85% of visible color — not just 52%

Standard CMYK printing reproduces about half of what the human eye sees. Our Heidelberg XL75 8-color ECG (Extended Color Gamut) press adds orange, green, and violet ink stations — hitting colors in packaging that standard presses simply cannot match.

ECG — 8 colors (CMYK + OGV) 85%
Standard CMYK — 4 colors 52%
Brilliant oranges, grass greens, deep violets — in a single pass
No spot color plates needed — fewer setups, lower cost at scale
G7 certified color control — consistent run-to-run
Pairs with matte, soft-touch, gloss, and spot-UV finishes

Collector edition puzzle and game packaging with vivid ECG color
Wedge 01 — Artist & Collector Editions

When the box is part of the art

For puzzle makers, toy brands, and artist collaborations — the packaging has to carry the same visual weight as the product inside. ECG color does that. Standard CMYK doesn't.

"The deep blues and vivid oranges in our Holton Rower collaboration came out exactly as the artist intended — we had tried two other printers first."

— Puzzle brand customer, Brooklyn NY

Wedge 02 — Specialty Paper Goods

Puzzles, games, and tactile packaging that commands a premium

Beyond our ECG capability, we run conventional 7-color offset for high-detail CMYK work. Same factory, same QC, same US coordination.
