I've been pulling screenprints for twenty-six years. Paper weight is the decision that shapes everything else.
Most people focus on the image. They should look at the paper first.
What GSM Actually Means
GSM stands for grams per square metre. It's the weight of the paper.
A standard office sheet runs about 80gsm. Flimsy. Translucent. Useless for screenprinting.
I work between 280gsm and 350gsm. That's the range where ink sits properly on the surface without soaking through.
Below 250gsm, you'll see bleed-through on darker layers. The paper buckles during drying. By the time you've pulled fifty prints, half the edition looks warped.
Above 400gsm, you're into board territory. The paper fights the squeegee. Registration shifts between layers because the stock won't lie flat under the screen.
Somerset Satin 300gsm is my standard. Always has been.
How Weight Affects Ink Saturation
Heavier paper holds more sizing. That's the coating that keeps ink on the surface instead of sinking into the fibres.
When I print a solid black layer on 300gsm Somerset, the ink sits wet and dense. It doesn't wick. It doesn't fade into the tooth of the paper.
On lighter stock, the same ink looks thin. Patchy. You can see through it if you hold the print to the light.
I learned this the hard way in 1999. Bought a batch of 220gsm stock because it was cheaper. Printed an entire edition of twelve-layer architectural prints. Every single one showed ghosting from the base layers bleeding through the lighter tones on top.
Binned the lot. Never went below 280gsm again.
Texture Changes With Weight
Thicker paper has more surface texture. That's not always good.
Hot-pressed papers like Somerset Satin smooth out as weight increases. At 300gsm, you get a slight tooth that grabs the ink without showing individual fibres.
Rough papers like Fabriano Rosaspina amplify texture at higher weights. At 285gsm, it's already too toothy for fine halftones. Great for bold graphics. Terrible for detail.
I choose paper weight based on the finest line in the design. If I've got hairline type or delicate crosshatching, I want a smooth heavyweight. If it's solid shapes and hard edges, I can tolerate more tooth.
The weight dictates how much texture comes through. You can't separate the two.
Why I Use Somerset 300gsm
It's acid-free. Buffered. Archival-rated for two hundred years if you store it properly.
The cotton content is twenty-five percent. That gives it enough body to stay flat without going rigid. It feeds through my vacuum bed cleanly. No ripples. No drag.
At 300gsm, it holds up to twelve layers of water-based ink without cockling. I've tested it. By layer seven, lighter stocks start to wave at the edges. Somerset stays dead flat.
It also feels right when you pick it up. There's a substance to it. Collectors notice that. They know they're holding something built to last.
What Collectors Should Check
If you're buying a screenprint, flip it over. Look at the back.
You should see zero ink bleed-through. None. If there's even a faint shadow of the image showing on the reverse, the paper was too light or the ink was wrong.
Check the surface. Run your finger across the printed areas. Heavyweight paper lets the ink build up physically. You'll feel the layers as a very slight relief. That's proper ink deposit. On thin stock, everything sits flat because it's sunk into the fibres.
Ask the weight. Most printmakers will list it. If they don't, that's a red flag. Anyone serious about longevity knows their gsm.
Look for acid-free stock. Somerset, Fabriano, Arches, BFK Rives. Those are the standards. If it's on copy paper or poster stock, walk away.
When Weight Doesn't Matter
Gig posters. Street prints. Things designed to live on a wall for five years and yellow gracefully.
For those, 200gsm is fine. The aesthetic is rough. Bleed-through adds character. The edges curl over time and that's part of the look.
I don't print that way. My work is built to outlive me. That means proper stock from day one.
The Feel of Heavyweight Paper
There's a confidence to pulling a print on 300gsm Somerset. The paper doesn't shift. It doesn't fight you.
When the squeegee pushes ink across the surface, you feel the stock absorbing the pressure without flexing. That's how you know the registration will hold across all layers.
Light paper chatters under the blade. You lose pressure at the edges. Heavyweight stock sits solid. Every pass is identical.
That consistency is why edition prints match. It's not just skill. It's the physics of the paper.
