PDF Profiles
The pdf_profile field controls the PDF/A compliance level of the generated document.
Supported Profiles
| Profile String | Standard | Features |
|---|---|---|
"" (Empty) | Standard PDF | No specific compliance. Smallest file size. |
pdfa-1b | PDF/A-1b | Archival (Basic). Widely supported. |
pdfa-2b | PDF/A-2b | Archival (Basic). Supports transparency. |
pdfa-ua1 | PDF/UA-1 | Universal Accessibility. Strict tagging requirements. |
pdfa-1a | PDF/A-1a | Archival (Advanced). Accessible. |
Validation Errors (E002)
If a non-empty pdf_profile is provided, it MUST be one of the supported strings above.
CAUTION
Providing an invalid or unsupported profile string (e.g., pdfa-4u) will result in an E002 Error Overlay on the PDF.
TIP
If you do not require specific PDF/A compliance, leave pdf_profile as an empty string "". This is the recommended default for general purpose printing.
