Abstract: The present invention concerns an inking for a flexographic or a rotogravure press. The inking system uses a very small amount of ink coupled with an ink source made of two tanks with two different inks. Thanks to feedback given by measuring the output directly on the printed support, the system mixes the ink in the optimal proportions to ensure an optimal printing quality at any time. It can compensate any effect due to environmental changes like the humidity or the temperature. This system, coupled with a seven colours press allows for the replacement of spot colours in most cases thereby saving times and costs.

Abstract: Method and system are disclosed for characterizing and quantifying composite laminate structures. The method and system take a composite laminate of unknown ply stack composition and sequence and determine various information about the individual plies, such as ply stack, orientation, microstructure, and type. The method and system can distinguish between weave types that may exhibit similar planar stiffness behaviors, but would produce different failure mechanisms. Individual ply information may then be used to derive the laminate bulk properties from externally provided constitutive properties of the fiber and matrix, including extensional stiffness, bending-extension coupling stiffness, bending stiffness, and the like. The laminate bulk properties may then be used to generate a probabilistic failure envelope for the composite laminate.
