The inkjet method sounds like it has reasonable cost. Maybe there is a way to use a laser printer. Thanks!

- wbeaty 10y agoBack in the old "Circuit Cellar" magazine era, they made a printer-hologram by photographing it onto film transparency. I recall that it was a "binary hologram" 300dpi covering a full 11" page, then reduced to a few-mms-wide patch on monochrome slide film. Obviously the main challenge would be in getting the darned thing in focus, so the fine pattern doesn't blur out into gray. Then, print out a feet-wide paper copy, so the pattern ends up as a few-cm hologram on your slide film.
