StudioRIP Trapping
The StudioRIP Trapping option. In the high quality reproduction of colour documents, gaps caused by misregistration of a printing process are commonly avoided by creating an overlapbetween areas of adjacent colour called a trap. Level 3 Postscript defines rules and parameters for trap generation that RIPs should follow in the Postscript interpretation and rendering process. StudioRIP has a proprietary raster based technique for trapping with a rich set of features. Over and above the standard trapping features, here are some key features that other RIPs may not have.
Narrowed traps
there are cases where the full width of the trap does not fit into the available spread area, in which case StudioRIP will reduce the trapping automatically.
Sliding traps
as the color varies continuously across a vignette, the trap might jump suddenly from one side of the boundary to the other at some point. StudioRIP avoids this using the sliding trap technique.
Anamorphic traps
the misregistration in the X and Y directions in the printing process might be different. StudioRIP can compensate this by applying different trapping in X and Y directions.
Feathered traps
a blurred trap has a more pleasant look than the traditional sharp traps.
Colour reduction
the visual impact of the trap can be minimized by reducing the density of the trap to match the original density.
Density limitation
a color reduction that acts selectively for traps with a density over a certain limit, relative to the original density.
High quality shapes
excellent behavior in junctions, in the proximity of a third color, and with slightly different colours.
