First Claim
1. A method of printing on a cover sheet for a soccer ball, the method comprising the steps of:
- providing a cover sheet of a flexible substrate composite comprising a web, woven fabric, non-woven fabric, and paper, wherein the paper has a specific density, thickness, elasticity, flexibility, transparency and strength, and wherein the cover sheet has an outer side and an inner side, one of the woven fabric and non-woven fabric forming the outer side;
selecting a design pattern or a picture to be printed at the soccer ball;
digitally printing the outer side of the cover sheet using sublimation printing method, to form a printed cover sheet;
applying a transparent coating to the printed side of the printed cover sheet wherein the transparent coating is one of a layer of transparent material or a thin film of transparent material fixed with transparent adhesive material to the printed side of the printed cover sheet;
cutting out of cut-outs from the printed and coated cover sheet, of required size and shape;
fixing the inner side of the printed and coated cover sheet with an outer surface layer of bladder of the soccer ball at which printing is required by using one method among applying a layer of adhesive, applying molding method and stitching between the inner side of the printed and coated cover sheet and to the outer surface layer of the soccer ball to form final product.

Abstract
This invention is about a digital printing method of cover sheet of a flexible material of required features of density, flexibility and thickness. This method includes steps of printing a cover sheet of woven or non-woven fabric, by using digital or computerized printing techniques, either direct printing or by transfer paper printing or sublimation printing technique. The printed side of the cover sheet is laminated or coated with a clear film of flexible transparent material like polyurethane, thermoplastic polyurethane, polyethylene or polyvinylchloride. This laminated or sealed printed and coated cover sheet may be fixed to different fabric, foam or of outer surface layer of an article at which printing is required. The said article may be sport'"'"'s good, sport'"'"'s wears, dresses, footwear, furniture covering sheets and vehicle items covers etc. The novel method of making cover sheet enables customized printing at required articles at user request with many design printing possibilities. While use of water based ink for digital printing provides an environment friendly, efficient, and durable method of printing the cover sheets of these products.
