LuraDocument PDF Compressor with professional electronic signature
The LuraDocument PDF Compressor is available immediately with a professional electronic signature from the Swiss company OPENLiMiT SignCubes AG. Highly-compressed PDF or PDF/A files can be signed electronically and stored in a way that meets legal requirements, using just one tool and in a single step. That's what the software from OPENLiMiT does. It has been certified by the Federal Office for Security and Information Technology (BSI) in accordance with the international IT security standard, Common Criteria EAL 4+, and approved based on the German Digital Signature Law.
Another advantage of this product integration is that entire batches of documents can be signed in a single step. The user only needs a chip card for his personal signature and a card reader.
The standard version of the PDF Compressor Medium comes complete with OPENLiMiT Batch Technology for batch signatures. The PDF Compressor in the server version has this as an optional component. In addition, in the server version, the license acquired with the signature is independent of the number of signed documents (unlimited), as for example also in the OCR technology.
Improved image quality
The newest version of PDF Compressor Server now maintains the quality of embedded images (photograph, logo, and graphics). The old version PDF Compressor Server applied MRC (Mixed Raster Content) Compression across the entire scanned document, including across images embedded on the scanned page. In doing so, it would attempt to separate text components from background colors into different layers to maximize compression. However, in doing so, embedded images would also be segmented creating damaging visible artifacts. The new PDF Compressor Server can identify the location of embedded images and preserve them prior to the MRC compression, thus maintaining the original look and feel of those images. Now digitized newspapers, journals and magazines can benefit greatly with MRC compression without foregoing the visual quality of their embedded photographs, logos and graphics.
Less storage space needed for PDF/A files - improved compression rate
We're happy to report that once again we have been able to improve the average compression rate for PDF/A files by 10-15%. You notice this benefit because the scanned and compressed documents are now even smaller and require less storage space. Specifically, this means that the files can be more quickly opened and downloaded from the archive, and also sent more quickly as email attachments.
As a reminder: LuraDocument can be used to reduce full-color documents to the size of a TIFF G4 file. And with black & white scanned documents, the file size of the output format in TIFF G4 is considerably smaller. Finally, this procedure makes highly-compressed, standardized PDF/A files considerably smaller than the original files. Such a result can be achieved only with compression procedures that use proprietary formats. If the newly optimized procedure is used, the compressed PDF/A file can be reduced again by another 10-15%.
