|First version of the Raster Printers Daytona T600uv experiments with LED curing|
The Raster Printers Daytona T600uv was one of many new UV printers by various manufacturers shown at ISA trade show, 2007. The Daytona T600 prototype used Spectra M class heads, which are MEMS technology printheads.
The original version used one set of LED UV lamps. Other than the Inca Spyder 150 and the Luscher JetPrint , this was one of the few UV-curable flatbed printers in the world to use LED lights at this date. So far, in that year (2007), not many other companies have been successful.
But then we spoke with another company that had both LED lights and a special UV-curable ink whose chemistry was tuned specifically for these LED lights. FLAAR inspected their headquarters in Novosibirsk, Russia. There was a two-day program on UV printers here with lectures by FLAAR both days. By late 2007 this company had a second-generation printer NEO UV-LED Evolution . Their current LED version was exhibited at DRUPA 2008.
But after several months of trials, Raster Printers decided to drop the experiment of using an LED light, and returned to using two conventional mercury arc UV lamps. Mercury arc UV curing lamps facilitates a better cure and faster printing speed. This leaves the Inca Spyder 15, the Russian Sun Neo LED UV as the only two printers using LED lamps in 2007 that actually can accomplish curing. The Luscher JetPrint has not been successful, but for other reasons than using LED curing lamps (despite being Swiss technology and a printer that costs over half a million dollars). The Mimaki UJC-60uv hybrid was exhibited at DRUPA 2008 and Shanghai 2008 with LED lamps, but they were not yet curing the ink (the ink was still tacky to the touch).
Although LED lamps for UV printers offer less heat and thus are beneficial for printing on thin materials, it will take more advances in UV-curing ink chemistry before LED lights are used more often. But by the time of SGIA '08 and ISA ‘09 you can expect several more UV printers using LED lamps. So clearly this is a UV lamp technology to learn about. Indeed at DRUPA 2008, Mimaki, KonicaMinolta, and Sun LLC were all displaying wide-format UV hybrid printers with LED curing lamps.
Now we are going into 2011, and so far I am not convinced that LED curing is fully adequate. So for me it is a positive fact that EFI Rastek T660 does not use LED curing. However I recognize that LED curing is becoming more common, but the fact that Mimaki had to add a second lamp system to their LED-curing flatbed is all the more proof that the FLAAR Reports evaluation of LED curing has been correct. Since FLAAR does not sell printers we can be a resource to help provide the truth about pros and cons of printers.
EFI Rastek T660 (updated Daytona T600UV) flatbed printer
If you compare other entry-level printers, you will find the others lack white ink and lack variable-droplet precision printheads. The T 660 UV has white ink and can print 4 pt type easily. The quality of the output of this printer beats most other entry-level printers (and even is better that some flatbed printers with Toshiba Tec printheads and costing $140,000).
At SGIA ’08 and ISA ‘09 the Raster Printers was again in the EFI booth under the new brand name EFI Rastek (as it was at DRUPA 2008).
EFI Rastek T660 is the new name for the Raster Graphics Daytona T600
EFI bought Raster Printers during 2008 and so some of the brand and model names have changed. EFI Rastek T660 is new designation for what started as the Raster Printers Daytona T600uv dedicated flatbed wide format inkjet printer.
But all the printhead models are being changed, since MEMS printheads do not hold up
Through not fault of Rastek, Inktec, L&P or any other printer manufacturer who started with the impressive Spectra M-Class printheads, all these printers now have switched to a new head. This switch required about 4 to 6 months of additional work on new electronics, ink feeding system, etc. This is why the Rastek T660 was in late 2009.
If you need a flatbed printer larger than the EFI Rastek T660 you can now opt for the T1000
The EFI Rastek T1000 dedicated flatbed printer is now available, in case you need a larger format than the T600.
