callas software: pdfToolbox, pdfToolbox Server, pdfChip, pdfaPilot
PDF creation, preflight, correction and archiving for publishing and print production
Print and online production face similar pressures today: fluctuating job volumes, short lead times, and tight margins demand automated PDF workflows and consistent quality assurance.
callas software solutions enable cost-effective automation of your PDF processes in publishing, prepress, and web-to-print. Creative agencies, publishers, print shops, brand owners, and OEMs rely on callas pdfToolbox, pdfChip, and pdfaPilot. We offer the complete portfolio.
callas pdfToolbox
callas pdfToolbox enables the inspection, correction, and processing of PDF files for print production and electronic publishing. Color management, imposition, conversion between PDF standards (PDF/X, PDF/A, PDF/UA), barcodes, metadata, and many more functions.
Preflight profiles check incoming PDFs for compliance with ISO standards or Ghent Workgroup specifications. Checks report problems, fixups correct them automatically. A large number of pre-built checks and fixups ships with the standard setup, plus JavaScript-based custom checks for specific requirements.
pdfToolbox is available as a desktop version for macOS and Windows (including as an Adobe Acrobat plug-in), as a server version for scalable processing, and as a CLI for integration into scripts and automation.
callas pdfToolbox Server
pdfToolbox Server is the backbone of automated PDF processing: watch folders, REST API, Docker container support. Since version 17, callas software also provides Docker images that ship a REST API and support queueing. It connects to existing systems like Enfocus Switch, MIS, web-to-print platforms, or directly to webshops.
Scaling happens through the pdfToolbox Dispatcher: workloads distribute automatically across multiple server instances or satellite systems, with prioritization, failover protection, and load balancing.
We have supported over 200 pdfToolbox Server installations across Europe, with a DACH focus and customers worldwide. Setup options: on-premise (Linux, Windows, macOS), in the cloud (AWS, Azure, Hetzner), under Docker, or hybrid.
callas pdfToolbox CLI
The command-line variant of pdfToolbox Server. It provides the same processing logic as the server and integrates directly into shell scripts, batch jobs, cron jobs, or any other automation. Ideal for customers who do not want to run a server instance but instead embed processing into existing scripting environments.
callas pdfChip
pdfChip generates single- and multi-page PDFs from HTML files. It fully leverages CSS and JavaScript and supports CMYK, spot colors, XMP metadata, PDF standards, barcodes, and variable data. Ideal for variable data printing (VDP), transactional printing, or web-to-print systems that use HTML as a template format.
callas pdfaPilot
pdfaPilot is the specialized solution for PDF/A: creation, validation, and conversion of PDF/A files to ISO standard. Supports PDF/A-1, PDF/A-2, PDF/A-3, and PDF/A-4 for long-term archiving. Ideal for organizations with compliance requirements in digital archives: banks, insurance companies, public administration, publishers.
callas pdfToolbox Dispatcher
The Dispatcher distributes PDF processing tasks across multiple machines or instances. Automatic load balancing, failover protection, job prioritization, and seamless integration into existing workflows. We contributed to the development of the Dispatcher together with callas software.
callas License Server
Central management and distribution of licenses for callas products within a corporate network. Dynamic allocation, scalable, resilient. Manages licenses for desktop versions as well as time- and process-optimized license models for the server products.
What’s new in pdfToolbox 17
On April 30, 2026, callas software released pdfToolbox 17. The most important new features:
- New Docker images with integrated REST API and queueing, available on DockerHub
- Imposition Wizard for quickly configuring imposition setups
- Enhanced JavaScript functionality for automated workflows
- Improved Process Plans with more control options
- New preflight check to detect available space for markers in print-and-cut workflows
- WebP image conversion support
- Extended options for analyzing and correcting problematic PDF content
- New OEM Nesting Module as a separate add-on for automated production systems
Version 17 focuses on automation, usability, and performance in production environments.
Integration of callas pdfToolbox
pdfToolbox integrates into practically any publishing or print production environment. Four typical integration classes:
- Enfocus Switch: native Configurator integration, automated handover of jobs to pdfToolbox Profiles or comprehensive Process Plans inside Switch flows. Details on our Enfocus hub page.
- n8n: through our own callas pdfToolbox REST Node for n8n, which brings the REST API directly into n8n automations
- Webshops and web-to-print: direct connection to Magento, Shopify, specialized web-to-print systems, or your own platforms
- MIS systems: print MIS such as PrintPlus, Multipress, or your own solutions via REST, CLI, or Configurator
Which industries callas pdfToolbox fits
The callas products cover five segments with distinctly different requirements and data volumes.
Commercial print: classic prepress with changing customers and varying data quality. pdfToolbox checks incoming print data against your standards, corrects automatically and imposes. pdfChip generates print data from HTML, for example for web-to-print orders.
Label and packaging: spot colours, dielines, technical lines and white ink bring their own requirements. pdfToolbox detects and separates dielines, checks colour spaces and prepares data for downstream processing. For automated export out of InDesign, axaio MadeToPrint comes in on top.
Sign and display: print-and-cut workflows, cutting marks, nesting and oversized formats. pdfToolbox 17 adds a check that detects available space inside a document for markers and identifiers.
Archival and accessibility: pdfaPilot creates and validates PDF/A for long-term archiving. For accessibility, pdfToolbox checks against PDF/UA and shows where a document falls short. The tagging itself happens in the layout, and axaio MadeToTag is the tool for that. Relevant for everyone covered by the European Accessibility Act since June 2025.
Enterprise PDF processing: high volumes coming out of ERP, CRM or output management systems. pdfaPilot normalises and archives, pdfChip generates documents from HTML templates such as invoices, policies or mass mailings.
If you are unsure which combination fits your volume, talk to us. A short conversation usually settles it.
What does callas pdfToolbox cost
callas pdfToolbox has no flat-rate pricing. Licensing is modular and depends on:
- Which products are in your setup (pdfToolbox, Server, CLI, pdfChip, pdfaPilot, License Server, Dispatcher)
- Number of concurrent instances and server processes
- Processing volume (time- or process-optimized license models)
- Deployment environment (on-premise, cloud, Docker, OEM)
