PhotoShop grayscale images

[Jasonm]

Don't flog me if this is not the right place to post this.

We are taking a PDF and forcing it open in PhotoShop flattening it then converting to grayscale and saving that as a JPG. (the DPF was created in InDesign)

Our mailing guys are using a program called New Leaf to bring this in so we can do some variable data printing. When they save out the PDF, it's showing up as having RGB in it. They are telling me that this program (I know nothing about it) only outputs what it was given and that PhotoShop it not making a "true" grayscale image.

Has anyone heard this before, as it's a new one for me?

Thanks in advance!

if your going Image-mode-greyscale...... there should be no reason it wont be. This is your last process before saving?

Have tou tried saving as a tiff? It shouldn't make any difference, but it might?

[Jasonm]

Yep image mode grayscael....the problem is the other program NewLeaf (from what they tell me) will not work well with tiff. I could try a bitmap now that I think of it.

have you tried copying and pasting it to a new document, then resaving?

save a greyscale eps - pdf, what does the software work with, since we've agreed what it doesnt like (tif)

if I understand correctly, the mailing guys are saving it into PDF's Right? If so the distiller settings might bet set to 'convert to RGB.' Some keep the settings 'leave color unchanged'

FYI, if you open an PDF in Photoshop, it is called rasterizing it. You can select greyscale at that point and then flatten the layers

I hope this helps
