OK, I see... In my experience you need to rip and expose at a higher resolution to get well formed 1 mil lines. Is 4000 dpi your maximum res?

If these are thin Black marks parallel to the direction of travel, they are likely caused by the heat generated when the moving film bends and rubs against rough spots on metal surfaces, such as deflectors etc. A large sheet of 7 mil film is rather stiff and when its' emulsion rubs against metal...

And than, I printed it again - in NEGATIVE! I am making a point, RIGHT?

Why not find that Buzzer and tame it first?

Quoting an Engineer Safety doc: "Note: The laser interlock system is equipped with a buzzer. If a failure is detected in the operation of the laser interlock system, the buzzer is activated and the laser is shut off." I would try to replace the Lotem Interlock Board located in the distribution...

The CPU is typically a generic SBC (Single Board Computer). It was not manufactured by Scitex/Creo. On most of them you can find the manufacturers' name/logo and the boards' model number/code. Use these to search for an SBC on Ebay.

I am not familiar with your processors' model, seems you have a "modern" interface on which you can read messages however, the basics stay the same: You should verify if the level sensor in the developer bath is working correctly. One way of doing that is switching the wires with the Fixers'...

Thanks Ulrich, But, if Illustrator saves history inside the pdf and that info is not available to us, then such behavior is clearly counter-productive. Beyond that, why would Acrobat strip any info "silently" when a file is simply saved AS IS? BTW, I believe Acrobat doesn't strip the native...

Whenever we produce a PDF that seem abnormally large, we re-save that PDF using Acrobat (no change to any parameter). In many cases the new PDF file size diminishes significantly. I have no idea why this happens.

I am not familiar with this type of equipment but the description may hint towards a Backlash issue.

"... Actually, we expected the CMYK 4 color rendition as shown on the Pantone Bridge fan book. We keep the original designers' PMS specification just because it's much easier to find that swatch in the fan book..."

Esko FlexoPerfection is very good for that.

Since the Xante unit is a toner based printer, it is not suitable. The AB Dick DPM unit is basically an imagestter exposing polyester plates. I am not familiar with that technology, other forum members may be able to comment from real life experience. Personally, I suspect that its' not capable...

No, this type of toner based printer is not capable enough to produce the high resolution and precision required for quality reproduction of such an intricate guilloche pattern. A film imagesetter (CTF) or a CTP device is required.

Practically, that's the best way to go. It's an old machine, new spare parts are not available any more. Used ones are hard to come by and/or hard to ascertain they are still working. Good luck.

"...it's my short term strategy sir, until I earn their full trust..."

"...oh, I see... If it's such a valuable box that is actually a collectors' item - I suggest you insure it appropriately and deliver it in an armored truck..."

We never had to resort to anything that drastic. Aligning the detector usually fixed problems. BTW, turning off the punches altogether may probably be done in the registry but I don't remember details.

Yes, you can do that via the Lotem software, but it may be easier to just unplug its' power cable.
