Re: Using infra red dryers to dry water based ink

I've never heard this topic discussed. Most interesting. One benefit that occurs to me, though, is that IR heaters are one per station and used only when needed, whereas, in many cases, with blown-air dryers, there's one big heater for the entire system, whether you need all that energy or not. I wo...

Re: Cleaning dried UV varnish off of anilox roller?

That's tough stuff.

Try auto paint remover. I used to get it from NAPA.

Another thing that can be surprisingly effective is a pressure washer.

Do any of this at your own risk.

Re: Ghosting

Have you played with viscosity? I know it's not the best, but maybe in this case.

Re: Ghosting

I would experiment with volume and/or viscosity, with the idea being "how can I get those cells to replenish more completely for the next impression?" If I get lucky, while I may step away from volumes and viscosity standards I have established, I can manage them as exceptions. as long as ...

Re: printing issue in magenta plate

I've seen something that looks like this and traced the cause to the thermal/wicking processing of the plate. In this case, the edges of images on the plates had a duller appearance. The areas of duller appearance corresponded exactly to the printed defects. To me, the edges had less support and the...

Re: cutting blades off a roll

I agree with Gorilla. Buy them pre-cut. It is a far better way to go. The ends are perfectly square and flat, variation in blade length is avoided, time and material are saved, and other benefits. That said, since you have some on rolls, make sure to use good aviation snips, not tin snips, or a devi...

Re: Allstein Press

This past June 6, I "celebrated" 43 years as a flexographer. This is the first time I have heard of Allstien. That said, I don't know them all, so it's not an indictment against them. I had a look around their web site. One encouraging thing is that they are German machines. That usually m...

Re: Flexo spitting

Hello Yow, Most of the time that I, or my colleagues, have experienced spitting has been when the ink, especially UV, has built up over time on the "back" of the metering blade (the side away from the anilox surface). Until you find a more permanent solution, you might give the blade(s) a ...
