BIAXIAL LEVELING OF MAGNETIC PLATES Russian patent published in 2013 - IPC B05D3/14 

FIELD: process engineering.

SUBSTANCE: invention relates to printing and can be used for imaging with the help of ink containing colour-changing metal or magnetic plates. Method of leveling multiple directed nonspherical plates supported by lengthwise tape with coating containing nonspherical plates oriented in magnetic field. First and second magnets are arranged at first side of tape feed and second magnet is arranged between first and third magnets on second side of tape feed path. First and third magnets feature identical polarity. Second magnet features polarity unlike that of said first and third magnets. First magnetic field surrounding the feed path exists between first and second magnets. Second magnetic field surrounding the feed path exists between second and third magnets. Magnets are arranged so that multiple nonspherical plates directed by magnetic field and moved along tape feed path make first turn on passing by second magnet during relative displacement of tape and magnets. Proposed method comprises relative displacement of at least tape supporting the plates, or magnets that make two pairs of complementary tractive magnets. Multiple plates oriented in magnetic field can perform multiple turns.

EFFECT: higher light reflectance, better chromatic properties of printed articles.
