• receiving the select graphic, at least one position for printing the select graphic, and a select spot color name for the select graphic, wherein the select spot color name represents a tone printable using at least one colorant of the digital printing device;
• generating a select spot color separation for the select graphic using a halftone screen to produce the tone represented by the select spot color, wherein the halftone screen is selected for printing the select graphic without a discernible dot pattern upon unmagnified viewing;
• and
• preparing raster data incorporating the select spot color separation for printing the select graphic at the at least one position on an item.

• receiving a select graphic, at least one position for printing the select graphic, and a select spot color name for the select graphic, wherein the select spot color name represents a tone printable using at least one colorant of a digital printing device;
• generating a select spot color separation for the select graphic using a halftone screen to produce the tone represented by the select spot color name, wherein the halftone screen is selected for printing the select graphic without a discernible dot pattern upon unmagnified viewing;
