Spot vs Process Cost Factor Lookup
Same job/currency actual spot vs process print quote contrast, exact safe minor units; no universal plate/run cost multiplier. Explicit declared color space/reference and caller applicability; not spectral equivalence, pigment mixing, press readiness or accessibility certification.
Description
Spot and process print quotes can be compared on one currency and job basis.
Spot and process print quotes can be compared on one currency and job basis.1
A cost ratio describes the supplied quotes rather than a universal spot-ink premium. Use Spot vs Process Cost Factor Lookup to evaluate the supplied inputs under the model explained below.
When to use Spot vs Process Cost Factor Lookup
Use Spot vs Process Cost Factor Lookup to evaluate the supplied inputs under the model explained below. Establish the units, measurement scope and model assumptions before entering values.
How to use Spot vs Process Cost Factor Lookup and understand its results
- Establish the units, measurement scope and model assumptions before entering values.
- Enter Caller spot quote minor, Caller process quote minor using the field table and validation rules below, then run the tool.
- Read Signed spot cost premium minor, Spot over process cost basis points; interpret the units, signs, ordering and unknown-value placeholders described below.
- Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerSpotQuoteMinor | Caller spot quote minor | number | Required; constraints below |
| callerProcessQuoteMinor | Caller process quote minor | number | Required; constraints below |
Enter nonnegative safe-integer spot and process quotes in the same currency's minor units; the process quote must be positive. Return spot minus process and spot/process×10000 rounded to the nearest integer with halves away from zero. The latter is a cost ratio in basis points, not the premium percentage: equal quotes return 10000, not zero. No rates or job specifications are supplied.
premiumMinor = spot−process; costRatioBps = roundHalfAwayFromZero(spot×10000/process) Use the field order, units and branch conditions described above.
| Output field | Meaning | Value type |
|---|---|---|
| signedSpotCostPremiumMinor | Signed spot cost premium minor | number |
| spotOverProcessCostBasisPoints | Spot over process cost basis points | number |

}Limitations and assumptions
A cost ratio describes the supplied quotes rather than a universal spot-ink premium. Apply the exact scope and assumptions explained above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
