Whenever I try to blend an image to an artboard - i get the conflict shown below on artboard 3. However I started a new document with a transparent background and it blended properly as shown on artboard 1 ...added new artboards and the blending problem returned. How do I make artboards blend friendly ?
So this is only half an answer, but hopefully something that will help you.
The 'better' way to put an image over something like text or shape is using a clipping mask. This method is generally better because it leaves clean edges around the text or object whereas using a blend mode can affect objects/text around the blended object as well.
To use a clipping mask:
- make sure the layer you want to blend over text/object is on top of the text/object.
- Right click on the top layer and select 'Create clipping mask'
When using this method I do not have the problem you describe in your post so hopefully it will also accidentally solve your problem.
