Envelope Overprinting

[ajr]

We are getting 4 envelope overprint machines installed shortly. I think they are Halm machines!!?!!. I will be making plates for them, I have been told they the images have to positioned in a particular way on the plates and the perfecting image is reversed. I was wondering if any one has got any detials on this or layouts they could send me. We are getting 3", 6" and 9" machines. Any help would be appreciated.

Thanks in advance

ajr we have a 2/color Halm Jet press that I make plates for on our PlateStream. It's 12" wide polyester material that I have set to cut at 19" length. If your machines are anything like mine you should have some pre-printed stripping sheets for it. Our "distance" to step 2-up on a plate is 9.488" that's the circumference of the cylinder. When I do a 4-up run the distance is half that at 4.744". and Yes when yo do duplexing it gets tricky to imagine having to plate the second side backwards, but here's why, normally the plate cylinder is right reading and it transfers to the impression cylinder wrong reading that transfers to the envelope right reading. What happens in the duplex is that one step is added so the image is goes from plate to image to bottom image to envelope, so you start wrong reading (plate) image (right) bottom image (wrong) envelope (right).

If there is anything beyond this I can help you with PM me and we can get together over the phone. Our Jet has been with us for years and anything I can't answer, the guys in the press room can :wink:

We recently purchased a jet press as well.

As far as imposing for the press I created a template at the RIP that was the exact size of the plate - place 4 "image' boxes on the plate;
+----+
| |
+----+
| |
+----+
| |
+----+
| |
+----+

Then I just have my guys drop a on up image in the template and it spaces the run evenly on the plate. For the Duplexing I duped the template and reverse the image so it will transfer to the 'bottom' blanket.

Haven't had a problem yet.

When setting up the template it helped me to think in terms of continuous form-feed rather that sheet-fed.

Hope that helps some.
