Is the cosmos holo sheet different between Japanese and European languages for early sets?

I think this applies to Base, Jungle, and Fossil - Japanese is comsos, English is the galaxy/stars, European languages are also cosmos. Are those 2 cosmos examples the same or different sheet style?

I’m 99% positive the cosmo holo foil effect used on Japanese cards and Rocket-on Western cards are the exact same foil stock. MAYBE there are some minor differences due to different manufacturers producing it between Japanese and Western cards, but they’re effectively the same foil.

I think the holo patterning is identical (you can compare landmarks in the pattern to check). Not sure if the sheet is fully identical. Even if the sheet is fully identical, the way the printers/manufacturers decided to join the holo sheets could also be different, leading to possible double swirls in European cosmos cards but the same old line-through-the-large-orb shim/weld line in the Japanese cosmos cards. The shininess of the holo could also change with how thick the white layer is, even with identical sheets.

Another thing to consider is that I think we have roughly an okay idea of how Western sheets may be printed, but I’ve seen uncut Japanese sheets (think @qwachansey has one) that have completely different sizes (think it was like 4x4 instead of 11x11 or 11x10), which suggests the physical sheet might be different too.

Thanks for the details. Seems to be the same base material, which is what I am after.

Trying to determine if, for example, German Jungle cosmos is different from Japanese cosmos.

Old back Japanese sheets were 8x8 with separations between the quadrants that WOTC sheets did not have. AFAIK the holo print layer (the sheet background) is the same for WOTC Base 2 / Rocket onwards & old back Base onwards

So safe to assume old back Japanese and early German, French, Italian, etc are the same as well

Yes

I swear you asked this over a year ago?

Right, in the Eevee thread and there wasn’t really a conclusion there. Or if there was, it should have been more out there
