WM black cream

[mpot]

So we have some WM Plastics "black cream" and for a dark color it seems real sticky and thick. Is it just old and time to get rid of it or is this a characteristic of "black cream"? Or does anyone even use this?

It gets runnier when you mix it up and start printing.

Same here once you start printing with it, it gets real creamy just like it's name....I use it all the time, matter of fact they have a sell gal of bright white and black cream for under 80 bucks.

I got a sample of black cream that was heat damaged, and even stirring it up it didn't really print too well--added it to some too-runny QCM from the not so good QC days, and it was a great little bucket of ink.   

I really like their spec black, but you almost have to cut it a bit with base or reducer.  The bright white isn't bad either, probably gone through ten or fifteen gallons.
Seems to be decent ink for the money.

If I can get another gal of bright white just like I got now, man I would be happy this has been the best gal yet, can't say that about the last few gals.

Not sure if this will help, but I had issues a few times when people were pulling ink from the top of the bucket without stirring--the top prints easy, but has crappy opacity, all the pigment drops to the bottom, so once the liquid on top is gone, the bottom is opaque, but stinks to print.  That ink is so loose, I think you HAVE to stir the whole bucket up. 

If stirring well isn't SOP every time, try it out, it might help.

Thanks I'll try stirring more vigorously and see if it helps.

As an FYI ... a properly dispersed plastisol SHOULD NOT separate.  Seriously, you should not have pigment (TIO2 in this case) separating. 

Now stirring ANY white ink is good practice -- to break down hte false body (viscosity) NOT because the product separated.....

[ScreenFoo]

That's interesting--perhaps I shouldn't have said pigments settling, as I have no way of knowing what's making the bottom thick, but it does feel like it has a heavier viscosity on the bottom than the top.

I've wondered anyway, what makes something as heavy as titanium dioxide NOT settle.

I use Black Cream and love it.  Best black i ever used.
