On press wash - I have some but I've never tried it on a real job

[Ripcord]

I have a sample bottle of Saati Remove PW9 and the instructions say that I can clean the ink up and resume printing again after it evaporates. It seems to leave just the slightest of a residue which I can easily buff off with a piece of a T-shirt. I've never used an on-press wash before but I've been interested in trying it. My question is, for those of you who use it, is there ANY CHANCE that this stuff might affect the washability of the prints done afterwards? I am ready to print a large job with a color change halfway through and I really couldn't afford to learn the hard way.

Maybe it's a silly question, but I don't want to ask the manufacturer because they'd just tell me to do a wash test. I'd rather hear from people who use the product. Has anyone ever had any problems?

I don't use that product but I would not worry too much. That small amount of residue will not do anything.

When I do ink changes I Goop scoop all the ink out.  Then squeegee the rest of the ink out of the screen until there is just a fine film of ink left. Then I use about 3-5 sprays of press wash and wipe with a blue shop towel. Then another 3-5 sprays and another towel. Then I spray screen opener on the screen and wipe with a 3rd towel. Thats it. Takes about 5 mins start to finish. Some times there is so little ink that I skip the second round of press wash. The key is to squeegee out all the ink you can before trying to clean the ink out.

I use on-press wash (from CCI) all of the time. Lots of color changes.

The biggest risk is getting transfer from residue under the edges of tape you may have blocking reg marks or unwanted parts of a design.

Always good to do a strike-off on a scrap before resuming. If there is enough left to affect the washability, you'll see it as a blurred print before you ever continue.

Sorry for being so close. I'm just trying to figure out what you have been looking at for all these years.

Xenon FSIC is the best color change chemical I have seen.  De Ink. De Tape. Spray. Wipe. Re Tape immediately. No Residue.

Make sure you start your run (ink color prior to color change) using the lightest color first.  For example, color changing from black ink to white on a screen can lead to potential issues. 

I have used a good bit of color change brands and for the most part they are the same.  Once you are done with one rag/shirt just run it through your belt dryer to cure the ink and you can use it again for another task.  We will actually be switching to Plastisolv 810 this month from Easiway.  This will make us all Easiway product.  Both this, Rhino, and a few others are about the same price.

Also, when wiping down the bottom of your stencil make sure you double check for "stains".  Many times a little bit of the ink you whipped around will remain under the stencil and transfer to the next garment, especially if running a white or very light product.

I would strongly discourage you from doing this.  The chemical will burn off with possible air quality issues.  If there are no chemicals used and the ink was wiped off with a dry rag sans any chemistry then you should run the rag down the drier as this is the legal way to dispose of plastisol ink.

Great stuff... Needed this laugh this early in the morning!

Thanks for the replies. I also like Easiway products; I use 201 as my ink solvent and Supra in my tank. What I like most about Easiway is that they publish a lot of information about their products and their environmental compatibility. I have the Saati press wash because I got it as a sample but I can't find any information about anything Saati makes, other than the chemical names of the products, which is of some help but I want to use products from a company that has representatives who are knowledgeable about the products and approachable for inquiry. I called Saati to ask about their dip tank chemistry and all they did was forward me the MSDS. I don't want to use something in my shop if I can't even find out what it is.
