creating security watermarks

We’re always saying that you’re never far from something in your everyday life that contains a chemically-etched precision part. Whether it’s your mobile phone, your car, your laptop or the machine that makes your morning coffee. What may not spring to mind is how it fits in to the security of your ID and your money at home or abroad. That’s where watermarks come in.

how does chemical etching fit?

Watermarked security paper can be applied in a wide range of industries but on a day-to-day basis, you can see it in the banknotes in your wallet and official documents like a certificate or your visa or passport. It helps prevent counterfeiting and prove legitimacy.

In the expert hands of our engineers, the chemical etching process can achieve the micro-scale precision and detail required for secure watermarks -something counterfeiters cannot reproduce. The electrotype watermarks we create are developed to be so precisely and intricately devised that they are almost impossible to imitate. They allow even the smallest of features and highlighted areas be incorporated into a bespoke design and appear lighter and brighter than the surroundings.

In a meticulous manufacturing process, our customers use the design we have co-developed to create the physical watermark itself during the papermaking phase, where a cylinder featuring the pattern is pressed onto the wet paper pulp which passes between two rolls. This pressure alters the paper’s thickness and density in specific places, creating an embedded design or pattern that is visible when the paper is held up to light.

Chemical etching produces high definition components that are burr-free – an essential aspect to producing a cleanly defined image. Additionally, the ability to manufacture in specialist alloys allows for easy matching to complement our customers’ manufacturing processes.

One of the key advantages of electrotype watermarks is their durability. Unlike traditional watermarks, which can be easily removed or altered, electrotype watermarks are resistant to tampering. This makes them highly reliable for ensuring the authenticity and integrity of documents such as banknotes, passports, and certificates.

In addition, complex designs and patterns create an appealing visual effect, enhancing the overall aesthetic value of the document produced.


Electrotype watermarks are a key way to authenticate and verify currency and documents and cannot be easily reproduced.

Not only are they durable and long-lasting, but their design intricacy and uniqueness make them not only attractive but also extremely complex to replicate and impossible to photocopy, offering a robust defence against tampering and forgery.
