Helping customers prepare
InDesign files
If you provide workstation setup and job handoff checklists to your customers, you can use this section to adapt your checklists for InDesign CS2.
Preparing customers for consistent color
For the most consistent color for both CMYK output and on-screen media, it’s best to standardize on the safe CMYK workflow, which is the default color workflow for
Adobe Creative Suite 2. This new default color workflow is designed to provide the most consistent results with the least amount of effort. Simplified administration and centralized color settings make it easy to provide your standard color settings files and instructions for customers to share across their workgroups. For more information, see “Maintaining consistent color” on page 15.
Preparing transparency
For complete information on transparency issues, see “Flattening transparency for high-resolution output” on page 57. To minimize issues with transparency, advise customers to do the following:
• Use color settings compatible with your shop’s workflow—particularly the CMYK (default) and RGB working spaces. See “Using presets and settings files to further streamline customer handoffs” on page 24.
• Set the transparency blend space to CMYK (choose Edit > Transparency Blend Space >
CMYK).
• Place Adobe native formats that support unflattened transparency: Illustrator 9 or later (native
AI format, not EPS), Photoshop 4 or later, or PDF 1.4 (Acrobat 5) or PDF 1.5 (Acrobat 6).
Adobe InDesign CS2 can flatten EPS versions of Illustrator files that intersect an object that uses transparency, but results may not be satisfactory if the Illustrator EPS file was already flattened at settings that are not appropriate for high-resolution color output.
• Use Illustrator 10 or later for best results with spot colors and overprinting.
• If pages using transparency include Illustrator 9 or 10 artwork—particularly if the artwork was saved in Illustrator native or EPS formats earlier than Illustrator 9—use Overprint Preview to verify that results will be as expected.
• When using transparency with spot colors, use Overprint Preview to monitor the results.
Customers should feel free to use spot colors with transparency, but placed files created with older versions of other graphics applications may cause issues that can be identified in advance using the output preview features.
• When applying the Difference, Exclusion, Hue, Color, Saturation, or Luminosity blending modes to transparent objects that use spot colors, use Overprint Preview or the Separations Preview palette to monitor the results more accurately, or achieve the effect using other blending modes or techniques.
• If preseparated files (multichannel or DCS) interact with objects that use transparency, convert them to Photoshop files before creating output from the InDesign document. Some Photoshop
DCS 1.0 and 2.0 files may not need to be converted if they produce the desired results. Note that Adobe InDesign CS2 can import Adobe Photoshop files containing spot channels, and multitone files (such as files in Duotone mode), but not Photoshop files saved in Multichannel mode.
