Abstract
A method of forming a moulded and printed product from pulp material including the steps of: forming a pre-form mould to have one or more planar surfaces, compound conjoined planar surfaces and/or two dimensional curved surfaces; transferring an amount of pulp slurry material to the pre-form mould; forming a moulded pre-form from the transferred pulp slurry material; applying printing to the planar and/or dimensional curved surfaces in a pre-distorted configuration; and moulding the printed pre-form to a different final shape whereby the printed surfaces retain the printing without running and the printing conforms to a desired post distortion configuration.
