          To assign a different default spot color screen angle, select a
        
        
          color in the list.
        
        
          For IS screening, Prinergy cannot assign the

            Cycle Through Screen Angles
          
        
        
          Select this option to assign default spot color screen angles
        
        
          cyclically to the available process colors, in CMYK order.
        
        
          Prinergy does not assign process colors that have already been
        
        
          used to screen a spot color.

            Screen #10
          
        
        
          .
        
        
          For IS screening, Prinergy cannot cycle through angles other
        
        
          than CMYK.
        
        
          
            Do not increase yellow ruling
          
        
        
          To reduce moiré, the AM screening algorithm provides yellow
        
        
          screen frequencies (lpi) that are up to 14% higher than the
        
        
          cyan, magenta, and black screens. If you want a Y screen that is
        
        
          more similar to the Y screen in Prinergy 2.2 and earlier, select
        
        
          this check box. It limits yellow screen frequencies to between
        
        
          -4% and 4% of the ruling of the C, M, and K screens. For
        
        
          example, if the C, M, and K screens are at 150 lpi, this check box
        
        
          limits the screening algorithm to providing a Y screen between
        
        
          144 lpi and 156 lpi.
        
        
          This setting does not affect the yellow frequency of an IS screen
        
        
          set. To change the yellow frequency of an IS screen set, use the
        
        
          IS Screen Set Editor.
        
        
          
            Rotate Screens With Pages
          
        
        
          Select to rotate screens with reader orientation for each page in
        
        
          an imposition.
        
        
          When some pages are rotated 90°, rotating screens with the
        
        
          pages allows all pages to be screened at the same angle.
        
        
          Screens are only rotated at 90° so pages that are oriented at
        
        
          other angles are not affected. The result of rotating screens is
        
        
          apparent when you screen with dot shapes that are not
        
        
          rotationally symmetric, such as Elliptical and Line.
