Paperless office-2

Today we continue our discussion on paperless office which is most important part out topic. Each of the technologies uses software that converts the raster formats (bitmaps) into other forms depending on need. Generally, they involve some form of image compression technology that produces smaller raster images or the use of optical character recognition (OCR) to convert the document to text. A combination of OCR and raster is used to enable search ability while maintaining the original form of the document.

An issue faced by those wishing to take the paperless philosophy to the limit has been copyright laws. These laws restrict the transfer of documents protected by copyright from one medium to another, such as converting books to electronic format. An important step in the paper-to-digital conversion is the need to label and catalog the scanned documents. Such labeling allows the scanned documents to be searched. Some technologies have been developed to do this, but generally involves either human cataloging or automated indexing on the OCR document.

However, scanners and software continue to improve, with small, portable scanners that are able to scan doubled-sided A4 documents at around 30-35ppm to a raster format (typically TIFF fax 4 or PDF).
