Spot function The spot function determines the shape of the dots by controlling the order in which the pels in the halftone cell are turned on. The printer code defines the order by assigning a priority to each individual pel within the halftone cell. By turning on or printing a portion of the pels within the halftone cell and then combining the different halftone screens, your printer is able to print millions of colors. Image Smoothing You can turn Image Smoothing on from the graphics tab of your printer driver or through the PostScript Menu using MarkVision or the operator panel. This increases the contrast and sharpness of bitmapped images and smooths color transitions. This setting is useful for images downloaded from the World Wide Web at 72 dpi. The setting has no effect on images downloaded at 300 dpi resolution or higher. Printing text In both PostScript and PCL emulations, 100% black text prints using black toner (K of CMYK). This results in sharp, crisp text characters. The printer applies a unique screening algorithm to small text (less than 24 points in size). This helps ensure that small point size text has smooth, crisp edges. 31
