    摘要: An ink jet recording method uses an ink jet recording apparatus including a plurality of heads arranged in parallel in a first direction, each of which ejects droplets of a different radiation-curable ink composition onto a recording medium, and first light sources provided for corresponding heads so as to be disposed at a predetermined side of the corresponding heads. The first light sources emit active radiation to irradiate the droplets on the recording medium. The method includes ejecting droplets of the ink compositions from the heads onto the recording medium, and performing a first irradiation by irradiating the droplets of each ink composition with the active radiation from the corresponding first light source at an irradiation energy within 500 ms after the droplets have landed. The irradiation energy is in the range of 5% to 10% of the energy E90 at which the ink composition is 90% cured.

Preferably, three or more magnetic blind bodies 2 are coupled in a row so as to form a closed magnetic path. The blind bodies 2a, 2b may be stacked side by side in such a manner that the blind core plane Fa, Fb are parallel to each other and orientation of the slat central axes in each blind body 2a, 2b being selected so as to optimize attenuation of magnetic field across the magnetic shield structure.
