PDF - intelligent High-Quality Compression
In Readiris you also have the possibility to compress your PDF documents. Refer to the separate section
Compressing PDF documents for more information.
Tip: also see the section Password-protecting PDF documents and Digitally signing PDF
documents.
Compressing PDF documents
The PDF documents you generate with Readiris can be hyper-compressed by means of iHQC. iHQC stands
for intelligent High-Quality Compression, I.R.I.S.' proprietary, efficient compression technology. iHQC
is to images what MP3 is to music and what DivX is to movies.
To generate compressed PDF documents:
 Select PDF in the Output group, and then click the down arrow beneath it to configure the settings.
Or if PDF is not displayed in the Output group, click Other.
 Select the required PDF type from the drop-down list.
Note that iHQC compression is unavailable for PDF Text and PDF Text-Image files.
 Select the required compression level: there are three levels of compression.
For each level there are two types of compression: Good Size and Good Quality. Good Size offers
the best compression, with a minimal loss of image quality. Good Quality offers slightly larger output
files with better image quality.
Notes:
In Readiris Pro you can select Level I - Good Size, and Level I - Good Quality.
In Readiris Corporate you have access to all levels of iHQC.
