Any PRINTERS out there?

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

Any PRINTERS out there?

Postby chris69 » Sun Jan 25, 2015 5:41 pm

Hi,
here is a question for the printers out there. Am sure we have one in the community.
I bought a rail car for the larges side of my collection. The print on it is done with the
UV Label printing method. No solvent in the paint, it is set with UV light and it is
printed directly on the plastic. Now my dilemma: How do you get it off without damaging
the plastic? I tried Brake Fluid,Rubbing Alcohol,Lighter Fluid.....nothing.
What work is Acetone but it immediately attacks the plastic.
There has to be a liquid out there that dissolves the paint, after all they have to clean the printers????????
Ready to try anything..........
Thanks guys.
Happy Sunday
Chris

Hi Chris,

How about a very mild abrasive as opposed to a solvent?
kind regards,
Mark

Chris,

UV labels are generally the deposition and setting of plastic, so it's not surprising that acetone works and also eats the plastic model.

First I'd try is a citrus concentrate cleaner or a product like Fantastic. It is sometimes surprising what they will remove( even layers of vinyl coating). They are pretty benign to people.
Next I'd try a magic( brand) eraser. These are available in art supply stores. Go gentle.


You mentioned rubbing alcohol as not working. That means different things around the world. In some places it is isopropyl, some places it is an ethanol cocktail with acetone in it.

In the USA, it is generally USFDA Formula 23-H (8 parts by volume of acetone, 1.5 parts by volume of methyl isobutyl ketone, and 100 parts by volume of ethyl alcohol). It contains 87.5-91% by volume of absolute ethyl alcohol.

I have seen that rubbing alcohol dissolves the labels. It's not clear which type of alcohol it is, though.

So I'd try isopropyl, Methanol, and even ethanol ( whisky)

If those fail, I'd try finding the 23-H variant ( MSDS sheets will tell you and are required for all products) and boosting the acetone quotient a bit- maybe try boosting the Ketones, too. If you are lucky, you will find a blend that works on the label and not on the model.

If you want to continue the mad scientist thing, try the brake fluid with some acetone.

goo-gone in the US has Nitromethane in it which does not seem to harm plastic but really gets labels off.. Some of the CA removers also use nitro. Seems to work well and is water soluble. Always test any solvent on a part of the model that doesn't show first.
