While CtP has been around a long time first appearing in the 1980s, it did not really come into the spotlight until drupa 1995. At that time it shared the overall spotlight of technological advance with digital printing. 1995 was when thermal CtP from Kodak and Creo burst onto the scene and spoilt the launch parties of many new green light visible CtP systems. At the next two drupas in 2000 and 2004 there were many new CtP introductions in imaging engines and plates that kept CtP well in the spotlight. Today one could say that CtP has become a mature technology with a high level of take-up in the many parts of the world. Thermal CtP has become established as the technology of choice in most areas of commercial CtP with Dainippon Screen being the market leader as the CtP engine supplier both under its own name and through a large number of OEMs. Kodak has maintained its strong position. Neither of these two companies has really introduced improved technology, just larger and slightly faster versions of their CtP engines. Heidelberg's Suprasetter, the CtP engine with probably the most advanced thermal imaging technology has substantially increased its market position and it introduced a number of new larger and faster engines at drupa.
One interesting development has become apparent recently. In newspapers it appeared there was a technological divide with violet technology being the choice of European newspapers and thermal technology being the North American choice. What we are now seeing is a split in North America where the larger metro newspapers now appear to favor violet systems with their higher speeds. Krause appears to be the main beneficiary of this with a number of large orders recently. It has also taken a very large order recently in India.
Most of the activity in terms of new CtP engines at drupa was in the violet CtP space and much of this was probably to do with new chemistry free plates from Agfa and Fujifilm. These plates are mainly aimed at commercial printers but Agfa made one major sale of these to the Austrian newspaper printer Mediaprint Zeitungsdruckerei that replaced eight old Agfa Polaris green laser CtP engines with eleven Agfa Advantage platesetters. These platesetters will image the new Agfa N92VCF chemistry free plates. Is this the first large newspaper operation to go either process or chemistry free? Among new violet CtP engines were eight-page units from Highwater, FFEI and ECRM and new four and six page units from Krause and Dotline from Germany. There were also some new European CtP suppliers coming to the show with engines that could work in thermal or volet technology. A joint development between Laser Systems Hannover (LSH) and Colenta from Austria with their Revolution 4, and from Metoda Group in Italy with their CtpOptotec range. These two companies both introduced external drum CtP engines with the choice of imaging technologies. They even offer UV exposure technology but neither could define exactly how they were going to do this but CtpOptotec states it will be available in 1st quarter 2009. This unit also had a unique feature of an interchangeable drum to allow a switch from four to eight-page format.
In the CtP plate area there were also some other new developments. Toray were showing their new Innova waterless chemical free CtP plate. Konica Minolta introduced its new thermal plate the Duros HST plate and previewed their entry into the chemistry free violet plate area with the new Replica plate.
Perhaps the main change in CtP at drupa was the arrival of Chinese CtP. This is both in CtP engines and more significantly CtP plates. Most of these new plates are thermal but there are also violet plates. In the thermal area we have The Second Film Factory of Lucky Group with its Huaguang plate, the Thermax plate from DingKaiLong (Fujian) Printing Technology, and perhaps the leading one being the FitXtra and FiteCO process free plates from Xingraphics. In the violet area The Second Film Factory of Lucky Group with its Huaguang violet plate. There was also the Marathon thermal plate from ICG-Prepress in the Uk that was designed in the UK but manufactured in China. Escher-Grad are also introducing their own violet plate into all its markets and this plate is sourced from China. In terms of Chinese CtP engines CRON thermal CtP engines from Hangzhou Cron Machinery were being shown for both newspaper and commercial applications. Beijing Founder Electronics, the leading prepress supplier in China was showing its new Eagle CtP violet engine that it sources from FFEI.
I keep the best to last with my of my highlights of drupa. This is the arrival of process free CtP that is neither thermal or violet and needs no dedicated CtP engine. VIM Technologies from Israel a company that is headed up by one of the industry's great innovators Avigdor Bieber, previously who headed up Scitex's early imagesetter and CtP applications and then was responsible for the joint effort of Scitex and KBA with the Karat DI press, introduced its new eco friendly plates. These are plates that are 'imaged' on an Epson inkjet printer. We have had inkjet imaged plates before but these either needed subsequent processing or used proprietary fluids to image onto grained aluminum plates. The new VIM JT Direct Plate is avalable in 2009 as either a polyester or metal plate and is imaged using the standard ink in the inkjet printer. This means the same printer can produce both color proofs and plates. The unique aspect of the JT plate is the coating of the plate reacts with the ink to create a dry ink receptive and water repelling surface. The new plate is still under development but is expected to be available in early 2009. Print samples from the plate however looked good. VIM is also introducing DP-S a processless metal plate for waterless printing that can be imaged on any standard thermal platesetter.

