Overview
ISO 22550:2021 - "Document management - AFP interchange for PDF" defines how Advanced Function Presentation (AFP) is used as a container format for document objects, specifically to include single- and multi‑page PDF objects within an AFP Mixed Object Document Content Architecture (MO:DCA) file. The standard describes identification, resource pairing and management for embedded PDF content and explains how PDF external file references map into AFP secondary resources (see Annex A). It is intended for AFP + PDF workflows where final production is managed in an Intelligent Printer Data Stream (IPDS) environment.
Key topics and technical requirements
- AFP MO:DCA container: Specifies the AFP interchange set (IS/3 with the graphic arts function set) as the file format for mixing AFP and PDF objects.
- PDF as non‑native presentation object: Defines inclusion of single- and multi‑page PDF document objects as an AFP function set, enabling PDF content to be treated as AFP objects.
- Resource pairing and mapping: Mechanism for pairing PDF resources and mapping PDF external file references to AFP secondary resources (illustrated in Annex A).
- Conformance rules: AFP MO:DCA file integrity requirements include:
- All structured fields and triplets must be AFP‑defined and conform to AFP object structure.
- Required envelope fields: Begin Print File (BPF)/End Print File (EPF) and Begin Document (BDT)/End Document (EDT).
- AFP with PDF must identify the MO:DCA Function set with specific function set identifiers.
- Structured Field Introducer (SFI) Flag byte set to X'00' and maximum structured field length limited to X'7FF0' (32,752 bytes).
- Compatibility notes: AFP supports other non‑native formats (e.g., TIFF, JPEG) and leverages AFP’s object‑oriented structure for efficient reuse of fonts, images and color resources.
Applications
- High‑volume transactional printing (bank statements, utility bills, invoices)
- Hybrid workflows that create content in PDF and require AFP management for high‑speed production
- Print server, IPDS printer and production RIP integration that must handle both AFP and embedded PDF objects
- Archiving and document management systems that preserve PDF content inside AFP containers for audit, accounting and long‑term retention
Who should use this standard
- Print operations and service providers in transactional and transactional‑marketing printing
- Printer manufacturers, RIP and print server developers
- Enterprise content management (ECM) and document management system integrators
- Software vendors building AFP‑PDF hybrid workflows or IPDS production pipelines
