How to Use Indesign Separations Preview

Excerpt:

[With the Separation Preview] you can avoid unexpected spot colors, overprints that don’t overprint, overprinting where you didn’t want it or CMYK blacks in text and placed files. Simply put, this will allow you to see how your job is going to separate and how the colors will print on a press.

Pick Your Scanning Resolution

with scan calculator at bottom of page

 IMAGE RESOLUTION

300 ppi (pixels per inch) is sufficient for printing at 133-150 line screen [on coated paper]. Higher PPI may be needed for high line screen (175 lpi or above).

[Uncoated paper: LPI = 133, PPI = 266]

Consult with the PSP (print service provider) to determine proper resolution for your job

Information from Assorted Books, Articles (paraphrased)

Native File Formats

Designers no longer have to rely on EPS or TIFFs, but can send in Adobe Illustrator or Photoshop files, or send AI or PSD files in page layout software (such as InDesign)

Trapping

The printer, not designer, should handle all trapping

Digital Printing v. Offset Litho

More print shops today are using digital, or in addition to offset litho.

Paper choices for digital tends to run smaller. Leave spot colors as Pantone – don’t bother converting them to process colors (i.e., CMYK).

Color Space

More printers today are able and willing to accept a RGB workflow vs. a CMYK. Ask your printer if they prefer RGB or CMYK

DCS is no longer being used – or not as much

You don’t need to use DCS for spot color channel capability. Put spot color channel in Photoshop, and put the Photoshop native file in InDesign and export as PDF

Transparency

Adobe Illustrator and InDesign do not handle Photoshop blending modes well.

Solution: create the drop shadow in whatever app you are using (for example, use AI to create drop shadow in AI)

General Information

Resolution and LPI

Coated paper: most linescreens are 150 LPI, so an image resolution of 300 PPI is sufficient

Uncoated paper: most linescreens are 133 LPI, so an image resolution of 266 is sufficient
