Spanish CD, DVD and Blu-ray mastering, pressing and duplication plant in Rubí, Spain (near Barcelona), founded in 1999 with full legal name Duplico 2000, S.L..
They started in 2001 or 2002 with the manufacture of CDs and DVDs and added Blu-Ray manufacturing in October 2010.
Definitely closed in 2012 after bankruptcy.

When their logo appears in the matrix band, please credit them with Glass Mastered At in LCCN.
Sometimes their logo is omitted, in that case the matrix band design with SID codes can be used to identify Duplico 2000. If unsure, please ask in the forums.
CD manufactured via the Acdpress subsidiary sometimes replaced the Duplico 2000 logo with their own.

Known Mastering SID codes, they have no IFPI prefix: LN76, LN77, LN78

Since September/October 2004 a sequential number was added to their matrix band, but it was assigned internally even before it appeared in the Matrix. (example: Christina Rosenvinge - Grandes Exitos [92»98]: Alguien Que Cuide De Mí)
When the sequential number appears in the matrix band, it can be added to LCCN.
The sequential number is 5-6 digits long and has it's own dedicated field in the matrix.

The matrix band pattern is:
[Duplico 2000 logo - when present] [Mastering SID Code] [Sequential number - when present] [Release specific data] [Glass master date]

Examples:
Various - Made In Barcelona (Indie Rock All Stars Compilation)
Ktarsis - Diseñando El Alma
Various - [Crib Sessions] (CD with Acdpress subsidiary branding)
Axenstar - Far From Heaven (CD with no sequential number)

Note:
Represses retaining the original sequential number and identical packaging do not generate unique releases on their own.
