Re: Two Sided Proofers
Hi, regarding distribution, I am not so sure about current situation with US Idistribution know their website needs updating, I know there are some installed in the US, as I installed one back in January.
The main difference are really at engineering support level but a quick run through:
Paper Shuffling to reduce skew, the paper gets shuffled so even if it is not loaded straight by the end of the load it is much closer.
Paper requirment is it can work with lots of paper types, even seen people using uncoated
Alignment of unit to HP is much better, Once set it is hard to lean on it and make it go out of alignment. Having worked with other systems such as doubleproof where this was a common problem, issue.
It uses foils which are placed inside the HP paper path (and easily removed) to allow better paper entry
From a technical side, it is super easy for an engineer to change any parts, which as it happens was luckily very rare.
The system used a USB system to allow easy changing of firmware/settings/testing motors. The main aim of this was to reduce install testing time. for an end user it makes little direct difference but this was a god send for people installing.
As far as speed etc, its pretty much the same, with the versojet you can programme the system to use what ever Paper Type in the HP control panel you wish
On the negative side: it looks industrial and is not as good looking as the spinjet. But I am pretty sure no one buys pre-press kit because it looks pretty.
Like other duplex systems, what workflow you have can make a difference, If you use a slow system then it can take
a while to print the first job, as the controlling software needs both sides of the job before it can process where as sending single sided to an HP it starts printing at the start of the first job. Creo Brisque systems seem to be very slow, where as Prinergy for some reason seem to be lightening fast. The system has been installed on a wide variety of systems
