The acrylic plate is usually extruded or injection moulded. Injection moulded plates are mass produced for the industry by a few large manufacturers and are cheaper. Extruded acrylic comes in sheet form and can be cut with a laser cutter, router, or other suitable cutter, into the specific sizes required for number plates.
Both types are of an equal quality and consistency, and the choice depends on the manufacturing capabilities of the number plate maker. Extruded acrylic is more expensive but can be cut to any size the maker wants. Injection moulded acrylic requires a large manufacturing operation to be cost-effective.
Once the acrylic blank has been obtained, it needs to be laminated with an optically clear adhesive that can pass the British standard. This means it must be able to work across a wide temperature range to avoid failure by melting or freezing. Laminators can apply adhesive in sheet form (for extruded acrylic) or in single plate form (for injection moulded acrylic).
Optically clear adhesive is usually a solvent based acrylic or polyurethane adhesive, such as 3M's VHB, a general purpose signmaker's adhesive with a wide range of applications. These adhesives are pressure sensitive (they bond through the use of pressure during application) and are particularly good at bonding with low surface energy materials such as acrylic.
Once the acrylic blank has been laminated, it is ready to be made in to a number plate.
The retroreflective film is a special reflective vinyl manufactured to meet the reflectivity and colour regulations of the British standard. It is cut to size using a vinyl cutter, laser cutter, die cutter, or other suitable cutter. The term "retroreflective" refers to a surface that reflects light directly back to its source, rather than reflecting it off at an angle. At night time, ANPR cameras shine infrared light at your number plate in order to read it. Without the light being reflected back to the camera lens, the camera would not be able to read your plate.
The registration number, supplier name & postcode, the British standard, and optional flags and borders are printed directly on the reflective sheet. The sheet is then lined up on a jig & roller with alignment pins, and the acrlic blank is placed on top of it (adhesive side down). Both components are then sent through a roller (can be hand-wound or electric) and pressed together, forming the finished number plate.

The size of the number plate does not matter, so long as the correct font, font size and character spacing is used. This means you can drive on public roads with shortened number plates providing they meet BS AU 145d.
More about BS AU 145d
Something to keep in mind is that even if shortened number plates meet the design specifications set out in BS AU 145d, the number plates will be illegal if the plates do not show the correct markings at the bottom.
Number plates have to have the following text at the bottom:
Legal optional design elements
The following optional number plate elements are legal, providing that they do not modify the design specifications required under BS AU 145d:
We specialise in the design and supply of 3D and 4D plates which we offer in a variety of different sizes. These sizes include:
It’s important to note that the shortest plates are only compatible with personalised registration numbers.
Also, there are design requirements as specified by BS AU 145d that limit the amount we can legally shorten number plates.
For example, number plates must leave 33mm of space between the identifier and 11mm between each character. When you combine this with a minimum font size you can see why it is only possible to shorten number plates so much.
Will my car pass its MOT with short plates?
There have been cases where cars have failed their MOT because of short number plates but ONLY in cases where the plates did not meet BS AU 145d.
MOT rules state that plates that meet BS AU 145d are legal for road use. The length of the number plates has no bearing on this so long as everything else (the font, font size and spacing of the characters) checks out to be fine.
Show plates and designer plates
Although show plates / designer plates are illegal to use on public roads, they can be used on private land and in car shows. Show plates can be even shorter and use different fonts to legal number plates, which must comply with BS AU 145d.
We supply show plates without legal writing and can cut these to any size and use any font and font size. We can also use non-standard spacing and colours. This opens up a new world of design opportunities, but we must reiterate that show plates are ILLEGAL to use on public roads and do not bear our manufacturer’s mark.
Conclusion
You can use shortened number plates on public roads without breaking the law. They are 100% legal so long as they meet BS AU 145d.
However, because plate legality is dependent on the plates meeting this standard, you should only buy from a registered number plate supplier. Registered number plate suppliers have a unique RNPS number to identify them.
]]>3D and 4D number plates are both evolutions of the standard number plate which was introduced in 2001. Standard number plates are made from acrylic using flat letters that are printed onto the plate by a machine.
You will find standard number plates on all new cars sold in the UK. They are cheap and quick to manufacture, allowing dealerships and suppliers to roll out massive batches in one go with very little new investment.
However, while the standardised nature of these number plates is good from a manufacturing sense for suppliers, it does make the design boring. Flat letters don’t stand out and the plates can’t be ‘different’.
3D and 4D plates are a 100% legal alternative to standard number plates. They both have one big difference over standard plates – raised characters, which bring depth to the plates and provide a more premium or upmarket appearance.
So, the difference between standard number plates and 3D and 4D plates is that 3D and 4D plates have raised letters and numbers.
But what’s the difference between 3D and 4D plates?
3D and 4D plates are both popular options for vehicle personalisation. 3D plates are more common, but only because the manufacturing process has been more widely adopted. Most number plate suppliers only do 3D plates (we do both).
The key difference between them is how they are made and how they look. 3D plates are easier and faster to make than 4D plates.
You can tell the difference between 3D and 4D plates by how raised the letters are and how they look. 4D characters are more raised and more rectangular. 3D characters are less raised and more rounded for an understated look.
3D plates
3D plates are made from acrylic with individual raised letters. The raised letters are manufactured from polyurethane and get ‘stuck’ to the acrylic plate by hand. An aligner bar is used to guarantee perfect spacing.
The rounded and shiny gel-like appearance of 3D plates makes them a great choice if you want to add understated personalisation to your vehicle.
4D plates
4D plates are also made from acrylic but instead of polyurethane characters, they use professionally laser cut characters made from acrylic sheet. This allows the characters to be thicker and more rectangular for a bolder look.
You can also get 4D gel characters which have a wet look. These are made in the same way as 3D letters but have a thicker profile.
The rectangular and more raised profile of 4D plates makes them a great choice for adding standout personalisation to your vehicle.
Which is best?
3D plates are more common than 4D number plates, so if you want to make your number plate truly individual, 4D plates have the advantage.
Both plates look better than standard number plates and are 100% legal so long as they meet BS AU 145d standards. The number plates we manufacture meet these standards and make a fantastic upgrade to any vehicle.
