How Convert2Print evaluates print quality, size, scaling and file readiness.
Metrics help you understand what will happen before you generate the final ZIP. They show whether the file is suitable for the selected output size, DPI, ratio and print workflow.
Instead of guessing, Convert2Print analyzes the uploaded file and calculates practical print information.
Convert2Print works with three production DPI targets:
These are output targets. The original file may not always contain enough pixels to support the selected DPI at the chosen print size.
If a PDF or uploaded file does not provide a clear usable DPI target, Convert2Print uses 300 DPI as the standard production reference.
150 DPI is useful for large prints viewed from a distance.
300 DPI is the standard recommendation for most professional print jobs.
600 DPI is used when maximum detail is required.
Images are made of pixels. DPI is calculated from the number of pixels and the physical print size.
If you choose a large print size but the uploaded file has too few pixels, Convert2Print will show warnings in Metrics.
The file can still be generated, but the print may look soft when viewed closely.
The print quality score estimates how suitable the file is for the selected output.
Final print resolution shows the practical DPI achieved after the selected size, ratio and scaling are applied.
Scaling shows whether Convert2Print needs to resize the image.
Heavy upscaling can reduce sharpness and print quality.
The upscale factor shows how much the image is enlarged.
If the selected ratio does not match the original file, Convert2Print may need to crop part of the image.
The preview shows the visible crop area before export.
Illustration metrics focus on print size, DPI, ratio, scaling and expected print quality.
They help you decide whether the chosen size and ratio are suitable for artwork, posters and print designs.
Photo metrics show the selected output height, calculated width, output pixels, embedded ICC profile and output DPI.
Photo mode uses sRGB automatically.
PDF metrics check document structure and print readiness.
PDF/X-4 metrics show whether the file follows a print-ready PDF/X workflow.
TAC means Total Area Coverage. It measures how much ink may be used in the darkest parts of the print.
Too much ink can cause drying problems, smudging or unstable print results.
The Recommendations section helps you choose safe print sizes.
Your file is usually production-ready when Metrics shows:
