I use InDesign to create a newsletter that prints with black ink and one spot Pantone color [not rbr or cmyk]. I would like to be able to "paint" or highlight with that Pantone color on grey scale images. So, for example, I have a greyscale illustration of a rose. I would like to color the petals with 711C Pantone red, my selected spot Pantone color for that issue.
After hours with Adobe support in both the PS and IDD divisions, I was told it was just not posible. Whatever we tried, when the newsletter was exported to PFD for the printer, the color was no longer Pantone and therefore would not conform to the printing demand of black ink and one spot Pantone color. Anyone got a workaround?
You will need to do the coloring in Photoshop as a spot color channel. Start by making a standard saved channel in PS, then convert the channel to a spot color channel. Note that these channels overprintthe image, so you may have to adjust the image area. Place in ID as a PSD file.
