Can't Batch Process-Convert CMYK to Grayscale & Preserve Spot Colors

[jack sellers]

Acrobat Pro 8.1.2 - Mac OS 10.4.11. Anyone have a way to batch process this request? I have files (many) that have CMYK images and spot color graphics. I want to convert the CMYK to grayscale and preserve the spot colors.

Spot colors are used within INDD and from Illustrator Vector images. Are you saying that Acrobat Pro 9 can batch process these to grayscale and keep the spot colors?

Thanks Jon,

Now...I go the Boss and beg for an upgrade.

Hi Jack,

Are these spot colour objects vector or bitmap monotone/duotones?

Acrobat 9 Pro is the way forward (or Enfocus Pitstop) but need more info.

Acrobat 9 Pro can now select images and convert to greyscale (leaving
pantone).

This custom fixup can be applied to a droplet and your PDFs can be
dropped onto this icon/application locally ...

However, if any images are using Pantone then it's time to use Enfocus
Pitstop for more specific conversions ...

No monies for the upgrade. I tried this with Acrobat 8 and it converts Both CMYK and SPOT to Grayscale on all four plates... C, M, Y, and K. So that doesn't work. Is there a script that does...tell " Adobe Acrobat Professional" Advanced/Print Production/Convert Colors.../ Convert all but spot colors with Profile of Gamma 1.8 and Don't Embed Profile and Preserve Black Objects?.

Jack,

Yes, that script is called Acrobat 9 as already described

Jon,

In Acrobat 9 is this conversion executed thru Preflight or Print Production?

Both - uses the same engine ...
