Right! Finally got this sorted! There is no mention of there being a problem with pressed metal plates having raised letters on the DVLA site so the officer was just trying to give me a ticket,But for anyone that has or gets pressed metal plates there are conditions they must meet!
First and foremost they must be standard colours (white/yellow with black letters)
Second they must be Charles Wright font, be the correct size and spacing,
Thirdly they need the company's name and postcode that made the plates,
Fourthly they MUST have this BSA 145 AUD number printed on them, (this signifies that they meet the british standards association's tests for reflectivity etc so they can be used for road use,
They also must be the normal size and carry the normal rules for plates aswell, so if it is missing any of those listed above they aren't legal!
Luckily mine have all of those so please check before buying
if your's meet all of those and an officer tries to give you a ticket do not take an attitude with him, just explain that it meets those, and that they are perferctly legal for road use,
if it does go further I would advise to take up a case against the points and fine, but again only if it meets all of those rules and saying some guy on CS told you will not suffice sadly so please have a read around yourself to confirm all of this before putting the plates on the car!
That is all
