The Print Design Proof Checklist
This print design proof checklist is very detailed and covers all the steps that need to be checked before submitting the file to the print shop. It is ideal for reviewing each item carefully before sending the file for printing.
Crop Lines, Safe Area (Margins), and Bleed:
- Ensure that the crop lines are correctly placed and that there is a safe area (usually 3mm or more) from the edge of the design to prevent important content from being cut off.
- The bleed area (usually 3mm) refers to the part of the design extending beyond the crop lines. Ensure that images and backgrounds extend into the bleed area to avoid white edges after trimming.
CMYK and Spot Colors:
- CMYK design files must use CMYK colors to ensure that the color conversion does not affect the design’s tones. No individual CMYK color value should be below 10%, and the total of all four CMYK values should not exceed 250%.
- For specific spot colors, use Pantone spot colors.
- For color matching, refer to the four-color process guide or Pantone spot color guide instead of using screen colors.
Colors:
- For black, use four-color black (C60, M40, Y40, K100) or two-color black (C40 K100) for large black areas, 100% black (100K) for text and fine lines.
- Colors such as purple, brown, orange, dark blue, and dark green are created by mixing three or more CMYK colors and are prone to color variations. Use these colors cautiously.
Image and Text Handling:
- Ensure that all images have a resolution of at least 300 DPI, especially for photos and detailed images. Low-resolution images may result in poor print clarity.
- Make sure all text is converted to outlines or paths to avoid font issues or missing fonts during printing.
- Check for spelling errors.

Post-Processing:
- If the design involves special processes (such as hot stamping, UV coating, embossing, etc.), ensure these processes are clearly marked in the design files, and prepare a separate file for the special process (e.g., black plate for UV coating).
File Format:
- The output file format is typically PDF, TIFF, or EPS, and when outputting, select high-quality settings to preserve the details and color accuracy of the file.
Production Schedule and Shipping:
- Larger print quantities reduce the average unit cost.
- The more post-processing options involved, the higher cost and longer the production time.
- Common printing papers are generally cheaper than specialty papers.
- For large-volume printing, production time and shipping cycles need to be planned in advance, especially considering holiday schedules and international shipping time constraints.
By following this checklist, you can ensure that your design proof meets all the necessary printing requirements, reducing the chances of issues during the printing process. If you have any more printing-related questions or need further clarification, feel free to reach out to us!
