Grayscale image goes to cmyk after ripped

[pajdzn]

I have grayscale images that come out 4 color gray out of InDesign. I am using Snow Leopard, CS5, etc. I have checked the image and it is a Photoshop grayscale eps on top of a spot color screen area. I am running it as a 2 color job, the spot and black, but InDesign is converting it to 4 color. Is there a setting that I am missing? I have been doing this for over 20 years and never come across this before.

Photoshop EPS files have a tendency to complicate matters. Change it to TIFF or PSD and it should work properly.

Are you printing seps direct from InDesign - or are you creating an Adobe PDF and then separating from there? If making a PDF, what settings are you using?

Can you explain your print or export settings and general workflow steps?

Are you applying transparency effects to the photoshop image?


Best,

It could be a simple matter of icc profiles and converting to destination when exporting.

I see 2 potential problems here. Why is your image a EPS, try to re save it as a native Photoshop file. And you say your image is placed with a transparency in to of a spot color and as Screen, could be that the screen transparency wil do this (but I am not 100% shure)

Well, it appears that the eps was the problem. I tested it with psd and tif files and both worked well. The original file was an eps because it was supplied by the customer that way.

thank you for the assist, everyone.

Was there postscript color management saved with the EPS? Or was it just that it was an EPS?

It was just an eps.
