The invention provides a three layered reprographic paper having improved strength, stiffness and curl resistance properties, and a method for making same. The paper has a central core layer made largely of cellulose and bulked with a bulking agent such as a diamide salt. A starch-based metered size press coating is pressed on both sides of the core layer, wherein the starch has a high solid content. The coating forms a three layered paper having an I-beam arrangement with high strength outer layers surrounding a low density core.

1. A paper or paperboard having improved bulk and stiffness comprising: a three layered single-ply I-beam structure having a higher density strengthened top layer, a lower density bulked central layer and a higher density strengthened bottom layer, wherein the central layer is a cellulosic core laye
1. A paper or paperboard having improved bulk and stiffness comprising: a three layered single-ply I-beam structure having a higher density strengthened top layer, a lower density bulked central layer and a higher density strengthened bottom layer, wherein the central layer is a cellulosic core layer, and the top and bottom layers are strengthening starch based, size-press applied coating layers that cover an upper and lower surface of the central layer with minimal penetration into the central layer such that starch is substantially absent from the central layer, and a bulking agent interpenetrated within the central layer, and wherein the top and bottom layers are formed are from a high strength starch based size-press solution having from about 6 to about 12 wt % starch solids. 2. The paper or paperboard of claim 1, wherein the ratio of the thickness of the top layer and the bottom layer compared to the thickness of the paper or paperboard is between 1:50 and 1:1.1. 3. The paper or paperboard of claim 1, wherein the basis weight of the paper is between 59 g/m2 and 410 g/m2 and the basis weight of each of the top and bottom coating layers are between 2 and 10 g/m2. 4. The paper or paperboards of claim 1, wherein the top and bottom layers have starch application controlled with a metered size press. 5. The paper or paperboard of claim 1, wherein the bulking agent is diamide salt based product. 6. The paper or paperboard of claim 1, wherein the bulking agent is made from a polymeric material in form of microspheres selected from the group consisting of methyl methacrylate, ortho-chlorostyrene, polyortho-chlorostyrene, polyvinylbenzyl chloride, acrylonitrile, vinylidene chloride, para-tert-butyl styrene, vinyl acetate, butyl acrylate, styrene, methacrylic acid, vinylbenzyl chloride and combinations of two or more or the foregoing. 7. The paper or paperboard of claim 6, wherein the central layer further comprises a retention agent. 8. The paper or paperboard of claim 1, wherein the central layer further comprises an additive selected from the group consisting of fillers, surfactants, sizing agents, or a combination thereof. 9. The paper or paperboard of claim 1, wherein the starch is selected from the group consisting of hydroxy ethylated starch, oxidized starch, cationically modified or enzymatically converted starch from any regularly used starch source, such as from potato, corn, wheat, rice or tapioca. 10. The paper or paperboard of claim 1, wherein the top and bottom layers further comprise a cross linking agent. 11. The paper or paperboard of claim 1, wherein the top and bottom layers further comprise a viscosity modifier. 12. The paper or paperboards of claim 1, wherein the top and bottom layers further comprise a pigment. 13. The paper or paperboard of claim 1, further comprising additives selected from the group consisting of polyvinyl alcohols, ammonium zirconium carbonate, borate chemicals, glyoxal, melamine formaldehyde, ground and precipitated calcium carbonates, clays, talc, TiO2, and silica, or a combination thereof. 14. The paper or paperboard of claim 1, wherein starch coat weights of each of the top and bottom coating layers are between 2 and 10 g/m2. 15. A method for making a paper or paperboard comprising the steps of: a) providing a furnish including cellulosic fibers and a bulking agent, b) forming a fibrous web from the papermaking furnish, c) drying the fibrous web to form a dried web, d) size-press treating the dried web with a high strength starch based size-press solution having from about 6 to about 12 wt % starch solids to form top and bottom coating layers on a top and bottom side of the dried web, and e) drying the size-press treated web to form a three layered single-ply having an I-beam structure comprising a higher density strengthened top layer, a lower density bulked central layer and a higher density strengthened bottom layer, and wherein starch is substantially absent from the central layer. 16. The method of claim 15, wherein the ratio of the thickness of the top and bottom coating layers compared to the thickness of the paper or paperboard is between 1:50 and 1:1.1. 17. The method of claim 16, wherein a starch solution of the high strength starch based size-press solution is pre-cooked with a borate chemical prior to the size-press treatment. 18. The method of claim 15, wherein the basis weight of the paper is between 59 gsm and 410 gsm and the basis weight of each of the top and bottom coating layers are between 2 and 10 gsm. 19. The method of claim 15, wherein the size-press treatment uses a metered size-press. 20. The method of claim 15, wherein the bulking agent is a diamide salt based product. 21. The method of claim 15, wherein the furnish further contains an additive selected from the group consisting of: fillers, surfactants, or a combination thereof. 22. The method of claim 16, wherein the starch is chosen from a group comprising of: hydroxy ethylated starch, oxidized starch, cationically modified or enzymatically converted starch from any regularly used starch source, such as from potato, corn, wheat, rice or tapioca. 23. The method of claim 15, wherein the size-press solution further contains an additive selected from the group consisting of: polyvinyl alcohols, ammonium zirconium carbonate, borate chemicals, glyoxal, melamine formaldehyde, ground and precipitated calcium carbonates, clays, talc, TiO2, and silica, or a combination thereof.
