From incoming materials to delivery, connected with application feedback.

IQC

Incoming-material inspection

Check raw-material names, batches and formulation uses; evaluate appearance, viscosity, pH, conductivity or color response according to material requirements.

IPQC

In-process inspection

Sample through the process, monitoring pigment dispersion, particle size, filtration and physical-property changes.

FQC

Finished-product inspection

Evaluate liquid properties alongside printing performance, adding heat-aging, settling, rubbing, washing or transfer tests where appropriate.

OQC

Outgoing inspection

Check model, color, batch, packaging, sealing and delivery documents, linking to the corresponding finished-product inspection.

Customer feedback

Application feedback

Collect equipment, printhead, substrate, environment and problem-proof details, bringing customer usage conditions into technical evaluation.

Corrective improvement

Corrective improvement

Distinguish material, dispersion, filtration, storage and application factors; after corrective measures, retest under the same conditions.

Specific items, methods and acceptance conditions depend on the corresponding ink series.

Instruments and evaluation directions

Different indicators answer different questions. Record samples, methods and conditions, then interpret results with actual equipment and materials.

Viscosity
Testing equipment

Viscosity

Evaluate ink flow resistance and ink-supply compatibility. Record temperature, measurement method and reading, then interpret them against the printhead and ink-supply system requirements.

pH
Testing equipment

pH

Measure the ink's acid-alkaline state and evaluate formulation stability for the product system and measurement conditions.

Conductivity
Testing equipment

Conductivity

Use conductivity measurement to observe ionic response and batch differences and record the test temperature.

Particle size and dispersion
Testing equipment

Particle size and dispersion

Measure pigment-particle distribution and changes before and after aging, focusing on dispersion, agglomeration and coarse-particle control.

Surface tension
Testing equipment

Surface tension

Evaluate wetting and droplet behavior. Distinguish static and dynamic measurements, state the temperature and method, and combine them with actual jetting and substrate tests.

UV–Vis spectrum
Testing equipment

UV–Vis spectrum

Use it to compare spectral absorption and colorant response; state the dilution, path length and reference conditions. Evaluate liquid absorption spectra separately from printed color density.

Color and optical density
Testing equipment

Color and optical density

Compare L*a*b*, color difference and color density on the specified media while keeping the illuminant, measurement geometry and printing conditions consistent.

Filtration and ink supply
Testing equipment

Filtration and ink supply

Select the filtration method for the product system and assess insoluble-particle control, ink-supply status and jetting performance.

Rubbing and adhesion
Testing equipment

Rubbing and adhesion

Use the actual substrate and curing conditions, state the dry/wet state, load and number of cycles, and compare staining or surface damage.

Print clarity and bleeding
Testing equipment

Print clarity and bleeding

Use color blocks, fine lines and adjacent colors to observe boundaries, uniformity and bleeding; state the print mode and media.

Durability and application verification
Testing equipment

Durability and application verification

Evaluate washing, water resistance or other durability for the intended use. State the sample and process; results apply only to the listed conditions.

Storage and stability
Testing equipment

Storage and stability

Use storage observations and heat-aging tests to compare settling, separation and physical-property changes in support of product-stability evaluation.

Common selection and technical questions

How do I narrow down dye, pigment and sublimation options?

Describe the end use and substrate first, then check equipment, color channels and process. Dyes and pigments serve different equipment/media combinations; polyester transfer and direct disperse printing have corresponding sublimation series. Color alone does not establish interchangeability.

What should I prepare if colors change after switching paper or ink?

Keep original settings, old proofs and new proofs, recording paper, equipment, print mode and current color management. Discuss ICC or setting changes for the specific ink and media.

How should I report DTF white-ink opacity, dewetting or oily-residue issues?

Provide color/white ink models, PET film, hot-melt powder, print mode, curing and heat-press conditions, and retain problem proofs. Verify the combination rather than drawing conclusions about every cause from one ink or one image.

How should DTG opacity and wash performance be evaluated?

Describe fabric composition/base color, pretreatment, printing and curing conditions. Evaluate color, feel, adhesion and washing on actual garment samples; confirm parameters for the corresponding model and material.

Where should I start with color differences or ghosting in sublimation?

Record transfer paper, fabric, print configuration and heat-fixation conditions, retaining both printed paper and transferred fabric. Review materials, equipment and transfer steps individually; do not copy temperatures and times from other products.

Can one maintenance procedure cover ink changes, shutdowns and cleaning?

First check the current ink system, printhead, ink path and seals. Confirm compatibility and purpose separately for cleaning and protection products; unconfirmed mixtures, soaking methods or fixed intervals must not become universal procedures.

Which documents govern storage and shipping conditions?

Request current product and safety information for the specific model and check packaging, batch and supply requirements. If separation, settling or abnormal conditions appear, record them and contact the technical team rather than deciding usability by appearance alone.

How should I request TDS, SDS and COA during an inquiry?

Specify product code, color, use, project requirements and document type. Technical, safety and batch-quality documents serve different purposes. Check model, version, scope and batch after receipt; a document title does not replace applicability verification.

From applications to samples

Move ink selection forward to practical trial printing.

Provide equipment, materials, color configuration and target results to confirm suitable models and sample arrangements.
