Hi, I have this cmyk illustration to be placed in Adobe Illustrator CS, but the layout has to be a one spot color only. I converted the illustration in Photoshop as a bitmap and save it as tif, but the quality of the illustration is not good when I place it in Adobe Illustrator, even though i make it 800 pixels/inch...I also tried to make the illustration as a monotone from the Duotone options, but when I save it as psd or tif, it doesn't want to be placed in Adobe Illustrator. How do i convert the illustration to a one color in photoshop without losing the quality, and still can be placed in Adobe Illustrator? Is there a way? Thanks so much.
