14 Output quality
Evaluating output quality
Individuals may perceive output quality differently. HP strongly suggests that you have several people
evaluate your sample documents, in the same environment, with a consistent light source. Have them vote on
the samples that they like by listing them in order from the best to the worst. Allow each person to rate the
samples independently and then record the results. Also, have each person establish a “cut line” for
acceptable print quality for the end-user environment. This process is referred to as psychometric testing and
should be performed on all of the sample documents that you are using to evaluate text, graphics, and image
quality.
Look for the following characteristics:
• Text should be dark, solid black, without hollow spots.
• Edges of text and graphics should be crisp and smooth.
• There should be little or no toner scattered on the non-printed areas of the paper.
• Solid fills should be uniform and should not appear glossy.
• There should be no banding across graphics or images.
• Images should be clear and sharp, without graininess.
• Images should look natural and realistic.
Evaluating copy quality
Copy the type of material typical for your office.
• Does the copy quality meet your expectations?
• How easy is it to adjust image quality and select output options from the control panel?
• Does it take multiple adjustments and multiple copies to get good copy quality?
