What are Captured Documents?
Captured documents are electronic, digital images of the information physically present in a paper document. They are converted into a format that is viewable on a computer. The file may contain images, or just textual matter. Whatever it be, the information on the file is captured and converted to a machine editable electronic file. Captured documents are often bulky and pose problems while archiving, emailing, uploading etc. Thus, it is necessary to compress captured documents -it can be a hindrance to business organizations working towards a goal of a paper-less office.
Types of Captured Documents and Their Compression Techniques
There are basically two types of captured documents based on the output of the scanner. One is the image file and the other is the PDF file. Compressing capture documents are essential, and depending on the nature of output, the compression algorithm differs. For a PDF file, one needs to decide which font and image to reduce and which to retain. One also has to decide whether he wants the file to be accessible through older versions of the software or not. For image files, you need to determine the type of image and then what you want to do with it. If the image is highly sensitive and needs to be preserved for a longer period of time, lossless compression of captured document is advisable, like TIFF, PackBits or LZW. These compressions will make sure you don't lose out much on data. Enlargement of data is also possible in this kind of compress captured document. For a PDF file with graphics or a logo, lossy compression methods like JPEG is what you should follow. This will reduce the size to almost 1/10th its original, but with substantial loss of data. One significant benefit of JPEG compressed captured documents is that you can choose the quality of the output.
Advantages of Compressed Captured Documents
Compressed captured documents are really small in their size. A compressor that can compress captured documents will not only reduce memory space, but will also speed up transferring rates. For computers with slow Internet connections, sharing large files across the Internet will be rendered fast. Accessing and archiving these files becomes easier too. Compressed captured documents in many ways have started influencing offices of large organizations that deal with tremendous amounts of paper work.
