Ink & Adhesive Consumption
Physically correct mass: dry kg = area × coverage × dry GSM ÷ 1000, aur wet kg = dry ÷ solids. Excel wala GSM × ₹/kg shortcut default nahi hai.
Print / lamination area
Web jo machine se guzarta hai: width × running metres.
Area
4,884 m²
Pouch Cost job se liya: slit 580 mm × 8,421 m (waste ke saath). Badalna ho to upar likho.
Ink — colour by colour
Dry kg = area × coverage % × dry GSM ÷ 1000, har colour ke liye.
Starting value — apni ink ki TDS / viscosity setting se lo.
Starting bands (GSMCalculator): gravure shallow 1.0–1.2, standard 1.2–1.8, heavy 1.8–2.5 GSM per colour; flexo 0.8–1.5. Coverage: text 20–35%, mixed 40–60%, heavy 60–80%, solid 90–100%. Yeh starting range hai — measured dry GSM better hai.
Adhesive
Dry kg = area × bonds × dry GSM ÷ 1000. Solvent-based: wet = dry ÷ solids. Solventless: wet = dry.
2-layer 1, 3-layer 2, 4-layer 3.
Solventless = 100.
Dry 2.0–2.8 GSM per bond on film/foil (Cytech HILAM GP-50 guide; 3.0–3.5 on paper). 2.5 is GSMCalculator's 2-ply default. Solids % is a starting value — read it off your adhesive TDS. Dry 1.2–2.8 GSM per bond (Toplusse: light 1.2–1.8, medium 1.8–2.2, retort 2.2–2.8). 100% solids, so wet = dry.
Rate basis
Dry: rate solids ka hai (structure builder yahi use karta hai). Wet: rate usi mixed ink / adhesive ka hai jo press par chal raha hai, upar diye solids % par. Rate book mein ek hi number hota hai — basis badalne par number khud convert nahi hota.

Sirf dry kg laminate mein rehta hai. Wet kg drum se nikalta hai — purchase aur stock ke liye wahi dekho.
