User Guide
To edit a spot channel:
1
Select the spot channel in the Channels palette.
2
Use a painting or editing tool to paint in the
image. Paint with black to add more spot color at
100% opacity; paint with gray to add spot color
with lower opacity.
Note:
Unlike the Solidity option in the Spot Channel
Options dialog box, the Opacity option in the
painting or editing tool
s options determines the
actual density of ink used in the printed output.
To change a spot channel’s options:
1
Do one of the following:
Double-click the spot channel name in the
Channels palette.
Select the spot channel in the Channels palette,
and choose Channel Options from the palette
menu.
2
Click the color box, and choose a color.
For more information, see “Using the
Adobe Color Picker” in online Help.
By selecting a custom color, your print service can
more easily provide the proper ink to reproduce
the image.
For more information, see “Choosing
custom colors (Photoshop)” in online Help.
3
For Solidity, enter a value between 0%
and 100%.
This option lets you simulate on-screen the
solidity of the printed spot color. A value of 100%
simulates an ink that completely covers the inks
beneath (such as a metallic ink); 0% simulates a
transparent ink that completely reveals the inks
beneath (such as a clear varnish). You can also use
this option to see where an otherwise transparent
spot color (such as a varnish) will appear.
Note:
The Solidity option affects only the on-screen
preview. It has no effect on the printed output.
4
Click OK.
To merge spot channels:
1
Select the spot channel in the Channels palette.
2
Choose Merge Spot Channel from the
palette menu.
The spot color is converted to and merged with the
color channels. The spot channel is deleted from
the palette.
Merging spot channels flattens layered images.
The merged composite reflects the preview spot
color information, including the Solidity settings.
For example, a spot channel with a solidity of 50%
will produce different merged results than the
same channel with a solidity of 100%.
In addition, the resulting merged spot channels
usually don’t reproduce the same colors as the
original spot channels, because CMYK inks can’t
represent the range of colors available from spot
color inks.
Adjusting overlapping spot colors
To prevent overlapping spot colors from either
printing over or knocking out the underlying
spot color, remove one of the spot colors where
they overlap.
