Dan, the whole CTP market is only about 3 years old. Given that short time frame it seems that PRST has made a lot of headway. From a Seybold report. <The CTP market really started in 1995, at the big Drupa trade show in Germany. It was stated at the time that there were probably more products working or shown on the exhibition floor than were actually working in production in the market worldwide. That is a slight exaggeration, but there were certainly a huge range of products, most of which didn't work. Most of these were targeted at the commercial marketplace for four- and eight-page formats. Let me just define what I mean. If I talk in this presentation of four-page and eight-page, or even sixteen-page format, I mean a platesetter that will image a printing plate for printing eight pages to view. For example, if you're printing on a Speedmaster 102 press, that's an eight-page-sized press. A Speedmaster 74 is a four-page-sized press. A Speedmaster 52 is a two-page sized press. So I'm using that definition in terms of size. The majority of machines being made today are for eight-page format. But the ones we saw at Drupa were predominantly four- and eight-page-sized machines. There were some larger format, sixteen-page machines, and some smaller format, but predominantly, we're talking four- and eight-page format. Most of the products that were shown at that time were conceptual products. They were not available. It was a way of putting a stake in the ground: we're in CTP, we know it's going to happen, we've got a product, and this is what we think it's going to look like. Some of the products were working. There were some that were actually being shipped. At that time, the majority of machines used one of two different types of laser. They either used an argon laser, which gives the blue light source, or they used what's called a frequency-doubled YAG laser, which gives a green light source. They are at slightly different wavelengths. The argon is 470 nm, and the frequency of the doubled YAG is 532 nm. The technology of the numbers don't mean much. The main thing is it's visible light lasers with blue or green light. At the same time at Drupa, a lot of new plates came about. Every one of the plate suppliers came out with CTP plates, if they hadn't already announced them. The other thing that came out at that show was the first real awareness in the marketplace of thermal plates and thermal plate-setting technology. This was the biggest spanner in the works for the take-off of the market, because all these companies had their new products imaging with visible light. But Creo, Kodak and Presstek were using thermal plates. I'm going to talk a lot about thermal plates later on, but basically it is a plate that uses heat, rather than light, to image it. The working beam is in the infrared spectrum, so you can't see it. It's a fundamentally different plate technology, and the majority of platesetters were not set up to do thermal technology. At the moment, the majority of platesetters that are shipping in the marketplace, are imaging with visible light, and visible light-based plates, rather than thermal plates. Current status of CTP. We have a market, particularly in North America, that's moving ahead very fast. This market started out with monochrome books and computer manuals. That sort of data was in computer-digitized form already, so computer manuals, which were largely single- and spot-color, were ideal for some of the early products for production. Business forms were another area that went fairly early, because the data was computerized. At Drupa, we saw the move to quality color. And what we're now seeing is medium and high-quality color printers rapidly implementing computer-to-plate systems. Particularly the large-scale magazine printers, who have almost wholly switched to computer-to-plate. In fact, if you want to get work from some of the big magazine publishers, you have to be computer-to-plate, and you have to be thermal. I'll discuss some reasons later on.>
