color mode and raster effects resolution. New Document Basic mode; click the Advanced triangle to reveal additional options. Advanced Mode Options for Color Mode and Raster Effects resolution are found here. The default settings create a CMYK file, but if the color mode has been set to RGB, the changed settings may be easily overlooked during document creation. In an RGB document, even if the color sliders are set to CMYK when choosing a color, an RGB color is created. The document color mode can be changed from RGB to CMYK, but some issues must be corrected in the converted file. Spot-color swatches retain the correct spot-color definition after conversion, and all other content is converted to CMYK using the current color management settings. Generally speaking, this is satisfactory, with the exception of black content specified as R0-G0-B0 or 100% black, which is converted to a four-color black (rich black) when the file is converted to CMYK. This content should usually be converted to 100% black for correct output. Proof setup You can display an on screen preview of how your document's colors will look when reproduced on a particular output device. Keep in mind that the reliability of the soft proof depends upon the quality of your monitor, the accuracy of your monitor calibration, the fidelity of your monitor and output devices, and the ambient lighting conditions of your work environment. Soft-proofing mimics the appearance of printing colors on screen, but does not represent the appearance of blending modes or overprint; for that, you must turn on Overprint Preview (View > Overprint Preview). To soft-proof colors on screen: 1. Choose View > Proof Setup, and do one of the following: • Choose a preset that corresponds to the output condition you want to simulate. The default choice depends on the color settings currently in effect. • Choose Customize to choose or create a custom proof setup for a specific output device. If you have a custom profile for the output device (for example, a proofing device or a printing press), this option provides the most accurate preview of output. 2. Choose View > Proof Colors to activate the soft-proof display. You can toggle Proof Colors on and off by re-selecting the option. When soft proofing is on, the Proof Colors command displays a check mark, and the name of the proof preset or profile appears at the top of the document window. 3. To compare the appearance of multiple presets, create a new window (Window > New Window). Using the Screen Mode control at the bottom of the Tools panel, set the application to Standard mode and arrange multiple windows side-by-side. Choose a different preset for each window by choosing View > Proof Setup, selecting a preset, and turning on Proof Colors.
