What is PDMark technology?
PDMark® - Paper Data Mark is a unique patented technology of writing digital data onto paper. PDMark technology was developed with the aim to bring possibilities and advantages of working with electronic documents into the world of paper documents. The ability to store digital data directly onto paper bridges the gap between the paper and electronic worlds.
Where can be PDMark technology used? Who is the target group?
PDMark technology can be used anywhere, where paper documents are to be electronically processed, and where its main attributes can be utilized, i.e. document’s contents protection and improving the efficiency if its processing. PDMark technology has made its way to government agencies as well as to the private sector. You will find examples of application in the section Applications of the technology.
Which technical equipment do I need to be able to use PDMark technology?
PDMark technology does not pose any special requirements for technical equipment. Common office equipment is sufficient: a printer (laser or inkjet) with 600 dpi resolution and a common scanner with 200 dpi resolution.
How does PDMark technology store data on paper?
Data is written into the background of the document, either over the whole area of the document or into a reserved region as needed. The document’s background formed by PDMark symbols can be overlaid with text or an image. Besides that, PDMark technology can produce images in the PDMark background in eight degrees of grey. In the background of the document, PDMark symbols can form graphics in watermark style without disturbing the substantial printed text.
Is a document produced with PDMark technology any different from a standard printed document?
A document produced with PDMark technology only differs from a standard document in the fine grey background formed by tiny PDMark symbols.
What kind of data can I store using the PDMark technology? What is the capacity of one A4 page?
PDMark technology can be used to store any data in an electronic form on paper. The capacity of one sheet of A4/Letter size is approximately 40kB. This represents around ten pages of text in .doc format.
What should I do if my PDMark document is damaged or I have just a copy of the original?
PDMark technology is also able to recover the original stored content from a substantially damaged document. The ability to recover the original texts depends on the extent of the damage of the original and the amount of data stored on one sheet of paper. The bigger the amount of data is the bigger the portion of the original sheet needed to recover the data. PDMark technology can successfully cope with damage like a document that has been scribbled over, stained document, physically incomplete document with a portion torn off, and soaked and dried up document.
PDMark technology can also read data from a copy. However the copy must of good quality.
