Hello Ron,
I have posted this question on Jim Browning's Die Tranfer Yahoo Group. I figure that you are old enough to remember Dye Tranfer. I am thinking about evaluating my current pan emulsion as a pan matrix film. When processed and fully dryed the emulsion shows a feelable positive relief. I Am interested in the dye transfer process. I am wondering if you know what thickness to lay down for a panchro matrix film. I understand that, for ortho matrix film 10-15 microns is required, but a panchro matrix film should be "condiderably thicker"
