overprinting a grayscale tif image in ai 1

[jeffertz]

i have a placed image in an ai document and i need to back part of the image in white...unfortunately it is a gradient.

bottom line is:
i need to apply a spot color to a grayscale tif image and set it to overprint in ai (vs. 8, 9, or 10). (converting to a bitmap in phsp loses to much detail.)

does anyone have a solution for this?

Place your grayscale image, and draw a rectangle filled with the spot color, making sure it's the same size or bigger than the tiff. Bring the tiff in front, select both the tiff and the colored rectangle, and in the Transparency palette (Window > Transparancy), open the flyout menu. One of these menu items is 'Make Opacity Mask'. Select this, and then check 'Invert Mask'.

It's such a common operation you'd think Adobe would make it a little easier!

thank you very much...this appears to exactly what i have been looking for.

i don't know how i missed all those easy steps on my own.

i, also, would love it to be easier, like indesign maybe.

thanks again.
