Start Here
Step 1: Gather and Prepare Digital Proof and Finished Product Images
"I have a finished print product and the original digital proof. What details do you need from me to start a comparison?"
Goal
Ensure you collect clear, representative images or files of both the digital proof (PDF, image file) and the physical product (high-resolution scan or photo) as the basis for quality comparison.
Example
I have a proof_final_banner.pdf
for the digital proof and a smartphone photo of our finished banner (2024-BannerResult.jpg
).
Variations
- "Here are both the PDF proof and a JPG scan of the finished sign. Can you compare them?"
- "Can I upload multiple views of the product for a more thorough check?"
Troubleshooting
- Low image quality: Retake the physical product photo or scan in better lighting with higher resolution.
- File format issues: Convert files as needed (e.g., export PDF to image or resave photos as JPG/PNG).
Step 2
Step 2: Submit Materials and Request AI Comparison
"Here is the digital proof and the finished product image. Please identify any visual differences or print defects such as color shifts, misalignments, or missing elements."
Goal
Use the AI to automatically compare the finished product with the approved digital proof, focusing on highlighting significant discrepancies that could impact quality.
Example
I uploaded both files and requested: "Please check for any color inconsistencies, text misplacement, or extra marks between the proof and product image."
Variations
- "Highlight any differences in logos, text, and color shades between these two files."
- "Check for missing design elements or unwanted print artifacts."
- "Do you see any registration issues or blurring on the finished sign compared to the proof?"
Troubleshooting
- Upload errors: Ensure files meet platform requirements and retry; contact IT if issues persist.
- AI not detecting obvious issues: Clarify specific areas of concern or attach higher-quality images.
Step 3
Step 3: Review AI Findings and Recommendations
"Please summarize the key discrepancies detected and recommend actions or next steps for resolving quality issues."
Goal
Understand the AI's comparison report, including a summary of detected discrepancies (e.g., color drift, misaligned elements), and obtain actionable recommendations for resolving quality problems or proceeding with delivery.
Example
Summary: "Color on banner background is darker than proof. Text at bottom left is misaligned by 0.5". Recommendation: Reprint with corrected color settings and check alignment."
Variations
- "Can you provide a checklist of items to verify based on these results?"
- "Suggest process improvements to prevent similar issues in future jobs."
- "Is it possible to highlight discrepancies visually on the images?"
Troubleshooting
- Unclear results: Ask for a more detailed side-by-side comparison or request visual markup on errors.
- Uncertain recommendations: Request industry-standard tolerance guidance or clarification from production lead.
Step 4
Step 4: Document and Archive Quality Check Results
"Please generate a summary report of this quality check, including detected discrepancies, actions taken, and final approval status. Format as PDF or paste summary below."
Goal
Record the outcomes of the AI comparison and decisions for internal tracking, compliance, and continuous improvement. Ensure all findings, actions, and approvals are clearly documented and easy to retrieve.
Example
Generated report includes: project name, customer, date, summary of findings, corrective steps taken, and a final sign-off section.
Variations
- "Output a text summary for me to paste into our QC log."
- "Can you generate a PDF report suitable for client review?"
- "Add this result to our internal Google Drive folder with a standard file name."
Troubleshooting
- Formatting issues: Specify desired format (plain text, PDF, table) and retry export.
- Data not saving to system: Manually save report while IT investigates integrations.
