Density, gamma correction, screen frequency, and screen angles are some of the factors that affect print quality. Your QMS 1060E Print System is a multiresolution printer. This technology gives you more flexibility to control the print quality factors. About Print Density Print density is the amount of toner placed on the page, making the print appear lighter or darker. The higher the density, the darker the print looks and the higher the contrast is on the page. » Note: Remember that the print may also appear lighter on the page if Conserve Toner (Administration/Engine/Conserve Toner) is set to On. Print density is selected through a control panel menu. If the print is too dense, you can lower the density setting; if it is too light, you can raise the density setting. Menu Choices Administration/Engine/Print Density 0--Lowest density to 6--Highest density 3 Default About Gamma Correction Gamma correction is the compression or expansion of the ranges of dark or light shades in a printed image to provide the best copy of scanned images.

You can set gamma correction through the PS Executive Series Utilities or through the control panel. Menu Choices Default Notes Administration/Emulations/PostScript/Gamma Correction No--Disables gamma correction.
