What color mat for *Color Bands* (Wadsworth Portfolio) — and why it matters

The mat’s role: balance, not competition

The Wadsworth Portfolio’s *Color Bands* (1971) relies on precise, saturated hues—typically four to six bands of flat color, each 5–10 cm (2–4 in) wide, in Sol LeWitt’s systematic style. The mat’s function is to contain these edges without introducing visual noise. Neutral mats (white, warm white, or pale gray) ensure the print’s chromatic weight dominates. Avoid colored mats: they risk clashing with the print’s non-hierarchical bands or, worse, implying a focal point where none exists.

For reference, the Fine Art Trade Guild defines a mat’s primary purpose as “protecting the art while directing the viewer’s eye inward.” In this case, inward means toward the print’s hard edges and the subtle optical vibrations between adjacent bands. A 100% cotton-rag mat (e.g., 250–310 gsm) resists acid degradation, which is critical for works on paper like LeWitt’s screenprints.

Proportions: the two-thirds rule in practice

A standard *Color Bands* print measures 50×70 cm (19.7×27.6 in). The mat’s top border should extend to ~12.5 cm (5 in), sides and bottom to ~7.5 cm (3 in). This adheres to the two-thirds rule (hanging the print so its center is ~145–150 cm / 57–60 in from the floor, with the mat’s top edge aligning roughly two-thirds up the wall above furniture).

For larger prints (e.g., 70×100 cm / 27.6×39.4 in), scale proportions accordingly: top mat at 15 cm (6 in), sides/bottom at 10 cm (4 in). These ratios prevent the print from appearing to float too high or sink into the frame. The American Institute for Conservation notes that asymmetrical mat widths (wider at top) “counteract the optical illusion of a descending composition.”

Glazing and UV protection: non-negotiable for color integrity

*Color Bands* employs pigment-based inks (likely screenprinted, per MoMA’s definition of LeWitt’s printmaking process), which are inherently light-sensitive. UV-protective glazing (e.g., 99% UV-blocking acrylic like Artglass AR or museum glass) is mandatory. Standard glass transmits ~50% UV; acrylic with a UV filter reduces this to 1–3%, per tests cited by the National Gallery of Art.

If displaying near windows, add a UV-filtering film to the glazing. The trade-off: acrylic is lighter and shatter-resistant but costs 30–50% more than glass ($200–$400 for a 50×70 cm frame vs. $120–$250 for glass). For high-humidity environments, opt for spaced glazing (a 3–5 mm gap between print and glazing) to prevent condensation.

Frame selection: thin profiles, neutral finishes

The frame’s role is structural, not decorative. For *Color Bands*, a thin-profile frame (1.5–2.5 cm / 0.6–1 in wide) in black, natural wood, or white maintains the print’s minimalist intent. Avoid ornate moldings or wide frames (>3 cm / 1.2 in), which introduce unnecessary weight. A framed Miro print, for comparison, often uses similar thin profiles to avoid competing with the art’s organic forms—whereas LeWitt’s systematic bands demand even greater restraint.

Metal frames (aluminum or brushed steel) offer durability but may reflect ambient light onto the print. Wood frames (e.g., ash or maple) should be sealed to prevent acid migration. Expect framing costs for a 50×70 cm print to range from $350–$600, depending on mat ply, glazing, and frame material.

Why this feels complicated (and how to simplify it)

The underlying concern—framing as an error-prone variable—stems from three factors: irreversible damage (e.g., acidic mats causing foxing), optical misalignment (e.g., mat proportions throwing off the print’s balance), and cost ambiguity (e.g., glazing upgrades adding 40% to the total). The solution is to isolate each decision:

• Mat: 100% cotton-rag, 4-ply, warm white (e.g., Bainbridge Alphamat or Crescent RagMat).
• Glazing: UV acrylic if budget allows; otherwise, UV-filtered glass.
• Frame: Thin, neutral, pre-finished (no custom staining or patinas).

For context, Hiroshi Nagai’s prints (often compared for their bold color fields) typically use even narrower mats—sometimes as little as 2.5 cm (1 in)—to emphasize the print’s edges. But LeWitt’s bands require slightly more breathing room to avoid a cramped effect.
