Why Resolution matters

Pixel dimensions, DPI metadata, laser spot size, scan interval, and material response are related but distinct forms of resolution.

Practical check

How to evaluate it

Write down pixel dimensions, physical dimensions, and scan interval separately. Calling all three values resolution can hide which part of the workflow actually changed.

Go deeper

Learn the DPI and line interval relationship, calculate output pixels, avoid overlapping scan lines, and preserve exact size in a photo workflow.

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.
