The stamp is an example of security paper printed on one side and gummed on the other side, which when applied on postal products is proof of the payment in advance for post services . Normally, security features applied are: watermarks, visible and invisible fibres, superficial fluorescent treatment and the classical glue coating which allows the stamp to stick to the postal product.
Likewise, admission to paid shows and special events is possible thanks to value security paper, which ensures the non-reproducibility of the ticket and hence impossibility to counterfeit the original one. These tickets are equipped with security elements like watermarks, visible and invisible fibres, screen-printing and holographic bands,surface treatments , etc.
The bank cheque has rightfully replaced paper-money and for this reason many ' grades' of security features are applied. In addition to the watermark, visible and invisible fibres, corianders and sensitisations are inserted in order to prevent the counterfeiting of the support feature. Moreover, paper used in the manufacturing of bank-cheques is normally treated in order to allow its customisation by the various banks thanks to the use of ink-jet or laser printers.
The passport is definitely the most important personal identity document, as it permits the holder to be identified all over the world and to request a temporary or permanent authorisation to move about or stay in a foreign country. It represents one of the value security papers bearing the highest security-standards, 'equipped' with visible and invisible fibres, watermarks and security-threads: its pages are sensitised towards highlighting any counterfeiting and are treated superficially in order to allow competent authorities to customise the first pages of the document.
The object of watermarks in paper is, essentialy, identifying the paper, as a signature of the manufacturer, or as a security measure to avoid forgery of important documents such as bank notes, invoices, passports, entry tickets, etc.
Watermarks in the past have generally been reserved for large corporations with large budget.
Make a distinctive impression with your own watermarked papers.
Watermarks are designs or patterns put into the paper when it is made, by making thinner (line or wire watermarks) or thicker (shadow watermarks) adjustments to the layer of pulp when it is wet.
You can opt to either a) buy an existing watermark paper off-the-shelf or b) choose to have your own logo, text, coat of arms, etc. as a bespoke watermark. For the custom watermark, this involves one of two processes 1) for smaller quantities (e.g. 2,000+ A4) we can produce your watermark paper using our patented process that can have your watermark paper ready to despatch within 7 to 10 days, or for more substantial orders (200,000 A4 sheets plus) we can get a custom dandy roller made at the mill, this works out more cost effective for higher volumes, however the lead time for this is in weeks, rather than days.
Copyright protection of digital contents, as one of the most important application of digital watermark, works by watermark verification. In traditional watermark authentication scheme, a prover exposed a watermark to be present in a digital data to the possible dishonest verifier. However, a potential attacker is able to spoil or remove the watermark entirely once classified information like the watermark or the embedding key is known. Some of previous schemes proposed as solution haven’t achieved desirable result really. Their lacking of security and validity is the most serious problem. In this paper, we propose a secure watermark verification scheme based on zero knowledge protocols and public-key encryption scheme in order to solve this problem. There no secret information that can be used for removing watermark is disclosed during the verification process. It has considerable advantages over previously proposed schemes in terms of security and validity. 1.
This brighter paper has made it more difficult to view the artificial watermark.For this reason, many security paper manufacturers have added a slight amount of color to the artificial watermark.

The banknote is the most complex and prestigious value security paper from the technological viewpoint. It is manufactured using pure cotton-fibres paper, which makes it particularly 'robust' and more resistant towards wear and tear as compared to common paper. The many security elements which a banknote could have, may either be inserted, manufactured or applied during the whole production process. Pigments and fibres, watermarks, security threads, holograms, screen printings as well as superficial treatments coexist in one single product which apparently looks simple like standard paper.
