Note:
The amount and type of Neoviprint Binder as well as Neoviprint auxiliaries to be used is very much a question of the type of fabric printed, the fastness required and the final handle wanted.

Recipes therefore should be adapted to the particular circumstances.

In some very deep colours , to achieve extra fastness, Neoviprint binder can be added more than 30% and handle is not affected.

Neoviprint binder should be used in a ratio 6 part to 1 part pigment with a minimum level of 8% in the print paste.

Neoviprint Binders can be used together with other commercial binder, thickener and other auxiliaries.

Curing
After printing, adequate curing is necessary
First step:
Dry at under 130, fastness could be affected for immature fixing if temperature is too high at this stage.
Second step:
To achieve proper fastness results, hot air fixation is essential
3 min. at 150 with hot air
Or 4 min at 140 with hot air
Or 2 min at 160 with hot air
Or 1 min at 170 with hot air

At lower temperature , curing times are longer. For example if curing at 100C, hot air could be more than 10 minutes but much depends on fabrics printed.

Some pigment colours change shade at high temperature, tests must be performed before production run especially for light shades.

Pure synthetic fabric or its blend may need higher temperature to cure.

Neoviprint binder in some cases can be steamed for fixation, for example: some pigment printing lines pattern together with reactive printing pattern.
