The DeviceLink Add-on consists of a number of DeviceLink profiles and is a payable option for pdfToolbox Server 4.

are a special form of ICC profiles, which offer a color transformation from source to destination in ONE profile. This way, each color of the source color space is directly transformed to a certain color in the destination color space. Device Link profiles are certified by the ICC (International Color Consortium).

callas DeviceLink Add-on Server is delivered with a package of the most common DeviceLink profiles but also offers the possibility to install your own.

Please find a list of profiles here.

DeviceLink profiles complement the usage of regular ICC profiles to avoid weaknesses of a color conversion based on ICC profiles for certain tasks. These weaknesses mainly are the CMYK to CMYK transformation and e.g. the preservation of pure black text in a picture.

A CMYK to CMYK transformation with ICC profiles always is performed via the device independent Lab color space, which leads to a complete reseparation of the data with partly unpredictable and unwanted results. This does not happen with DeviceLink profiles, which offer a direct control of color composition.
