Title: Printing HD with regular plastisol
Post by: Maxie on September 05, 2017, 06:21:06 AM: I have a job to print with white HD, screens ready but none of my suppliers have HD ink.
(In Israel it takes about 3 months if they run out, they have to ship it from the USA)
Is there any way I can get a HD effect using regular Plastisol?
Maybe some additive, puff, clear base?

It works even better if you have a short bodied ink to begin with.

Depending on the amount of blowing agent in the ink you are currently using, I might add 2%-5% puff to help with a little bit of loft.

Cabosil is the trade name for Fumed Silica, a 'universal thickener'.
It is an extremely fine white powdery substance (under some lighting and film stocks, it can show with a slight blue tint).
It can be used to thicken Resins, Adhesives, Silicones, and basically any other liquid substance.

And, it's even available from Amazon

Or breath in any of the powder once it gets in the air, which will happen no matter what you do.

Think of it as a desiccant - it will make water dry ;)

So, if you get any in your nose/mouth/mucous membranes - they WILL DRY OUT.

When I stir some into a quart container - I will always walk backwards - away from the tiny cloud that poofs out while mixing.
