Halftone

A tone-simulation method that varies the size, spacing, or arrangement of visible spots.

In the workflow

Why Halftone matters

Practical check

How to evaluate it

Judge the spot pattern at the final physical size and normal viewing distance. A halftone texture that looks attractive enlarged may dominate a small engraving.

Understand how one-bit dithering represents photo tones, how common algorithms differ, and how to choose without processing the image twice.

Prepare the pixels

Use the terminology in a real photo workflow.

Crop, tune, size, dither, and export a one-bit PNG on iPhone or iPad. Test the result on scrap with your machine and material guidance.
