Rotary or Digital: Where the Two Cost Lines Actually Cross
Routes a print book design by design instead of by a rule of thumb. Rotary is almost all fixed cost — a screen per colour per colourway, strike-offs, setup.

Printing/Dyeing
Coloration science from color matching to fixation kinetics. Covers dyes, pigments, printing methods, shade reproducibility, and fastness testing. This section explains practical decision criteria, typical test methods, and failure modes that matter in real production. Readers get checklists, calculation steps, and case examples connecting specifications to cost, reliability, and compliance. Links map core concepts to upstream inputs and downstream processes so choices remain consistent across sourcing, manufacturing, and end-use performance. Each article includes definitions, diagrams where helpful, and plain-language notes to help newcomers ramp quickly while giving experienced professionals the depth needed to troubleshoot and optimize. Standards references are cited with context, and whenever trade-offs exist, we make them explicit so you can defend decisions.
