SOLVENT-BASED GRAVURE PRINTING INKS · APPLICATION REVIEW
Review viscosity drift and pigment dispersion from the ink system—not a preselected grade.
If viscosity drift or pigment-dispersion instability is under review, begin with the resin and solvent system, test conditions and required print result. EC can enter candidate review; the commercial grade and solvent compatibility require evidence review and customer sample evaluation.

Request a Candidate Review →BUILD THE APPLICATION BRIEF
Describe what happens in your process.
Start with the finished product, the stage where the issue appears and the result you need. You do not need to know the chemistry to begin.
Which ink, resin and solvent system is under review?
Define the actual ink system before discussing an EC commercial grade.
- Finished product or dosage form: Solvent-based gravure printing inks
- Process sequence and conditions: Resin, solvent, pigment dispersion and printing
- Product names entering initial review: EC
- State the destination market, trial quantity and expected commercial volume.
What observable stability problem needs to change?
Describe the viscosity drift or pigment-dispersion issue in the current process.
- Observed problem: When does viscosity or dispersion become unstable?
- Identify the current material, formulation and supplier grade when available.
- State the target result in measurable or observable terms.
- Record when the issue first appears and how it is checked.
Which test conditions and print result define acceptance?
Record the viscosity method, temperature, fixed process conditions and required print result.
- Use the current formulation as the control and change one candidate variable at a time.
- Possible comparison points: viscosity at a stated concentration and temperature, dispersion stability, print transfer, adhesion and drying
- Hold raw materials, addition order, equipment settings and test timing constant.
- Agree the method, unit, time point and pass/fail limit before testing.
What completes the technical and buying review?
Add the current reference, intended use, destination market and required document categories.
- Product name: applicable TDS and SDS / MSDS.
- Commercial grade: current specification and stated test methods.
- Sample or production batch: COA tied to the identified reference.
- Use and market: certificate and regulatory scope reviewed separately.
CANDIDATE PRODUCT-NAME DIRECTIONS
Review a candidate against your actual process.
A product name does not establish the exact grade, dosage or suitability. Compare the intended function, specification and test conditions before choosing a sample.
EC
A product-name direction for solvent-based gravure ink review. Commercial-grade and solvent-compatibility decisions require evidence and customer testing.
- Function to evaluate
- Viscosity and pigment-dispersion review
- Candidate screening basis
- EC is a product-name candidate for evaluation against the stated Viscosity and pigment-dispersion review conditions. This is a reason to compare, not a grade recommendation or performance conclusion.
- Conditions still to validate
- Settling or separation. When does viscosity or dispersion become unstable? Possible comparison points: viscosity at a stated concentration and temperature, dispersion stability, print transfer, adhesion and drying. Hold raw materials, addition order, equipment settings and test timing constant. Agree the method, unit, time point and pass/fail limit before testing.
- Evidence status
- GENERAL APPLICATION REFERENCE ONLY · JNP APPLICATION EVIDENCE NOT PUBLISHED
General application context only. This reference is not a JNP trial, customer case, grade recommendation, dosage or performance result.
EVIDENCE STATUS
Know what is established—and what still needs proof.
Each layer supports a different decision. Moving forward does not turn an application indication into a final suitability claim.
Use the application guide to frame the requirement
The public page helps describe the finished product, process, observed problem and target result. It is guidance, not a tested JNP formulation.
Review the application guide →Treat the product direction as a candidate
A product name or commercial grade shown here is a starting point for comparison. It is not a final recommendation or interchangeability claim.
Review candidate directions →Check documents against the specific request
TDS, SDS / MSDS, grade specifications, batch CoA and market documents support different decisions. Availability and release permission are checked separately.
Request a Candidate Review →Confirm suitability in the customer’s system
Compare an identified sample with the current baseline under recorded conditions and agreed acceptance criteria before making a production decision.
Request a Candidate Review →Confirm the commercial conditions for each order
Quantity, packaging, sample charge, timing, business-day calendar, trade terms and document scope are confirmed in the applicable written quotation or order confirmation.
Request a Candidate Review →DOCUMENTS AT THEIR TRUE LEVEL
What can each document support?
Match the product, grade, batch, certificate and market records to the question you need answered. Availability and permission to share are checked separately.
Product-level information for the named chemistry. It does not define every commercial-grade parameter.
Defines the named candidate and the controlled comparison points used in the review.
Records results for the stated grade and batch, not the complete product family.
Checks the holder, site, covered product or brand and validity without extending the certificate beyond its wording.
Connects the named product and intended use to the destination market as a separate review from technical sheets and certificates.
FROM QUESTION TO PURCHASE
One path keeps the technical and buying decisions aligned.
A candidate recommendation begins the evaluation; customer testing and commercial review complete the decision.
Define the actual requirement
Record the finished product, process, current issue, target result and destination market.
Narrow a testable candidate
Connect the brief to a product-name direction and, when supported, a commercial grade.
Confirm the evidence level
Match each product, grade, batch, certificate and market document to the decision it can support.
Test and align supply
Use customer testing before confirming specification, quantity, packaging, timing and commercial terms.
SCREENING ONLY
Viscosity and pigment-dispersion review
Use these application guides to describe your product and process. They do not provide a tested JNP formulation or confirm grade suitability. Product names are starting points for discussion; agree the candidate and trial conditions before testing. Record the current formulation, process settings and comparison sample. Agree the test method and acceptance criteria before comparing candidates. No JNP application trial result is published on this page yet.
