I have this image to print on a T-shirt on a Sublimation printer and I need to change  it to the RBG mode, but when I do that on de menu  Image > Mode - the colors of the image change. How to do it without changing the colors of the image?

    Hi,

    I'm sorry, but my previous answer was wrong.

     

    1. This is a Multichannel file.

     

    2. File / Open as Smart Object... "Ducky_MultiChannel.psd"

     

    3. Multichannel file are open as RGB file.

     

    4. Do Flatten Image. OK!

    Hello, move the two topmost channels to the bottom of the stack, then convert to RGB, it seems that multichannel assumes that the 3 topmost layers are CYM during the conversion to RGB.

      Thanks...It worked. The colors changed a bit because the black and the with base, the two channels moved down stoped working. But I can fix the lost workig on the layers.

        Hi,

        スマートオブジェクトで保存して、開き直すとRGBファイルになります。

        現在旅先でPCを持っていないので、日本語のままで失礼します。

        詳しい解説は金曜日になります。

            Hello, how does the image turn out? You have here an image with a white, Cyan, Magenta and Yellow layers, if I'm not mistaken usually, there is a black layer used to compensate for the ink purity (or lack thereof) and the outlines...

            Besides the channels I have a black background on the layers.

            That is how the image turns when I change the image mode.

              Multichannel is for working with the actual channels you print with, it isn’t an RGB adjustment layer. What are you trying to achieve, maybe there is another way.

                The image is to be printed on  a sublimation printer. Usually these printers works on RGB.

                That's why i need the change. Any ideia how do I do that, them?
