Re RC papers I just spent the morning running paper tests using LPD I just mixed . The tests were to see if the different dilutions and times affected paper contrast and tone on Ilford MG IV RC, they didnt The result pretty much confirmed that the batch of paper I have is developer incorporated .using the simple method of AAs factorial timing. A print in LPD 1:3 70 degrees should not immerge in full density in 15 seconds! Not when the same type fiber paper is taking 30 seconds to just begin to immerge .The paper I got about 2 years ago, which I kept frozen, was the 40 sheet packages I see still advertised on Amazon. As there seems to be no expiration dates printed on paper any longer it is buyer beware! Now I question the Arista Ultra and EUD papers being sold by Freestyle. I have used them and they are fine for proofing etc. but seem to react like a developer incorporated paper too Incidentally some kind soul sent me an answer as a private message, which I appreciate. However in sending the reply I messed up and lost the message. But thank you. That also is why I will never go digital Computers have mind of their own. Life is tough enough.
