Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
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.
Ok, I have received some official info on the recipes. I'm posting a summary of the response.Brite Discharge White is full whiteSuper 75 Discharge White is 75/25 Brite Discharge White/Brite BaseHM Discharge White White is less than 75/25 mix of Brite White/Brite baseAlpha Trans white is 60/40 mix of Discharge Binder 301 DM/HM Discharge WhiteTechnically any can work for the white portion of the Pantone recipes. Obviously the higher concentration of white the more sticky it will be.It was suggested to use HM Discharge white for white portion of recipe along with brite discharge base.Can also use HM Discharge Base instead of Brite Discharge Base or a 50/50 blend of these two bases.Use 10% quick additive. We have been using 6%.Can try additional 3% mg softener. But I probably will not do this in conjunction with 10% quick additive.Platens warmed at 130-140 F. We were close but a little over temp.Mesh counts 180-230 for Wet on wet. We were already doing this for screens to be stepped on.Slow press down to allow heated platens to dry ink between screens. Ok, we were running 350-450 hour as it was already.Double stroke with fast speed. Already doing thisSlightly off contact. Already thereSo the 2 main things of differences from what we were doing are HM white discharge for the white portions of the recipe and upping quick additive to 10%. Will be trying this.Again, their dated downloadable software doesn't even reference discharge. It lists stretch white & stretch clear for nearly every recipe. Quite confusing.The newer online software using alpha trans for the white parts. Confusing again as it's part of the alpha system. It was clarified that it's a 60/40 mix of binder & HM discharge white.Wasn't even aware of the 301 binder product.How in the world you are supposed to know this info is beyond me. Hope this is of use for anyone else.
Right here has been my reluctance to switch over to Matsui for our discharge. I've been wanting for years to use one ink company for all our water base needs but we are locked in with CCI for our own formulas. The Matsui Discharge and recipe line ups give me headaches. There are a few other companies out there I like as well from Aquo to the new whatever Zodiac / Wiflex is called but getting stock and answers and formulas is something else. It's almost 2021 and not one ink company in my opinion has a stable water base line up.
