Analysis of Application of Three Major CTP Technologies in Newspaper Industry (I)

According to Ifra, as of October 2003, before the Ifra 2003 (International Press Technology Association) held, the global newspaper CTP installed capacity was 1700 units, compared with the time of Ifra 2002, the growth rate was 27%, and the new installed capacity was Two-thirds are in Europe. The future newspaper system will use the three major technologies of thermal, violet and UV traditional plates; the original leading visible light system will begin to shift to the violet laser system; the range of plates for the three technologies will continue to expand; some new ones will be introduced. CTP is mainly for the low-end market. In general, the newspaper CTP has special needs, which are different from commercial printing and packaging and printing CTP.

Thermal, violet laser, CTcP three major technologies

In recent years, there have been disputes between photosensitivity and thermal technologies in the field of CTP. The emergence of new photopolymerization and higher power diodes has enabled Violet Lasers to join the thermal and UV technologies in the newspaper CTP market. The status. Due to the superiority of the violet laser CTP technology, there has been a shift toward violet laser technology in the visible light CTP field. The launch of two new purple laser versions from Agfa and Fujifilm has also added impetus to this process, and even determined thermal advocates are considering entering the CTP field.

Violet Lasers At present, no manufacturer other than Agfa has provided silver salt plates to the market. Kodak Polystar is considering providing a violet laser plate. All new developments, whether violet or thermal, will focus on polymers.

Although violet lasers have a strong driving force for development, they are also limited by a number of factors: 1 Not all existing green laser systems are suitable for violet laser conversion, and the transition to violet laser systems only occurs when alternative or extended purchases are made. Situation; 2 Even with the current 30mW diodes, the imaging speed of the photopolymer-based violet laser system is 10% to 15% slower than the silver halide-based green laser system. This situation may change due to the presence of more powerful diodes; but there are concerns that these diodes will be used in commercial printing systems first before they are applied to newspaper systems. It has also been proposed to overcome the lack of speed by increasing the sensitivity of photopolymerization, but this is unlikely to happen in the near future.

Thermal The thermal technology powered by Creo and Kodak PolyVision has seen substantial gains in terms of market share. In recent years, the introduction of FUJIFILM has also provided additional impetus, not only to avoid the user's concern about the situation of only the sole supplier of the system and the sole supplier of the plate when adopting the thermal technology, but also the version of Fujifilm. The material is approximately 20% more sensitive than Kodak Poly-Light's plate, which can significantly increase production efficiency.

CTcP In addition to BAsysPrint's CTcP, Alfaquest also demonstrated its FasTrak CTP/C system in Europe for the first time. Fujifilm provided CTcP with a special UV version of the media, and collaborated with basysPrint, Manroland, SandyScreen and PPI Media in Europe to look forward to the launch of new media.

Agfa ranks first in newspaper CTP market

At Ifra 2003, Agfa launched the Advantage entry-level CTP system, Polaris X series new model, N91v photopolymerization version, Affirma closed-loop system, and the new Arkitex newspaper printing workflow.
New low-end CTP system Agfa launched two new low-end CTP newspapers, one is the entry-level Advantage DL 3850, which uses a dedicated violet laser diode, providing 1800dpi resolution; violet laser imaging head can be used Sublima hybrid Screening technology increases the resolution to 2450 dpi for commercial printing. At 1016dpi resolution, the system can produce 100 plates per hour. According to Agfa, the future Advantage models will be upgraded to produce an additional 30 or 60 plates per hour.

The other is Polaris X Series XE (FD-YAG) and XEV (violet laser) entry-level low-end systems. XE and XEV replace the Polaris 100E, producing 120 plates per hour, which can be imaged on full-size plates; the version car can carry 800 or 400 full-size plates. Polaris XE and XEV have a resolution of 1800dpi and can be screened with Sublima. After the two models have been upgraded, the number of plates output per hour will increase by 30, 60 or 80 sheets.

The violet laser plate N91v N91v is the violet laser version of the Agfa N91 photopolymerization version. The violet laser N91v version has the same printing characteristics as the N91 and can be flushed with the same chemical PD N91 in the same plate processor. With N91v, the increase in intermediate tone points can also be reduced from the previous 12% to 14% to 5% to 6%. It is reported that the violet laser N91v will be produced in the United States or China according to market demand.

Workflow Arkitex Arkitex has more than 50 technological innovations and improvements, including many new features related to prepress and printing; Arkitex uses PDFs in its entirety; PDF pages are used for imposition, page transfer, and soft proofing until the end Output. The newspaper system has been accustomed to using the bitmap format. Now it can be completely replaced by PDF. This is also a trend.

Agfa's acquisition of Esko As we all know, Esko-Graphics has always wanted to separate its newspaper section. Now, Agfa has taken over this part of Esko-Graphics. In this way, Esko-Graphics DMX CTP will stop production, which means the internal drum CTP completely disappeared in the newspaper market.

As a result of this merger, Esko-Graphics' original 160 DMX CTP systems and approximately 120 users using Eskonet workflows will be serviced by Agfa. The Esko-Graphics newspaper workflow Eskonet 2.1 will be developed and brought to market under the guidance of Agfa. Agfa will carefully study Eskonet to see if its modules can be applied to the Arkitex workflow.

Ranked first in the world's CTP market During the year from Ifra 2002 to Ifra 2003, Agfa has installed 160 sets of newspaper CTP systems worldwide, of which 70% are silver laser systems using silver salts. At this point, Agfa's CTP installed capacity in the newspaper industry worldwide has reached 850 units, ranking the leading position. If the newspaper CTP business of Esko-Graphics is included, Agfa’s share in the newspaper CTP market is more than 60%. With the launch of N91v photopolymerization, Agfa expects that 80% to 90% of CTPs to be sold in the future will be violet CTPs.

Industry insiders believe that in today’s newspaper CTP market, Agfa has a 2/3 market share and is the leader; other competitors can only fight on the remaining sites. People will pay special attention to the second-ranked Krause, while still observing the trends of other manufacturers.
