   Slider	Tint In Range (non-flexo)		Tint In Range (flexo)
   	Most affected	Affects	Most affected	Affects
   Mindot	Does not appear	Do not appear	Mindot Tint In	Mindot to 25%
   Highlights	10%	0 to 25%	10% to 15%	Mindot to 25%
   Quartertones	25%	0 to 50%	25%	Mindot to 50%
   Midtones	50%	0 to 100%	50%	Mindot to 100%
   3/4-tones	75%	50 to 100%	75%	50 to 100%
   Shadows	90%	75 to 100%	90%	75 to 100%

   The value in the box under each slider is a change percentage. The graph appears flat until you make an adjustment.  Move the appropriate slider to adjust the corresponding tonal range or enter the tint out change percentage in the box under the slider.
