Computerized system for simulating paper sheet formation and the

Abstract

To provide a simulation of the formation of a sheet of paper and the appearance of print thereon, a computerized system is adapted to receive input parameters related to a type of headbox stock desired, the fabric upon which the paper is to be formed, the paper machine to be used, and the printing process desired. Data relating to the actual production of paper is configured to simulate a series of fibres being dropped onto the surface of the fabric to create a mat. After a sufficient amount of fibre has been simulated as being dropped onto the fabric creating a fibrous mat, the system will indicate a final sheet has been completed when it has the desired basis weight as initially inputted by the user. After a final sheet of paper is deemed finished a report pertaining to sheet characteristics is generated. The report provides the user with data relating to fibre retention, a display of the simulated sheet along with its density variations, surface characteristics, and structure. The system, adapted to accept data relating to the type of printing process, configures such data with that already inputted, so as to provide a simulation of ink printing on the simulated sheet. The user thus has a visual output representative of the quality that a final physical sheet of paper would possess after manufacture and printing thereon.
