Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

What is claimed is:

1. A printing system capable of accurately positioning a lenticular array in registration with a rectilinear raster comprising:

a printer that is capable of printing onto a printable surface, the printer having a main support surface on which the printable surface rests; and

a series of raised parallel relief features being spatially formed along a printable substrate that is supported by the main support surface, wherein the raised parallel relief features are raised to a sufficient height above the printable substrate such that when the lenticular array is disposed upon the raised parallel relief features, each raised parallel relief feature fits and is disposed within a valley formed between two respective adjoining lenticules of the lenticular array.

2. The printing system of claim 1 , wherein the printer comprises a flatbed printer and the main support surface comprises a planar surface.

3. The printing system of claim 1, wherein the printer comprises:

at least one ink reservoir;

a printhead capable of ejecting ink onto the printable surface, the printhead including at least one nozzle;

a mechanical actuation system configured to move the printhead in at least one axis; and

an electronic system regulating motion of the printhead.

4. The printing system of claim 1 , wherein the series of raised parallel relief features are formed by the printer.

5. The printing system of claim 1, wherein the printable substrate is detachably secured to a portion of the main support surface of the printer.

6. The printing system of claim 5, wherein the printable substrate is detachably secured to the portion of the main support surface by tape along edges of the printable substrate.

7. The printing system of claim 1, wherein the main support surface comprises a vacuum table.

8. The printing system of claim 1, wherein the series of raised parallel relief features are formed of UV curable inks deposited on the printable substrate by the printer.

9. The printing system of claim 1, wherein a lenticulated face of the lenticular array has a physical pitch associated therewith and the series of raised parallel relief lines has a pitch substantially equal to the physical pitch of the lenticulated surface.

10. The printing system of claim 1, wherein the printable substrate comprises a sacrificial substrate that is formed of a material that is at least partially permeable to air and the main support surface comprises a vacuum table.

11. The printing system of claim 1, wherein the printable substrate comprises the main support surface of the printer.

12. The printing system of claim 1, wherein the series of raised parallel relief lines comprise raised ridges that do not merely contact the lenticules at points of tangency to the lens relief but instead substantially form a relief that is geometrically conformal to a region of a lens sheet that is part of the lenticular array.

13. The printing system of claim 1, wherein the printable substrate comprises an apertured banner mesh.

14. The printing system of claim 1, wherein the series of raised parallel lines is intrinsically matched to a raster of the printer and also at least substantially matches a physical pitch of lenses of a lenticulated sheet that defines the lenticular array, the series of raised parallel lines deterring movement of the lenticulated sheet across an axis of the lenticules.

15. The printing system of claim 1, wherein the series of raised parallel lines comprises a relief structure in the form of quantized ridges formed by a multilayer application of ink that provides a quantized geometry that is complementary to a raised lenticular surface of the lenticular array.

16. The printing system of claim 15, wherein each quantized ridge is formed of a plurality of layers of ink, each ink layer deposited to provide a different line width.

17. A printing system capable of accurately positioning a spherical lens array in registration with a rectilinear raster comprising:

a printer that is capable of printing onto a printable surface, the printer having a main support surface on which the printable surface rests; and

a plurality of quantized concavities being spatially formed along a printable substrate that is supported by the main support surface, wherein the quantized concavities are constructed such that when the spherical lens array is disposed upon the quantized concavities, each spherical lens fits and is disposed within one

respective quantized concavity formed on the printable substrate, thereby locating and deterring movement of the spherical lens array relative to the main support surface.

18. A method of forming an alignment grid to register a prefabricated lenticular sheet with a rectilinear print raster of a printing device, comprising:

determining a physical pitch of a lenticulated face of the lenticular sheet; and printing a pattern of raised parallel lines upon a substrate mounted upon a surface of the printing device, wherein the pattern of raised lines has a pitch substantially equal to a physical pitch of the lenticulated face and are configured for reception within valleys formed between lenticules of the lenticulated face for deterring movement of the lenticular sheet across an axis of the lenticules.

19. The method of claim 18, further including the step of:

locating the lenticulated face of the lenticulated sheet such that the raised lines are located between vertices of the lenticules; the raised lines at least partially occupying the valleys between the lenticules, and wherein the raised lines are in at least partial contact with the lenticules such that the lenticules are located an indexed relationship with the rectilinear print raster.

20. A method of registering a lenticular sheet with a rectilinear print raster of a printing device that has an alignment grid defined by a plurality of raised parallel ridges, comprising:

locating a lenticulated face of the lenticulated sheet such that the raised ridges are located between vertices of lenticules of the lenticulated face; the raised ridges at least partially occupying the valleys between the lenticules, and wherein the raised ridges are in at least partial contact with the lenticules such that the lenticules are located an indexed relationship with the rectilinear print raster.

21. A method of printing a design upon a prefabricated object carrying a relief pattern upon one of its faces, such that said design is printed in registration with said relief pattern, said printing being carried out upon a face opposite to the face upon which said relief pattern is formed, comprising the steps of:

printing a raised alignment pattern defined by a pattern of inverse relief features upon a bearing surface held in a plane parallel to the bed of said flatbed printing device, said inverse relief features geometrically and dimensionally corresponding in a an inverse and conformal manner to recesses in said patterned object,

mechanically engaging said surface relief pattern upon said prefabricated object with said inverse relief features upon said bearing surface, such that the relative positions of said prefabricated object and said bearing surface are substantially constrained in at least one axis, and

printing a design upon said face opposite to the face upon which said relief pattern is formed.
