Japanese Brush Calligraphy Ink QR Code for Posters

About this design

Bold dark brown brush strokes and scattered kana-like glyphs drift across a pale cream ground, touched with red ink splashes. Three round red seal stamps with ring borders disguise the finder squares, while the thick calligraphic strokes and small black glyphs carry the dark modules. The light paper space between characters supplies the light modules, and the heavy brown against cream gives strong contrast. A small red cartouche stamp near the lower left adds a traditional signature touch.
