subtractive process การใช้

• But in a subtractive process, you don't, and we didn't.
• Like other CAD / CAM fields, CAD / CAM dentistry uses subtractive processes ( such as 3D models.
• There were other subtractive processes, including Gasparcolor, a single-strip 3-color system developed in 1933 by the Hungarian chemist Dr . Bela Gaspar.
• For example, printing, like mixing paints, is essentially a subtractive process, but halftoning can mimic an additive mixing ( as for light ).
• Before 1932, when three-strip Technicolor was introduced, commercialized subtractive processes used only two color components and could reproduce only a limited range of color.
• So the printer adds a fourth ink to produce black, and to render white it employs a color-subtractive process _ not printing anything at all.
• But the subtractive process had all but disappeared in the government until we restored it . " The National Security Council, strongly supported the New Look.
• Where colours are reproduced by a subtractive process such as in printing then it becomes more convenient to use a cyan-magenta-yellow ( CMY ) colour space.
• It could not yield multiple copies easily, special film was necessary to shoot with, and the additive image was colorful and clear, but inherently darker than subtractive processes.
• Alternatively, you could use a subtractive process where you start with a large lump of rock-salt and use a computer controlled hot water jet to selectively dissolve the crystal and thereby carve out the final shape you want.
• A reverse mask is then applied . ( Unlike a subtractive process mask, this mask exposes those parts of the substrate that will eventually become the traces . ) Additional copper is then plated onto the board in the unmasked areas; copper may be plated to any desired weight.
