Jerry -- I just read a few posts about Liquidol over on APUG. Sounds like great stuff. Everyone who's used it was very keen about it's image quality -- cool tones, deep blacks, clean whites; ticking all my boxes here -- as well as it's tray and stock life. I'm looking forward to trying it. Thanks for the head's up on this.

I once operated a phototypesetting machine called StarSettograph (or was it StarLettograph?) which had fonts on a long acrylic 'negative'. It used special paper, presoaked in a special developer, and the projected character appeared within a few seconds. Not only was the paper/developer combination very quick, but the developer kept for days in a dish. The developer, sold in powder form, was expensive and distribution was unreliable, so I tried various other developers. The worst problem was staining and low contrast next day.
Long dish life is not a commercial requirement nowadays. If anyone knows of a solution to the problem, contribute it here! |

Svend- I did neglect to mention that Liquidol does start to bring up an image rather quickly, so if you're using Factorial Development be ready for a surprise. I didn't use it for my step wedge tests, so I never checked the timing but I'd guess it's about 10-15 seconds with fresh developer.

Hey Jerry, thanks for the tip on that. Good to know. Sounds like this stuff is turbo-charged. If I see smoke coming from the tray when I slip a sheet in, I shouldn't be surprised.
Hughes -- is it 4812 you mean? I didn't see 482 on his site. In any case I don't think I can get that particular Moersch developer here in Canada; only his lith stuff. In the US, Freestyle carries 4812, but it's very pricey at US$47/litre...about C$63. But thanks for the recommendation; perhaps someone on your side of the Atlantic will benefit. It sounds like good stuff -- the write-up speaks of VERY long stock and working sol'n life - 8 months for the latter! Nice! Best, Svend |

Svend- Another tip: My spot check wedge tests developed for 60 seconds in 1+9 (suggested by Formulary) showed that the max density only reached 1.9, but 3-minutes reached 2.1 without toning. So when I begin making REAL prints I plan to slip in a few more wedge prints to find the minimum develop time that reaches 2.1. Just thought you should know when you begin working with Liquidol.
Incidentally, I reported my test result comparing overheated dev with fresh dev to Ron M. to update him and also told him about the 60s vs 3m results. He was happy to get that info, and he volunteered this comment: "I know that when it is going bad, increasing development times brings the image back almost to normal."

Hi Jerry,
Thanks again for another tip! Much appreciated. Sounds like this developer allows some latitude in the tray -- good density results at 1 min.; even more density at 3 min., if needed, without totally mucking things up. I get the impression you're pretty stoked to have found this developer, and with the initial results you're getting from it. As a general comment, I find it great that new products like Liquidol and the Moersch 4812 are being brought to market nowadays. And especially great that they seem to be tailored to how a lot of people work with them now...that is, like myself, multiple occasional printing sessions over a week or two, a few of hours at a time, working around a busy home life and career. Beats dumping a batch of Dektol or Bromophen after only a few prints. Regards, and wishing you a good weekend! Svend |

However, I use ID-78 in a Nova slot processor and have found the warm tone to be very subtle indeed. It obviously depends on the paper though. I'm using MGIV at the moment. |

Dilution and development
Quote:
A mentor of mine, many, many years ago said "So long as the development does not cause staining there is nothing to be lost by extending the development. You pay for the silver content, so use it". |

Stocky -- thanks for the insight. That's good to know. I might have mentioned that I'm not really a big fan of very warm tone prints, preferring to print neutral and then toning afterwards if needed. But very subtle warmth in a print is very nice indeed -- no aversion to that at all -- so ID-78 might be a good choice with the right paper. The good thing about these formulas is their flexibility -- as per Ian's suggestion on his website, mix up a batch of neutral-tone base stock, then tweak it to make ID-78 or ID-62 just before printing to suit the images. I'm not sure that's possible with Liquidol or Ethol LPD -- I will have to try adding some carbonate or bromide to each in a tray and see what happens.
At some point I intend to experiment with all four of these and then decide which works best for me. Quote:
