Any question answered...

That’s closer to what will happen, but I was hoping for something more like this.

There used to be a solvent for solvent welding acrylic. Put the two parts together and the solvent would wick down the join and weld the two parts together. I can’t remember what it’s called though.

Didn't use the chez_jay method. Did 16ml down to zero of white, and reversed with black.

Hard to accurately measure with a Calpol dispenser. Weighing it might work better but would need sub gram scales for the amounts I'm interested in.

Ebony and ivory live together in perfect harmony
Side by side on my piano keyboard, oh Lord, why don't we?

Because grey is the future.

You seem to have accidentally proved the one drop rule.

Can we see the resulting artwork?

That looks better than superglue.

That looks like the stuff.

I've never really had much luck with super glue but that stuff dissolves the plastic and kind of melts it back together.

Sounds perfect. Does it change the colour of the acrylic around the joint?

Still a way off actually making art. But it kind of works.

Because it dissolves the plastic if you put a bit too much on it can take the shine away. But no colour change.

It is also dichloromethanol. Don't go putting it in your tea.

dichloromethane

FTFY

Also butanone (methyl ethyl ketone, MEK), although you're right to point out that the CH₂Cl₂ will probably be listed as the cause of death

I stand corrected - it is dichloromethane.
How come you know so much stuff?
What's your day job?
Just prying.....

How come you know so much stuff?

I know very little, I just knew that one because a: I used to use that cement as a boy building Airfix kits and b: I looked it up to check

Would you not just use 4 screen for something like that (C, M, Y and K)? Or am I missing something?

Someone who know more about printing than I do will be along shortly. but I'm not sure screen printing works that way.

You can make halftone separations of cyan, magenta, yellow and black and overlay to make a ‘full colour’ image. Just wondered if there was a reason you wouldn’t use that process for that particular image. I know with fabric you’re going to need a lower thread count screen so your halftone will need to be coarser too.

not sure screen printing works that way.

It can, but I doubt whether you could maintain consistent registration across the piece on a fabric substrate

You’d be surprised - t shirts are usually printed on a big carousel, where the shirt is fixed flat and then doesn’t have to move at all between screens.
I guess moire is more of a problem with multiple halftone screens, but you work all that out when you’re exposing them rather than at the printing stage.

That bit I'm not surprised by - I've seen the carousel. The fixed points will obviously be as rigid as the platen and it's supporting structure, but fabric moves in mysterious ways so while the sides are fixed, the middle can drift about a bit.
