Title: ManRoland Rotoman Web Press
Post by: Joe on April 30, 2020, 11:33:04 AM
Anyone here running a press like this where you work? We are having a "new to us" one installed and they are about ready to fire it up and we need the files that are supposed to be added to to the plates for its registration system. All I know is it is small diamonds that have to be a certain size (unknown) and spaced a certain distance apart (unknown) and in a certain order (unknown). I kid you not that was the same info I was given so I guess my question is...is anyone running a ManRoland press with diamonds for the registration system?

When I worked at Williamson, we had 2 Man Roland Rotoman presses. Both used the auto-registration.
I can't find an image of it, but it wasn't diamonds, they were polygons and rectangles that were in a row. Each polygon is mapped to each color on the press. The first one is black, then followed by c, m, y and then any spot colors, then the last one is black again. The "eye" on the press lines them up to each other at press speed.

I'll keep looking to see if I can find an image of it.

Have never worked with one, but many years ago I plated for a Harris web, and it required those diamonds. There is a default set in Preps that works.

I can't remember the name of the system we used.

I would think that whatever system is on the press, the manufacturer would have the correct file for you to add to the sheet. Doesn't matter if it's diamonds or squares, it's whatever the photo eye and the software is setup to read.

Like I said, we used them, they worked great.

I have the ones for a Harris press. We have 3 of those presses. But the diamonds are bigger and in a different order and the spacing is different than the press sheet that we supposedly have from the ManRoland press. I mean I've heard we have that press sheet but I have not seen it yet.

David, did they look like the attached? That is the one running on our other Rotoman but the one they are installing now uses something with diamonds. It would help if I even knew the name of them.  :D

no.
Ours ran along the side of the sheet not at the tail or lead edge.
Looked kind like this screen cap as well as I can remember

Thanks David. That isn't the one though. I've suggested they need to get it from ManRoland. But no time for that now. They've been assembling this thing since last November and just told us today they want to run a live job next week on it. We're just supposed to magically wave our prepress wand and make it happen.

:facepalm:

do you want to borrow my magic wand?
I just got it out of the shop, it kept changing all of the colors to something the custy didn't want.


it's all fixed, magically.


:lmao:

seriously, I would check to see if there was any documentation as to what software was used on the press previously. I'm not sure, but I don't think what we had came from ManRoland. It was like a 3rd party setup.
Title: Re: ManRoland Rotoman Web Press
Post by: Joe on April 30, 2020, 01:08:27 PM
Documentation? What is that? :rotf:

I wouldn't be shocked if this was 3rd party too.

Probably still better than the time my old shop got a press from Mexico and everything, including the command center and all the buttons, were in Spanish.

It is not just colorbar, what about presets?
You need to know is it Pecom, the system that is running.
Rotoman is awesome press, super fast, I worked with it until year or so ago when we sold our web division.
I will look to see if I have some old templates and colorbars.
By the way, diamonds are typically for Tobias system on Harris and it differs greatly from Pecom.
Title: Re: ManRoland Rotoman Web Press
Post by: Joe on April 30, 2020, 02:23:57 PM
Yeah our other rotoman uses Pecom and uses the color bar I posted up above. Like I said they have been installing this press since last November and today it became an emergency. Agree about the rotoman press though. They are great. Much better than our Harris presses. I said earlier we had 3 of those but we actually have 4 heatset Harris presses.

We have some Mexican pressmen so it wouldn't be an issue here. :rotf:

We did not have diamonds on Roto, only on Harris webs.
Our Roto was 4 units only (4 top and 4 bottom) so our colorbar was 4 colors and compensation box.
We also had to use compensation boxes separately, Rotoman was old and it had hard time picking the box out of colorbar.

The press they are installing and rebuilding is obviously not new so I'm not sure what they were using previously. Supposedly there is a press sheet from it showing the color bars but I have not seen it.

WPC or Web Printing Control used to have Diamonds in different Sizes. They were bought out by Baldwin Technology.
(Baldwin Vision System Multicam Register marks)

Baldwin is what we used for our first rotoman. We'll try them I guess although I'm not sure if we are using them again this time or not. Thanks for your input.

The system is supposed to be QuadTech color control system. I have the documentation for the color bar but no file to actually put on the plate.

I wonder if you got one of Rotos from my old shop.

Could be. Not sure where it came from.

I have these, we have a quad tech system on our 2 Komoris.
Title: Re: ManRoland Rotoman Web Press
Post by: Joe on May 04, 2020, 01:46:46 PM
Thanks for that. Those might be them. Looks similar. I sent them to be boss to see if that is actually them.

Are your complete color bars specific to the Komori or are they just Quad Tech marks too?
Title: Re: ManRoland Rotoman Web Press
Post by: johnny_jay on May 05, 2020, 06:05:56 AM
Quad Tech - How many unit is your press? We mainly use a 5 color color bar. Our Komoris use Instrument Flight to read grey balance. I attached the main color bar we use (Orig). We also have a slightly taller 4 color color bar and a black plus up to two spot color color bars.

The 6 digit code is what they are named in the press's software.
Title: Re: ManRoland Rotoman Web Press
Post by: Joe on May 05, 2020, 07:01:56 AM
Thanks for those. The press has 6 units.
Title: Re: ManRoland Rotoman Web Press
Post by: johnny_jay on May 05, 2020, 07:03:32 AM
We only have 5 units so these may not work.
Title: Re: ManRoland Rotoman Web Press
Post by: Joe on May 05, 2020, 07:15:20 AM
The diamonds you sent yesterday are 6 color so I would think we could just replace the diamonds in the color bar with the 6 color one.

Edit: The one named 251508-Orig.pdf that you uploaded is 6 color so we can probably make that work. Thanks again.

Thanks. I'll keep that hidden away as that is what our Harris presses use but who knows where the original files are?
