List to help make it easier to identify vinyl pressing plants based on the matrix numbers in runouts.

    "yy" is the year of the pressing, while "xxx" is the sequence number

  2. Cascade Record Pressing

    “CP## - ####”: First two digits after "CP" denote the manufacturing year. Followed by a 4 digit number.

    Please note that sometimes there will be a "-" between "CP" and the first two digits.

    CP16-0341 - Lunaria
    CP-17-0202 - Echoes Of The First Dreamer (The Musical Prequel To Golem)
    CP18-0223 - Stardew Valley Complete OST

  3. Celebrate Records GmbH

    After the 5 digit numeral code, the 2 digit disc numbering (ZZ) can be found, which starts at "01".
    On multi disc releases the last digit usually incrementally rises by 1 for each disc. (Example: Disc 1 = 01, Disc 2 = 02, etc.)

  13. Precision Record Pressing


    Please note that runouts from this plant also includes GZ Media runouts.
    Generally it's safe to say that black vinyl records (and some single colored) are pressed at Precision, while more complex color patterns are likely still pressed at GZ Media.

    In cases where it's clear or suspected that the pressing was done at Precision, add Precision as "Pressed By" and GZ Media as "Mastered By".
    In cases where it's clear or suspected that the pressing was done at GZ Media, add Precision as "Manufactured By" and GZ Media as "Pressed By"
