The global digital textile printing ink market hit $2.37 billion in 2026 and is growing at 19.5% CAGR. DTG production volumes are climbing. Print-on-demand is eating batch production. Yet across thousands of print shops, there is one bottleneck almost nobody talks about.
It is not the printer. It is not the ink.
It is the pre-treatment dryer.
For years, every DTG shop followed the same workflow: spray pre-treatment solution onto the garment, run it through a dryer, wait for it to cool, then load it onto the printer — and hope the operator did not apply too much, too little, or in the wrong spots. If the fabric came out stiff, that was just the cost of doing DTG.
INKBANK asked a different question: what if pre-treatment were a print function instead of a spray function?
The answer is wet-on-wet DTG.
The garment endures two separate high-temperature cycles — first pre-treatment curing, then print fixation. Each cycle degrades the fiber structure. By the time the finished shirt reaches the buyer, the fabric has lost the softness that made it worth printing on in the first place. Premium brands reject these garments not for print quality, but for hand feel.
Manual spray application is an operator-dependent variable. One operator sprays heavier. Another goes lighter. The same operator sprays differently at 8 AM and 4 PM. The result: batch-to-batch color variation that no amount of post-processing can correct. Pre-treatment coverage directly controls color saturation. Inconsistent coverage equals inconsistent output.
Standalone pre-treatment drying is not a step — it is a queue. Every garment spends 2–4 minutes in a dryer, then cools for another minute before it can be loaded. Multiply by 500 units a day. The printer is idle while the dryer runs. The dryer is the constraint, not the printhead.
Spray equipment occupies floor space that could hold another printer. Dryers consume electricity at industrial rates. Pre-treatment mist drifts into the shop air, creating respiratory hazards that trigger occupational health compliance — protective equipment, air quality monitoring, ventilation upgrades. These are not line items on the ink invoice. They are line items on the P&L that nobody attributes to pre-treatment.
INKBANK's wet-on-wet DTG ink replaces spray application with Drop-on-Demand (DoD) inkjet deposition. Pre-treatment fluid is formulated as a jettable liquid, dispensed through a dedicated printhead channel — with the same precision as CMYK ink.
The three layers — pre-treatment, white ink, CMYK — print synchronously in a single pass on one machine. No intermediate drying. No spray booth. No operator judgment call on coverage.
This is not a process improvement. It is a process removal.
| Step | Traditional DTG | INKBANK Wet-on-Wet |
|---|---|---|
| Pre-treatment | Manual spray gun | Printhead jetting |
| Intermediate drying | Required (dryer + cooling) | Eliminated |
| White + CMYK | After pre-treatment cures | Synchronous with pre-treatment |
| Heat cycles | 2 (pre-cure + fixation) | 1 (fixation only) |
| Operator variables | Coverage, pressure, dry time | Zero — digital control |
Inkjet deposition meters exactly what the fabric needs — no overspray, no runoff, no pooling. Traditional spray overshoots the garment edges and saturates areas that do not need coverage. Less fluid purchased per unit. Less waste handling at discharge.
Remove the pre-treatment dryer from the workflow and the math is straightforward: a step that took 3–5 minutes per garment is now zero. The printer prints. That is it. A shop running 500 units per day recovers 25–40 production hours per week. Same machines. Same operators. Twice the output.
Every high-temperature cycle takes something from the fabric. Eliminating the pre-cure means the garment arrives at the fixation stage with less cumulative thermal stress. The printed shirt feels like an unprinted shirt. For brands selling premium blank garments ($8–12 wholesale), the hand feel of the printed product must match the raw garment. One bake instead of two makes that achievable.
Not ink cost. Not pre-treatment fluid savings alone. Total operational cost — equipment depreciation, electricity, floor space, labor hours, consumables, waste handling, rework from quality inconsistency. When you remove a process step, you remove all of its associated costs simultaneously. The savings compound.

Three market shifts are converging on DTG production:
●Brands are tightening hand-feel specs. Premium blank manufacturers sell $8–12 wholesale garments. Their buyers inspect printed samples for softness before approving production. Traditional two-bake DTG is increasingly rejected at this checkpoint.
●On-demand is eating batch production. E-commerce fulfillment, event merchandising, and personalized apparel demand same-day turnaround. A 3-minute drying bottleneck cannot compete with single-pass.
●Occupational health regulation is tightening. Ventilation requirements, VOC monitoring, and worker exposure limits increase year over year. Removing spray removes compliance exposure.
The DTG market is not waiting for a better spray gun. It is waiting for the spray gun to become unnecessary.
You should not need a spray booth and a drying tunnel between your pre-treatment and your printer. One pass. One bake. Soft fabric. Done.
