ADOBE PHOTOSHOP 6.0 193 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.
