Matching the series to your product
The first step in evaluating VISPROX HSV7500 Pad Printing Ink is to identify the actual substrate. Do not decide by product name alone without knowing the plastic type, metal coating or textile structure. Prepare a sample with the production substrate and record any surface treatment.
Technical data notes
Material names, ratios and times in this section are preserved from the series technical records. Do not transfer an additive ratio to another series; read each ratio together with the adjacent product code and operating conditions.
| General Properties | Non-toxic pad printing inks comply with (EC) EN 71.3 and European Directive 2002/95/EC (RoHS). · HSV7500 Series Visprox Pad Printing Single- / Two-Component |
|---|---|
| Pad Printing Ink Applications | ABS · SAN · Akrilik · PET · Polycarbonate · Flexible PVC – Rigid PVC · Sentetik malzemeler · Wood · Yapay Rubber Hortumlar |
| Mechanical and Chemical Resistance | Esnektir. · Resistant to alcohols and some solvents. · Use with hardener to improve adhesion and chemical and physical resistance. · Lightfastness level DIN 6-8 provides resistance to fading caused by light. |
| Ink Preparation | For two-component use, add Hardener2 at 6-10% by weight. · Once mixed with hardener, the ink has a pot life of 8-10 hours. · Dilute and mix the ink with 20-30% No.51 or No.85 thinner. · In warm conditions, when printing fine details or halftone images (e.g. 80-120 lines per cm), use some No.4 Retarder. |
| Drying and Curing Properties | Dries in 5-10 minutes at an ambient temperature of 20°C. · For drying within seconds, use hot-air circulation ovens (60-80°C) positioned over a rotary table or conveyor, or high-output spot heat sources (air or infrared). · The ink is ready for testing after 1-2 days as a single-component system, or 5-6 days as a two-component system. |
| Colour Range | HSV7500 series standard colour options. · 12 Colormatic colour options. · The Visprox colour range includes 12 Colormatic colours. All colours can be intermixed. |
| Auxiliary Supplies and Additives | No7 Retarder. · No4 Retarder. · No8 Retarder. · No27 Retarder. · No51 Thinner. · No85 Thinner. · VVD-2 Fast Pad Printing Thinner. · Matting Agent Pasta. |
Three separate decisions in sample preparation
| Substrate | Verify the material and any coating; do not select a series by product name alone. |
|---|---|
| Preparation | Match hardener, thinner and other additive codes to the series. Record the quantities used in the mixture. |
| Inspection timing | Plan initial appearance inspection separately from application durability testing. Drying and curing are different processes. |
Evaluate colour and durability separately
A sample close to the colour reference does not automatically meet application durability requirements. Record colour appearance, artwork clarity and required performance under use conditions as separate inspection headings. Label every sample with material details when testing the same series on different substrates.
Preparing for a technical discussion
- VISPROX HSV7500 Pad Printing Ink product name and colour to be used
- Substrate raw material and coating information
- Pretreatment applied and production environment
- Required visual result and conditions the print will encounter in use
