Puff ink is a plastisol that has been modified with the addition of a heat reactive foaming agent. The ink expands when exposed to high temperature heat as the garment is cured. An additive to Plastisol inks which raises the print off the garment, creating a 3D feel. In this method when the paste is printed and dries it look like normal printing garments but once it is cured the prints gets raised from the surface of fabric.
Puff Printing Process
- Mesh Count: 80-305/inch (32T-122T cm) or according to ink specifications.
- Like this print we can make the Print screen at first.
- We make rubber color as normal.
- Mix an emboss or foaming color with the following color.
- Then print on the garments with following color mixer like as normal rubber print.
- Then we dry the print area by using heat. This is the turning point of this print. Because after getting the heat the print becomes puffed. Normally we dry the print area by dryer for small print. If the print area is larger then we heat press the area with curing machine.
- And, during a heat press please be careful regarding the color of the body fabric because the excessive heat can affect on the color of body fabric.
- Drying/Curing: While print is wet, heat the entire ink deposit to 275˚F/135˚C using a hot air gun or oven to puff. Do not overheat. For best results, allow ink to air cure 72 hours once puffed before washing.
Caution: Always test this product for wash-ability and durability prior to production.
Puff Printing Machine
- I advice all to use heat press machine instead of hand dryer machine, because it will make the puff evenly.
- And before heat press please adjust the temperature and pressure of curing machine to get the correct output. Less heat will give you a less puff print. And excess heat can damage your print area.
