Kodak Linagraph 622 photographic paper???

Hi dears, i recently purchased a vintage roll of kodak linagraph 622 paper. It is a roll of 200ft and it is 35mm wide. The box is still sealed and before i start experimenting with it i’d like to know what it was originally made for? I can’t find anything on the net about it. The width suggest paper negatives but if so i wonder how it was used, what kind of camera etc…
Any thoughts?

Probably for printing Linagraph/Shellburst films onto? I have some EK Lina/Shell film, but mine is 70mm. I think the film was used in high-speed cameras for photographing weapons tests, which were then contact printed to paper, and analyzed frame by frame to see the development of explosions over time. Mostly just spitballing here, but I do have the 70mm film...

Interesting! I never heard of shellburst film. Thanks. I will do some research.

Thx Matt, i still hope someone knows what this paper was originally made for. Indeed i find Kodak Linagraph shellburstfilm info and even Kodak Linagraph direct contact paper info but this is neither film nor direct contact paper. I guess i will start experimenting with it.

Shellburst film was for distinguishing explosion plumes from the bright blue sky. The emulsion is thin, it develops low-contrast. I had Linagraph paper before - it developed low contrast in Dektol and I never tried it in lith developer (which is probably what was intended).

Hi Don, i get it for the film but I’m surprised to hear that kodak (or any other major company) would have developed a paper specifically for lith development. I though lith is an alternative process to achieve particular image characteristics invented by darkroom experimentation and as such not really supported by the industry. Correct me if I’m wrong.

First of all, welcome aboard.
As to the 'lith' aspect - please note that lith developer and lith film are originally intended for extremely high-contrast, 'binary' image-making. Originally, this had nothing to do with lith development as we know it now, where the effect of infectious development is exploited. We now call that latter process 'lith' because typical lith developers using only hydroquinone and a minimum of sulfite happen to exhibit this infectious effect. It's however not how the product was intended to be used originally.

Lithographers made negatives for "burning" plates, which were then used to print text and dot-screen photos on to paper. That is how most newspapers and magazines and books are made.
As @koraks posted, the extremely high contrast processes had unexpected consequences, which were discovered long after they were created - if the developers used were highly diluted, you could use them to try to encourage certain papers to behave very strangely - with patience, infectious development sometimes happens.

Hello Vincent, welcome! I received some of this paper around a decade and a half ago and, like you, found very little information about it. The links I found are both Linagraph papers, but different Type numbers. My paper is different again from those in the links below and yours, also, but the comment section of Richard's blog and the data sheet found at my local museum each provide some clues as to the papers' usage. Richard used his in a camera to make paper negatives and I used mine beneath an enlarger (I didn't know about paper negatives back then).
Anyway, I hope you might glean some small insight into its original use from the only two sources I found about Kodak Linagraph Paper:

Like @koraks already indicated, I meant in a high-contrast developer - probably high speed and maybe even higher temperature. Paper virtually identical to that paper was used for linotype machines, also, which were meant solely for high contrast enlarged typeface.

I tried some of the paper I had in an old folder, on a 120 spool, because I determined it was quite fast.

I think I still have a 5" wide roll of it somewhere....
