Abstract: A system for forming an image on a flexographic media includes a digital front end that provides a screened image; locating transition points from data regions to non-data regions in said screened image; determining a distance between pixels in adjacent data and non-data regions; if the distance is greater than a predetermined distance modify said screened image to remove a shoulder of pixels at the transition point; and an imaging device the screen modified image on the flexographic media.

Abstract: A method for forming an image on a flexographic media includes providing a screened image; locating transition points from data regions to non-data regions in said screened image; determining a distance between pixels in adjacent data regions for each transition point; if the distance is greater than a predetermined distance, modify said screened image to remove a shoulder of pixels in contact with the transition point; and forming the modified screened image on the flexographic media.

Abstract: An apparatus for enhancing halftone image (204) appearance for imaging on a flexographic plate (108) includes a computer (130) adapted to receive a halftone image; an analysis element adapted to scan the previously produced halftone image and to detect areas (404) in the previously produced halftone image which are populated with dots which are smaller than a previously set minimal dot size value; an enhancement element adapted to replace the small dots with a reduced number of dots wherein each of the reduced number of dots are larger in size (504) than the small dots and wherein each of the reduced number of dots maintain original geometric characteristics of the small dots to create an enhanced halftone image; and an imaging head adapted to image the enhanced halftone image on an imaging system.

Abstract: A method for enhancing appearance of a halftone image (204) for imaging on a flexographic plate (108) includes retrieving the halftone image from a data storage device (132); setting a minimal dot size value for printing; analyzing the halftone image with a computer (130); detecting areas (404) in the halftone image populated with a plurality of dots smaller than the minimal dot size value; replacing the plurality of dots with a reduced set of dots wherein each of the reduced set of dots are larger in size (504) than the plurality of dots and wherein each of the reduced set of dots maintains an original geometric characteristics of the plurality of dots; and saving the reduced set of dots.

Abstract: A method of building threshold matrices for stochastic screening by using the actual size and shape of imaged pixel and/or pixel agglomerate instead of the nominal one, in the stage of calculating appropriate threshold matrices. For each relevant combination of imager and imaged media, a matrix with desirable blue-noise-like characteristics is created from actual imaged pixels and/or pixel agglomerates, taking into account their overlap when placed in close proximity.

Abstract: The invention is directed to a method for fabricating a micro or nano structure such as an optical waveguide incorporating an emitting surface in the form of a lens. The structure is fabricated on the basis of a theoretical simulation of the structure, with the parameters of the structure being characterized by geometric and light profiling using near-field and far-field monitoring. The results of the characterizing are compared iteratively with the simulation during fabrication.
