The laws regarding the lettering and styles are as follows... we are only allowed to make LEGAL number plates and this is what we can make:
1) You can have Plain, 3D or Carbon lettering
2) You can have red, green, blue or black border
3) You can have GB, UK, England, Wales flag on the left
I also believe you are allowed a small amount of lettering at the bottom of the numberplate as my local motor factor is allowed to do all the above plus this and all the plates are legal.
You can also have "hi-line" lettering, but i think they look a bit poo TBH anyway.
i'm amazed they blamed the lubricant, maybe we do it differently, but the proccess of making number plates is simple, place down the reflective sheet, lay out the letters, then get a bit of plastic (nothing printed on it) spray the back to stop static, and then place that on top, run though some rollers a couple of times, job done.
the only liquid used it the stuff to stop the static electricity picking up the letters and moving them out of place (common on i/1's)
in future if this happens to anyone else, take them back but be really nice, ask for the manager then just say something like "hi there mate, look i bought these as my old ones were going to fail the mot, i took it in and it still failed because of your plates, do you think you could make another pair up for me?" then when he takes you to the desk, mention i cost you £40 quid to retake the mot and ask to see if they can use carbon lettering and a border/gb background, go full whack, generally they'll chuck you something as compensation.

... well our manager would anyway
