Don't know if this would work or not, but all the hardware stores here sell
an ultrasonic humidifier, which blows out a fog from the nozzle. I believe
they use a piezoelectric transducer to produce the tiniest water droplets.
You would need to hook up a hose to direct the output to your print or,
bring the print to the humidifier. Where I live they cost around $60.
