Abstract:
A method and a carrier medium carrying code to execute a method (200) of designing a carton. The method (200) includes accepting (203) carton structural information, forming (207) a 2D unfolded model of the substrate that when cut and folded forms the carton, and forming (209) a 3D model of the carton. The method further includes displaying a 2D view of the unfolded carton design, and a perspective view of the 3D model. A user has the ability to manipulate the view of the 3D model, and also to select (213) a flap of the carton on perspective view. As a result of the selecting, the method modifies the 2D unfolded view to be of the selected flap shown in an orientation suitable for designing the selected flap. The user designs (219) the flap and the method accepts the design. The method includes modifying the perspective view of the 3D model to include any changes made in the design.

Abstract:
A modulator device for modulating a pulsed laser beam in response to a modulation signal, the pulsed laser beam comprising a sequence of laser pulses at a predetermined pulse rate, the modulator device comprising a modulation medium and a driver circuit for applying a control signal to the modulation medium. The driver circuit is adapted to receive the modulation signal and a clock signal indicative of the pulse rate of the laser beam and to generate the control signal as a pulsed signal having a frequency determined from the clock signal, wherein the pulsed control signal is modulated by the modulation signal.
Abstract:
Images are transferred to printing plates by illuminating light-responsive materials with patterns corresponding to the images to be printed. The present invention provides for the transferring of an image by the combined flux from two or more beams of light. Particular embodiments ablate the mask printing plates for CTP systems by the combined illumination from a first, broad beam and a plurality of controllable, pulsed beams that co-illuminate the plate with the first beam. The resulting system and method is less expensive than the prior art and produces a printing plate more efficiently and with improved productivity than the prior art.
Abstract:
A method of exposing imaging data (542) onto a sensitized medium (550) including exposing K sets (380, 480) of N of tracks (1, 2, 3, 4) onto the medium according to a corresponding part of imaging data, each successive set being a pixel distance apart in a fast scan direction (301, 401). The method further includes exposing L sets (390, 490) of N tracks onto the medium with an offset of M pixels in a slow scan direction (302, 402) substantially perpendicular to the fast scan direction, according to a second corresponding part of imaging data. The method includes repeating alternately exposing K sets and L sets of N tracks until the complete medium is exposed along the fast scan direction. During or after the alternately exposing K sets and L sets, there is progression in the slow scan direction such that after exposing the complete length of N tracks of exposed pixels, the next N tracks match along the medium at the start of the next N tracks.
Abstract:
A method to aid designing flexible packaging for wrapping around a solid object and finalizing the packaging. The method includes accepting a description of the surface of a sheet of packaging material after wrapping around the solid object and finalizing, using a mapping of points in the 2D plane of the sheet of the packaging material to the corresponding points in the 3D surface of the wrapped and finalized packaging. The method further includes displaying the surface of the wrapped and finalized packaging or displaying graphic elements on the surface of wrapped and finalized packaging. A version includes pre-distorting graphics to correct for any distortions to graphics that occurs during the wrapping and finalizing process, and generating press-ready graphics from the pre-distorted graphics for printing onto the surface of the sheet of packaging material.

Abstract:
A method and apparatus to aid the loading and unloading of flexographic plates to and from an imager. The apparatus includes a magazine containing a plurality of compartments each for holding a single flexographic plate, the compartments arranged vertically, and movable in a vertical direction, a lifting mechanism to lift and lower the compartments; and a control system to control the lifting and lowering by the lifting mechanism The control system is such that a particular compartment is moved from its rest vertical position at a rest horizontal position to a loading vertical position and a loading horizontal position at which the particular compartment is at a height for loading onto the imager. The loading is automatic and in the case that the plate includes a protective sheet thereon, the loading includes removing the protective sheet from the plate.
Abstract:
This invention relates to a method of controlling light intensity in connection with the exposure of photosensitive material in an imagesetter/platesetter, which comprises a light source for illuminating said photosensitive material, wherein the light intensity of said light source is increased to a predetermined level ensuring a sufficiently steep transition between exposed and non-exposed material, and random image information representing material for exposure is modified so as to reduce the time during which the light source is active. The invention also relates to an apparatus for the same. A method and an apparatus eliminating/reducing the phenomenon spot wear are provided hereby.
