Phaser 750 Color Printer
Troubleshooting Phaser 750 Printers 
This concept is known as a what you see is what you get (WYSIWYG) problem. 
What you actually see on your monitor is not really what you get from the 
printer. The monitor is able to reproduce millions of colors using RGB in 256 
intensities. Printers use CMYK with the same relative saturation to reproduce 
significantly fewer colors. The effect is that monitors display colors outside the 
printer’s gamut. 
This primarily happens with blue colors, although other colors can be affected. 
The difference in color reproduction combined with gamut disparities can cause 
printed output that does not match the monitor.
The easiest solution involves changing the TekColor Corrections. For example, if 
you want to match the printed colors to the monitor, use the sRGB Display color 
correction.
The most accurate approach is to use the RGB color charts which ship with the 
printer. These color charts represent which colors from the RGB gamut the 
printer is capable of reproducing. Each color from the chart has corresponding 
values for Red, Green, and Blue. Using these values in the application allows 
exact color matching.
