Chapter 2. Printing Recommendations Speed Issues Drop placement errors become apparent when printing text with serifs. The end droplets in a raster row move through the air slower than the rest of the droplets in the row. The serifs of text printed across the web direction curve up or down, depending on the orientation of the text relative to the paper flow. Figure 2.7 demonstrates the effect of high speed on fonts. Note: The arrows in Figure 2.7 depict web direction. Figure 2.7 Effects of high speeds on fonts Smiling serif Frowning serif Sans serif font To eliminate or avoid this problem, position the printheads close to the web and as defined in the hardware specifications. In addition to repositioning the printheads, consider making one of the following changes: Note: • Print the job at a slower speed. • Use a bigger point size. • Use sans serif fonts. • Avoid printing serif fonts below 8 points. • Use bold characters to help preserve the integrity of serif fonts. When possible, linearize the printer and evaluate test patterns at the speed at which the job is being printed. This is especially important for jobs being printed below 200 fpm. 2 - 8 Color Image Quality Guide
Chapter 2. Printing Recommendations Dryer Temperature Dryer Temperature Linearize and evaluate test patterns at the same dryer temperature that is being used for the job. At speeds above 200 fpm, set the dryer temperature according to the job; however, select a higher temperature to prevent creasing in the take-up roll. Color Image Quality Guide 2 - 9
