Direct answer
In a custom Mahjong project there are usually several kinds of files: the artwork the buyer supplies, production files the factory adapts from it (such as engraving paths, color separations and print layouts), packaging dielines, and machine programs. Ownership of each can differ. As a rule, the buyer should own its original artwork and brand assets, and should agree in writing who owns adapted production files, whether the buyer receives copies, and whether the supplier may reuse any of it. Settle this before production, not after a dispute.
This is general information, not legal advice.

Key takeaways
- Different files, different questions. Original artwork is not the same as a machine program.
- Buyers usually own their original artwork and brand marks.
- Adapted production files need a written agreement on ownership and access.
- Ask for copies of approved production files if you may change suppliers.
- Restrict reuse of your designs by the supplier.
Types of files
| File | Usually created by | Ownership question |
|---|---|---|
| Original artwork | Buyer or buyer's designer | Buyer should hold rights |
| Logos and brand marks | Buyer | Buyer |
| Adapted production files | Supplier, from buyer art | Agree who owns and who gets copies |
| Engraving or print programs | Supplier | Often supplier tooling; agree access |
| Packaging dielines | Supplier or packaging partner | Agree reuse and copies |
| Sample photos | Either | Agree use in marketing |
What to put in writing
- Buyer retains ownership of its artwork and brand marks
- Who owns adapted production files and dielines
- Whether the buyer receives copies, and in what format
- The supplier may not reuse the design for others
- Whether the supplier may show the product in its marketing
- What happens to files if the relationship ends
See OEM vs ODM vs private label. A confidentiality agreement (NDA) can protect unreleased designs during development.
Designer rights
If a freelance designer created your artwork, make sure your agreement with them transfers or licenses the rights you need for commercial products. Fonts and illustrations need commercial licenses too. See IP and typography licensing.
Version control
Keep a folder of approved files with version numbers, matched to your approved sample. See custom Mahjong artwork files and reorder consistency.

FAQ
Does the factory own files it adapts from my artwork?
It depends on your agreement. Write down who owns adapted files and whether you get copies.
Can the supplier sell my design to others?
Not if your agreement prohibits it. Put this in writing.
Do I need the factory's machine programs?
Usually not, but you should have the approved artwork and production layouts so another supplier could reproduce the design.
Who owns sample photos?
Agree whether each party can use them in marketing.

Production notes
Artwork guidance is a preparation aid. Minimum line widths, color matching and marking methods depend on the material and approved sample.
