Problem with TIFF

[dkatsman]

Hi there.
We are using the Image Magick to generate a non-rectangular image uploaded by user on a website.
The website module generates a transparent area of the certain shape around the uploaded user's image and generates the TIFF file.

This images are being used for futher printing in on EPSON SC-7000 via Wasach SoftRIP TX.

The problem is that transparent area around the image becomes black, which terrible for us )
JUST AN IDEA. It seems to me that the generated image has multiple layers and RIP software doesn't "allow" it and shows me a black area.

My qusetion is how can i make sure that generated TIFF has merged layers?

Here is the screenshot: http://joxi.ru/GrqBvqpiO1BYmz
the left one is after re-saving in Corel
the right one comes directly from Image Magick (has black area around)

Please give any other ideas.
Thanks in advance

So, you have code that makes some pixels transparent.

You must also have some code that is making those pixels opaque. Is that the problem you want to solve?

You think that the solution is to make a second layer instead of making pixels transparent. Well, you can do that of course, but without knowing more about the problem I can't know if this is a solution.
