All finalized files should be:
- in .pdf, .tiff or .ai
- Leave a minimum of 3 mm space around the design
- Minimum resolution = 300 dpi, files should be in CMYK (no RGB)
- Text should be vectorized (converted to curves) or embedded
- All layout lines should be removed in the final version
For an optimal resolution, prefer Adobe Illustrator software to create your design.
