We do both Commercial and newspaper work with our Luscher. Works great, very dependable, pretty fast, no complaints.

i do a few research and i think lusher used uv led's from company it's name is Nichia from japan
but i think this led's it's pigment point is 360nm not 410 you don't think this is be come problem is some plates types ?
second i read in forums in Ecuador there are 2 lusher machine and there are saying they have some banding problems .. what you think about this ? are you heard something similer like this ... ?
now i'm using basys CTCP and i'm work a chinese brand i want work on lusher also the same plate (cheaper) ...
give me your opinion ?...
another question how many resulation i have in lusher ?

[Joe]

No banding here in Illinois. :lol:

In the older models banding could appear if the site has too much vibration, for example if you have it at the side of the pressroom and don't have proper vibration isolation to the machine. The newer (just out) series 200 use a linear motor instead of a leadscrew so they're not as sensitive to vibration.
The diodes are Nichia, 405nm violet same as Agfa and almost everyone else uses. Except these are 140mW.
A conventional (UV) plate peaks its sensitivity at 370-380nm, but retains a lot of sensitivity (how much? maybe 80%?) at 405nm. So to expose with 405nm diodes, you need some more power than you'd need if you had 380nm ones.
