thinner mix:

Pretreatment 1 kg + Distilled Water 2 kg ( 1:2 weight ratio)

rich mix:

Pretreatment 1 L + Distilled Water 1 L( 1:1 volume ratio)

When you dilute Pretreatment in rich condition, white is whiter but halo mark around the pretreated area may be seen easily and the washability may be worse. On the other hand, when you dilute in thinner mix, the halo mark may be improved but the print may be less white, and the of the diluted Pretreatment may not be stable.
