print flattening update
February 23, 2006, from Lloyd Erlick,
My darkroom is pretty much functional again after a hiatus. Yesterday I put my print flattener back into service. It's the high-tech version -- a stack of heavy flat things with a weight on top. Some of my heavy flat things are sheets of glass and some are melamine-covered particle boards of appropriate dimensions (plastic covered both sides). Before using my Print Flattener DeLuxe, I had to clean all the heavy flat things, both sides. The melamine is white, so dirt would show. They were surprisingly clean, actually, even though I've been a bit careless with them recently. I used some ammonia and distilled water on clean rags to swab them. This post is about the tiny things we do that can contaminate our process. While cleaning my plastic covered boards, I found some (mercifully few) tiny black spots. I thought they would be permanent, but I noticed the ammonia dissolved them extremely slowly, and applying a thumbnail broke them up if they were wet with ammonia. Well, it didn't take long to figure out the source of the specks. I sign my prints with India ink. Obviously I have not been patient enough to let the ink dry every time I use it. I'm just glad there were not more black specks. It should be no problem to flatten prints with boards that have dried India ink on them. Once dry the stuff certainly will not transfer. But the presence of the specks gives the flattening devices a dirty look, and makes examining them for real dirt take much longer. It also means I have been careless in handling my prints in the past! I'm just lucky no smudged prints resulted. (Hm - none I noticed, at least ...). So, an unnecessary update. Take more care (even more care ...) with print finishing. Do not allow dirt to accumulate on print flattening devices. India ink on the glass flat things scraped off in an instant. (On glass I could use a razor scraper, but not on the melamine.) India ink on melamine is tenacious and tedious. In the past I've always done print spotting and signing before flattening. I'm not sure why, since flat prints would be easier to spot. Maybe I didn't want to bother flattening prints I decided not to spot and sign. But no signed prints under the flattener would mean no ink transfer ... regards, --le ________________________________ Lloyd Erlick Portraits, Toronto. voice: 416-686-0326 email: net: www.heylloyd.com ________________________________ -- |

print flattening update
Good advice here. Thanks. I always keep clean white mat between my prints
and weights or dry mount press. A hint of dirt and they are replaced. "Lloyd Erlick" Lloyd at @the-wire. dot com wrote in message ...

I think I'll go get some clean mat board. regards, --le ________________________________ Lloyd Erlick Portraits, Toronto. voice: 416-686-0326 email: net: www.heylloyd.com ________________________________ -- |

I use a dry mounting press for flattening. Flattening is part of the prep for dry mounting but one can simply flatten the prints. the prints are put into the press with a sheet of release tissue on the emulsion side and a couple of sheets of thick "construction" or kraft paper on either side. The paper is dryed out in the press before using it. I close the press on the sandwich and leave it for about 2 minutes, it isn't necessary to lock the press. Then I put the whole sandwich under a flat weight. While a thick sheet of Aluminum is best even flat plywood will do. Even though there is some padding from the paper the weight still has to be free of particals because they will emboss the print surface. The print needs only a couple of minutes under the weight, just long enough to cool. The idea of the release tissue is to prevent drying of the emulsion. The paper drys out from the support side which tends to equalize the shrinkage of support and emulsion. I've found that prints flattened this way stay flat even with fairly wide variations in relative humidity. -- --- Richard Knoppow Los Angeles, CA, USA |

print flattening update
I bought mine new for cost in 1996 (1972 cost!) the store that had it was
happy to unload it since everyone had moved away from using FB papers and no longer needed presses to mount their RC prints and were instead using peel and stick mounts (cheaper in the short run and I use them myself for Ciba/Ilfochromes, since the emulsion is relatively fragile). So one day I just shot him a price, since his sticker code was an open secret I knew what he had paid for it, and walked out of there with a new Technal press. I still drymount some prints but use it mostly for print flattening chores. It's not a luxury when those big jobs come around! -- darkroommike "Lloyd Erlick" Lloyd at @the-wire. dot com wrote in message ...

The catalog from the Elliott Erwitt show at the MOMA last summer works
well as a weight. it will flatten most anything. |

Your prints then are dry prior to flattening? Nothing separates your prints either side from the weighty sheets? Dan |
