[alt-photo] Re: One-coat temperaprint

[alex.j.chater]

hello Rafael

The problem of the amount of pigment in the mixture is that as you  
load more and more in, the the coating will become heavier and have  
more contrast. Beyond 5 parts of egg mix to 1 part of pigment, the  
number of tones reduces and the detail becomes more crude.

Are you using the Temperaprint on a clear base (effectively using the  
light stopping properties of the Temperaprint coating), to create a  
further image on another base with the temperaprint, or are you using  
an existing image on a clear base to print an image with the  
temperaprint

If you are just laying a coat that you are going to draw into then  
the amount of pigment to the egg mix is not really an issue until  
there is not enough egg to bind the pigment together. Up to that  
point I would suggest more exposure
