Re: Keep inks cool

Hi longtimefan Okay I see your setup. If you want a quick fix until your permanent solution comes: get a thin flexible hose, work off a nearby chilled water line and wrap it around your ink pot. If 1 works, then T off 7 more. Something like this could be done and tested in a day. The team's not goin...

Re: Glossy Solvent based black

Hi FJSmith Presuming it's surface print because reverse print is always very glossy if it's glossy film. (Don't let me go on about how we had a customer with a job on matt film wanting a glossier finish and to match the Coated Pantone book.) It seems your ink supplier would need to formulate a "...

Re: Keep inks cool

Hi longtimefan Why do you want to keep inks cool? For solvent evaporation issues? I've seen on a long-run with small coverage (and specifically CMYK inks) that when you open the lid after being closed for a long time, a misty cloud has formed in the ink pot. Pretty cool. If you're really trying to d...

Re: Bearer Bars

Hi all We ran a trial a while ago: This job had excessive bounce. It only had 2 or 3mm wide bearers, and they were half-tones. We re-made the plates with 6mm bearers, and converted it to full solids, and it didn't make any difference. Couldn't increase the speed and at the same speeds, the vibration...

Re: Tips/Tricks - Flexographic Mastery.

Sometimes when we need to pump up a pot of solvent (E.g. testing a pump or something), you can put a dirty anilox in. Then take a sponge/rag/brush. And while the anilox is rotating with solvent, you can clean it. It's basically like submerging the anilox in solvent. Of course this is time consuming ...

Re: anilox delam (inner core)

Get a quote on re-doing the anilox but it is probably not worth it to re-build it. Rather order another new one. On the topic of keep the mandrels clean. Often times the less used station's mandrels get ink drops on it over the week. One way to keep the mandrel clean is to always have it covered. Yo...

Re: Tips/Tricks - Flexographic Mastery.

Hi longtimefan We don't normally work with Kodak plates, but I Googled it and it seems to mainly be for screens. This particular design is full solids. Hi Gorilla Well I'm always open to suggestions that we can reasonably trial the next time this order comes through. But I added it just as a note. I...

Re: Tips/Tricks - Flexographic Mastery.

Hi all On the topic of bounce, we had an interesting case last month. We had a job that was bouncing significantly (you could hear it was that job just by the sound and frequency of the bounce, and intensely feel the floor vibrating as well). The plate had multiple horizontal bands and thus design w...

Re: hand proofer to press correlation

Hi DasBoot To add on Gory's response: take multiple samples of multiple aniloxes at production speed and compare them. You may eventually find one anilox of your matches quite identically to your hand proofer (your hand proofer lpi probably isn't going to match an identical aniloxes lpi). But one of...

Re: Tips/Tricks - Flexographic Mastery.

On the topic of long-runs: the best for efficiency is (super obvious statement coming up), less stops. So prior to a long run all preparations are made: blades and seals that are still 30-40% life left, get changed preemptively. Also during the run operators and assistants co-ordinate knowing what t...

Re: Chamber with a third blade puzzle

Hi Gorilla I think I've mentioned it in another thread: The third blade is designed for higher speeds, less bounce and to reduce ghosting... Or so I've read. I've never seen it in action though. With speed and bounce, I think part of it can be reduced by design and in my experience ghosting was main...

Re: Bearer Bars

Hi Gorilla If there's no issues regarding the pinholing then yeah, stick to the softer tape and right plate. I wonder what would happen if you put an even softer tape with the GTT... When the ground doesn't vibrate as much and the sound is more pleasant then you're running it well. If they're happy ...

Re: Bearer Bars

Hi Gorilla Glad to hear that you got some good results on that. Normally when we go with a softer tape on a large solid; there's quite a bit of pinholing. So to combat it we have to apply more plate pressure; which in turn increases the bounce. Is the softer tape not causing much pinholing for you? ...

Re: Solvent based ink storage

Static requires motion to be generated and it's generated from the motion of pouring out the solvent out of the container. While I've heard about it I've never heard anyone with first-hand experience with a printing solvent being poured out and generating a spark (possibly because the quantity in mo...

Re: Selecting an anilox roll

Hi edpression Line screen The line screen of your anilox should be consulted with your plate maker. Depending on the screen ruling of your types of work, they will be able to advise you what screen ruling to go with. Also see with the sales/management/(whomever applicable) what kind of workload the ...
