Cost of Emulsion Printing/ 2022

Posted on Posted in art biz, da net, film, overnight notes

Dated, just because, not because I will update this post. This was an impulse topic that has expanded to because of a recent youtube viewing.

Simple facts: assume you shoot 4×5 B&W film, and make 16×20 prints. What is one pass thru the process cost, excluding chemicals. Yep, a big exclusion. You can add your own chemical costs, right?

I used big search, two online stores were used; I just wrote the lowest and highest prices:

  • Film (4×5): 25 sheet at $1.60 per sheet. 100 sheet at $2.00 per sheet.
  • Paper RC (16×20): 10 sheet RC at $4.90 per sheet. 50 sheet RC at $5.60 per sheet
  • Paper FB (16×20): 10 sheet FB at $6.00 per sheet. 50 sheet FB at $7.00 per sheet

What surprised me was the quantity pricing; it isn’t cheaper buying more. That is because we see different brands offering different sizes. High quantity brands are also the more expensive brands.

Youtube. A source for much information. One person has matured greatly in their presentation – not so much in caliber or skill, but in information quality. They are polished, and have been for years. That’s why they have large following. Look and voice.

The following video seems remarkably useful. It is about film from a moderate technical vantage point. It should be, she is a spouse of Mirko (of Fotoimpex/Adox.)

Newton Rings

Posted on Posted in da net, labnotes, the Lab

Newton rings are those colored irregular circles you may see when two smooth surfaces are in contact. Film touching glass is the situation most lab workers ask about. The common advice is to use anti-newton ring glass in the negative carrier. Alternate methods: control humidity (to around 40%) — use a spray such as odorless hairspray, use oil carrier, use talc powder.

So, disrupt the surface by making one of them less smooth. That’s the general idea; workable if you are using only one piece of film, however, in a mask stack you will have more than a single piece of film. These two sheets of film may have newton rings if placed back to back, or if one has a smooth emulsion layer. 40 years ago in labs we didn’t see this with Sep Neg type 1 (or 2) and Pan Masking film because Kodak had solved it with design of the emulsion. Now only Kodak Professional Tri-X 320 has the surface tooth; there for retouching — this film isn’t the best solution for masks or separations, alas.

Some possible products, or items to use to cut down on Newton rings. AN glass is available widely. It isn’t rare although reading the forums it seems to be lost and gone.

Some chemicals used in those anti-newton cans of the past: cerium oxide; STAYBELLITE ESTER.

Offset press powder consists of vegetable starch.

Or, try SX 2001 Scannex Anti-Newton spray from: http://www.aztek.com/Products/Aztek%20Imaging%20-%20Scanning%20Supplies(main).htm

There is a patent on using spray to control newton rings which offers some advice along with a description of the problem. https://patents.google.com/patent/US4575398A/en
