Exposure Units

<< < (3/5) > >>

Evo:
I've used everything from a very small fleuro tube unit up to to a 6' x 8' vacuum table with a 6k lamp. I now have a MSP 3140 and it's a dream. Most any good point source unit with a metal-halide lamp and an integrator will make things faster and easier. The difference in stencil resolution is like going from an old black and white tube TV to a new 1080P plasma with a Blueray player.


Other things to consider whether buying new or used:


PARTS. Are the blanket, controls, lamp, hinges, springs etc all good quality and easy to get parts for?

Is the lamp easy to change?

Does the unit have a memory feature to program different exposures?

Will it fit my current frame sizes that I commonly use AND the maximum frame size I can fit in my press?

I used to use carbon arc in the film projectors as a film projectionist back in the day. Brighter than a million suns. I can retire someday with all of the movie posters I have from the 60's-mid 80's (I'm not that old btw)

Tidbit. Does anybody realize that a typical film is about 6 reels long? That little black dot in the top right hand corner means it time to fire up the other projector. The second dot a few seconds later means it's time to switch over. Then we reload the projector all over again with the next reel. The audience never knows it.
Too this day, that dot stands out like the size of the moon to me when I see a movie.

Haven't they gone digital now?

This is waaay off topic but I haven't had a chance to talk about this forever

We knew when to start looking for the dots when a bell on an arm against the film reel dropped when the reel diameter got to a certain size as the film ran through. Very low tech but brilliantly simple.
Film was loaded just like teachers used to load class films before the video machine came out. Projectors were about 6 feet tall.
Some theaters had a platter system where the individual reels were all spliced together to form one big reel that layed horizontally. Then separated into reels again for the next theater.
I'm not sure how they do it these days. Must be digital.
