I also found that a higher contrast version looked good when a Black tone was added. Now when you apply a duotone, you will find much more control with the duotone curves. *G)* Open *Filter -> Phantasm CS Designer | Studio -> Levels.* and drag the left and right Input markers to the start and end of the histogram curve. The image should now be a pure grayscale version. *E)* Select the image (it should now be an un-clipped and un-grouped CMYK image) and select *Filter -> Phantasm CS Designer | Studio -> Desaturate.* *D)* De-select all (stages *A* to *D* were due to the file being an imported PDF). *C)* Select the image once more and *Ungroup*. *A)* Right-click (or Ctrl-click on a one button Mac) on the selected image in Illustrator and choose *Release Clipping Mask*. In between stages (*2*) and (*3*) follow these steps: This will ensure more control of the final tone of the spot image. However, I would also advise an additional initial stage to improve the contrast of the background image. In this example, I haven't set the black text or lines to overprint, which would naturally be advisable. This can be proven by viewing separations (Phantasm CS Studio tool) as shown below: This has now ensured that the background image uses only the chosen spot color. *5)* Adjust the color tone's curve in the *Duotone* window to suit - see example below: *4)* Click on the default orange color square to open the *Color Picker* and then, in this window, click on the *Color Swatches* button and select *PANTONE 158 C* followed by *OK*. *3)* Open *Effect -> Phantasm CS Designer | Studio -> Duotone.* *1)* Drop the PDF into Illustrator (CS2 or CS3 with either *Phantasm CS Designer* or *Studio* installed). I am presuming that the use of Illustrator is an option! but here's a simply solution using this software along with Illustrator CS2 and CS3. I think (hope? ) you are referring to our plugin range, **. > Also your question on converting vector cmyk art to a pantone color there is a plug in for Illustrator that will let yo do this. I realize that there may not be a good answer for this issue. There are no values in the image darker than 85%. That eliminates the shadows, because even the darkest part of the color image is simulated with a tint of black. Pitstop converts to greyscale first, simulating the color with tints of black. It has to do with the conversion process. I could just choose the image and select spot color in the Inspector, but the conversion makes the image much lighter. The remapping still leaves the other separations, so I have to delete them or remap all of them. But after the first remap, the apply button was always greyed out. I tried converting each separation, one by one. But if I chose more than one ink to remap, the Apply button was greyed out. With regard to your idea, I was able to change one plate to the Pantone color. That being said, fixing in the native application certainly would resolve the issue. It is often faster to fix them ourselves, rather than wait for a customer to fix the file and resubmit. I have a printing business and we receive many files that have color space issues. Re: Converting CMYK or RGB to Pantone colors? Are there any applications or plug-ins where you can select an RGB or CMYK image or line art and convert it to a Pantone with greater success? Thanks in advance. I thought there was a way to assign spot colors to objects in Illustrator, but maybe I'm mistaken. I thought to convert all type to outlines and then open the file in Illustrator. But I find that not all images will open with the Touch-up Object tool. I've tried using the Touch-up Object tool and changing the image in Photoshop by setting it as a monotone image. Absent that, I'm trying to find the next best workaround. If I could apply some kind of curve after the fact, that would probably work. And I don't believe I have any control over how it makes this conversion. When I convert an RGB or CMYK image to a Pantone ink with Pitstop, it ends up screening the image much lighter than I want. I realize that it is very difficult to come up with an algorithm that will examine a CMYK or RGB image and decide how to map that to a Pantone ink.
