Evaluating output quality<br />

This section offers some practical advice for conducting your own output quality evaluation. Use the sample<br />

documents you created in “Creating samples” on page 11 to evaluate the print quality of the output.<br />

Evaluating print quality<br />

Individuals may perceive print quality differently. <strong>HP</strong> strongly suggests that you have several people evaluate<br />

your sample documents, in the same environment, with a consistent light source. Have them vote on the<br />

samples that they like by listing them in order from the best to the worst. Allow each person to rate the<br />

samples independently and then record the results. Also, have each person establish a “cut line” for<br />

acceptable print quality for the end-user environment. This process is referred to as psychometric testing and<br />

should be performed on all of the sample documents that you are using to evaluate text, graphics, and image<br />

quality.<br />

Look for the following characteristics:<br />

• Text should be dark, solid black, without hollow spots.<br />

• Edges of text and graphics should be crisp and smooth.<br />

• Toner should not blur or bleed.<br />

• Solid color fills should be uniform.<br />

• There should be no banding across graphics or images.<br />

• Images should be clear and sharp, without graininess.<br />

• Images should look natural and realistic.<br />

Evaluating copy quality<br />

High resolution does not directly correlate to copy quality.<br />

Copy the type of material you typically copy, whether a<br />

book, magazine, sales brochure, photograph or other<br />

high-quality content.<br />

• Does the copy quality meet your expectations?<br />

• How easy is it to adjust image quality and select output options from the control panel?<br />

• Does it take multiple adjustments and multiple copies to get good copy quality?<br />

Evaluating scanning quality<br />

Scan several documents, images, and photos.<br />

• Does the quality of the scanned image meet your expectations?<br />

• How easy is it to obtain a satisfactory image?<br />

• Is the scanning software easy to use? Are there options for scanning specific document and image types?<br />

• How large is the final scanned file size?<br />
