Austria 2007 Flower Definitives Offset Or Photogravure ?

Austria issued between 2007/08 a flower definitive set, total 11 values.
Question is, what was the printing method used.
Scott states that all were printed photogravure whereas Austria Netto Katalog claims that the 55, 75, 100, 125 C
were printed via offset but the 4, 10, 15, 50, 65, 115, 140 C were printed photogravure.

Joh.Enschedé Stamps B.V., Netherlands was the printer.



I'm missing the 50 C and the 65C.

Here are some close up details which appear that the borders, letters and numerals seem to indicate photogravure but
the images show a rosette type pattern which fits more with offset/litho.

Perhaps the printing was auto-typical photogravure as mentioned by Rein in these 2 previous threads.

All are in photogravure with EME cylinders - electro mechanical engraving using a Hell Helio Klischograph

Starts engraving, 2 minutes after PDF is loaded.

Thanks Rein and Rod for the info and the video
