A&E JUNE 2019 • a-e-mag.com 47 larger dots created for an exaggerated effect, use a number below 30. For either purpose, I like to use a round dot at a 45-degree angle, but those options are mostly subjective if the halftone is just going to be used as a design effect. In Figure I, there is no illusion occurring, as this image exhibits the larger, exaggerated halftone at 15 LPI. One added bonus: the color of a half- tone bitmap (black and white by default) can be changed with just one click in CorelDRAW. To do this, import a half- tone image into the CorelDRAW work- space (Ctrl+I). With the image selected, right-click any palette color to change the black areas of the bitmap. Left-click a palette color to change the white areas of the bitmap. Left-click the Transparent option (the "X" at the top of the palette) to make the white areas transparent (Figure J). One caveat: the file type must be a BMP file in order to perform this color modification technique. laser engraving / print fume extraction solutions call.
