Pasmore is probably the only British abstract painter whose name is known and whose work is valued all round the world.

And you can see why. It's the clarity and purity of these prints that strikes you as you enter the gallery.

He seems to get under the skin of things, to expose the fundamental rhythms behind the superficial façade.

It helps that he does it all with such a light touch. He has the relaxed control of a water diviner discovering something essential just below the surface of reality.

Full marks must also go to the printer who makes the difficult task of producing an impeccable print look easy. But you could say that of Pasmore too. It all looks so simple.

But if you leave the show thinking your four-year-old daughter could do it, you've probably missed the point. Peter McCarthy

Verdict: Clarity and purity
