As already posted.....no one listening it seems.....original plates have embossed registration numbers and words like 'sindh' etc. Only the official Govt seal is painted. On the older larger plates, the seal was embossed too.
Embossed characters mean if you run a hand over the plate, you can feel the content.
After market plates have simple painted characters. To my knowledge no one makes embossed plates as it is illegal.
Hope this helps.
