• Font Types Not Allowed: Check for protected fonts (fonts which cannot be embedded in PDFs), bitmap, TrueType, ATC (Adobe Type Composer) fonts, and several different Type 1 and OpenType formats. • Non-proportional Type Scaling • Minimum Type Size: Set a minimum type size. You can also limit the error reporting to white or multicolor text. • Cross-References: Check for out-of-date or unresolved cross-references. • Conditional Text Indicators Will Print: Check for Conditional Text whose indicators are set to print. Document • Page Size and Orientation: Check for document page dimensions (ignoring orienta- tion prevents flagging of document based on portrait/landscape orientation). • Number of Pages Required: Set options for minimum/maximum number of pages, as well as exact number of pages, and multiples of a specified number. • Blank Pages: Specify whether pages are considered blank if they contain only master items (and no other document page content), or if they contain only non-printing items. • Bleed and Slug Setup: Set a minimum/maximum or exact value for bleed amount and slug area size. To modify an existing preflight profile, select it in the Profile pop-up menu in the Preflight panel, and then choose Define Profiles from the panel menu. Click OK when you're finished. Choose Preflight Options from the Preflight panel menu to choose whether to embed the working profile into new files, whether to use the embedded profile or your working profile when opening new documents, whether to include hidden and non-printing layers, and whether to check objects in the pasteboard and objects set to be non-printing. There are some font issues that Preflight does not catch: Fonts required by any PSD files with text layers are not indicated in the list. These fonts will not be checked for by preflight, nor will they be included when the file is packaged, so the customer will have to manually collect them for job submission. Suggest that Photoshop files containing text be saved as Photoshop PDF, which embeds fonts and makes packaging fonts unnecessary. In addition, text in a Photoshop PDF will print as sharp, vector edges, whereas text in a Photoshop PSD will be rasterized during print. Finding Problems: Additional Forensic Tools Whether you use InDesign's Live Preflight function or dedicated preflight software, or rely on experienced prepress operators to carefully examine incoming files, it's important to recognize problem files early in the production process, in the interest of saving time, money, and sanity. For a thorough analysis, use all the forensic tools available to you-Separations Preview, Overprint Preview, Flattener Preview, and the Info panel-in addition to the Preflight function. Separations Preview Use the Separations Preview panel (Window > Output > Separations Preview) to evaluate on screen how a document will color-separate on printed output. You can view individual spot and process color plates or any combination of plates. Choose an option from the Separations panel menu to view plates in their actual ink color, or as black. You can also highlight overprinting objects and areas that exceed a specified total ink limit, by choosing Ink Limit from the Separations Preview panel's View pop-up menu. If you need to make adjustments, for immediate feedback you can edit while Separations Preview is in effect. Adobe InDesign can preview separations by displaying any combination of the inks defined in the document, such as the cyan plate and the magenta plate. The results display using highresolution screen display engine in InDesign to more realistically represent conditions such as overprinting, RGB-to-CMYK conversion, and spot color interactions with transparency. Trapping, however, is not simulated. The ability to display overprints and ink limits for any combination of plates can make the Separations Preview capability more useful for evaluation than a laser-printed separations proof. Separations Preview is calculated using the ink characteristics for process and spot inks. Adobe Creative Suite 4 Printing Guide 35

Finding Problems: Additional Forensic Tools
Whether you use InDesign’s Live Preflight function or dedicated preflight soſtware, or rely on
experienced prepress operators to carefully examine incoming files, it’s important to recognize
problem files early in the production process, in the interest of saving time, money, and san-
ity. For a thorough analysis, use all the forensic tools available to you—Separations Preview,
Overprint Preview, Flattener Preview, and the Info panel—in addition to the Preflight function.
Separations Preview
Use the Separations Preview panel (Window > Output > Separations Preview) to evaluate on
screen how a document will color-separate on printed output. You can view individual spot
and process color plates or any combination of plates. Choose an option from the Separations
panel menu to view plates in their actual ink color, or as black. You can also highlight overprint-
ing objects and areas that exceed a specified total ink limit, by choosing Ink Limit from the
Separations Preview panel’s View pop-up menu. If you need to make adjustments, for immediate
feedback you can edit while Separations Preview is in effect.
Adobe InDesign can preview separations by displaying any combination of the inks defined in
the document, such as the cyan plate and the magenta plate. °e results display using high-
resolution screen display engine in InDesign to more realistically represent conditions such
as overprinting, RGB-to-CMYK conversion, and spot color interactions with transparency.
Trapping, however, is not simulated. °e ability to display overprints and ink limits for any com-
bination of plates can make the Separations Preview capability more useful for evaluation than
a laser-printed separations proof. Separations Preview is calculated using the ink characteristics
for process and spot inks.
