22 Evaluating color laser printers
Evaluating print quality
When you evaluate the overall quality of an output, avoid magnification. Under magnification,
insignificant differences become huge. However, a detailed inspection is still necessary, and when
doing this, look for the following characteristics:
Text print quality
• Text should be dark, not faded.
• Text should be solid black, without hollow spots.
• Edges should be crisp and smooth, not jagged, or with stair-stepping.
• Portrait and landscape text should have the same print quality.
• Toner should not blur or bleed.
Graphics quality
• Edges of colored shapes and graphics should be well formed and smooth.
• Solid color fills should be uniform.
• There should be no bands across graphics.
• Areas of solid black should not bleed into areas of solid colors.
• Areas of solid toner should not wick into the paper fibers.
Image quality
• Images should be clear and sharp.
• There should be no bands across images.
• There should be no graininess or visibility of dots.
• Skin tones should look natural.
• Images should look natural and realistic.
