InJoy Puzzle Company × Holton Rower
Two printers had already tried and failed to reproduce a Holton Rower hand pour painting on a limited-edition puzzle. This is how Sinso solved it.
The brief
InJoy Puzzle Company (Brooklyn, NY) wanted to release a limited-edition puzzle in collaboration with artist Holton Rower. The puzzle print needed to reproduce a Rower hand pour painting at gallery fidelity: deep blues, saturated oranges, and continuous color gradients across the entire puzzle surface.
Why CMYK failed
Two earlier printers had attempted the job in conventional CMYK. The deep blues flattened to navy. The vivid oranges shifted toward muddy red. The gradient transitions banded visibly. CMYK cannot reach those points in the visible gamut. No amount of profile tuning closes that gap.
What Sinso did
Sinso printed the puzzle. The artwork was processed for 7-color ECG separation on the Heidelberg Speedmaster XL 75, using a press-specific ICC profile built for the substrate. A G7-calibrated digital proof was reviewed by InJoy before plates were made. The final press run was measured inline against the approved proof. Die cutting was handled at a separate Ningbo factory.
The result
InJoy's own words: "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."
