Appeal No. 1997-3650
Application No. 08/206,658
31. A method of making a printed retroreflective
signing material, comprising the steps of:
A. providing a transparent film having a polymeric
sign surface;
B. providing an electrophotographic printing apparatus
having a reusable imaging surface;
C. providing an image defining means comprising (i) a
computer in which is stored a raster file, and (ii) a means
for translating an image from the raster file to the
reusable imaging surface;
D. defining an image to be printed by entering it into
the raster file;
E. translating the image from the raster file into a
latent image on the reusable surface;
F. providing dry toner powder comprising a colorant, a
binding agent for adhering the dry toner powder to the
polymeric sign surface, and a charge carrier;
G. applying the dry toner powder to portions of the
reusable imaging surface in the pattern of the latent image;
H. transferring the dry toner powder from the reusable
imagining surface to the sign surface;
I. fusing the applied dry toner powder to form a fixed
printed image;
J. providing a retroreflective sheeting material; and
K. laminating the transparent film to the
retroreflective sheeting.
At page 6 of the specification, the claimed “retroreflective
signing material” is defined as follows:
