DIGIPRINT-458 | Pretreatment auxiliary for digital printing of Cellulose and Viscose

Digiprint-458 is a medium viscosity thickening agent which is applied in the pre-treatment padding process before Ink-Jet printing specially for cotton and viscose fabrics. Digiprint-458 is also suitable for all types of fabrics printed with disperse and reactive. Digiprint-458 locally increases the viscosity thereby prevents spreading of prints. Digiprint-458 delivers level prints with sharp outlines and improved colour value. It has a film forming and adhesion property. The advantage of Digiprint-458 is ready to use product with consistent viscosity. Digiprint-458 is stable as there is no bacterial attack. The feel of the fabric is not affected. It has easy wash-off properties.

Note :

• Digiprint-458 can be applied by coating with 50% diluted product.
• Concentration of Digiprint-458 to be added depending on GSM of fabric. For higher GSM fabric, lesser quantity of Digiprint-458 is required compared to lower GSM fabric.

Storage : Store in cool, ventilated shed away from heat and direct sunlight. Storage temperature should not exceed 35 deg C. Close lids firmly to avoid contact with air and moisture.

Shelf Life : 9 months from the date of manufacturing, if stored under controlled conditions.
