1.3 User Environment

1.3.1 Limitations(PDF Encrvyption)

Applications Required to View or Change Permissions of Encrypted PDF
Any PDF file that is generated by an iR device to which the Kit has been installed is prepared in keeping
with general PDF specifications. Not all viewer applications, however, support particular specifications
used by the iR device, not permitting browsing of the file. Furthermore, a viewer may not permit viewing
of PDF files of specific versions. An encryption PDF file is in keeping with the requirements of version
1.3 if its level of encryption is set to 40-bit RC4, while it is compatible with the requirements of version
1.4 if set to 128-bit RC4. (If not intended for transmission in encryption PDF, the PDF version will be 1.3.)
In a practical situation, a viewer will not be able to open a PDF file encrypted to 128-bit RC4 unless it
supports the applicable specifications whether or not it is designed to support encryption PDF in general.
EX:
Acrobat 4.0 supports up to 40-bit RC4, and thus is not capable of opening a PDF file encrypted to 128-bit
RC4, which requires Acrobat 5.0 or later. Third party applications call for specifications of their own, and
there is no guarantee that they will operate normally.
Attention:
If it is only encryption PDF inspection, even only Adobe Reader (It was Acrobat Reader ) is possible
inspection. When the authority option is changed, it is necessary to note it because Acrobat is needed.
Because the application made of 3rd Party must depend on the specification on the application side,
operation is unwarrantable.

1.3.2 Limitations(Serchable)

Use of Text in a Searchable PDF File
If the PDF viewer possesses a text search function, a search may be run within the transparent text in the
file. If the application is equipped with a PDF editing function (as is Adobe Acrobat), transparent text may
also be copied for pasting in a different application or turned into a text file. If Widows NT4.0/2000/XP/
Server 2003 is used, turning on the operating system's index service and installing the Adobe PDF Filter
will enable running of a search in the entire text of a PDF file.
