Could someone explain this (T-Max 100 in D-76)

Just out of curiosity, I was checking out Kodak's pdf on D-76: http://www.kodak.com/global/en/professional/support/techPubs/j78/j78.pdf

On the third page there is a chart of development times, and part of it confuzzles me. What is the difference between "T-MAX 100 Professional" and "PROFESSIONAL T-MAX 100," aside from word order and capitalization? Is the second one more professional, since it's all in caps? It wouldn't be a big deal, except it gives completely different development times for the two of them. Maybe I'm just missing something about the chart, but does anyone know what the heck is going on?

T-Max 100 Professional was the earlier version, and Professional T-Max 100 is the later version, if I'm not mistaken. Among other things, the later version added a UV absorbent layer, which makes it less useful for alternative process printing.

Thank you! Is there any way to tell which one mine is? Or is it more than likely it's the new version?

hi luke

the notch code for the old tmx went like this -----------v-v--
the notch code for the new tmx goes like this ------v-v-v-v--

not sure how you would figure it out if it wasn't sheet film,
maybe contact kodak and find out from the info on box / roll ..

i haven't bought tmx or tmy since the emulsion change so it's easy for me

good luck!

If you have purchased recently it is sure to be the new stuff, which really isn't that new any longer, except compared to what's in John's fridge. The edge printing is different, the old stuff says TMX 100, the new 100TMX. The new stuff also has a bluish sheen when still wet off the reel probably due to that UV stuff David mentioned.

—NOTICE—
To reflect our enduring commitment to black-and-white
photography, Kodak moved black-and-white film production to an
even more advanced film-coating facility in early 2002. New
technology applied to these superior, time-tested emulsions
resulted in slightly different processing times for the film family.
But the same great films—those you've known and trusted for
years—will still deliver the same breathtaking results.
The packaging examples below are the best way to determine
which film you have. Refer to the corresponding publication for
development times.
Note: T-MAX 400 Film was improved in October 2007. Some film
characteristics, including processing times, have changed. Refer to
Kodak publication F-4043 for packaging examples.
2002-9/2007 packaging, refer
to this publication (F-4016)
New (10/07) packaging, refer
to Kodak publication F-4043:

Dear Luke,

The packages are different and you will find the differences noted in the data sheet.

Thanks very much, the data sheet certainly cleared it up for me!
