Canvas UV coating.
« on: October 19, 2023, 10:18:20 pm »

OK so I am printing on LYVE and love the canvas. It's coating it I hate. It looks like a bad amateur finish that always reflects light. I am spraying it and it looks even but it's like shrink wrapping the art. My images are 90% black and Lyve has helped me get blacker blacks than any other canvas. I've tried all three finishs(matt, satin and Glossy from BC) Just want some way to coat them you don't see at all. It looks like my dad's 80s midwest studio when he sprayed prints and they looked it. I just want inky blacks.....Thoughts.

A very thin layer of coating, is that what you want? Solvent based spray varnish with satin finish may work.

I will try a thinner coat but the satin from most companies has some mica in it and it reflects light. Really want the feel of paint on canvas not a car finish.

As Kang-Wei said, thinner coat. We don't coat ours too thick for the same reasons you mention. I find that mixing the Matte and Gloss gives a better Satin than the satin, and add just a little bit of water and it goes through the HPLV sprayer better, and helps it from getting too thick on the canvas.

Agree with all the light coats. We spray hundreds and a misted light coat one direction. We let that dry. Then the same light misted coat the other direction. Comes out perfect every time.
The reason we let that first coat dry before the second is it accelerates the overall drying time. If you spray the second wet coat right on top of the first coat you will extend that dry time.
We are using Binks HVLP, the same equipment we used in our custom cabinetry business. Turn that nozzle down.

Try BCs 17M and see if you like it. Otherwise you'd have to use a solvent spray like Moab, Hahnemuhle or Print Shield as none of them will affect the appearance of your print. This is what I do.  But you have to stretch the canvas first before using a solvent spray as they are brittle and can crack when stretched, and it requires GOOD ventilation as they really stink and are toxic.

Hahnemuehle Varnish Matt produces a really matte surface. When my dealer started to import Breathing Color's products  to Germany, I tried their matte varnish for comparison. BC's varnish applies some kind of lustre sheen onto the surface which Hahnemuehle doesn't.

I speak of the varnish - Hahnemuehle Protective Spray reacts as mearussi says.

After reading this I bought a bottle of the Hahanmuele Matt yesterday. Might as well use watered down white paint. It's super thin so tough to spray evenly. I then tried rolling it on and again, it looks like you brushed on a very thin layer of white. Nowhere near the blacks of BC. I am mixing matte with just a little satin and liking it even better.

If it is tough to spray you are applying too much. Light mist coats are what you want, they will never run. Any matte product is full of silica to dull down the sheen. Big problem is that it destroys the clarity.
Get too much on and it is like looking through wax paper.

Hm... Some things come to my mind:

1) Sure you mixed up the content of the bottle thoroughly? I once wondered why the solution had become so thin, until I realized some of the material had sunk to the bottom of the bottle - and stayed there :-)

2) Yes, the "lustre sheen" of BC's varnish makes blacks look deeper - but I understood your first post as a search for a really matte surface.

3) I roll varnishes, never spray them. For this purpose I use two rolls - one to apply the varnish, another, clean one, to remove excessive material after 3-5 minutes.  The white appearance of Hahnemuehle 's varnish disappears with that second roll, at the latest after drying. As you mentioned buying the bottle yesterday - how does it behave after drying?

4) The canvas I use is Canson Museum Pro Canvas Matte - perhaps the varnish reacts differently on BC Lyve...
Just my 2 cents.

5) Just found this post of yours - so I think you would not like the "dead matte" I like about Hahnemuehle's... Sorry if I pointed you to the wrong direction.
