Abstract: A method and apparatus is disclosed for gravure coating a liquid reactive with the atmosphere onto a web. The gravure apparatus comprises an engraved gravure cylinder, an impression roller backing the web and pressing it onto the gravure cylinder to form a nip, a curtain or jet formation means to wet the surface of the gravure cylinder, and a doctor blade means for wiping excess coating liquid from the surface of the gravure cylinder prior to the nip. A shroud encompassing the gravure cylinder and the curtain or jet formation means creates a first zone between the nip and a partitioning baffle extending from the shroud, a second zone between the partitioning baffle and the doctor blade means, and a third zone between the doctor blade means and the nip. A gas non-reactive with the coating liquid is supplied to each zone by a gas distribution means such that the reaction rate of the coating liquid with the atmosphere is greatly reduced and the curtain or jet is not disrupted.

Abstract: An electronically originated image is converted into a modified electronic image simulating an image originated from a film system and converted into an electronically displayed image. The technique employed is based on a set of electronic camera system spectral product curves that are substantially approximated by a linear combination of a set of spectral product curves characteristic of the film system. An image is captured having red, green and blue exposure signals resulting from these electronic camera system spectral product curves, and the red, green and blue exposure signals are then converted into a modified electronic image simulating an image originated from a film system and converted into an electronically displayed image. Because of the linear approximation between the spectral product curves, the conversion step can be performed by a matrixing operation.
