The Physics of the Mesh

At its core, screen printing—or serigraphy, if you want to be fancy about it—is a stencil method. But instead of cutting shapes out of paper, we use a fine polyester mesh stretched tight over a frame. I coat that mesh with a light-sensitive emulsion, place my artwork on top, and blast it with UV light. The light hardens the emulsion where there’s no artwork, and the rest washes away, leaving a microscopic "hole" in the screen.

The technical challenge here is the tension. If the screen isn't tight enough, the image blurs. If the exposure time is off by even thirty seconds, the fine lines won't resolve. It’s a bit of a science experiment every time I start a new piece at Oli Fowler Art, and that’s before I’ve even touched a pot of ink.

Ink Chemistry vs. Digital Pixels

Digital printers work with CMYK—four tiny nozzles spraying microscopic dots to trick your eye into seeing a colour. Screen printing is the opposite. If I want a specific shade of neon pink or a deep, velvety navy, I have to mix that pigment by hand using a scale and a palette knife. I’m not layering dots; I’m pushing a physical layer of liquid ink through the mesh and onto the paper with a squeegee.

This creates a texture you just can't get any other way. You can actually feel the ink sitting on top of the paper. It has a "body" to it. Because the ink is opaque and thick, the colours stay vibrant for decades, whereas digital prints can sometimes look a bit flat or fade if they catch a bit of London sun.

The Multi-Layer Dance of Registration

The real technical headache—and the reason screen prints are valued as fine art—is registration. Each colour in my work requires its own separate screen, its own hand-mixed batch of ink, and its own pass across the paper. If I’m doing an eight-colour print, I have to line up that paper eight separate times with sub-millimetre precision.

If I’m out by a hair on the final layer, the whole thing is ruined. It’s a high-stakes game of patience. When you look closely at a screen print, you might see tiny, beautiful overlaps where two colours meet. That’s the evidence of a human being moving a squeegee, not a computer chip making a decision. That’s the soul of the craft.

So, when you're looking at a piece, remember it didn't just pop out of a machine at the click of a mouse. It’s the result of hours of mixing, pulling, washing, and drying. It’s a labor-intensive process that results in something tactile, durable, and genuinely unique. It’s not just a copy of an image; it’s a physical object made with a lot of sweat and a fair bit of trial and error.
