Which factory made these new 52x Dysan CDRs ?

My best guess will be ritek, as most dysan discs I’ve used have been produced by ritek. But I can’t say for sure.
Hello to all 
I’ve bought these 52x CDRs yesterday. I have Lite-On CDRW and SmartBurn Checker can’t recognize them (CDR Atip Reader too). 32x and 48x Dysan discs have been produced by Prodisc.
Definitely Ritek.
