TechNova is one of the world’s largest manufacturers of digital & analog offset printing plates; printing chemicals; and inkjet, laser and drafting media. It is primarily based in India but their products are available in many countries through their authorized dealers.
In Drupa 2008, Technova launched their Metal CTP System, Metijet and Metijet Plus. Metijet is imaged on an inkjet printer such as Epson 7880 at maximun 120 lpi and then it is baked for a few minutes before being mounted on the press. Metijet Plus, on the other hand, is imaged on the Epson Printer and then it is exposed on an exposing machine before being processed and mounted on the press. It is capable of holding 150 lines per inch.
Currently, Technova’s Polyjet system consists of Polyester CTP and Film to Plate system. The Polyester CTP plates are known as Polyjet Plates which are imaged on the Epson Printer and then baked for a few minutes and thereafter transfered to the press for printing. They hold good registration and fine halftone reproduction. The only difficulty is that the right temperature for baking is hard to get in the beginning. A linearization file has to be applied to get correct output from the inkjet printer.
Technova’s film to plate system includes the InstaDry film. The film holds excellent registration and gives good four color printing plates for the press. They come around 90% close to imagesetters. This film is also imaged on an Epson Printer.
The Epson Printers offered by Technova along with the system are available in 17″ and above widths. The software used is Technova’s Polyrip which is really the Open Rip software.
Technova’s Polyjet System comes under Rs. 600,000 for the 24 inches width Epson printer. The price may have increased now as this is the price that I received one or two years back.

For this polijet printer we are using the same ink used in inkjet printing or the speciality is in plate.
The ink is the same but the film and the plates are special.
Will we be able to use the epson printer supplied by technova for other applications apart from this polymaster application? if so will the printed need to reghost/reboot? Just wondering!!
You can use the printer for printing of photographic images and for high quality proof reading. There is no need for rebooting. You only need to change the paper type in the machine if you change from roll to sheet or vice versa.
Which is the best offset plate system can be prepared easily , economically, useful for both sheetfed and offset in a large format without compromising the quality of print in large quantity of 10-15000 impressions?
can this be used for 4 colour printing?
heard there are registration problems and thus only good for single colour.
There are registration problems with the polyjet plates as they are heated after imaging. But you can use the metijet plates for good quality color printing and there are no registration problems as such.
