Graintouch is a drawing app with the soul of print. Inspired by Risograph™ aesthetics, it lets you layer, blend, and create with the warmth of real ink—right on your screen.

BOOL BRUSH
A bold, organic vector brush that stacks colors like ink on paper. Blend, overlap, knockout and build rich textures with effortless strokes.

PRINT SIMULATION
See your artwork as if it just rolled off a risograph. Offset imperfections, layered tints, and the charm of real ink—without the mess.

MINIMAL UI
Nothing in your way, just pure drawing. A clean, focused space where tools feel like an extension of your hand.

COLORFUL CONSTRAINTS
A playful palette of 18 handpicked inks, straight from the riso universe. Instead of endless choice, you get meaningful constraints that spark creativity—just like mixing real inks on a print run.

VECTOR STENCILS
Every Layer becomes a crisp, resolution-independent stencil. Your drawings export as clean vector stencils, perfect for scaling, separating by color, and bringing straight to print—no loss, just pure shapes.
