Converting select pages to greyscale in Publisher

Recommended Posts

Hi stutes,

We can't convert a page to grayscale, you could convert the whole document.  I guess one way would be to create a separate grayscale document, save it and then use File>Place to bring it into the main document.  But when you Publish as PDF I don't how that would be treated.

You could apply adjustments to the page, such as an HSL layer to desaturate colors.

In Publish, Is there a way to convert select pages of a color document into greyscale?

I would publish two versions, one color and one gray. Extract the pages needed from the gray version and replace the corresponding color pages. You would just need any pdf editor capable of removing/replacing the pages.

Given that the overall document is still color, won't the grayscale pages you insert into the color document also end up as color pages, albeit gray?

How is that different from desaturating a color page, in the end?

(If you can't tell, I find the concept of different color settings for different pages within a single color file confusing :) )

That's what stokerg suggested but with one caveat: "But when you Publish as PDF I don't how that would be treated."

The Black & White adjustment generates K only output. For image resources you could use the "K only" button, which will convert RGB resources to grayscale in 4c and reduce CMYK resources to their K channel only.

Another option would be to export the file or specific pages as grayscale PDF and combine the wanted pages of the resulting PDF with that which should have colors.

The is a two-page spread. I converted just the recto to grayscale. If inspected in pitstop/acrobat, it is indeed all on the black plate.

Thanks for all the suggestions everyone. I'll give them a try next time I need to print a document that has both color spreads and greyscale spreads (in the next couple of weeks).

If you wondering why, it boils down to cost. Our in-house copier has a contract that charges more for color copies (to be expected). But when I print, I can set the driver for the color quality to "Auto", which detects if the pages/spreads have color on them or not, and if not, it prints in black and white... and in turn costs less. This even holds true for pages/spreads within the same print run. So, to keep costs down, I print the cover spread in color, and the rest of our booklet in black and white.

My current workflow involves exporting to PDF and converting the inside spreads to greyscale using Acrobat Pro. And that works quite well. Just looking for non-Adobe options.
