• An ink can appear to be very light, but if it is set to opaque, a darker color will spread into the ink.
• Opaque inks will be the shape-defining color in a border between a normal ink and an opaque ink.
• In borders composed of two opaque inks, the ink that is later in the print order will be the shape-defining color.
• An opaque ink is considered solid if its tint value is greater than the value for the Black Color Limit. Where a solid opaque ink overprints another color, the combination of the two inks forms a rich black area. The underlying color is always choked back from any borders with rich black objects, leaving the opaque ink to define the border shape.
• An opaque color is not spread.
• Other colors can trap to an opaque color.
• An object covered by an opaque color can be choked back when bordering an unpainted object such as the substrate.
• Trap direction is determined by print order.
