POLL: Automated or Manual Two-Sided Proofing?

[Hopkins Printing]

How do you produce a two-sided digital dylux??

Anyone else???

We simply use cut press sheets without color match, and ink reduced on an older Epson 7800. We then manually flip the sheets and use the guides on the machine for registration. We can back forms up close enough for dylux/mock-up reasons. We do see some skew when two different operators load the different sides of the sheet though.

We had a HP DesignJet 1000 with a Techsage SpinJet 1000 attachment up until 5 years ago.
Now we have a Preproofer from Digital Imaging. It is 2 EPSON 9XXX stacked on top of each other, the bottom unit rotated 180 degrees from the top unit. The top unit is fed from a roll. It prints the sheet and cuts it. The sheet slides into the bottom unit as a sheet and the back-side is printed.

Sounds like a great setup in your estimation how far is it out of registration on the back up?

Usually no more than 1/32". But like all devices of this nature it has its good days and bad days.
The newer model is better because it uses a camera system for back-up registration.

We use an Epson 9800. If you know how to adjust things you can get pretty tight backups, within a 1/32" or so.

Please keep those replies coming. The more the better and thanks!

We use a Canon Impoproof iPF8000s to produce 2 sided dylux. Registration isn't normally an issue, but like any piece of equipment, it can have its moments. I would say 95+% of the time there is no issue. The time savings made this a no-brainer decision 3 years ago.

We also use a Canon Impoproof. We have just upgraded it to 8300s. If you don't use automated backup, you are really not checking your impositions.

We still use a HP DesignJet 1000 with a Techsage SpinJet 1000 attachment for some proofs. We also use an Epson 9600 for heavier stock mockups and manually turn the sheet.
