adhesion

I've seen ton of discussion on printing on metals and acrylic but never on something that's painted with Matthews (Metal or Acrylic). We had mixed results especially printing something that has paint buildup like in case of ADA signs. We tried AP3155 with mixed results and it leaves a...

Whelp, I've been lurking these boards for over three years now. I figured my first post should be one of meaning. Well.. now it is. And I'm hoping one of you might be able to assist me with my own muck up. I work in a small sign shop and I'm trying to help a woman with a 8' x 4' metal sign she...

Hey guys I could really use one help right now. I have done HDU signs before, I’m having some serious issues with paint blistering when removing paint mask l. I am in the process of finishing 2 6’x8’ signs. In the center of the signs there is a large crest that Im attempting to gold leaf but...

We observed a change in adhesion in the last two month regarding extruded acrylics. We used to print 1% of LH-100 Clear Ink under our LUS-150 Color Inks as a primer and had really good results. After complaining for quite a time now one of the technicians told us that Mimaki changed something in...

I've had several installs where my vinyl lettering will not stick without lots of tricky holding and peeling of the transfer tape. My research shows this has been due to certain types of paint, color and paint off gassing. The vinyl brand I use is Oracal 631 and 651. I don't really have any...

I'm printing on magnet material with a JFX200 mimaki and get pretty good adhesion using Kolorcure primer, but when to go cut these magnets on our Colex cutter the ink slightly chips off of the edges. Are there any primers out there anyone uses that are really good or specifically for magnet...

Has anybody tried this stuff for adhesion to Coroplast etc? Feedback? Adhesion Promoters

Anyone do UV printing directly onto a white board?

Hi All, I'm new to the world of flatbed UV printing and I'm having a bit of trouble getting inks to stick properly to mylar films. Or, generically, polyethylene terephthalate (PET/BoPET). We have a new Mimaki JFX200-2513 which prints beautifully, but the inks don't stick well on these films...

I have a Mimaki JFX200 flatbed printer that uses UV ink. I'm having some trouble getting it to bond well printing on corrugated material like the material used for yard signs. I have 2 primers from Nazdar that I've tried that work great for most everything else, except it doesn't help bond to...

Good Evening, Curious if anyone has any knowledge of any particular digital ink that will work in a Ricoh Gen 4 heads? The current ink we are using will not adhere to the acrylic without requiring an additional pass of UV (cure setting almost maxed out). The white that we are using adheres...

Hey All! Just started at a new shop and they have a FUJI flat bed. It's an OCE just rebranded. They are having a problem with ink sticking to plexi glass. I never noticed a problem with the OCE at the old place. Plexi panels came and went very well. This particular job is a black text/white...
