摘要:
A method and apparatus for printing an image on a large surface area or walkway provides for imagewise marking of the surface with a color marking solution, to form a visible image on the surface during an image recording mode of a marking engine. The marking engine includes a scanner and the marking engine moves along the surface and operates the scanner to sense a crude image upon the surface and generates data signals representing the crude image or boundaries defined by the crude image scanned. In response to data signals the marking engine is operated to print an enhanced image of the crude image and/or to color the crude image so that the printing overlies the crude image.

Printing apparatus for printing an image on a selected surface, includes a print head for printing the image, respective supports for the print head that allow the print head to translate left and right along an x-axis and to translate up and down along a y-axis perpendicular to the x-axis to move the print head over the selected surface, and respective supports for the print head that allow the print head to translate forward and rearward along a z-axis perpendicular to the x-and y-axes and to swing in a plurality of curves from the z-axis in order to adjust the print head for surface variations on the selected surface.

A method of printing a multi-color image on a particular surface, using a digital image file having a discrete number of pixels that collectively represent the multi-color image, comprises: determining a relatively large area of the multi-color image that is represented by less than the total number of pixels, but which pixels each have a common printing color component; forming an outline of the determined relatively large image area on the particular surface the multi-colored image is to be printed; providing a colored receiver layer within the formed outline that is the same color as the common color component, but which color has a selected low color value; applying a non-colored receiver to an area on the particular surface that is outside the formed outline on the particular surface, to provide a non-colored receiver layer on the particular surface in addition to the colored receiver layer on the particular surface; modifying the digital image file by subtracting the selected low color value from the pixels representing the relatively large area, to provide a printing file for printing the multicolor image; and printing the multi-color image on the colored and non-colored receiver layers, using the printing file, to make a print of the multicolor image on the particular surface.

A method and apparatus for printing an image on a large surface area or walkway provides for imagewise marking of the surface with a color marking solution, to form a visible image on the surface during an image recording mode of a marking engine. A vehicle supports the marking engine and includes a drive that engages the surface at plural locations and moves the marking engine relative to the surface. The marking engine is located outboard of an area defined by lines connecting the plural locations so that during operation of the marking engine during the image recording mode the drive does not engage areas of the surface that have been previously imagewise marked.

A method of printing a multi-color composition having a relatively large background area with a prevailing color and different color smaller objects superimposed on the relatively large background area, comprises: uniformly applying a colored substance that is not a printing ink, and has the same color as the prevailing color of the relatively large background area, on a particular surface; and printing the smaller objects on the particular surface, using different color printing inks.
摘要:
A method of providing an image on a media having a image-receiving layer and a protective overlayer, comprising the steps of providing an image on the image-receiving and providing machine-readable indicia on said protective overlayer by varying the temperature of a thermal head used to apply the protective overlayer.

An automated film slide orienting and mounting system includes at least one detector for detecting the orientation of film, a knife assembly for successively cutting the film to generate film segments, a rotatable table for orienting the film segments into a proper orientation, a set of driver assemblies for progressively moving each film segment for insertion into a slide mount, and a magnetic writing device for writing the orientation of the film segment magnetically onto the slide mount in a region of magnetic material disposed upon each slide mount.

A film projector for use with frames of processed photographic film having frame-associated image orientation data. The film projector has a light source that emits a collimated beam and a film holder that is disposed to hold individual frames of film in the beam. The film holder is pivotable between a first and second orthogonal orientations. An optical projection system receives the beam from the film holder. The optical system propagates and focuses at least a portion of the beam on a viewing plane external to the projector. A sensor is disposed to read the frame-associated image orientation data. The sensor produces a signal responsive to the image configuration information. A controller receives the signal from the sensor. A repositioner is connected to the film holder. The repositioner is operatively connected to the controller to move the film holder between the orientations responsive to the controller.

Film slides bearing encoded data and methods for preparing them. The film slides each include a transparency having an image section bearing a visual image and a data section bearing encoded data relating to the visual image; and a mount including a data portion bearing magnetically recorded data relating to said visual image. The data portion of the mount physically supports the transparency.
