First some info about other manufacturers.
Vivastar - Was a Swiss companny which went bankrupt in arround I think late 2001/early 2002
The tried to spin off two daughter compannies. One was a trading companny which closed later in the end of 2002.
The other was the R&D devision which was bought up australian companny and was named to Interaxia.Which was a technology supplier for quite some compannies (3A/SKY/and some hongkong manufacturers) when it came to DYE and stamper technology but also supplier or manufacturing/replication sollutions.
It seems that interaxia no longer exists since 2006. The site is down, however the bulgarian devision site is still up.
Tomorrow I will do another one if I have time.
Hmm not ritek ussing Ricoh MID (supervised or not by Ricoh ?). Because Ricoh’s own production is rare !!!
