User Guide 
Click the Auto button in the Halftone Screens dialog box to set the optimal screen angles and frequencies. Be sure to 
select Use Accurate Screens in the Auto Screens dialog box if you’re printing to a PostScript Level 2 (or higher) 
printer or an imagesetter equipped with an Emerald controller. 
Note: The recommended screen angles and frequencies for quadtones are based on the assumption that channel 1 is the 
darkest ink and channel 4 is the lightest ink. 
You do not have to convert duotone images to CMYK to print separations—simply choose Separations from the 
Profile pop-up menu in the Color Management section of the Print dialog box (for setting printer options). 
Converting to CMYK mode converts any custom colors to their CMYK equivalents. 
Exporting duotone images to other applications 
To export a duotone image to a page-layout application, you must first save the image in EPS or PDF format. 
(However, if the image contains spot channels, convert it to Multichannel mode and save it in DCS 2.0 format.) 
Remember to name custom colors using the appropriate suffix so that the importing application can recognize them. 
Otherwise, the application may not print the colors correctly, or it may not print the image at all.
