Re: dots around negative space while printing

Looks like not laying down right. Is that the only color it does it on?

What anilox? Might be to much ink going on?

Blade or 2 rollers?

What type of plate material?

Any chance of any dryer blow by?

Re: Odd setup

It is hard to figure out at 1st.

But if you use a tint block sleeve or flood coated plate and play around with it, you can get the hang of it

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 ...

Re: Seeking Guidance on Eyemarks and Water-Based Flexo Inks

I have doubts that water-based ink is causing your problem. Can you describe the problem in a little more detail? Are you having color-to-color registration issues?
