Rorschach's mask (which he refers to as his "face") consisted of a specialized fabric, one that was actually two layers of fabric with viscous black and white fluids trapped between them. The fluids remained in constant motion, being affected by heat and pressure, however, the black and white colors never combined to form gray. The patterns formed by the fluids also maintained a consistent symmetrical pattern down the mid-line of whatever shape the fabric had been formed into.
Kovacs first discovered the fabric when he worked for a dressmaker. The fabric was originally made into a woman's dress and the marketing of such a product would be linked to Dr. Manhattan. The product's first customer was a woman named Kitty Genovese, who was unhappy with the dress, calling it "ugly" and refused to buy it. Kovacs thought differently however, and took possession of the fabric for himself, saying it was "very beautiful." At home he used heated instruments to shape the fabric into a full head covering, a face he "could look at in the mirror."
In a way it is true that this is his "real face" as the fluids react to his expressions, where without it, he usually never shows any facial expression, except anger or indifference.
Rorschach appears in the comic series Doomsday Clock (November 2017 – December 2019). This series will conclude the story of DC Rebirth. His mask appears on the lenticular cover of Issue #1, transforming into the symbols of DC's Trinity.
In the 2019 HBO series Watchmen, a far-right terrorist group known as Seventh Kavalry, inspired by Rorschach's journal, appropriated his mask to main their identity and followed a misinterpretation of his writings into creating a racially-based crusade against various law enforcement agencies and the Redford administration, whom they deem traitorous for their apologetic disposition towards African-Americans and other minority groups within the United States.
