It’s a major pain when a pen in my pocket leaks and ruins my favourite shirt or a glass of Medoc somehow misses my mouth and defaces a much-loved tie.
Today’s invention is a scanner/printer which examines any such stain and decides which shape it most closely resembles in a database of stored items. This would take into account the colour of the stain and the probability of overprinting with a darker colour.
The device then offers the user the chance to overprint the stain with either a one-off ‘logo’ or a repeating pattern based on the modified stain shape. Once a choice of disguise shape has been chosen, the printer applies this in order to obscure the stain and make the item of clothing usable again.
