I have seen this referenced several times over the last year and while Ware
did put this out in his scientific paper, it is not a required step within
the Ware/Malde process. I have had several conversation with Mike Ware on
that topic. There are several members of this list that have, i believe,
taken workshops from Mike, and I would think that they could also support
that the Ware/Malde process does not REQUIRE the dry and rehumidify. It
does show how the humidity will affect color and speed of the print. Ware
also provides, through that paper, specific color that can be achieved by
I think that we can all agree that the eye can judge whether a print has a
desired look. If one can get that color by simply drying a coating with
cool air and quickly printing, or by drying and rehumidify, each method can
work well. I see an advantage in slowly adding humidity, 30 minutes or so.
In that, one should be able to achieve a more even humidity level throughout
the paper. I have seen this as one fall back in Zia type print from reports
on this list.