I know, that there's not a huge number of those machines out there, and presume that you didn't have time to those halls, but there were several new and faster UV machines from basysPrint and improved technology from Lüscher.
And it will be interesting to watch, what happens next in the area of waterless printing, since KBA have sold a number of Cortinas - will there be a new manufacturer of waterless plates ... or still just Toray
And what happened to the conflict between Presstek and vim.
By Jan Eskildsen on Jun 11, 2008
Now I hear, that basysPrint has sold 61 UV CTP machines at Drupa, and that Lüscher has sold 68 UV CTP machines at Drupa (until Yesterday, that is).
Not bad, compared to all the times analogue plates have been declared dead and gone by the Triumvirate.
By Yogesh Patel on Jun 11, 2008
Well then its good scenario from both basys and Luscher. After all Price matters in each way..
Good going from both the companies.

You say "Heidelberg’s Suprasetter, the CtP engine with probably the most advanced thermal imaging technology" What, in your opinion makes it the most advanced?
By Andrew tribute on Jun 11, 2008
It is certainly true the imaging of conventional plates by both Lüscher and BasysPrint is being very successful and I too hear very good sales figures for both suppliers. Both suppliers are making use of the same technology as the violet CtP suppliers with the Nichia violet diodes developed for the DVD and BlueRay markets. The difference is for UV one needs a lot of diodes to get sufficient imaging power for the plates. BasysPrint's new products shown at drupa enter the market at a lower level than the Lüscher products so it shows that there is more than just overall cost of plates pushing CtCP working. The very wide choice of plates and reliable exposure are also major selling points. It is interesting that the two new European vendors I mention both plan to introduce UV exposure options for their systems. Perhaps in hindsight Esko graphics was wrong a few years ago to kill off their Espresso UV technology that looked very promising in this area.

My comment about the Heidelberg Suprasetter is based upon its semiconductor based modular imaging heads. Each head has I believe 64 individual laser emitters on a single small chip, and each outputs a higher level of power to the plate than other suppliers technologies. Based upon the requirements of each size of Suprasetter a number of heads can be linked together to make multi-beam laser arrays using less power than competitors in a much smaller space. Also with the laser emitters being semiconductor based they should have a far higher degree of reliability. The main competing technologies use a large high power consumption multi emitter laser bar that is then focussed onto a device such as a grating light valve or optical switch to generate the required number of beams. As power is increased these devices get more complex with needs for significant liquid cooling and potential loss of long-term reliability. I am not saying that these devices don't work well, they do. I am saying that Heidelberg's technology is both more advanced and probably more cost effective and reliable.

