Folks,
Michael Smith announced the Azo replacement over in the Azo forum a little while ago. His post is here (http://www.michaelandpaula.com/mp/AzoForum/one.asp?ID=9056&PgNo=&GID=9056&CID=7)

Wow! Check the dates. That announcement was made in January, and the last post to that thread was made in March.

Jay, the APUG thread I linked above is a much more recent update.

Thanks, Oren. Sounds like they're getting it dialed in. I hope the new paper is available before I run out of Azo.

Has anyone done a survey on the dMax of various papers, including Azo ?

I don't own any sensitometry equipment, but I suspect that the combination I am using today (Epson Ultrachrome K3 inks on Epson Premium Glossy paper) may have a dMax equal to or greater the Silver papers, toned in Selenium, on which I printed back in the 1970's.

Pehaps there has been a full study of this, but if so I have not seen it.

My own work with AZO gives an absolute maximum of about log 2.20, after selenium toning. Several of the contemporary silver papers will give somewhat higher Dmax, up to 2.3 or even 2.4. I don't have any idea how your Epson inkjet prints compare, but if you send me a sample I will be happy to take a reading and post the finding. I doubt very much that your Epson prints will have Dmax of 2.3 or higher, but I could be wrong.

Hi Ken.

I think Donald Miller has done that kind of comparison, and your supsicion might be correct, but there's more to the appeal of Azo than its Dmax, and much of its appeal probably doesn't correlate to digital printing in any way. For instance, Azo is very slow, so printing can be done in a much brighter environment, with far less risk of fogging, which is nice. Azo also keeps very well; I've printed on 50 year old Azo that looked better than my fresh box. Azo is very fine grained, very responsive to developer formulae, and tones extremely well. These are all very practical benefits for DR printeres that have little relevance for digital printers, and do not address the issues of Exposure Scale, paper finish, or Dmax, which are of interest to both camps, and which I leave to the more zealous members of those camps to argue, besides, my knowledge of digital printing is practically non-existent.

P.S. Those who demand accuracy can replace Azo is with Azo was where they appear above.
