Speaking on her spotlight panel at WonderCon in San Francisco, the artist said that the much anticipated series had been pushed back for promotional reasons.
It will be released at a time when there are no major events that will overshadow the debut.
Fans will not see Reeder's interiors for the title until February 2012, as she is illustrating the second arc. The first will be provided by J.H, Williams III, who illustrated the Batwoman-starring Detective Comics run and is penning the new series alongside W. Haden Blackman.
Reeder said that Batwoman was the most exciting project she is working on at the moment.
The title has been subject to a string of delays since its announcement last year.
The character made an appearance in Grant Morrison's Batman Inc. #4 last month alongside original Batwoman Kathy Kane.
