Então DA men??
É assim, essa cena do CMYK acho que é para quem trabalha com impressões em gráficas.. pelo menos é o que sei quando vou falando com algumas pessoas que fazem uns flyers, daqueles grandes..
Neste caso, a máquina de revelação que falo, é uma máquina que revela os 35mm analógicos a cores e mesma máquina revela também fotos digitais.
A cena do Cyan Magenta Yellow e K(??) é para essas máquinas das gráficas, que trabalham com essas cores de base.. agora as tais de revelação de fotos a químicos, acho que não são com essas C M Y K.
A questão da gestão de cores, tá muito relacionada com as impressoras.. a dica que eu falei, também é válida para se gerir as cores antes de mandar imprimir numa impressora Canon com o papel xx.. Olha, o exemplo do DeviantART, se quiseres lá colocar um PRINT de uma imagem, deves usar o file ICC que eles facultam, para que as cores depois na impressão final que eles fazem, estejam o mais correctas possível.

Where can I get the ICC Profile (Color Profile) for prints?
You can download it here.

Using our ICC Profile to Soft Proof
If your monitor is properly calibrated, you will be able to use the ICC profile downloaded from our site to see what your prints will look like on our printers. The prints should be identical, regardless of what size print you choose to order.
To do a soft proof in Adobe Photoshop, follow these simple instructions:
* Make sure you have the profiles installed. If you did the installation while Photoshop was running, please exit and reopen Photoshop.
* Make sure that you are working in the sRGB workspace in Photoshop. Our printers make color adjustments based on the assumption that your file is sRGB (the standard color space for most digital cameras). To set sRGB as your workspace, go to Edit > Color Settings... and select sRGB from the dropdown menu next to RGB. If your image is CMYK, you will need to convert it to RGB. We require that the files uploaded to us be RGB.
* When you are ready to see what your image will look like when it's printed, go to View > Proof Setup > Custom... A dialog box will pop up. On the Profile dropdown, select either deviantprints.icc or fujicrystalarchive.icc from the list. Make sure the Preserve Color Numbers checkbox is NOT selected and click the Preview checkbox if you would like to preview the proofing. Select OK to make adjustments to the photo while the soft proofing is enabled.
* To turn off the proof, go to View > View Proofs and uncheck it. This will return your view to the native sRGB."
Olha... eu acho que o problema é que o GIMP não trabalha com CMYK. Tem um plugin por ai que faz ele trabalhar com CMYK. Dai você converte a escala de cores e depois sim mexe na imagem e manda revelar.
