Got a slight problem, sending a job to print as a two colour job, however when creating the duotone images in Photoshop I have no idea how to set them up so that the white of the paper can come through on certain areas?

So the images are duotone, but there are 3 colours, a,b and the paper colour?

help!

Assuming you are starting with a greyscale image, why can't you adjust the levels to increase the white areas? Or have I missed the point completely?

Duotones only set the colours usage not the paper. If you need to specify a third colour you need to set the document up as a tritone.

hmm, im starting with a duotone, so two colours are getting printed, but I also want to leave areas where the white of the paper will show through (quark).

When you change an image to a duotone, all the white immediately changes to one of the spec. colours I have chosen for the duotone...

does this make sence?

:there are only two colours getting printed but I want areas of 'paper colour' showing through in the duotone.

Whenever I have needed to use an image as a duotone I converted it to a greyscale and then specify the colours as a duotone - leaving all the white space from original image.

Can you attach a sample of what you are working on?

cheers, think its been resolved now, I was asking for a couple of the guys in work.

They were making it wayyy more complicated than it was

If you are printing using two spot colours then surely you can use duotones (two plates)?

Im no exper on this as you can tell, so any reading would be appreciated

duotone is black and one pantone.

Mik · 22-05-2006, 12:33

do it in photoshopo, then place in quark - cut out shapes as .eps (which are white) place on top of image.

bobs.

Duotone is a mix of any two colour tones - hence the name duo-tone!

Not sure where to read up on this stuff, I've only learnt from bitter experience. As you pointed out yourself, two colour print is actually the two colours plus the paper colour. DUOTONE is not really a printing method as such - and good luck getting it back from the printers looking anything like what you saw on screen when you designed it. Notice Duotone is merging the two colours... print does not work like that.

If I were to use photoshop for a two colour job (and I wouldn't, I would use illustrator) I would delete the CMYK channels and add my two spot colour channels, then save it out as a Photoshop EPS.

haha, this is a great example of why Duotone is a bastard.

To help you predict how colors will look when printed, use a printed sample of the overprinted inks to adjust your screen display.
