Kodak plates thermal direct

[Green Printer]

Hi Kevin

Do your require an MSDS sheet for the Sonora XP plate?

[Kevin@digiflex]

Sonora XP is an "article", so does not require an MSDS as would a chemical. I believe we may have an "Article Information Sheet", but that's standard for many plates/etc.

Do i need to keep the first 20 sheets out of the paper recycling bin? Will my paper recycler deduct from our scrape prices if I let the first few sheets in the recycling? I don't want to contaminate my paper for recycling.

[Kevin@digiflex]

Lol, no... there is no concern over that, and there is SO little coating that this has never been a concern for others either. The TD/Sonora XP coating is about 40% thinner than a standard plate as well, so there's less than 1g/m2 of polymer... even less when you consider only a portion of that is removed from the plate. We'd have less concerns about that being recycled in your paper than I would about your ink and fount chemicals that are present in much higher quantities.

Gentlemen,


Being a relic from the Stone Age, but one that keeps an open mind.

Since posting a RANT regarding OPD Plates, I have since found I was not correct,

in my defence I based my assumptions with my experience of Aqueous Developed Plates.


For this error I have been sentenced to - Levigate 50 Stones !! sized - Double Demy

My regards, Alois

Lol Alois - our competitors have done a good job in FUD marketing against us so it's a common misperception we fight against - you're not alone! In a process as complicated as the mechanical and chemical wonder of offset printing, people are (understandably) skeptical and reluctant of change.

However, to keep print cost competitive and in line with our environmental responsibility sometimes we need to try new things... or try old things again (with improvements of course!). As far as platemaking goes, eliminating the processor and chemistry is one of the few huge opportunities left.

Kevin.

Another question Kevin. Is the removed coating still able to cross link in white light?

That's an interesting question, and I'm not sure how to answer it except in theory. The little bit of coating would be mixed with your founts and ink when applied to the press sheet though. I would expect the coating particles to be broken up into smaller pieces by that point instead of being one homogeneous coating like it is on the plate. They'd be separated by ink particles and fount, lint, etc. as well. That would likely prevent any cross-linking that did occur from having macro-scale impacts.

I agree with Gordo. I have an account that I do the press maintenance for. This account is a mid size newspaper and they use the Kodak Non-process plates. We don't see contamination with the Nova Mild acid FS.
