Red and Black Ink Calligraphy QR Code for Posters

About this design

Bold black brush strokes swirl across a white ground, surrounded by small scattered characters and flicks of red ink. Three red square frames, each holding a tiny red seal-like glyph inside a white ring, disguise the finder squares. The dense black calligraphy loops and character clusters carry the modules against the clean white background. Strong black and white contrast keeps the pattern clear, and the red accents bring a seal-stamp feel to the composition.
