Dyeing, Printing, Color Management & Chemical Control
Evaluates a continuous washing range as the counter-current cascade it is: computes the wash ratio, the impurity left on the cloth after a given number of boxes at a stated stage efficiency, the same water spent as independent baths for comparison, the boxes a target actually needs and the least water the boxes already built could run on.

Models sublimation transfer as a saturating time-temperature dose, returning the efficiency a given press cycle achieves against the ceiling, the ink transferred and left on the paper, and what the residue costs per square metre.
Calculator
Dyeing, Printing, Color Management & Chemical Control
Combines spectrophotometer drift, repeatability and inter-instrument agreement in quadrature into an expanded uncertainty, subtracts it from the shade tolerance as a guard band, and reports which of the three terms is actually consuming the tolerance.
Calculator
Dyeing, Printing, Color Management & Chemical Control
Treats reactive wash-off as the geometric dilution series it is: computes the unfixed dye left after dyeing, the fixed fraction each rinse removes, the residual after a given number of baths, the baths actually needed to reach a target and the absurd single-bath liquor ratio that would match them.
Calculator
Dyeing, Printing, Color Management & Chemical Control
Derives screen open area and theoretical paste volume from mesh count and thread diameter, converts it into wet pick-up, dry deposit and dye applied per square metre, and gives the apparent viscosity a power-law paste has at squeegee shear rather than at rest.
Calculator
Dyeing, Printing, Color Management & Chemical Control
Models cyclic trimer released from polyester during high-temperature dyeing against what the cooling bath can still dissolve, returning the mass at risk of depositing on fabric and machine and the drop temperature above which nothing crystallises out.
Calculator
Dyeing, Printing, Color Management & Chemical Control
Separates metamerism from a plain shade mismatch by taking the colour difference under incandescent and fluorescent illuminants net of the residual difference under the reference, and reports the index, the margin against a limit and how many illuminants fail.
Calculator
Dyeing, Printing, Color Management & Chemical Control
Fits the Cegarra-Puente rate constant from a single measured exhaustion point, then returns half-dyeing time, the times to reach 95 and 99 percent of equilibrium, the exhaustion the programmed cycle will actually reach and the dye left in the bath when it stops.
Calculator
Dyeing, Printing, Color Management & Chemical Control
Compares a batch against the vessel it is loaded into, holding the machine to its minimum circulating volume, and returns the effective liquor ratio, the chemical overdose that part-loading forces, the salt wasted per batch and the smallest batch that still runs at the design ratio.
Calculator
Dyeing, Printing, Color Management & Chemical Control
Converts a linear or progressive dosing profile into the stock volume, the average and peak metering rates, the per-step addition schedule and the shortest dosing time the installed pump can actually hold, so the profile that is programmed is the profile that runs.
