How dots reproduce tones
A halftone screen turns a continuous tone into a pattern that a printing process can reproduce. The apparent darkness comes from how much inked area the pattern occupies and how the dots are arranged.
The print context
Halftone printing: dots, screens, and practical limits
A browser preview can show the character of a halftone. Commercial printing adds paper, ink, screen, resolution, and registration constraints. Understanding the difference helps you hand off a design with better questions.
The useful part
LPI is context, not a universal preset
Line screen frequency is chosen with the process, paper, ink, and viewing distance in mind. A decorative SVG or PNG from this site is not a substitute for the printer’s preflight settings. Ask the printer which color space, resolution, screen angle, and trapping rules apply to the job.
The useful part
Digital effect versus print preparation
Use HalftoneDots to explore an aesthetic and create editable artwork. Before production, check the output with the people and equipment that will actually print it.
