Colors changing when exported to pdf in indesign

[claraagps]

I'm trying to export my work in indesign to a pdf and the colors of the images always change. The images were made in photshop and are linked to the file, the shape (that looks like a star) was made in illustrator and it didn't chage colors... The first picture below is part of the work in indesign and the second is part of the export pdf. When exported to jpg and epub the colors stay the same. I need my work on pdf, can anybody help me?

1. What color space do the pictures have?
2. What color output space does the PDF have?
3. Did you turn on CMYK proof preview in Photoshop? You should do it when you design for print and the images are in RGB.

Hi, thanks for the answer :))

1.  I m using CMYK in the photoshop 

2. I tried exporting in RGB and CMYK, and both looks the same 

3. The file is on CMYK , I hadnt tried to change the proof preview, but i have tried now and when exported the colors still change...

Thanks in advance!

Hi @claraagps , Is your Transparency Blend Space set to Document RGB or Document CMYK? And what are your Export>Output settings? Show a screen capture of the Output panel if you can.

I think it's more about bottom images going Cyan?

@claraagps

How did you color them? Are they like that in Photoshop? Or are they B/W or Gray and you colored them in the InDesign?

Hi, thanks for the answer :))

I colored the images in four different colors (orange, red, magenta and cyan), all the pictures turned either magenta or cyan (there are even some that were magenta and turned cyan).

I colored them using photoshop: Image > Mode > Grayscale and Image > Mode > Duotone. 

1. exported as jpg

2. exported as PDF 

Thanks in advance!

@claraagps

So they are essentially Grayscale - with some effect applied in Photoshop?

Can you save them as Grayscale - and do coloring in InDesign? 

Use Direct Selection Tool - select color - you'll be coloring black pixels.

hi @rob day , thanks for the answer!

The Transparency Blend Space is set to Document CMYK. 

Here is the settings when exporting: 

Thanks in advance!

Does it happe if you set your transparency blend space to RGB? With Interactive PDF exports all color gets converted to RGB with an embedded sRGB profile—the RGB blend mode could affect color on an RGB export. Usually you would get a warning:

If ignore the warning I get this:

Hi, everyone

I saved all the images again as png and relinked them in indesign and it worked! 

Thank you all for the answers!!

Hi @claraagps , Also, the PNG format does not allow CMYK color, so it is likely the forced conversion from CMYK to RGB is the reason for the changed Export color.
