Following aredescriptions of key elements of image quality. Note thenumbered examples on each of the test targets shown inthe right column.Office Color Image Quality1. Density of Solid Areas - Better contrast; more vivid overall images2. Line Work - Better production of lines and text3. Halftones - Better production of photographic and screened images4. Negative/Positive - Better production of fine detailPhotographic Color Image Quality5. Flesh tones - Better production of portraits6. Banding - Better solid and dithered fill7. Low Contrast - Better production of dark images8. Saturation - Better production of bright colors9. Caste – Better color fidelity10. Fine Detail – Better reproduction of fine detailsDensity of Solid Areas*Copy Density Print DensityBlack 1.40 1.43*Density is on a scale of 0 to 2.5, with 2.5 being the best possible.Copy & Print Resolution*Copy Resolution Print ResolutionVertical Horizontal Vertical HorizontalBlack 4.0 4.5 2.0 2.0*Line Pairs per Millimeter.

BERTL technicians’ measure image density and evaluatethe device’s ability to produce a full range of halftones and various sizesof negative/positive text, dots and lines in each primary printing color(CYMK).BERTL uses synthetic (photographic) test images obtained from ISOInternational Standard 12640--Graphic Technology—Prepress digitaldata exchange—CYMK Standard Color Image Data (CYMK/SCID) inorder to evaluate the ability to print photographic images.1 11 1234555567891010101010108
