*1: Since focusing in yellow is hardly readable, yellow is mixed with cyan for more
readability, resulting in green.
*2: Each portion of colors has three different magnitude of halftones (bands). If focus
is excessively lost, dots are not recognizable with the 16/256 band, resulting in
uneven density. It also results in vertical streaks in the 24/256 and/or 32/256
bands.
