But I can't find the way to properly export it as CMYK with that same transparency involved. Make sure that “Transparency” is selected as the background and not “Artboard.” Artboard will give you a white background. When it is converted to PNG it seems the background is filled to white. So i save these images as .png in GIMP and the transparency is exported with it.
if you are a Graphic Designer Advertisiser, Website Designer or Web developer, then you can easily get benefit from this site .
If it happens because of RGB bitmaps with transparent background, which I suspect it is, changing from CMYK to Native will prevent the RGB bitmaps from being converted to CMYK on PDF export, and hence they will move on to the RIP and affect the printed result. For some processes, it is useful to have all channels in separate images.
I am having trouble converting a cmyk tif with background transparency to rgb. As you can see in the attached image, transparency is lost when saving as TIFF.
Open an image with transparency (for example "Ducky.tif") with Graphics Mill for .NET.2. Step 6. Dmitry, you're absolutely right about the channels. The saved TIFF image DOES have a channel with alpha data.

This file is loaded correctly by different imaging software - e.g.
I think I'm seeing a problem with a CMYK PDF that has a transparent background. © Copyright 2012 KDE Community Forum Team. I'm testing against 7.0.1-0 but I think it also affects the 6.x branch.
Select the transparency preferences you prefer. Resize, convert to different color space or do nothing.Everything works as expected except saving the image as TIFF with transparency. I create CMYK image with alpha channel by Graphics Mill for .NET, save it to TIFF, then load it by Photoshop, convert in to RGB in Photoshop and save it to TIFF.
I loose the alpha channel whenever I save as TIFF, regardless of color mode (RGB, CMYK or GrayScale).
I also found it when looking under the Channels tab i Photoshop. Save the file as a PNG.
Sorry, I was very unclear. tiff or jpg do. All rights reserved. So we have RGB TIFF file with alpha channel. Select "Layer Via Cut" in context menu.
I create CMYK image with alpha channel by Graphics Mill for .NET, save it to TIFF, then load it by Photoshop, convert in to RGB in Photoshop and save it to TIFF. i tried to save a Aurigma RGB Image with transparency as a cmyk image.Unfortunatly, the transparency displays as white. If so, choose Image/Separate Image and choose the "Create separate separation from the alpha channel" in "Alpha Options". However, I cannot get Photoshop, InDesign or MS Office Document Imaging to recognize it as an alpha channel.
Step 5.
Go to channels palette and select RGB or CMYK channels (the first channel), then click with CTRL on alpha channel.
After that choose Magic Wang tool and left click on image.
I think the only file format that supports cmyk is tiff -- have you tried saving as tiff instead of png? it seems png doesn't support cmyk, i didn't know that. Step 4.
After the conversion it appears the black values are off and when opened in photoshop the visual is strange. Then you can save each separation layer separately using "save layer as image".
by Windows Picture and Fax Viewer.Which operations do you want to perform using CMYK images with alpha in Photoshop?1. Instead there is a new channel called "Alpha 1", but neither Photoshop nor InDesign recognize it as transparency. This file is loaded correctly by different imaging software - …
I don't know why they do it but all my tests show that they do.
