T-shirt printing

Tuesday, July 14th, 2009

I’ve been experimenting today with block printing directly onto fabric, and it’s come out pretty well. I used my cartouche block, with the same printer’s ink (incidentally, using a 1lb tin and a spatula instead of a squeezy metal tube makes things quite a lot easier) and a metal spoon to make sure the ink penetrated right the way through the fabric.

This stuff has proved far too tenacious to wash out of paper once it’s dried in, so I’m hoping it’ll be the same in a normal wash – obviously, I’ll do a test wash first rather than putting it in with my good shirts!

The only problem with the setup I was using is the difficulty of keeping the fabric away from the block once I’ve done the transfer and started to peel it off. The way I set it up was to turn the T-shirt inside out, lay it on my worktable with the label facing down, lift up the top (front) side, and slip the pre-inked block in before letting the fabric down slowly and smoothing it out as I went. That part worked out pretty well, though next time I’ll probably use some artist’s tape to stiffen the fabric around the printing area first.

Another way to do it would be to lay the block down first as normal, then lower the fabric onto it with something inside the garment to stiffen it up and stop the ink from transferring right through. Rubbing it through both layers probably wouldn’t work well, but given that the ink glues the substrate down very effectively it would be extremely easy to turn the T-shirt inside out around the block.

A third way, of course, would be to lay the T-shirt down right-side-out and front-up, and then lower a vinyl block onto it. Whilst I haven’t tried printing this way yet, the vinyl is flexible enough that it should be entirely possible to rub from the back of the plate rather than the back of the substrate.

It did turn out that I could have done with a couple of extra hands when peeling the fabric off the block, but stiffening it up (ideally I’d use a tapestry frame, but finding one large enough to give enough clear space inside but small enough to fit inside a T-shirt and get a decent grip all around might be problematic) should deal with that one too.

Gramarye

The design and text are screenprinted, the frame is screenprinted and then overpainted to give the broader deckle.

For this one, I made a screen framework from scrap mountboard and stapled the screen onto it. Note to self – do not attempt to block it out in the same colour as the sharpie you use to draw the text on.

I used another scrap of mountboard for a squeegee – oddly, it’s remarkably difficult to find an actual squeegee around here. I’m sure I remember seeing them in all sorts of places, but when I’m actually looking for one…

The printing process went well, and it gave quite a lot fewer artifacts than the stencilling did. (Though, to be fair, that might also be down to taking more care over blocking it out.) One thing I did see was a set of blobs on the right-hand side, just outside the frame – that’s the other reason I overpainted it, of course.

It’s hard to make out with my crap photography, but there’s an interesting 3D effect on the second half of the text – a grey drop shadow to the right. I’m not sure whether that’s down to blocking or lifting or driving paint underneath, since I was standing on that side and spreading paint towards me.

T-shirt stencilling

Friday, June 20th, 2008

I made this the other day – Sainsbury’s sell fairtrade cotton T-shirts for £3 each. Still horribly ecologically damaging, but there aren’t really any practical alternatives to wearing cotton. And cheap, so I picked up some to experiment with.

(I tweaked the brightness and contrast a little, to adjust for the domestic lighting and make the pattern more visible.)

Following a friend’s suggestion, I made a screen from net curtain fabric (£1.50 a metre from Walthamstow market) and spread it taut on my tambour frame. Some viscous grey acrylic worked nicely to block it out, after drawing on the design with a Sharpie (note to UK people – you can get authentic Sharpies at Ryman’s, and they are indeed as good as people say).

I mixed up the paint, using 1:1 acrylic paint and textile medium, but managed to overestimate and dish out far more than I actually needed. I ladled it out with the brush and vigorously rubbed it in (with the same brush – this makes it, technically, stencilling rather than screenprinting) going over and over in several patterns.

The first layer – the gold – went on nicely, but I didn’t have complete coverage. Some areas of the disc were a bit patchy. I ended up taking the screen off and hand-painting over it, since it was such a large area and no fiddly bits to deal with, and deliberately doing texture effects. I’m not sure either way about the rough, frayed edges of the disc – I rationalise it by thinking of it as deckle.

After leaving that to dry for 24 hours or so, I put the second screen on (the first was a simple circle) and repeated the procedure with the blue. This time it didn’t need overpainting except in a few small areas – I didn’t want to risk putting the screen back down and ruining the registration.

I’m rather fond of the distressed print effects and broken lines, and I’ll freely admit to being a sucker for this particular colour combination.
