Digital Print | 11: Tonal Separations |

AVA Automatic Tonal is a simple method for separating tonal designs in combination with Retone to create continuous tone layers..

1. Open a tonal design. e.g.
   
 
   
2. Make sure the image is visable. i.e. a black dot inside the circle to the left of the layer indicates that it is visible. If the layers pallet is not visable Choose window > layers.
 
   
 
   
  To separate the design in to layers select the Pipette Tool from the Toolbox. Choose one of the colours and select the most saturated tone of that colour in the design and then select 'Show Add Layers Window...' from the Layers Submenu (small black triangle, top right of the layers pallete)
3.
 
   
 
   
4. In the newly opened Add Layers window, select 8 Bit Spot.
   
 
   
5. Continue creating layers from the rest of the colours in the design. The stronger the saturation of the colour, the more tones will be visable in the final separation As you create a separate layer for each colour in your design, a colour block will appear under the image icon in the Layers pallete
 
   
  Note: If the design has any white in it, you must select that as well, even if you are not going to use the layer as a separation.
   
6. When your have created as many layers as required, the design is ready to be separated.
Make sure the image is visable but not active (no pencil) and activate each new layer. Click on the pencil on the top NEW layer and drag downwards. They will become black to indicate that they are now active.
 
   
 
   
7. Choose Separate > Automatic Tonal. The Tonal window will open, showing the layer colours across the top
 
   
 
   
8. Activate the design window and pipette a range of tones for each colour chosen from the design.
   
  You need to select a wide range of tones for each layer. For example, if you have red, blue and yellow layers, you need to pipette a wide range of red tones, a range of blue tones and a range of yellow tones.
   
  The more tones of each colour you pick up the better the final tonal sepatation.
   
  Tip: Keep the colours in logical groups to make identification easier. The pipetted colours will appear in a vertical column in the Tonal window.
   
 
   
  To delete a colour from the Tonal window, click on the first percentage cell to the right of the unwanted colour chip. To choose another, hold 'Command' key and click on another percentage cell.
Then choose 'Remove Selected Rows' from the Auto Tonal action menu.
   
 
   
  Delete multiple consecutive rows from the window by clicking and dragging down a column to highlight the chips you want to delete.
Then choose 'Remove Selected Rows' from the Auto Tonal action menu.
   
 
   
9. Now click on any one of the percentage figures, then Command+A to select all.
Then select 'Set Cells to 0%' from the Auto Tonal action menu.
 
   
 
   
10. Now look at the table and see where the yellow layer meets the list of yellow tones - highlight these cells (click and drag) Similarly, look across the table and see where the red layer lines up with the list of red tones, highlight these (Command click and drag). Continue for each layer colour.
 
   
 
   
  Now select 'Set Cells to 100%' from the Auto Tonal action menu.
   
11. Make sure the image is visible but not active, and the new layers are active.
   
12. Make sure the Retone option is ticked in the Auto Tonal action menu, then click on Separate.
   
 
   
13. After your design has been sepeated, check that each mask area has separated correctly by making the image invisable and the new layers visible one by one.
 
   
 
   
  Some important tones may not have been picked up. If so, use the Pipette to add missing tones to the list. All extra colours are added to the bottom of the list. Set the percentages of the additional colours as before and repeat steps 10 to 13 to reseparate.
   
14. If areas of the design have not separated cleanly use the Mover to correct them.
In this example some of the green is on the blue layer.
 
   
 
   
15. Choose Window > Mover. By ticking in the box to the left of the green and ticking in the box to the right of the blue layer, anything you now select will move from the green layer to the blue layer.
 
   
 
   
  Select the Filled Freedrawn Shape tool and sellect the area you want transfered to the blue layer.
16.
   
 
   
  Continue until you have cleaned up each layer.
