Hi All,
I'm working on a piece that's going to be printed 2 color. Pantone Black and 396. I've got a black and white image with a graphic in 396 overlaid on top so that the bkg is showing through. When I try to make this image a duotone in photoshop, it gives the whole image a tint of the 396 instead of just the area where the graphic is. Anybody know how to accomplish this? Or should I do it all in InDesign with just a monotone image and then overlay the graphic and set it to overprint in Indesign. That probably wasn't clear at all, but I'll give it a shot.
Please help!

try adjusting the curves in the duotone dialog box.

thanks baseline. am i basically adjusting so that the 396 doesn't show in the black and white image and just on the graphic that is on top?
- im not sure i follow. whats the desired effect?baseline_shift

duotone means mixing black with a 2nd ink to achieve a greater range of midtones. often done with black and a 2nd neutral or subtle tint color, even grey. 396 is not really a good choice for duotone.
sounds like you want an overprint effect. select overprint in layout or if its a photoshop piece create a 2 chanel spot image.

2 channel spot image?
- inkpink0
i myself would create that as a 2 channel spot image.
color 1: black, with lightened area for 09
color 2: 396 overprinted inside the 09

how do i tell photoshop though that i just want the 09 to be overprinted in 396 and not the whole image? sorry, i kinda suck at photoshop.

photoshop>channels>new spot channel>select your pantone
if its a 2 color job you have to do it that way.
or place your greyscale image into a layout app and create the effect with over[printed vectors
- make sure your printer is ok with it if you choose the second option here.baseline_shift
- and with something like this, proofs are your best friend. talk to your printer.baseline_shift

thanks to you also baseline. I've decided that i'm going to do it with a grayscale image and then use the 09 as a vector graphic. do I just set the 09 in indesign to overprint? or would you put some transparency on the object too?

If you overprint the color, your lightest color (aka, white) will be the solid color. That's not like the image you showed above.
- overlay?monospaced
- inkpink is right, no effects
DEFINITELY go to press with this and oversee productionmonospaced

sorry, mono... not following you
- inkpink0
ah shit. sorry mono is right... i didn't look closely at the image. whites are coming through. overprint not gonna work as per image. transp>multiply will simulate overprint result.
sorry you'll have to dick with it in PS. not an easy effect with 2 spot colors. almost like a duotone inside a greyscale image. or save out 2 grayscale images, layer and add color to the tiff in layout.
- guess i got ahead of myself when i posted before your image came up. sorry again.

i'd still try an overprint 09 yellow ontop of a lighter 09 in the greyscale image.
not going to be the exact same effect, but a lot less complicated and more predictable off press.
better to simplify for spot color print. think like screenprinting. do tricks that take advantage of the process. overprinting is reliable and can be used very effective.
