Cold Light

Hi,

Going to a neon light manufacturer, what color should the light be for a cold light head?

And for VC paper what would the two colors be? Light yellow and magenta?

Thanks,

Jacques

Hopefully someone can answer your question better, but for variable

contrast paper you want blue and green light. The reason one uses

yellow and magenta filtration is that they block blue and green light

respectively. I can't comment on the suitability of using neon light

for enlarging purposes. Good Luck!

As mentioned above, for VC heads you´ll want blue and green tubes,

since this are the colors hi and lo contrast layers are sensible to.

For non VC heads, you´ll want balanced blue and green, unless you

want to print in graded paper, in which case any reasonable white

tube will work.

Don´t know why exactly you are going to a neon manufacturer, since

spare tubes are available for most cold heads.

hi jaques

just to add to what enrique mentioned .. if you have an older

aristo head ( for example) they will put the modern v54 tube in it

and make whatever modifications to the heater unit for just over

$100 ( us). i am not quite sure about their multi-tube heads .

i am sure that aristo could give you better information than me.
