That, the link you show here, is the company I had the poor results with. One of the plastic sheet, on both side of the resist, was wrinkled and for my application the sheets were too small. I used transperent media and doubled the images. I had four layers, two for each side of the board. The results were about 70 percent of what I was looking for, but I was not expecting perfection either. I have some coming from Europe. I will update this later. The cost for me is just too high for the small amount of product.
Thanks for your input...