I would like to add, that lots of concepts and new systems for entry level CtP were shown at Drupa. I counted eight of these systems, mostly Inkjet: Jetplate, G&J, TechNova, Mimaki, Kimoto,
Xanté (Laser/Toner), Mitsubishi (Laser/Toner) and VIM.
The big question even left after Drupa is: Can these systems combine low pricing with high quality ? The forthcoming installations should tell.
With regards to Agfas chemfree violet plate, I see Agfa heading for newspapers first and later to go for commercial, while Fuji is going to the market the other way round, commercial first and later newspaper. This is easy to explain, as Agfa´s - after the closure of Wilmington - without a violet CTP engine for the commercial market.
Finally a word to UV-CtP: BasysPrint and Lüscher have shown, that it is stronger than ever. With the small suppliers CtP Optotec and Brasilian Multidot (not present at Drupa) the number of UV CtP manufacturers have risen to four. And as the numerous Chinese plate suppliers ( I counted half a dozen in Düsseldorf) said. CtP is at current expensive in China - so why shouldn´t China be a natural market for UV CtP and new UV CtP-sytems from China?

There is no need to wait until 2009 to get 'process free CtP that is neither thermal or violet.' Glunz & Jensen already has an ever-growing installed base of inkjet based CtP (iCtP) devices in Europe and North America and we launched the second generation of our technology in 2007!
At G&J we use an ink developed for the purpose of plate making, and we use a grained an anodized aluminum plate specifically prepared for ink jet. We have found that the best results are achieved by using components that are designed to interact. This secures the highest image quality, better press performance, and stability over time (as we control the quality and composition of each component).
Andrew, you and everybody else can learn more about our iCtP solutions at WWW.Glunz-jensen.com
Thanks for the opportunity to comment!

Well, No one can be sure about the technology, everyday something new comes. Wait till 6 Months. One company which is already with Violet technolog is comming with 3 in One machine technology having capacity to expose Thermal , Violet and UV plates in one machine , and very fast to switch to any plate exposing , hi speed , using hi power LED.

Andy, A few comments on your perspective of the "Heidelberg’s Suprasetter...most advanced thermal imaging technology" This technology you refer to commonly called "IAB" or individually addressable beam, and is tied down by a very broad patent which was issued to HDM by the European Patent office. So broad in fact it should have never been issued. As a result others have not been able to apply the same technology in thermal CTP imaging, not that they don't have the ability, but even getting close begins to infringe the patent. Second, it's not really anymore reliable than the line illumination methods and in-fact worse with a single emmiter failure. With line illumination, one lost emitter means a slightly lower power output, but with IAB, with one lost emitter it is far more difficult to operate in a "limp mode" than with a traditional line illumination imager. To keep operating the system needs to "learn" which emitter has failed, then determine how to work without that scan line. Either only use the remaining part of one side of the array, or back-fill the missing scan with a working emitter and the data that belonged to it. As you can imagine, that is not a simple implementation. So why would anyone want an IAB solution, well in theory it can be cheaper to manufacture, so it should lower the product cost, but since only HDM can make use of it, the volume of such technology with never grow much and the cost remains rather high for HDM. Another important fact, in order to get high throughput you need multiple heads (more beams) and the alignment of multiple heads on a scan line basis means even a few microns of mis-alignment brings visible banding, so managing the system internal temperature is extremely critical since any thermal expansion or contraction in the structure which mounts the heads knocks them out of alignment.
So you are welcome to you opinion, but be aware, not all things are what they seem (or reflect reality), often they are the marketing message used to justify the R&D investment which was made and to hype the technology, which may or maynot be any better.

I would like to bring your attention to Commercial and Newspaper CtP developed by FFEI. Specially LASER developed, since Drupa, every company was opting LG or Nichida lasers for Violet engines. Fuji developed MK III Laser Pen which has NO FRINGE at all that developes 200 lpi AM/20 micron FM just like Thermal Diode. Alinte Newspaper engines are UL & EMC certified with advanced F-Theta drum, with very efficient autoloader and deloader.Commercial Model is complimented with Fuji LP-NV2 violet plates and PRO-V chemistry free plates and a job was being printed at Fuji Stall with PRO-T & PRO-V both. There was no difference between output of two. Neck-to Neck compitition is ON.

Its interesting to read this blog on printing. I would like to thank all for their contribution.
How about inkjet CTP? Does it have a bright future? I do think so. Have a look at Jetplate system...
