Multi-stage math
See source, export, and display cell pitch as separate values instead of one unexplained score.

Open Manga Screentone Tools Free browser toolManga Screentone Checker
Inspect a local manga tone raster at true 100% pixel scale, estimate its horizontal and vertical repeat periods, and compare it with a clearly labeled resize simulation.
Open Manga Screentone Checker Free browser toolHalftone Preview
Generate a reproducible manga halftone from explicit DPI, LPI, density, angle, physical size, and dot-shape controls, then export SVG, PNG, or JSON locally.

Every result is labeled simulated and explicitly excludes unknown press and device behavior.
Screentone Moire Checker FAQ
Production answers without the guesswork
Is the risk score a detected defect?+
No. It is a deterministic sampling score derived only from the entered values and is labeled as simulated.
Why does display scale matter?+
A browser or app can resample an already exported repeating raster, producing a preview that differs from its 100% pixels.
Does a lower score guarantee clean printing?+
No. Printer screening, RIP settings, paper, and physical output are outside the browser model.
