Making Prints Cooler

[pentaxuser]

A thought: a trade secret has no real value if there is no commercial advantage to be taken from it, assuming of course that surrendering that secret does not compromise other parts of a company's offering.

If Harman are completely sure that they will never re-introduce this developer, perhaps there is a persuasive case to be made for them releasing the formula into the public domain?

I may be wrong but I think that this has been asked of Ilford in the past and Simon's reply was that part of the formula is either a commercial secret or has an ingredient that would not be available to DIYers

Others may be able to confirm or deny my recall

Yes it was discussed before. Lots of us said we'd buy it. I think I said two bottles - I don't get to print nearly as much as I'd like. They looked at it but the market wasn't enough.

But isn't the question now whether the introduction of the new FB cool tone papers may have changed that market?

Good point!

Ra ra, go CT Developer!

Oh Simon, paging Simon...

I really hope Simon and Ilford will reconsider relaunching cool tone developer.

At least in special order batches ??

There are many other cold tone developers. Just mix your own. Elon is Kodak's tradename for Metol.

Michael R is spot on, a component in CT Dev was made 'in house' in our Kilo lab ( where we make specialist / hard to find / no longer made / or prohibitively expensive or available commercially in unsustainable volumes for our business.

As you know I did request the product to be re-introduced but this was clearly rejected by the board due to the minimum manufactured volumes versus the write off sustained on the original manufacture.

Very sorry.

Butbut...you didn't have CT FB paper then. It would be a great companion product!

Gerald - those MQ-ish cold tone developers you list will still end up a tad warmish with Cooltone. They'd work with Polygrade V, but not in this
case. I'm not implying the results will be unacceptable, but definitely not as cold as this paper gets. Maybe some PQ tweak would do better;
but amidol is the actual silver bullet.

Printing with the new cold tone fibre base paper for the first time last week, the image didn't seem particularly cold with D-72. My experience is that the BTZS additions don't seem to work with modern papers.

Amidol is expensive and stains anything it comes near. Any other recommendations?
