Sublimation Printing vs DTG (Direct-to-Garment).

Sublimation and DTG are the two dominant digital printing technologies transforming India's ₹5,000+ crore custom printing market. They enable print-on-demand fashion — zero inventory, infinite designs.

Sublimation printing uses heat to turn ink into gas that bonds with polyester fibers. The result is vibrant, all-over prints that are part of the fabric (not sitting on top). It is the standard for sportswear, activewear, and all-over print fashion.

DTG (Direct-to-Garment) printing works like an inkjet printer — spraying water-based ink directly onto cotton and cotton-blend fabrics. It excels at detailed, photo-quality prints on dark and light garments. DTG powers the global custom T-shirt industry.

Sublimation: The All-Over Print

Key Properties:

• Fabric Requirement: Polyester only (or poly-coated)
• Process: Ink → heat press (200°C) → gas → bonds with fiber
• Print Area: Full garment coverage (all-over printing)
• Feel: No texture — ink becomes part of the fabric
• Wash Durability: Excellent — never cracks, peels, or fades
• Colour Range: Vibrant, unlimited colours

Types:

• Cut & Sew Sublimation — Print on fabric, then cut and sew
• Transfer Sublimation — Print on paper, transfer to garment
• All-Over Sublimation — Entire garment, seam-to-seam

Best Use Cases:

• Custom sportswear and jerseys
• Activewear and athleisure
• All-over print T-shirts and dresses
• Flags, cushion covers, mugs
• Phone cases and accessories

Pricing (India Market):

• Sublimation per piece: ₹80–200 (printing cost)
• Sublimation printer: ₹50,000–5,00,000
• Polyester blank T-shirt: ₹80–150
• Full setup cost: ₹1–3 lakh (entry level)

DTG: The Cotton Printer

Key Properties:

• Fabric Requirement: Cotton and cotton-blend (best on 100% cotton)
• Process: Inkjet sprays water-based ink directly on garment
• Print Area: Limited to printable area (typically chest/back)
• Feel: Slight texture on dark garments (white base layer)
• Wash Durability: Good — 50+ washes with proper pre-treatment
• Colour Range: Full CMYK, photo-realistic

Types:

• Standard DTG — Print on white/light garments
• White Ink DTG — Print on dark garments (white base layer first)
• DTF (Direct-to-Film) — Newer hybrid, works on any fabric

Best Use Cases:

• Custom cotton T-shirts
• Merchandise and band tees
• Personalized gifts
• Small-batch fashion prints
• Prototype and sample printing

Pricing (India Market):

• DTG per piece: ₹100–350 (printing cost)
• DTG printer: ₹3–15 lakh
• Cotton blank T-shirt: ₹100–250
• Full setup cost: ₹4–8 lakh (entry level)

Choose sublimation for sportswear, activewear, all-over print fashion, and merchandise where polyester is acceptable. Sublimation is cheaper per print, faster, and produces more vibrant results.

Choose DTG for cotton T-shirts, premium merchandise, and any product where cotton comfort is non-negotiable. DTG is the industry standard for custom T-shirt businesses.

For print-on-demand business: Many Indian entrepreneurs use both — sublimation for activewear/all-over prints and DTG for cotton tees. Platforms like Printrove, Blinkstore, and Qikink handle fulfillment for both technologies.

Starting a print-on-demand business in India:

Option 1: Use a POD platform (₹0 investment): List designs on Printrove, Blinkstore, or Qikink — they print, pack, and ship. You earn ₹100–300 per sale. Great for testing designs with zero risk.

Option 2: Own equipment (₹2–8 lakh): Buy a sublimation setup (₹1–2 lakh) for polyester products or DTG printer (₹4–8 lakh) for cotton. At 20+ orders/day, you break even in 6–12 months.

Market insight: Custom printed T-shirts are a ₹2,000+ crore market in India. College fests, corporate events, and fan merchandise drive bulk orders. DTG is better for small custom orders; sublimation wins on bulk sportswear.

DTF (Direct-to-Film) is the emerging alternative — it works on ANY fabric (cotton, polyester, nylon), costs less than DTG per print, and setup is ₹2–4 lakh. Watch this space.
