Pressing plant for Capitol Records, Inc., located in Jacksonville, Illinois. Manufacturing operations began on July 12, 1965, and continued up until 2004, at which time the plant ceased production of recorded media and became a dedicated distribution center for CDs and DVDs until 2013.

Capitol ceased vinyl pressing operations at Jacksonville in 1986 when pressing equipment was removed and CD manufacturing equipment installed. CDs began flowing from Jacksonville in early 1987, followed by DVD manufacturing, which continued until 2004.

The identifiable runout marking is a "0", either stamped or hand-etched and should be entered as such. Although it does sometimes look like an "O" or "o", do not confuse this pressing mark with non-Capitol discs that are stamped with an "o" (see Customatrix) or with a capital "O" (e.g., Epic or others). Jacksonville pressings can also be identified by the 1 1/2" (1.5" or 38.1 mm) diameter pressing ring in the label area.

Additional and complementary identifiers for Warner Bros. releases that were pressed by Capitol had the following codes on the lacquer numbers (the "W" in the 2nd position stands for "Warner"):
- Capital J for Jacksonville plant.
- JW for Jacksonville plant.
- WW for Capitol Records Pressing Plant, Winchester.
- LW for Capitol Records Pressing Plant, Los Angeles (Not to be confused with Longwear Plating's "LW").
