Universal Manufacturing & Logistics Ltd. CD and DVD manufacturing company and plant located in Blackburn, Lancs., UK. Operating under this name from April 1999 to April 2002. Previous name: . Sold to: and renamed to Disctronics Blackburn Limited (effective May 1, 2002). This plant is often directly credited on the releases (CD mould text). The Blackburn plant can also be identified by a Mould SID Code IFPI 04xx in the CD mould (but that shouldn't be used to credit the plant). It is possible that pre-UML pressings still carry Made in the U.K. by PDO or by PMDC identifiers because the original glass masters were simply re-used. In this case add: Glass Mastered At - PDO, UK (or PMDC, UK respectively) and Made By - Universal M & L, UK. It is also possible that post-UML pressings/reissues carry UML identifiers because the glass masters were simply re-used by the new owners. The 4 x Universal logo in the outer hub was introduced by Universal Music Group in 2004 to signify CDs manufactured for the Universal Music labels and companies.
