That is an awesome design! Way more high-tech than ours. I am going to talk to one of our engineering students to see if he can build something similar. Thank you so much for your help!
Interesting! I did not know that solvents outgas downward. I have attached a picture of what our drying chambers look like. We have two huge floor fans blowing up from the bottom. That may not be the best solution if they are outgassing downward, not upward. We are looking at getting a box fan...
The polycarbonate is not the problem as we have been using this long before these issues started. The company I work for is not just a sign company which is why we can allow so much time for things to dry (but are fighting very much not to wait that long). We generally know what we need about a...
Has anyone else experienced the polycarbonate pitting? I have my assumptions that it is the ink because it shows up on the plex only where the ink is at. So, if we have a solid clear print with wording in the center the pitting will occur where the words are located.
I agree that is seems extremely excessive. But we have tried shorter outgassing times and they do sit in a dryer similar to what you described. Basically we have a drying chamber with a box fan on steroids.
We are having troubles with our translucent prints outgassing (drying).
We print with a Mutoh 1624 with ECO solvent ink.
From what I have heard, we lay down a lot of ink. We apply this vinyl to polycarbonate substrate. I have found the longer we let it sit before we apply it the more...
Yes they do complain that the colors don't match. Our oranges look red and our blues/greens sometimes look black. That's why i'm trying to fix the issues. I used to work on our graphics department but I am now a quality technician and have taken the task of making our backlits look much better...
Hello!
We recently (in the last 6-8 months) purchased a Mutoh ValueJet 1638 from a company that has never sold a printer like this. They specialize in more copiers etc. Anyhow, for installation they just brought it in, kind of leveled it with a construction level and left us. We have had issues...
That's sort of what I was thinking. I'd rather reprofile than spend $20,000 on a program that will do the same thing. Do you guys hire someone to profile your printer or is there a way to build profiles yourself? Our profiler is quite expensive... I'm just looking for options right now...
your...
Hello All!
So, I've been working with our graphics team to try to better our backlit ad application process. I think we have the actual application part down but now we are struggling with our ink levels.
We lay down our ink quite thick on our backlits which makes them take forever to dry as...
yes! that is a problem that we have... our oranges look red once they are applied, greens with look black, as will blues..
I did a test backlit the other day where i printed 2 layers, one clear 2nd surface, and one translucent 2nd service and it look so much better! the colors stay consistance...
Is this a practice you follow? If so, do you have problems with your white translucent lining up with your clear? I did a few tests a year ago and our problem was that the vinyls appeared to feed at different rates and the translucent would be an inch (give or take) longer than the clear but...
Yes! I have been trying to get them to agree to this for a very long time. Because I did do some tests and it looked so good! the colors look the same in the day and night and you're right, less vinyl!
i think it's time to revisit this issue :) thanks!
Double Strike/Double Layer?
so on the prints that are double strike you are only applying one layer of vinyl?
We only apply to polycarbonate second surface. We apply 2 layers of 2nd surface printed transparent vinyl followed by a layer of white translucent diffuser.
I guess what I'm trying...
2nd Layer Backlit Application
I work for a company in SD and we use 2 layers of vinyl to get the 'right color' on backlits. The problem we have is when the backlit is not lit the colors look too dark (oranges look red, greens look black, etc)...
for those of you that use only one layer do you...
Hey guys!
I work for a company that makes aluminum ad panels and we have been having issues with our vinyl sticking to the metal. Currently we are using 3M IJ180C vinyl. We do many blank white ads and instead of painting them white we will cover the face with white vinyl. So the problem is that...
