I have tested Pictorico OHP film, Epson 2100 combination with silver
gelatine paper and found that a key factor is the colour of the negative -
choose the wrong colour and the results can be very grainy. Green negatives
give the best results for me. You might want to try Mark Nelson's Precision
Digital Negatives system, a key component of this system is choosing the
best colour for your negative.
