WHAT IS 8 BIT? What is 8 Bit? - Binary Logic • Bit is short for “BInary digiT” • A bit is the smallest piece of information that a digital computer can address. • A bit is a switch that is recognized simply as being on or off, and is recognized by the numbers 1 and 0. • Colors on a B&W digital copier must be encoded using bits, with one bit representing two colors, usually black and white. • An eight bit depth designation on a B&W digital scanner indicates that each scanner dot is represented by 8 switches that simply turn on or off. Because of the possible combinations of eight switches, each dot can be any one of 256 shades of gray. Therefore, 8 Bit is 2 to the 8th power. The equation is simple and is calculated as follows: 8 Bit = 2x2x2x2x2x2x2x2=256 4 Bit = 2x2x2x2 = 16 2 Bit = 2x2 = 4
WHAT IS 8 BIT? Digital Concepts - Binary Logic • Now consider that each dot is being evaluated for color. At 8 bits of possible value per color for each of the Red, Green, Blue scans, the total number of possibilities jumps to: 256 X 256 X 256 = 16.8 Million possible combinations of colors. That’s a big box of crayons!
WHAT IS 8 BIT? “What Is More Important? The Size of the Dot…. Or What Goes In It?”
WHAT ABOUT COMPETITORS? In contrast, here is a sample list of competitive vendors, and their video interface specifications: • Xerox = Advertises 2400dpi, but is a 600dpi pixel, divided into 4 quadrants, to simulate 8 bits per pixel • Canon = 4 bits per pixel • Sharp = 4 bits per pixel • Ricoh = 2 or 4 bits per pixel selectable. When selecting the High Quality (4 bit) mode, causes laser engine to draw image twice, causing slow print speed
WHAT ABOUT COMPETITORS? Since the Computer Sends 8 Bit… Shouldn’t Your MFP Be Able To Print It?
8 Bits Per Pixel Sample “Tie Downs” • “Since the bizhub provides you with 16.8 million colors to choose from, won’t your staff benefit from this state-of-the-art color output?” • “Can you see how your company’s marketing will improve its ROI?” • “Wouldn’t you agree that the size of the dot, is not as important as what goes in it?” • “Can your staff wait to put Konica Minolta’s innovation to work in your office?”
