quality, color accuracy, cutting position, sealing area and overall packaging appearance.

Frequently Asked Questions
What file format is best for packaging printing?
AI (Adobe Illustrator) is the preferred format because it supports vector graphics, editable text, dieline layers and CMYK color mode. PDF with embedded fonts is also acceptable. CDR files can be processed. JPG and PNG are for reference only, not for final printing.
Can I send JPG or PNG for printing?
JPG and PNG are not suitable as final printing files because they use RGB color mode, lose resolution when scaled and cannot be color-separated for printing. They can be sent as visual reference, but vector files (AI, PDF, CDR) are needed for production.
