    摘要: Disclosed herein are apparatuses for screen printing on a surface of a three-dimensional substrate comprising a substantially rigid, substantially planar frame having a perimeter defining a region within the perimeter having a given surface area; and a screen attached to the frame and extending across at least a portion of the surface area, wherein the screen comprises a first portion through which a liquid printing medium can pass onto a proximate three-dimensional substrate; and a second portion coated with an emulsion substantially preventing the liquid printing medium from passing through the second portion of the screen, wherein the screen has a fixed tension of less than about 20 N/cm. Methods and systems for screen printing on a surface of a three-dimensional substrate are also disclosed herein.
