Thanks for replying
I am using Mavericks
When you mentioned Alpha channels.....
The actions panel lets you generate a lot of Alpha channels.which are then used to generate masks. Alpha channels should be discarded as masks are generated. (15 channels generated with 3 clicks) I am new to the action set and had been leaving alpha channels in the stack, Big file size!!!!!
I dumped the alpha channels from 2 problem images but left the layers intact. they saved as Tiff's and I was able to print with print tool. I also flattened them and they printed.
It s not a problem to dump alpha channels as they can easily be replaced as needed. I just need to be more tidy.....
I will try again tomorrow but that seems to be the issue
Thanks Kelly
