If T-grain Technology can be used to manufacture emulsions of astrcj nomical type, it will provide a better Detective Quantum Efficiency than any existing plate. As Dr. Millikan explains us, this increase in D.Q.E. can result in an increase in Signal to Noise ratio (i.e. increase in coil trast or decrease in granularity) or in an increase of plate speed. As Kodak and we, their customers, don’t have a lot of money to spend for three or more new emulsions, we have now to choose for a new emulsion, which might be a harder one (more contrast), a finer one (better granularity), or a faster one.
