摘要:
A method of producing an image onto a surface of a one-way vision display panel of the type which is constructed as a perforated membrane having an opaque light-reflective surface and a light-absorbing surface and whereby the image is clearly visible when viewing the display panel from one direction and wherein the perforated membrane permits substantially unobstructed through-viewing when viewing the display panel from a second, opposite direction. The method substantially eliminates the corona effect of the image while viewing the display panel in the through-viewing direction, the corona effect being the result of stray ink which has traveled from the image layer into the through-holes of the perforated membrane during the image printing process. The method includes the steps of: electrostatically transferring ink onto a transfer medium as a reverse image for temporarily holding the reverse image for later transfer to a surface of a perforated membrane; and transferring the reverse image from the transfer medium using heat and/or pressure in order to form a desired correctly oriented image onto only the solid bar portions of a surface of a perforated membrane without any substantial image transfer into or through the through-holes of the perforated membrane such that the correctly oriented image is substantially undetectable when looking at the one-way vision display panel in the second, opposite through-viewing direction.
