Zahn Cup Supplier in Indore
Print Pro Tech is a trusted Zahn Cup manufacturer in Indore, supplying reliable viscosity measurement tools for the printing, flexible packaging, coating, and converting industries across the country. Our Zahn viscosity cups are used by press operators, ink technicians, and quality managers to measure and control ink viscosity, coating viscosity, and varnish flow properties during production. The company also operates as a dependable Zahn Cup supplier in Indore, delivering accurate and durable flow cup viscometers for production floors and quality control laboratories.
The Zahn Cup functions as an easy-to-use viscosity measurement device which determines the flow time for various liquids, including printing inks and coatings and varnishes and adhesives and solvents. The control of ink viscosity measurement enables operators to maintain proper ink film weight and print density and color consistency and ink transfer performance for their flexo and gravure and coating work.

The printing process for flexo and gravure needs consistent control of ink viscosity because it helps maintain proper ink density and color accuracy and prevents dot gain and print defects. The Print Pro Tech team can help you select the correct Zahn Cup number for your ink type, solvent system, and application. As an experienced Zahn Cup supplier in Indore, we supply accurate viscosity flow cups for reliable ink viscosity measurement at every stage of production.
How Does a Zahn Cup Work?
The Zahn Cup operates according to the principles of efflux viscometry. The cup consists of a small metal cup which has an exact measurement of its bottom opening.The procedure requires the operator to completely immerse the cup into the liquid before lifting it out to begin the timing process.
The reading is compared against the target viscosity range specified for the ink or coating being used. The ink requires solvent addition or thinning when its flow time exceeds the maximum allowed limit. The ink produces print quality problems when its flow time becomes lower than the minimum required level because it creates ink misting and reduced color density and bad ink film formation.
Zahn Cups exist in five standard numbered versions, which range from Zahn Cup No. 1 to No. 5, and each version has a distinct orifice diameter that matches a particular viscosity measurement range.
Zahn Cup No. 1 — for very low viscosity liquids
Zahn Cup No. 2 — for low to medium-viscosity inks and coatings
Zahn Cup No. 3 — for medium viscosity flexo and gravure inks
Zahn Cup No. 4 — for higher viscosity inks and coatings
Zahn Cup No. 5 — for high-viscosity liquids and adhesives
Key Features of the Print Pro Tech Zahn Cup
- Accurate efflux viscometry for printing inks, coatings, varnishes, and adhesives.
- Available in Zahn Cup No. 1 to No. 5 to cover a wide viscosity range.
- Simple and fast viscosity measurement method suitable for production floor use.
- The material choice of stainless steel provides chemical resistance and enduring strength to the structure.
- The flow time measurement system uses a specially designed orifice which provides accurate flow rates that can be measured at any time.
- The press-side operational area requires a compact and easy-to-carry device which measures viscosity.
- The system ensures that ink viscosity stays constant while providing color density control, which results in high-quality printed output.
- Flexo printing and gravure printing and coating and lamination industries make frequent use of this technology.
- The system prevents ink wastage while it reduces printing errors and minimizes press downtime, which occurs because of changes in viscosity.
