How do I ensure my creative file approval process with a creative spec validator is compliant with resolution and format rules?

To make your creative file approval process compliant with resolution and format rules, you want the validator to enforce the requirements before a file can be approved or published.

Here’s a practical approach:

1. Define the rules clearly in your creative spec

For each asset type, specify:

• Accepted formats: e.g. JPG, PNG, GIF, MP4, HTML5
• Required resolution / dimensions: e.g. 1080x1080, 1200x628
• Allowed aspect ratios: if relevant
• File size limits
• Color mode / transparency rules if needed

2. Validate files against the spec automatically

Your creative spec validator should check:

• File extension and MIME type match allowed formats
• Pixel dimensions match required resolution
• Aspect ratio is within tolerance if exact dimensions aren’t required
• Frame rate / duration if video creatives are included
• Compression or encoding rules if applicable

3. Block approval on failures

Set the workflow so that:

• Files that pass validation can move to approval
• Files that fail validation are rejected or returned with errors
• The validator returns specific, actionable messages like:
  • “Expected PNG, got JPG”
  • “Required resolution is 1080x1080, got 1024x1024”
  • “File exceeds maximum size of 5 MB”

4. Keep the validator aligned with the latest spec

To stay compliant:

• Version your creative specs
• Update validation rules whenever platform or campaign requirements change
• Log which spec version was used for each approval

5. Add manual review only after automated checks

Use automation for objective checks like format and resolution, then let humans review:

• Branding
• Copy
• Legal disclaimers
• Visual quality

6. Test with positive and negative examples

Before launch, verify the validator with:

• Valid files that should pass
• Invalid files that should fail
• Edge cases, such as borderline dimensions or unsupported formats

Example workflow

1. User uploads creative file
2. Validator checks file type and resolution
3. Validator compares against creative spec
4. If compliant, file is marked “ready for approval”
5. If not, user gets a rejection reason and must resubmit

If you want, I can also help you design a sample validation checklist, JSON schema, or pseudo-code for implementing this workflow.
