I'm trying to print on unstreched gessoed canvas and for some reason not enough ink goes on it, it seem to print only on the "peaks" of the canvas. What could be the cause? I get an OK print when I pass several times over but the ink then smudges so I lose a lot of details and it becomes too dark.
Could my mesh, at 245, be too dense?
I use TW5102 waterbase clear base with some TW5018 Black in it. I was planning to use the same mix in layers so it would get darker and darker each time...
If you have a coarser screen use it. 200. 160 if there is no detail or halftones.
make sure the screen is well tensioned
makes sure the canvas has a tighter weave
TW WB ink works good. I've used solvent based MP, and satin poster.
Round your squeegee a bit, or flop it over more than normal (you risk bleeding, but you can get it on one stroke)
if the ink is transparent, you are going to see the tops and the valleys on the fabric because the trasparent ink pools and gets darker in the troughs between the weave in the canvas. Opaque works best.
You said unstretched? D.D. was talking about the stretcher bars on a mounted canvas I think.
Thanks Andymac, I will try the above. I'll go opaque but I will have to go house paint 'cause I don't have TW white ink... And 245 mesh is all I have so I guess I'll have to go real slow when squeegeein'...
Also, what is backer borad? Sorry for the maybe dumb questions, I'm fairly new to art printing. I use to do very basic t-shirts but that's all. I'm learning all this as I go, setting up in my small 3 rooms flat, hoping I can reach a tight deadline...
Anyhow, thanks for the tips! I'll be back for more...
i have someone asking about canvas printing, and that isn't my usual thing. the answers above seem like a good starting point, but here are some more questions:
- does it always have to be gesso'd first?
- should the ink be a different consistency than what would normally work for poster (uncoated paper) printing?
- am i asking for trouble with a 300 mesh screen? i'm worried to go lower because the artwork involves small-ish text.
- anyone have a good online source for canvas? (mounted or unmounted...not sure what the client wants yet.)
