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.
