Hi I'm screenprinting from my backyard with a very DIY approach.

I had a search around and couldn't find any answers to this question although it seems like an obvious one.

Is it possible to fix an imperfection in a screen by removing just some of the emulsion?

For example can I put some bleach on a paintbrush etc and just dab a section of the screen, then blast with hose to get it off?

From an industry perspective this is probably not something you would do a lot. But for backyard screenprinters this would save a lot of time.

Or what about maybe using a fine needle? to physically poke out some of the stuff?

What do you think?

Hello,

I don't understand why you would like to remove emulsion? A small bit too much emulsion will not create an imperfection...of course if it's not a the printing zone.
To be honest i will not approach the silk with a needles.

I'm doing this in my backyard, exposing screens in the daylight, so there's a lot of variables and **** does happen.

In this case I had to stick two transparencies together and inadvertently left a tiny crack which has left a very fine line of emulsion in one or two places.

In a previous example I got a part of the image that was conspicuously too thin on the screen (sunlight bleeding under transparency probably).

Maybe you could try to remove the bad part with a Cotton Buds and Emulsion remover carefully.. it should work.

Here's a link to one of my e-lessons that will show you several ways to fix screen problems: http://endangerous.com/fix.pdf

Hey thanks for the useful link.

I was able to scratch the emulsion from the screen using a needle, I'm surprised I didn't try it before, was easy. This didn't tear the mesh but it did get distressed somewhat, obviously not for big errors but seems ok for dots, lines, small imperfections.

glad it worked, I use a spot remover gun now and then to blast out emulsion spots
