Need Coating recommendations on UV Prints.

[enes sonmez]

Hello.
We have been using Vanguard vr5d more than 3 months already. I have 2 CMYK +1 white ink.

I have been dealing with scratching issues since the beginning. Finally I found out clearjet spray laminations. I used them on my recent projects. And what happened ? All my inks got chipped and came out. I did not realize that it is a solvent based spray.

So my biggest question is how you protect your projects. Especially if they are printed on acrylic or even ACM material. I don’t want t use my laminator since I have a 3 printers and got the uv as a replacement of them.

The recommendation can be either rollable or sprayable.

Also Can varnish ink helps for the same purpose and worth to spend 10k and install the varnish head on the Vanguard vr5d flatbed printer ?

Thank you so much.

I am using Maribu Production Clear Coat.. Most coatings react with UV ink. I think they have a new version that works with UV ink

Try using an adhesive promoter on your substrate before printing.

You might want to consider some of Marabu's water-based coatings instead that are recommended for UV curable inks.

See the attached brochure.

Are you saying that Vanguard does not have a recommendation for your problem?
If the printer is 3 months old, ask the people you spent $100K with. They must have a solution.

do not get Varnish... are your lamps at 100% intensity / use OPTIX DA Digital Acrylic

Whether you're using a rattlecan or sprayer, you must lay down a dry coat, first. Maybe two if the project isn't too large. Once they're ready, coat in one direction, then criss cross it. You put way too much clear on and basically melted your inks. Been doing it this way for about 5 decades, even before digital printers were around.
