Each pixel in the raster image files on your computer (PSD, JPEG, TIFF) usually have 255 levels (8 bits) of Red, Green, and Blue information. Your monitor can display each of these levels and mix the RGB data to display many different colours. Inkjet printers can only print a dot or not print a dot. Therefore it has to perform some tricks to make the eye and brain think they are seeing continuous tones. The trick is called half-toning. We print small dots so that the eye sees an intermediate tone. There are two types of screening. Conventional screens (AM) use equally spaced dots and vary the size of the dots. Stochastic (FM) screens used in ink jet printers use a constant size dot and vary the space between the dots. The websites listed below explain more about how we screen from continuous tone images to half-tone images.

Automatic splitting of the target files for best fit on the specified number of discs
Several deinterlace filter presets
Audio AC3 and PCM passthrough
Audio MP3 encoding
Audio volume maximizing and/or range compression
OGG/Vorbis support, quality and bitrate based, adjusting the optimal video bitrate after audio transcoding in quality mode
