Design & Printing Tips:
- **Resolution:** Ensure your image resolution (DPI/PPI) is sufficient for the target print size (e.g., 300 DPI for high-quality prints).
- **Bleed:** Add a bleed area (extra margin) to your design if it goes to the edge of the paper to prevent white lines after cutting.
- **Color Mode:** Use CMYK color mode for print designs, not RGB, for accurate color representation.
- **Aspect Ratio:** Maintaining the aspect ratio prevents your design from looking stretched or squished when resizing.
