Method of controlling ink film thickness on a printing plate

A method of controlling an ink film thickness in an AM halftone region of a printing plate or an intermediate image carrier on a digital press, comprising forming in said AM halftone region a plurality of halftone dots, each of said halftone dots comprising at least a first ink-receptive ring enclosing at least one concentric non-ink-receptive portion and a central solid ink-receptive dot concentric within the first ink-receptive ring.

A method of controlling an ink film thickness in an AM halftone region of a printing plate or an intermediate image carrier on a digital press, comprising forming in said AM halftone region a plurality of halftone dots, each of said halftone dots comprising at least a first ink-receptive ring enclosing at least one concentric non-ink-receptive portion and at least a second ring within and concentric with the first ink-receptive ring.

A method of controlling an ink film thickness in an AM halftone region of a printing plate or an intermediate image carrier on a digital press, comprising forming in said AM halftone region a plurality of halftone dots, each of said halftone dots comprising at least a first ink-receptive ring enclosing at least one concentric non-ink-receptive portion, and in at least some of said halftone dots, at least a second ring concentric within the first ring.

A method of controlling an ink film thickness in an AM halftone region of a printing plate or an intermediate image carrier on a digital press, comprising forming in said AM halftone region a plurality of halftone dots, each of said halftone dots comprising at least a first ink-receptive ring enclosing at least one concentric non-ink-receptive portion and forming as a component of at least some of said halftone dots at least a second ring concentric within the first ring, and forming as a component of at least some of said halftone dots a central solid ink-receptive dot concentric with the first ring.

A computer readable medium comprising computer readable code, wherein the code is adapted to generate a digital AM halftone image output comprising a plurality of halftone dots each comprising at least one ink-receptive ring enclosing at least one concentric non-receptive portion and at least some of said halftone dots comprising at least two unconnected ink-receptive portions.

A computer readable medium comprising an encoded digital AM halftone image output, said output comprising a plurality of halftone dots each comprising a first ink-receptive ring enclosing at least one concentric non-ink-receptive portion and at least some of said halftone dots comprising at least two unconnected ink-receptive portions.

A method of controlling an ink film thickness in an AM halftone region of a printing plate or intermediate image carrier on a digital press, the method comprising forming in said AM halftone region a plurality of halftone dots, each of said halftone dots comprising at least one ink-receptive ring enclosing at least one concentric non-ink-receptive portion and at least some of said halftone dots comprising at least two unconnected ink-receptive portions, wherein the plurality of halftone dots provides a range of percent density values selected from a continuum of possible density values defined by an algorithm, said algorithm providing a minimum possible density value of zero and a maximum possible density value of at least 95%.
