CUPRINT 96 4635 180 NPS TROUBLESHOOTING GUIDE 7 11 ADJUSTING PRINT QUALITY AND SPEED L The PostScript language provides a scheme for overwriting the internal transfer function of a printing device by providing the settransfer and setcolortransfer operators However some Xerox PostScript devices do not allow you to overwrite their internal transfer function Typically a master tries to replace the internal transfer function with a null transfer function such as settransfer or 0000 setcolortransfer If either of the above procedures is successful the transfer functions return the same color levels that are passed to them without modifying or mapping the level On printers which do not allow the overwriting of the transfer function the settransfer operator does not affect the mapping of gray values between the output of the print device and specified levels of color Note Settransfer actually sets the transfer functions for all four color components red green blue and gray to the same value The setcolortransfer operator sets the transfer functions individually 7 Smooth curves setflat PostScript masters that use the PostScript operator setflat produce inconsistent output across different PostScript printers setflat controls curve rendering smoothness PostScript curve operators use cubic Bezier control points to define the curve shape These curves can be rendered from straight line segments Normally the l
