LVT's unfortunately all need ageing computers to run them. While an imagesetter can deliver several thousand dots per inch, the screen patterns they use will usually output something in the 200-300lpi range or stochastic micron equivalent (on average - some might be willing to go a bit higher) - thus about 400-600ppi equivalent - LVT's usually output at 2000ppi-4000ppi range - thus you can do the maths for subsequent optical enlargement from that. They date from an era when you'd drum scan your original, do the digital retouch work etc, LVT output, then darkroom print your final prints (i.e. they pre-date the Lambda and those type of machines).
