Test the appearance of your greyscale photographs for any particular emulsion / toner combination by making digital approximations, or ‘nanchate’ prints of the final product.

note: nanchate (nan-cha-tay) is Japanese for imitation or fake

Make test Cyanotype prints or Van Dyke Brown prints with a Colorize Strategy, or use Duotones to make multi-tone tests such as Tea Toned Cyanotypes, or Cyano-Dyke prints.

 
         
the COLORIZE STRATEGIES (for single-color emulsions)    
NANCHATE CYANOTYPE      
  Use the Colorize technique to render the picture Cyan, then adjust the density with a curves adjustment layer (if necessary). It may help to add a little bit of magenta to make the color more blue.
 
click on foreground color box in the toolbar
  the color picker window will open
create a color that is close to the Prussian Blue of Cyanotype
  set Cyan to 71
  set

Magenta to 21

  set Yellow to 0
  set Black (K) to 0
 
   
   
 
select the image layer (not any adjustment layers)
fill the picture using edit> fill        [cmd] f5
  use foreground color
  set

mode to color

  use 100% opacity (default)
 
   
 
     
NANCHATE VAN DYKE BROWN    
  Use the Colorize technique to render the picture Brown, then adjust the density with a curves adjustment layer.

click on

foreground color box in the toolbar
  the color picker window will open
create a color close to the dark brown of a Van Dyke Brown print
  set C = 63, M = 71, Y = 71, K = 83
 
   
   
 
select the image layer (not any adjustment layers)
fill the picture using edit> fill        [cmd] f5
  use foreground color
  set

mode to color

  use 100% opacity (default)
adjust curves with an adjustment layer
lock the top 3/4 highlight level to 191:191
pull the 1/4 shadow level down less than normal 64:48
 
       
       
       
the DUOTONE STRATEGIES (for multi-process prints)    
TEA-TONED CYANOTYPE      
  Tea toning will add a yellowish highlight to a cyanotype, and reduce the cyan blue to a navy blue.
The best way to achieve this color split is using Duotones.

or build your own:  

set the first color

to black
  adjust the curve to only appear in the shadows
set the midle color to a dark Prussian Blue of a Cyanotype print
           C=100, M=64, Y=19, K=3
  adjust the curve to appear in the midtones and shadows
set the third color to a soft Tea-Stain Yellow
           C=9, M=19, Y=78, K=0
  adjust the curve to appear mostly in the highlights
  subtle adjustments in the curves can make a big difference
  the color of the brightest highlight can be from almost white to a darker yellow
  the amount of overlap of the colors creates intermediate colors
  the amount of black in the shadows should be minimal, but…

BLUE VAN DYKE COMBO      
  Make a slightly out-of-register Van Dyke Brown print over a very over-exposed Cyanotype
to achieve this dual-emulsion effect.
