Imbibition Notes: Matrix Punch

// Kodak directions were complete. More information was made available in the product datasheet than in the instructional guides. Labs always had access to support from the marketing group. If you were big enough, or persistent, you could talk to the research group well into the 70s; then it changed. The product was on the way out — no one wanted to say. Now, I know that the reason my contacts from the 60s called from home was that the labs weren’t supposed to be talking.

A main Kodak invention for imbibition printing was their film punch. Looks like a very complex paper punch. Not far from wrong, although paper punches aren’t always best for thick sheets of plastic like film.

Pan Matrix sheets came pre-punched to fit the Kodak Transfer table.

An early fight with Kodak was over large rolls of Pan Matrix film. They wouldn’t make it… even though we had many accounts wanting large displays from original color negatives. So, we had to devise the interpositive method — then we had talked to DuPont. And Ansco.

It is the Kodak Blanket, the method used from the first decade of Dye Transfer. The early guides (E-80s) showed its use. This was the time of cut-n-but registration — the form inherited from litho-press plate work. The Condax patent references earlier litho patents.

Kodak’s system for making Dye Transfer prints included large pin system. The film used couldn’t take fine punches; not if you were going to put film off and on many times, such as what happens when making real prints. Theoretical prints could be made by punching glass plates, sadly, real glass plates would snap if you punched them.

A punch for the film + an easel used during exposure + pinned transfer board + a roller for rollup of the mats onto the blank.

This was a standard set of equipment found in commercial and weekend labs. These items went out of production by 1980. From the mid 60s they were specialty items sold through graphic supply houses, not regular camera stores.

In 1968, Adolph Gasser (big San Francisco store) didn’t know about them, nor dye transfer supplies. I worked with them to make my order; standing with them to make the call back to Rochester. A long time ago. It foreshadowed much of what would come to the very small community of dye transfer printers.

Open Registration

Much of darkroom work is hand waving. Aligning images to build a print is part of the world of assembly processes.

Projecting a beam of light through a modulator, such as a piece of film, is the way of the darkroom. The enlarger is light and lens. We increase our control by being able to change the color and intensity of the light. These are the little pieces we build a world with.

Here, we see a color print, made from separate BW negatives, using filters, manual registration, and RA-4 color paper.

Notice how casual the assembly is. No film punch; no micro calipered, glass carriers; none of the carping crap posted on the Film Forum by slow moving Flim Flammers.

Many Divided

Next, Jerry Uelsman shows his method of making combination prints. He uses several enlargers, each with a negative of one element of the finished image.

Uelsmann in darkroom

There are people who use the computer to write their essays and there are people who still use a yellow pad and a pencil. They both can write excellent essays, stories or whatever. The process is the means by which you complete the image, but you don’t want it to be the end. There was a point at which the emphasis was on the Zone System that was all so technical. So you had this precise full tonal scale image, but what was the subject matter? It’s a cat or a sunset. So what? I’m committed to the darkroom, but I believe that if I had been 20 years younger when Photoshop came out with its visual options, I might be sitting in front of a computer rather than standing in front of an enlarger.
