Technically speaking, halftone screens are "tessallations" - patterns that encompass a surface past times the repeated role of a unmarried shape, without gaps or overlapping. And since tessallations are pop decorative items - I terminate upwards seeing halftone screens everywhere. Here are a few from a recent trip to Seattle.
Influenza A virus subtype H5N1 classic Diamond halftone dot
An illustration of a high lpi traditional Square dot halftone
In contrast to a real depression lpi Square dot
Waiting to cross the street I location a mix of 2 halftone patterns
At outset it appears to live a classic Round dot mixed amongst a to a greater extent than subtle Square dot halftone
But on closer exam it seems to live an exotic version of Esko's Concentric screening. Interestingly the pixels that brand upwards this sidewalk halftone are circular instead of the traditional foursquare shape.
Walking past times this edifice reveals a fine illustration of
Second guild FM/stochastic screening.
Sometimes the lastly halftone enshroud is non visible, simply instead, y'all tin post away come across the foundation for the halftone. Halftone enshroud dots are formed past times a "threshold" array - basically a designing made upwards of 256 shades of greyness which determines which pixels are turned on to shape the actual dot.
