morse contact printers
I'm clearing out my shelves and I found three Morse contact printers I'd
like to get rid of. These are 10x10 units with 39 argon lamps in each. Each lamp is individually switched. Anyone interested? |

Doesn't sound like a boat anchor...sounds cool, other than the
unpleasantry of having to source and pay for replacement argon lamps, but the detail of circular placement and switches is something that would be a pain to implement. How about contact print internegs onto graphic arts film...that's slow, right? |

To slow it down for faster paper, one could always add neutral density
filtration between the lamps and the top glass. Simply putting cut sheets of tissue or even bond paper below the glass will work. "Richard Knoppow" I got one of these guys several years ago cheap because the owner had broken the upper glass in transit to a photo sale. I've never used it, there is no longer any paper slow enough. These were made originally for printing 10x10 aerial camera negs on slow contact paper like Azo. The lamps not only switch individually but in groups of ring shapes to compensate for the fall off from some wide angle aerial lenses. The civilian version has a nice stainless steel mask. I am afraid they are now boat anchors. |

How about contact print internegs onto graphic arts film...that's slow, right? If its as slow as contact printing paper it should work like a charm. The lamps are arranged with separate switches for each lamp for dodging but the lamps are also arranged with additional switches that turn them on or off in concentric rings. The 10x10 printer has 39 low wattage GE UV lamps. They are no longer made but can be found. The printer also has two "nite lite" white light lamps and four neon safe light lamps. They are beautifully designed and very ruggedly built machines but paper suitable for contact printing on them is simply not available any more (although I understand someone may have undertaken to make a replacement for Azo). I suppose one could replace the neon lamps with very low power incandescent lamps and use a couple of sheets of ND filter material on the diffuser to get the thing to work with enlarging paper. They are too beautiful to throw away. -- --- Richard Knoppow Los Angeles, CA, USA |

I am afraid they are now boat anchors. N.D. filters may work, provided they are effective for UV. Most paper has brighteners in it which glow from the UV. I guess _that_ could also be used as a source. In another post I made just now, but before reading this, I suggest replacing the UV lamps with very small nite-lite lamps. Using ND filters or tissue would then be a practical option. One can get suitable ND filter material from Roscoe in large sheets that are not too expensive. It may even be possible to get material suitable for making variable contrast filters. The very nice masking arrangement and ability to dodge by throwing switches would be handy for LF printing. I may have a shot at this for my printer. -- --- Richard Knoppow Los Angeles, CA, USA |

Platinum printing usually requires a very strong source such as a plate burner or not too strong daylight, similar to printing out paper. The UV sources in the Morse printer are about 4 watts each. They were designed for short printing time on paper like Azo, not for printing out papers. Have you actually used a Morse printer for Platinum? -- --- Richard Knoppow Los Angeles, CA, USA |
