Machines have memories; like stairs worn hollow by footsteps – they retain each usage. An attempt at printing grey on an old laser printer by using a 30% filter of cyan, magenta and yellow. The past printed pages are subtly recorded in the future print – a slowly breaking mechanism. Traces of the past multiply. Through multiplication new traces are acquired. False realignments heightening differences in minute moiré patterns. The process of production – visible in individual steps – going on forever – until it stops.
