Abrégé anglais




The invention relates to printed stonewall panels and method for 3D
reproduction of the
image via 2D printing techniques onto a non-uniform irregular planar surface
created via the
transmission of the digitized 3D information to specific machineries onto a
specified
substrate. More precisely, an optical digital mean of interpreting the 3D
information from the
photographic image associated with a numerically controlled engraving/milling
machine
(router) to transfer the images 3D elements onto a substrate associated with a
high precision,
large surface, printing machine combined with a high precision registration
and positioning
mean for printing the image on the engraved substrate to obtain an image with
actual relief
resulting in a 3D representation of the original photographic image.

ix. Applying a clear coat.

7. A method according to claim 6, wherein step (i) means translating a high-
resolution
digitized picture into a digitized rendering of surface with low and high
points.

8. A method according to claim 6, wherein step (ii) means creating a textured
base on the
pictured object.

9. A method according to claim 6, wherein step (iii) means creating a printing
and
engraving digitized file based on the pictured object.

10. A method according to claim 6, wherein step (iv) means selecting a
substrate material
based on the application while using a 3-axis router to engrave the relief.

11. A method according to claim 6, wherein step (v) means applying a first
layer in order
to stabilize the substrate and to present surface roughness to prevent the ink
from
sliding off abrupt edges. Abrupt edges are defined as edges exceeding 75
degrees.

12. A method according to claim 6, wherein step (vi) means defining the height
of the
printer head, the printing speed, the ultra-violet lamp intensity, number of
layers and
the saturation level.

13. A method according to claim 6, wherein step (vii) means verifying the
registration
accuracy by first printing a clear layer, second sliding the 3D surface under
the
transparency without moving said acetate, third aligning the 3D pattern with
the
pattern printed on the transparency, forth conducting a visual inspection and
last
applying registration corrections. Repeat until registration is accurate to
less than
{fraction 1/128} inches, (0.2mm).

14. A method according to claim 6, wherein step (viii) means selecting the ink
and a flat
bed printer using ultra-violet means for curing the ink.

15. A method according to claim 6, wherein step (ix) means applying manually a

protective layer, whereas the said protective layer is a latex base clear
coat.

16. A system according to claim 1, wherein the substrate is Sintra.TM. and

v. Add a third layer on top of the merged layers with mode set to darken,
opacity set to 50%;
vi. Using a paintbrush with feathers set to 100% black, draw the mortar,
whereas the said paintbrush diameter defines the width of the mortar,
whereas the said feathers determine the angle at the edge of the stone;
vii. Save in a tiff file before merging the third layer;
