Blue Ink Calligraphy Brush Lettering QR Code for Posters

About this design

Bold navy blue brush characters in a katakana and kanji style fill the canvas against a clean white background. Three square frames painted in tan brown strokes, each holding a small calligraphic glyph, disguise the finder squares. The blue strokes carry the dark modules, while the open white space between them forms the light ones. Strong contrast between deep ink and pale ground keeps the pattern clear, and a sweeping curved tail at the bottom finishes the composition.
