Hi Frank, Interestingly I do not recall discussing filters. I do know there are diffusion filters on the units we have. I presumed that all options have been explored since we have had the Equipment Manufacturer out to evaluate this concern several times. The conclusion has been reached the equipment is not designed to handle double treat copper laminates and has limitations with regard to line tops less than 3 mils. They are recommending we trade in our existing system and purchase one of their laser units. Being that I have been in the business long enough to understand that an equipment salesman's job it to sell equipment, I always like to explore my options before I decide to spend money. This supplier has always treated us fairly and I really have no reason dispute the recommendations. However, I never lose sight of the fact that part of what I'm paid to do is to make decisions which insure profitability. Therefore, I must always explore options that may potentially be more economical and still produce the desired results.
