Discharge buildup on underside of screens
cclaud3:
Just a thought. We use the super 75 white as our discharge white base. Is there something funky in that base that would cause a buildup issue? If anything it has less white base. My understanding is that it is premix of brite white + brite base. We would use pure brite white but it's unusable without basing down without regular brite base.

Eric on here is the Matsui Master. We are all CCI. Two different inks.
ericheartsu:
wait are you saying you're using super 75 as a discharge underbase? Or are you using it as a base to mix colors? Either way, you should be using Binder 301, not super 75 for mixing.
Super 75 should be a standalone white DC.
cclaud3:
No discharge underbases. Using the word ‘base’ purely to reference the white and clear base references in matsui’s software.
We are using brite discharge base for the clear part of the regular discharge recipes. If white base is required in the recipe then We use super 75 in lieu of brite white discharge. My understanding is super 75 is brite white discharge mixed 75/25 brite white with brite discharge base. We have made a few formulas with brite white combined with brite discharge base as well.
We use super 75 as our white discharge as well.
So anytime white is requested in discharge recipes you use 301 dm binder? My supplier had said to do it as i am doing which is the reason for what we have been doing. The matsui desktop and previous software is so generic it says white base. The newer online version has Alpha trans white listed when white is instructed in the recipe. Please confirm when you have a chance.

On long runs the silicone spray seems to make the build up worse on some jobs that we've used it on or we have to replied to often which was a pain, flashing every color would be nice LOL but not always possible.
