THE CHALLENGE → THE FIX

Inefficient Paper Roll Usage.

Without automated job splicing capabilities, Darwill was printing one job per roll, leading to substantial paper waste and increased production costs.

An intelligent paper roll optimization and job splicing system — integrated directly into the existing workflow, with clear instructions for the team that runs it.

darwill-production.diff
One job per roll leaving significant unused paper
No automated way to combine multiple jobs efficiently
Difficulty identifying where one job ends and another begins
Manual calculations prone to errors and inefficiency
+ smart job splicing
+ roll calculation engine
+ separator template generation
+ production workflow integration
