Still, it may have been Silkscreen printed. Any of several techniques could have been used that could hide mesh involvement.

A colleague told me that when he found out that the unloading rollers on his Lotem became sticky, he was under a production bottleneck and couldn't stop the machine. So he used Heat Shrinkable Tubing onto a roller and it saved his day...

Old Dolevs and Lotems suffer from rubber rollers melting into sticky messy stuff. We regularly check for rollers getting softer. Stripping and redressing rollers is much easier before they start leaking...

Why are you retiring your Avantra?

Look if you can find a filter in the beam path. If you find one - try to remove it an expose a test film.

My observations/comments are probably obvious enough and I an not familiar with this machine, but anyway: It could well be a failing component on a board that passes the initial test but overheats and later fails. I usually start troubleshooting by unplugging suspected boards, cleaning the...

Screening is visually least noticeable around 45° angle. LPI and mesh should go hand in hand, choose combinations from mesh manufacturer tables.

Which reminds me of the case in the late Nineties, when I was contacted to advise on improving the print results of a brand new web offset press. I spent a couple of hours by the press reading color bars and indicating shortcomings, but the press operators couldn't get the press to print an...

Perhaps you should look into appyling the glue by Silkscreen printing.

Perhaps the ink is too "long"? In the sense that it slightly increases dot gain.

Perhaps a practical, handy solution is to turn that old PC into a Virtual Machine and run it from within a new, powerful computer. One caveat - some dongles are not recognized...

This reminds me of an obserbant customer who told me once, after watching how we fixed his problematic job that although he comes from a different industry (Electronics) he realizes now that we share much the same difficult situation because in both our fields "sometimes to achieve 10% higher...

Some, I agree. But for the rest - I'd much rather deal with the equipment...

This reminds me what a large printing plant manager told me many years ago: "To succeed in this business you need 3 things - Work, Equipment and Workers. You never have them all at the same time."

Outer diameter on my refurbished rollers is 30.4 mm. I bought some replacement Posi-Drive Belts from https://sdp-si.com/ There was no mimimum order when I ordered, all went fine. Good luck.

These rollers can be recovered by a rubber rollers resurfacing company. We have done that repeatedly over the years because when this rubber gets old it softens and finally melts. Messy stuff. We found IPA is helpfull for cleaning. Try finding a local service provider. Concerning the chains...

Up to CS6 Adobe sold perpetual licenses, AFAIK later versions were subscription only.

I think a reminder is due here: Anyone who can make do with the old versions' functionalities of his s/w, should create Virtual Machines of the older computers and thus, can keep on using these computers as VMs and keep using for as long as they like. If you don't REALLY need the MODERN...

Yes. That is a practical solution for keeping smaller temprature deviations.
