Direct-to-Garment (DTG) printing for B2B merch programs in Armenia

Five structural blocks for the DTG method

1. Pretreatment, white-ink underbase, and per-garment setup overhead

Every DTG order begins with garment pretreatment — a liquid pretreatment solution (typically a mixture of water, a cellulose thickener, and a humectant) sprayed or padded onto the print area to hold the ink on the fabric surface and prevent bleeding into the fibres. Dark garments (black, navy, charcoal, deep red) require an additional white-ink underbase pass before the colour pass; light garments skip the underbase. Pretreatment chemistry is matched to the garment weight — roughly 18-22 grams of pretreatment solution per A4-sized print area on a 180-200 GSM cotton tee. The supplier's pretreatment, white-ink, and colour-pass are documented on the per-run QC log. Per-garment setup overhead (pretreatment, platen loading, head priming) is roughly 600-1,000 AMD and is independent of artwork complexity.

2. Per-piece AMD cost band by run volume

The per-piece AMD cost band for DTG depends on unit quantity, garment colour (dark vs light), artwork size, and pretreatment chemistry. Single-position DTG on a 180-200 GSM cotton tee at light colour at 25 units runs roughly 4,200-6,800 AMD per piece. At 50 units, roughly 3,500-5,400 AMD. At 100 units, roughly 2,900-4,400 AMD. At 200 units, roughly 2,500-3,800 AMD. Dark-garment DTG with white underbase adds roughly 800-1,500 AMD per piece across the run. Two-position DTG (front + back) on the same tee at 50 units runs roughly 6,500-9,500 AMD per piece.

3. Production routes across Yerevan and Istanbul

Yerevan DTG shops handle 10-200 unit runs with typical lead times of 5-10 working days from production release lock, delivered to named Yerevan drop points. Istanbul DTG partners handle 200-1,000+ unit runs with lead times of 10-18 working days door-to-Yerevan. DTG does not scale to Guangzhou-tier volumes economically because the per-garment setup overhead offsets the labour-cost advantage at high volume. Most Armenian B2B buyers route 10-200 unit personalised drops through Yerevan DTG shops and 200+ unit bulk runs through CMYK screen process printing or DTF transfer instead.

4. Print head technology, ink chemistry, and Pantone approximation

Yerevan DTG shops typically use Epson-based piezo print heads (F2100, F2200, G6000) with water-based pigment inks meeting OEKO-TEX Standard 100 and GOTS requirements. Resolution up to 1,440 x 1,440 DPI supports complex illustrations and photoreal prints. Brand colours reproduced in DTG land within a Delta-E tolerance band of roughly 2-3 against their Pantone reference — comparable to CMYK screen process printing and acceptable for most corporate apparel programs. The supplier confirms ink chemistry and supplies a Pantone bridge on request.

5. Defect tolerance, 5% overrun buffer, and lifetime expectation

Armenian B2B DTG orders typically carry a 1-2% defect tolerance with full replacement at supplier cost for any unit that fails position-print QC. The supplier holds a 5% overrun buffer on the order quantity to absorb the defect process. DTG decorations on cotton withstand 30-50 industrial laundry cycles without visible degradation when cure temperature and pretreatment are correctly specified — slightly less durable than CMYK screen process printing because the ink sits on the fibre surface rather than being absorbed into it. On cotton tees, the typical lifecycle is 2-4 years under active use.

Technical specs, common pitfalls, and process workflow

Print head types, resolution, and pretreatment chemistry

Yerevan DTG shops typically use Epson F2100, F2200, or G6000 print heads with piezo-electric drop-on-demand technology. Resolution settings typically run 1,440 x 720 DPI for production work and 1,440 x 1,440 DPI for premium photoreal work. Pretreatment solution is a proprietary mixture (commercial names include Image Armor, Firebird, and One-Step) applied via spray gun, pad machine, or pretreatment tower. Cure temperature runs 160-180°C for 90-180 seconds in a conveyor dryer or heat press. The supplier documents all chemistry and machine parameters on the per-run QC log.

Common buyer pitfalls

Five pitfalls recur in Armenian B2B DTG orders. First, supplying an artwork file at 72 DPI instead of 300 DPI — DTG reproduces the resolution literally, and 72 DPI shows visible pixels at print size. Second, requesting DTG on a cotton-poly blend below 80% cotton — the polyester fibres do not absorb the ink and the print looks washed-out. Third, omitting the white-ink underbase spec for dark garments — colours on a black tee without an underbase look muted. Fourth, expecting Pantone-accurate brand-colour reproduction on a DTG strike-off — DTG is closer to CMYK approximation, not Pantone spot. Fifth, ordering 1,000+ units via DTG when CMYK screen process printing would be 30-50% cheaper per piece.

Process workflow at a Yerevan DTG shop

A typical Yerevan DTG workflow runs five stages. First, artwork file check and RIP processing (half-day). Second, garment receipt, pre-press flattening, and pretreatment application (half-day to one day). Third, platen loading, head priming, and print run (1-3 days for 25-200 units). Fourth, cure in a conveyor dryer or heat press (1-2 hours per batch). Fifth, final QC, fold, and pack (half-day). The full 25-200 unit cycle takes 4-7 working days plus the 1-2 day buffer for receipt and delivery to named Yerevan addresses.

Anonymised case study: personalised conference attendee apparel

An Armenian business-incubator ran a 180-attendee conference and wanted each attendee to receive a personalised tee with name + role on the back. The buyer supplied a CSV with 180 name+role pairs and a single template artwork. The supplier generated 180 personalised PNG files, ran them through a Yerevan DTG shop in 7 working days, and delivered to the conference venue. Per-piece cost was roughly 4,800 AMD including pretreatment, white-ink underbase, and personalised packaging. The buyer re-ordered 60 additional personalised units post-event for VIP attendees at roughly 5,200 AMD per piece (lower-volume surcharge).

Compliance: OEKO-TEX, GOTS, and water-based pigment inks

Two certifications dominate Armenian B2B DTG orders. OEKO-TEX Standard 100 on the underlying fabric is the minimum requirement for corporate apparel programs. GOTS (Global Organic Textile Standard) covers the organic-cotton supply chain from field to finished garment; required when the campaign explicitly markets organic cotton. Water-based pigment inks are the default ink chemistry on cotton because they meet EU and EAEU textile-import standards and the OEKO-TEX/GOTS chemistry requirements. Pretreatment solutions carry their own safety data sheet and must be documented on the per-run QC log.

DTG vs CMYK screen process printing

DTG and CMYK screen process printing are complementary methods, not substitutes. DTG is the right method for short runs (10-200 units), personalised or variable artwork, dark-garment photoreal prints, and sample runs before bulk production; per-piece cost is higher but the screen-setup overhead disappears. CMYK screen process printing is the right method for long runs (200+ units), identical artwork across all units, and unit-cost-sensitive campaigns; per-piece cost is 30-50% lower at 500+ unit volumes. Most Armenian B2B buyers route personalised drops and samples to DTG and bulk photo-driven campaigns to CMYK screen process printing.

End-of-life and recycling routes

DTG-printed cotton apparel is recyclable through textile recycling centres in Yerevan and the marzes; cotton fibres are recovered and re-spun for lower-grade textile applications. DTG ink chemistry (water-based pigment) does not introduce contaminants that complicate recycling relative to standard cotton garments. Buyers coordinate final collection transport through the recycling centre or a textile processing partner of their choice.
