Abstract
A method and apparatus is shown for leading an imaging surface relative to an imaging beam under two controls where first and second leading spaces are produced. The second leading space being a different width than the first leading space, is distributed among the first leading space separating a plurality of line pairs. The second leading space is interspersed within first leading spaces and is visually less perceptible to the human eye. A pattern describing a matrix of row and column positions control the spacial movement of an imaging beam and after each leading step the imaging beam reproduces the original graphic within each of the elemental image positions or image areas of the matrix.

A method of interspersing a leading space of a first width produced between pairs of a series of images formed by deflection of an imaging beam, by a leading step in a first direction over a plurality of lines separated by a leading space of a second width produced by said leading step in said first direction, and wherein said lines are formed by image areas in a graphic image located on an imaging surface having at least first and second dimensions extending in said respective first and second directions and comprising the steps of:
- a. deriving signals indicative of the information content of said image areas,
- b. reproducing said image areas, responsive to said signals, on said image surface at predetermined locations, to form a succession of said lines of said images in said second direction,
- c. and, wherein said step of reproducing includes the steps of spacing said reproduced image areas in separate leading steps, producing leading spaces of said second width in said first direction to form said succession of said lines extending in the said second direction, and the step of interspersing one said leading space of said first width, produced between the pairs of said images in said leading space of said second width between a plurality of said line of images.
An apparatus for making the leading space between the image areas, forming lines in a graphic image on an image surface, said image surface having at least two dimensions including means for deriving signals indicative of the information content of a plurality of image areas, means responsive to said signals for reproducing said image areas in lines of said imaging surface, said reproducing means including an imaging means, means for displacing said imaging means relative to said imaging surface in the direction of a first dimension corresponding to a succession of said lines and in the direction of a second dimension corresponding to the direction of said lines, said means for displacing said imaging means, leading said reproduced images from line to line in a succession of respective separate leading steps, and means for distributing the leading space formed by said respective separate leading steps between a plurality of line pairs.
An apparatus for interspersing a leading space of a first width over the leading spaces of a second width between image areas forming lines in a graphic image on an imaging surface, said imaging surface having at least two dimensions in respective first and second directions, and comprising
- a. means for deriving signals indicative of the information content of a plurality of said image areas,
- b. imaging means responsive to said signals for reproducing said image areas in lines in said second direction on said imaging surface,
- c. means for spacing said imaging areas in a successive set of leading steps in said first direction and producing a leading space between said lines of a second width,
- d. said means for spacing including means for producing a leading space between said lines of a first width and means for interspersing the said leading space of said first width over the said leading spaces of said second width.
