I once had to gestallten the product to a photo wall. This had worked fine, so I now bought back. The idea was to stick photos on wooden panels, which I tried last night and then this morning was scared. The image was blurred now, like a blurry picture, it points were many blacks, looked almost like something on Fliegenschiss. In addition, a yellow circle had formed in the picture. On a second image also this yellow circle is shown. but otherwise nothing has changed. Knew just like what happened there. Will probably try again.
