Laser printing on security seals: the pros and cons

Security seals are a safe way for businesses and individuals to store information about a parcel, box, package or container, without the item inside being compromised. The identification of the item contained within can be revealed through the use of universal identifiers and markers such as barcodes, QR codes and coded numbering systems.

What is laser printing on security seals?

The process of laser printing onto a security seal involves the embedding of information directly into an item so that it is contained within it. The laser will penetrate the material such as plastic, glass or metal, for example, and ensure that the information cannot be tampered with or altered in any way. The information is transmitted via a laser beam usually controlled by a computer which stores the information to be transferred.

So what are the pros of laser printing?

The main and most obvious advantage is that it is a permanent and indestructible marking which will not degrade easily when the security seal is exposed to water, chemicals, oils or corrosive substances and so these seals are ideal for transportation in penetrable or hazardous containers.

Another advantage is security. Due to the permanent and indelible nature of the marking, it is very difficult to alter or tamper with the marking without being spotted easily, and as such, it is classed as high security marking.

Another advantage is the speed and efficiency by which laser printing can be undertaken at a very reasonable cost. The technology is also highly versatile and can be used on a variety of surfaces and materials in different temperatures with differing humidities. The amount of data which can be stored within the coding systems can also be huge, and this is highly effective where space may be limited.

Are there any cons?

There truly aren’t many cons when compared with other forms of printing, only that laser printing can only work on specific coloured backgrounds and can only print one sided.
