Any of you guys know the use of this?
Is this piece of equipment worth anything?
This was probably for the dye transfer process, which required precise registration of separation negatives.
It could be used for any kind of masking process with large format negs or multilayer alt-process printing like 3-color gum bichromate, gum over platinum, etc.
Dry Transfer. I'd love to get get a set for trying color carbons.
That is the unit used to punch film without having pre-punched film. Matrix and Pan Matrix film came pre-punched or not, as the case may be, and both the unpunched Matrix film and the separation negatives required punching.
You need a vacuum register plate to go with it. It looks like a huge clipboard with pins for the punched holes and vacuum channels, as well as a connection for the hose. This holds the film down when you expose it.
Then you need a transfer blanket or a vacuum register board to attach the paper and then each Matrix to perform the individual transfers.
So, this is missing 2 parts from what I see, but is nevertheless valuable. I only have the vacuum register board. I rescued it from a trash bin when the dye transfer line was shut down, and was given permission to take it.
A pretty good substitute for the punch is making 3/4" x 1.5" tabs out of scrap film, punching a 1/4" hole in the ends and taping them to the edge of a negative. An office paper punch works. I do not know if you can still buy individual pins from a printers supply.
I have a Kodak 11x14" spring-back frame with the register pins and matching punch, so that was another option.
The Kodak Register Punch was listed in the "Kodak 1981-82 Photographic Producte Reference Guide" for $300.00 to give you some idea of value a few years ago.
Yep, you can. You can also buy pins for the Kodak punches. I have the same punch. De Vere 504 carriers use these Kodak style pins, although they use only 2 of the three holes made by the punch. I have the same punch mounted on a thick acrylic board.
That is the large pin bar and punch which was used extensively in graphic arts work for all sorts of things. Pretty much not done these days.
For small vacuum frame work Kodak made the far better LP (Low Pin) register pin bar and punch system.
The LP miniature pin bar register is the set to have for vacuum frame use.
I have a set of these Cat 302 6994
Designed to work with film as small as 4x5".
