Key Features of d’accord

Display of visual differences in graphics and text

d’accord performs a visual comparison that shows you all the noticeable differences in graphics and text. The comparison is independent of the technical structure of the PDF, but refers only to the appearance, as it would be seen by a human viewer. Therefore, it does not matter if, for example, fonts are compared with paths or if the PDF has been changed by preflighting tools or PDF editors. For digital comparison, the PDFs are first rendered as a raster image using Adobe® PDF Library ™ and then compared using image processing algorithms.

Comparison of shifted PDFs with non-aligned positions

With d’accord you can also compare PDF files whose positions are not constant - that is, PDFs that are shifted against each other. Initially, d’accord automatically determines the alignment of the PDFs with each other and precisely overlays the corresponding pages before the comparison.

Automatic search for forms on the printing sheet

A particular highlight of d’accord is the ability to compare multiple forms against entire printing sheet: d’accord finds position, rotation and repeats of one or more forms on the printing sheet. This works for simple imposition patterns (such as leaflets) as well as for complicated gang forms that you have created using step & repeat software (e.g. for folding cartons).

Multi-page PDF documents and series of PDFs

Of course you can also compare multi-page PDF documents with d’accord and jobs with several PDF files such as several printing sheets including perfecting.

Grouping of differences with adjustable tolerances

d’accord does not simply show you the deviations as a (possibly large format) difference image. For an optimal overview, d’accord groups adjacent pixels into larger shapes that you can review in different graphical views. A list view also allows you to step through all differences step by step so that no location can be overlooked by mistake. If desired, you can check off and comment on differences. In order to display only deviations that are relevant for you, you can adjust d’accord with tolerance parameters to your requirements.

Proof report

You want to archive the results of d’accord to document your quality assurance? Or you would like to present the modifications between initial artwork and press-ready PDF to your client as an attachment to the form proof? Then you can use d’accord to create a clear PDF proof report with all the differences highlighted and annotated with your comments. Based on this report, your customers or colleagues will immediately find the relevant places on the form-proof that should be examined more carefully at the time of acceptance.

Freeform transform of PDFs

For the localization of individual forms on the printing sheet, the individual forms must first be properly cropped from the background. d’accord supports you with a variety of special features that facilitate the freeform transform. Especially for package printing, d’accord can automatically crop your form if you have a punching contour in a spot color or on a separate PDF layer. Simple forms can also be cropped by a predefined PDF box.

PDF comparison d'accord: Automation and Workflow Integration


You want to integrate d’accord into your workflow or access it from other software systems? Through the CLI interface, the d’accord Workflow version allows operation as a command line program. So you can easily integrate the powerful PDF comparison into every imaginable automation solution.

Even without an existing workflow system, automation is possible: You can also use d’accord workflow with a hotfolder technique. In this way, you can create proof jobs at several workstations that are managed by a central queue. For larger file volumes, it is even possible to achieve scalable performance by running the queue concurrently on several d’accord servers.

Safe from the beginning

Distinguish right from wrong changes.

It is often a long way from the customer’s artwork to the press-ready sheet. The submitted file goes through a chain of automatic and manual processing steps in the prepress. Do you ask yourself how to make sure that all intended changes exist and at the same time no unintentional differences remain undetected? d’accord helps you to detect both types of changes reliably and efficiently. So, you can verify at a glance whether everything is in order.

Digital precision.

d’accord performs an accurate image-based comparison between sheet and items. The use of digital data guarantees high precision results and an always consistent “attention”. The comparison works for all languages and fonts.
