Punching Holes

Posted on Posted in coursenotes, dye transfer, Getting Stuff

machines change as their maker learns. Registration holes in film came after registration of masks and mats. At first film was on glass, then on thick flexible plastic (celluloid). Until DuPont invented strong thing film-base, first used in lithography, lab films couldn’t withstand much punch, pull, position, alignment. Besides, the emulsion has always ‘shifted’ size more than the film base. Most professionals watched their relative-humidity and drying angles of critical film.

The following two punches are from the most known lab equipment maker. Most known among those talking today. Note how the change in punch systems. The first, very simple — a bar acts as leaver. Over time the leavering matured — becoming smoother. The positioning guides didn’t change. Not even in size of hold-down. And the badging became a glued on plate with serial number.

1963. Condit Register Strips for Kodak and Condit punch systems.

Business Registered Date Jan 05, 1962

These were standard items in student kits at schools.

Warren L. Condit, 83, husband of Elizabeth (Myott) Condit of New Lebbon Road, Newtown, died March 2002 in Mediplex in Southbury. Warren was born in Staten Island, N.Y., July 1919. He was a US Navy veteran of World War II, serving from 1940 to 1945 as a radioman, first class, and photographer.
From 1947 to 2000, Warren operated Condit Manufacturing in Sandy Hook, a company specializing in equipment used in the development of color films, the manufacturing of the teleprompter, and violin making tools.

In its first decade, imbibition printing at Eastman Kodak changed, in means and manners, not only in name.

At first, it was the Eastman Wash-Off Relief process. When it became Kodak Dye Transfer, brochures were updated several times.

Note the cover photos showing the transfer operation: the early one shows the Blanket method; the later, color, one shows the transfer table with Kodak Pins.

Even earlier the “slip sheet” was used. This was the way with Eastman Wash-Off Relief (WOR).

information passes, even through unsigned handouts. My Cooking Color set of notes on setting up dye transfer/wash-off processing for the small, independent worker.

… but then, I gathered them from Henry Smith and several dozen forgotten cohorts… it is only when publishing that we need the name on the spine.

NB: I have written a pamphlet specifying the steps to making an adaptable punch+pin system using mostly off the shelf items. members of OIC maintain it, as well as having several sets ready for new members.

Jigs made film testing easier. Commercial ones meant that those without skills or machine shops could have easy systematic emulsion testing in their lab. The Cine-pro company also had some of the best stainless trays ever made. None of it was cheap … prices were on the order of a few days pay for the average lab worker.

what motivates
the maker isnt always known… usually it is reaction … either to a known, but as likely to an unknown, even a rejection.

 two ways of minimizing dye bleeding. We always dried our 
prints on a drum dryer. The other was not to condition paper for more 
then thirty minutes. Any left over paper was used for test prints. — dye transfer

Other notions collected this week

Early reference made to Three-color methods and processes with special detail about Jos-Pe and Pinatype.

I’ve been going through notes on matrix making along with tanning methods: why developer replaced bleach.

finding the person behind the process leads to much more information about the process. These two people were the keys to Kodak’s emulsion coating discoveries. Nadeau and Starck are on many patents that would be key to making matrix film or Flexichrome emulsions.

While digging into the past there is the challenge of staying focused, limiting attention, and missing serendipitous materials such as:
