I experienced my first test pattern sometime in Germany in the 1980s. It was a television test pattern –still in black & white at the time. The tube television was the only electronic imaging device in our household. Picture and channel settings were regulated using dial knobs only. The analogue test pattern was used to facilitate the picture settings and to check for errors. It was broadcast for a few minutes just after the transmission sign off and just before the sign on. Much later, a different, more minimal test pattern reminiscent of early computer graphics would help me calibrate a monochrome ink jet printer.
