Is there any way to put additional alpha channels into a tiff file?

We have a printer, which needs an input tiff file with 6 channels (C,M,Y,K,White Base,Super White) and unassociated tiff alpha.
We can create the CMYK images, we can rename additional alpha channels with 8BIM profile, and we know how to create the White Base and Super White channels, but we can't force imagick to store ans save these two channel into the tiff file.
Photoshop offers some tools to add alpha channels into tiff images, but we need to do this in server side.
If you have some ideas, plz share with me!
Thanks!

ImageMagick does not support extra channels in TIFF. It can support up to 5 channels (e.g. CMYKA).

Any chance that this extra channel supporting will be avaible in the nearest future?
If you have any idea to put these 2 extra channels into tiff files please tell us!
Thanks!

We do not anticipate supporting extra channels any time soon. You of course can call the TIFF delegate library directly from your custom program to add an extra channel. You can also post here if you would like to hire a ImageMagick wizard to add support for extra channels to ImageMagick.
