I don't know which book you are using for formulas but regular Final
transfer papers made of *hardened* gelatin coatings should be avoided for
double transfer carbon (i.e., from plexi). Normal formulas call for a
relatively thick layer of *slightly* hardened gelatin, e.g., 10% gel with
potassium alum (not chrome alum) and certainly not glyoxial or formalin.
Thank you for the clarification. I appreciate the information.
