hey guys, im sure i know this already but i have had a complete mind blank... any help would be awesome.
I have a cmyk document and i want to overprint a red on top of one of the images in indesign cs2. Does the red HAVE to be a spot colour?
Sorry for the idiotic question.
cheers

If you want it to be a fifth (SPOT) color on the press, YES. If you want to keep it economical you can make a CMYK red mix and drop it on there.

Ok cool, yeah ideally id like to keep it 4 colour, but i cant see how to set the red up to overprint in indesign cs2.
Hmmm

If it's all CMYK there is no overprinting needed. It's all mixed into the CMYK breakdown.

Ahh i see. I dont think ive explained what i want. I actually want the red to overprint the image so the image can be seen through the large text. Will that require the red to be a spot? or is it possible to do it process?

It's called PhotoShop.... CMYK mode. Layer the red over the image and change the opacity so you can see what is below. Or do an overlay layer. or or or.....
If you need more I'd buy a book or go talk to a printer so you can get some hands on experience.

Yeah cheers. I know you can do it in photoshop. I need to do it in indesign. Anyone else help me?

I think you can do this in InDesign by creating the object or text in your red color, then by setting it to multiply in the drop down menu within the transparency palette.

transp/ multiply

Ahh ok cool, so you are kind of representing what a proper print overprint would look like? Great, thanks for that Josev.

or there's an overprint checkbox somewhere i'm sure - same as AI - can't remember where now.

so Attributes/ Overprint fill.
then use View/ Overprint preview to see results.
better practice to use overprint settings instead of transparency.

Horton, thats exactly what i need.. and im guessing it doesnt need to be a spot colour either?
- yup CMYK values are OK..horton
- its basically just telling ID to not knockout a white space behind your red object...horton
- the CMY are inks are all transparent so not an issue of which plate prints first.. if that makes sense.horton
- just be carefull of ink overload.. 100M + 100Y overprinting large areas of near 100K is pushing it.horton
