Meaning of Fimbriation in Urdu

In heraldry and vexillology, fimbriation is the placement of small stripes of colour (technically called "tincture" in this sense in heraldry) around common charges or ordinaries, usually in order for them to stand out from the background, or perhaps just because the designer felt it looked better, or for a more technical reason (in heraldry only) to avoid what would otherwise be a violation of the rule of tincture.
