Level 2 — TronCalculator: Requirements

digitize print options & print price logic for online calculation; can also provide “print options only” (no pricing). Feeds accepted: CSV/XML/JSON (one structure per feed).

L2 feeds

Print Options Feed — what can be printed and where.
Print Prices Feed — how much it costs (logic & matrices).

“Print options only” is allowed (no pricing) and still enables locations/technologies in webshops.

L2 Print Options — required fields (per SKU or per Model+Color)

Field	Type	Constraints / Notes
PrintCode	string	Required, unique technique identifier (e.g., PAD, LASER, DTF).
ProductRef	string	Required, either ProductCode or tuple (ModelCode + Color). Must match L1.
PrintName	string	Required, human-readable (e.g., “Pad Print”, “Laser Engraving”). (“name of printing”)
LocationName	string	Required, e.g., “Barrel Left”, “Front Chest”. (“location of printing on the product”)
LocationCoordinates	string/json	Optional; designer-coordinates in px/mm (% allowed). Keep origin & orientation consistent.
MaxColors	integer	Required for color-based techniques.
MaxAreaW/H	number	Optional; printable area width/height with units.
PrintableSides	string	Optional; e.g., “Front”, “Back”, “Both”.
Notes	string	Optional; any constraints (e.g., curved surface).

L2 Print Prices — required fields (“full print price logic”)

Your logic must be explicitly computable from the feed—no hidden text rules. We support common pricing models below; choose one or combine as needed.

Field	Type	Constraints / Notes
ProductRef	string	Required (ProductCode or Model+Color).
PrintCode	string	Required, ties to Print Options.
Currency	ISO 4217	e.g., EUR, CZK.
QtyBreak	integer	Required tier (1, 50, 100, 250…)
BaseSetupFee	decimal	Per order or per position (see FeeScope)
FeeScope	enum	per_order, per_position, per_color
RunPricePerUnit	decimal	Base cost per unit at the QtyBreak before color/area surcharges.
ColorStepPrice	decimal	Optional, add per extra print color.
AreaTier	enum	Optional, e.g., {S,M,L} or area-range in cm².
AreaSurchargePerUnit	decimal	Optional per-unit surcharge by area tier.
PositionsAllowed	integer	Optional max printed positions included; extra position surcharge defined separately.
ExtraPositionSurcharge	decimal	Optional per additional position per unit.
MinCharge	decimal	Optional minimum order charge for the technique.
Notes	string	Optional technical notes (curved, special handling).

Validation rules

Every (ProductRef, PrintCode) present in Print Prices must exist in Print Options.
QtyBreak tiers must be strictly increasing per (ProductRef, PrintCode, Currency).
If MaxColors = 1, then ColorStepPrice must be 0 or omitted.
If AreaTier is present, AreaSurchargePerUnit must be provided.
Currency must match platform configuration (EUR by default unless specified).
“Print options only” delivery: you may skip the Price feed entirely.
