Sheen, shading and shimmer:
reading an ink before you buy

Shading is an ink's natural variation between light and dark within a single stroke — thin spots read pale, pools read saturated. High-shading inks like many Diamine shades make even neat handwriting look dimensional. Low-shading inks (think classic blues) write flat and uniform.

Wetter pens and broader nibs show more shading. A dry fine nib flattens almost everything, which is why nib choice and ink choice are the same decision.

Sheen is a surface reflection in a contrasting colour — a blue ink that flashes red at certain angles. It appears where ink pools heavily, which means wet writers and saturated colours show it most.

Fair warning: heavy sheen inks are maintenance ink. The dyes that create the effect clog feeds faster, so pens running sheen monsters get flushed more often — see the cleaning piece.

Shimmer inks carry actual particles — mica or similar — suspended in the liquid. Stunning on the page, and the number one cause of 'my pen won't write' at our repair bench. The particles settle in feeds and don't come out with enthusiasm.

Rules if you insist (and everyone insists eventually): dip rather than fill, use a pen you don't love too much, flush weekly, and never let a shimmer pen dry loaded.

Every ink we sell or recommend gets swatched on the same 160gsm paper with the same medium nib — that consistency is what makes swatches comparable. Then a week of daily writing to catch slow-feed problems that a swatch can't show.

Building your first ink shelf? Three reliable starters: a well-behaved blue-black, one high-shading colour, and something you personally just love looking at. Skip the 30ml rainbow — samples first.
