Hi,
Does the white frame show in the editor when you apply the frame and when in the queue on tjh page preview? Set the page colour to black to be sure.
If not, set your "white" value to say 253, 255,255 although that should not be necessary if the white is a pure 255, 255, 255.

It is essential the white is not pure, eg. 253, 255, 255 RGB values.
You can either use as a frame with file name like Border white.frame.tif or cutout with file name as Border white.tif
The black image area in the middle must be pure black:RGB 0,0,0.
It's far better o start from scratch to make a cutout/frame. Read the Help under Features/Cutouts as to how the RGB values create transparency or not.
You do need a graphics program to do this and then convert to an image although the cutout file can be made in QU using print to file

Hello Terry and Fred:

Many thanks.
I was in fact over-complicating things by desaturating the border. Your examples have shown me the way!

best regards

Here's a QU feature if you use a cutout-frame version.
In the editor, apply the white border to an image that has no other edits. Then, in the Editor, use File, Save Current Parameters to File and make a meaningful name for the filter.
To apply the white border to a batch of images, select their thumbnails, right click and choose Predefined filter and select your white border filter.
This will then be added to all the selected images and retain any existing filters they may have.
