ADOX Film.... Manufacturing, Shipping?

[mshchem]

THE GOODSTUFF IS HERE! FIRST TIME WITH ALL OF THIS. LOOKING FORWARD TO TRYING THE XT-3, I'VE BEEN USING XTOL FOREVER. FREESTYLE DELIVERED THIS TO ME YESTERDAY!
QUALITY IS ECONOMY!

The cat (Virgil Ivan "GUS" GRISSOM) likes it too!

I was not aware that other quality manufacturers had abandoned the interleaving paper.

Good to learn that even you do not know everything, even not about your competitors...

But as you were surprised there is not, others as seen were surprised there is. Which shows that there is no common knowledge. Which again might result in thinking over communication with the customer as I hinted at above.

Mirko, I have absolutely no insight as to where your products are used, but suspect very little sheet CHS-100 II is sent anywhere near the equator.

Do you know whether your sheet film hardening is comparable to the modern hardeners other manufacturers like Bergger, HARMAN and Kodak use? If so, I can report that here in coastal southern California, where relative humidities of 70% to 90% are typical, I've never had sheet film from any of those companies stick together, even after Kodak's laminated, sealed inner envelopes are opened for a while.

Eliminating your interleaving paper might have another benefit. There are small clear areas on my CHS-100 II sheet film negatives. I don't have a microscope, but, using a 30X loupe, those spots look like they might be particles from the interleaving paper blocking light during exposure. Going forward I'll bring a large Static Whisk brush into the darkroom and gently run it over the emulsion side of sheets before inserting them into holders. The edges of your sheet CHS-100 II are rather rough and upon close inspection reveal an uneven emulsion edge. However, I don't think emulsion flakes are the problem since, if they were, negatives' spots would likely be of slightly higher density than the clear film base I see.

Thanks very much for looking into this.

CHS II is using identical hardeners like Harman. Can´t comment on Kodak but the scratch resistance of all quality films is more or less the same. The interleaving paper has never had any issues in over 20 years of manufacture. It is clean and has no particles, just outrageously expensive .
After cutting the stack the sheets are inserted into the packaging. There was also never a problem with cutting dust on the edges in sheet film manufacture. We will look into this

This is interesting to learn all this. I am glad that I asked. I have lived in the tropics and it certainly does add a whole different set of problems than other locations/climates. While I am no scientist, I can provide anecdotal evidence from my experience with other 4x5 sheet films. Here in the southern part of the west coast (USA) I have never had a problem with scratching film. I consider Rollei RPX 25 the softest emulsion on the thinnest base. I believe that very high resolution films need as thin of a base as possible. As far as soft emulsions go, Foma seems to be the softest. On the other end of the scale, Kodak Tmax 100 seems to be coated onto a sheet of plywood. I have literally dropped a sheet or two on the floor, hunted around for it in the dark, picked it up with bare hands, brushed it off, loaded it, and not had scratches or dust. I can’t imagine that too many other film stocks could survive this ordeal and remained unscathed.
As far as the paper goes, my two cents worth of opinion says that I could do without it in my current climate and not notice much difference. I do reuse the paper though, it’s useful.
Thanks for the dialogue, it gives a much deeper understanding of just how complicated, intricate, and frustrating being a film manufacturer must be. I do appreciate Adox and LOVE your products. I hope others will give them a try and support Adox. No other film manufacturers that I know of come on here and interact with those of us who actually use their products. That alone speaks volumes about Adox.

...I believe that very high resolution films need as thin of a base as possible...

To the best of my knowledge, base thickness is unrelated to resolution. You may have heard something about "thin emulsion films" and are confusing emulsion with base.

 

[AgX]

Eaxactly.
The idea behind ultra-thin base was to save volume and mass of films. Typically with surveying/reconnaissance photography from airplanes and satellites. But also emplyoed at microfilming.

Or you have some resellers, who seem to use non sheet film and have it cut into sheets. Years ago I bought a box of Rollei ATO film to play with in the dark room, to make slides from negatives. I only briefly made a few experiments and still have the box. It may actually be a very nice ortho film, maybe even a lith film. The base, if I remember correctly is quite thin. I assumed it was a film, 135, 120, or aerial, simply cut into 4x5. I mean, great to have it, and eventually I'll do someting with it, but a reminder why 4x5 is using a more sturdy base material.

But if the only way to get Velvia 50 sheets back is to buy a 135 master roll and have Mirko cut it into 4x5, so be it. Sadly I didn't win the jackpot...

I want everyone to make a predictable, decent profit. Some products will come and go. Adox ability to convert master rolls of paper is a terrific asset. Heck I can dream of 3 1/2 × 5 1/2 postcard paper, RC and DW.

 

[Lachlan Young]

@lantau Most likely the ATO is repurposed litho material which tends to be on a thin (0.1mm or so) polyester base. Some aerial films were coated on even thinner polyester bases.

 

[AgX]

Neither litho nor aerial.

 

[Lachlan Young]

Neither litho nor aerial.

In that case, a document/ duplicating emulsion. Probably an Agfa Copex derivative.

 

[AgX]

Neither

 

[Lachlan Young]

FIlmotec/ Inoviscoat emulsion for a print stock is the other realistic option (depending on who Orwo/ Filmotec's coating partner actually was at the time).

 

[AgX]

Sorry Lachlan and Lantau, I was just busy with another thread. As result I thought you both had it about the Rollei ATP. (Being able to read letters would be benefitial.)
Concerning the ATO, it sure was no Copex as those had a different spectral sensitisation.

From what I could find, ATO seems quite likely that it could have been a special coating of Filmotec's PF2 emulsion on sheet film base by whichever coating partner they used at the time - and the current Bergger Print Film may be the same thing, but the v3 emulsion and made/ coated at Inoviscoat.

Good afternoon
Can you please tell me when the film Adox CHS 100 II ISO 100 4x5 will be available in the store in Berlin?
With all respect, Andrew!

 

[urnem57]

Freestyle seems to be out of Adox CHS II in 4x5.
Any idea when they will have it again?
Thanks.

I only saw this now. You can check in our webshop if something is available in the store. If it is not and there is also no date given when we expect it back- then we do not know this. With our own products reasons for this can be delays in the supply chain or an unfortunate holliday/sick leave combination in a departement.
