Forcing vector elements to grayscale

You can use CorelDRAW's Find & Replace function to convert vector elements to grayscale.

click on the image below to see the steps.

You need to launch the function twice: once for fills, and again for outlines.

Hi Toaster,

Desaturating gives the "appearance" of grayscale, but is not always the best solution for technical reasons IMO.

Why? The job might separate to CMYK instead of K only. This means uncessary film/printing plates created, or massively increased cost when run on a digital color copier.

The best route IMO is for all users to ensure that items will separate to the K plate only, no matter how they do it. :-D One thing to watch for: desaturated RGB bitmaps.

I'm sure we agree that all uses should get into the habit of either checking separation preview, or noticing how many plates will be generated based on the artwork.

FWIW... I use a macro to take care of all this stuff - since it can convert numerous bitmaps, and all vector elements in one shot. It's part of the upcoming PreFlight macro for CorelDRAW.
