Method of metal mask and manufacturing method of metal mask

A design method of a metal mask, a manufacturing method of the metal mask and a computer-readable storage medium are provided. The design method of a metal mask includes: calculating amounts of deformations of the metal mask in two directions perpendicular to each other based on a stretching force of the metal mask in use and deformation properties of the metal mask in the two directions; and compensating the deformations of the metal mask in the two directions by compensation amounts for the deformations, which are identical and opposite to the amounts of the deformations of the metal mask in the two directions, respectively.

Method of making a nonwoven web

Soft point bonded nonwoven webs, and methods of making the same, are described that utilize a pattern of small, discrete bond points in a sequent pattern that together form macro-elements. The macro-elements are themselves positioned and aligned within a pattern such that mechanical stretching operations on the point bonded nonwoven webs yields soft and bulky fabrics but with reduced incidence of tearing or rupturing of the individual bond points.
