Areas of use

Web & Mail

Web-based applications demand short response times. Potential customers lose interest when online publications and documents are slow to load.

Same as poorly compressed PDF documents make emails unnecessarily large and can slow down communications or prevent the exchange of documents by email altogether.

Small and linearized PDF documents reduce response times significantly and improve the outgoing mail processes significantly.

Pre-press stage

The priorities in the pre-press stage focus on correct reproduction and color quantity reduction during printing. Hence, all colors can be converted to CMYK for instance.


Archiving requirements can vary. For instance, alternative images may be required in one case but not in another. Redundant or unnecessary data should not be archived in either scenario. The 3‑Heights™ PDF Optimizer component offers selective optimization options to enable precisely these kinds of configuration variations.
