More examples


Applies a 1-bit black and white horizontal or vertical line screen to a continuous tone image. The result has cleaner, straighter lines than a conventional line screen and is more "technical" looking. If you need optimal gray level simulation take a look at the Classical Halftone plugin. This plugin needs high resolution images. Use it on images of at least 300 pixel per inch (ppi) resolution. (600 ppi are recommended). Optional you can set the pattern and background color and blend the result with the original image
