Discharge print for corporate merch in Türkiye
Discharge print removes the dye from a coloured garment and replaces it with a new colour, rather than overlaying ink on top. The result is a soft-hand print on dark garments with no plastisol feel. This page covers how discharge works, which garment dyes respond to it, and the trade-offs against standard silkscreen on dark tees.
How discharge printing works on a coloured garment
Discharge print uses a water-based ink that contains a discharge agent — typically zinc formaldehyde sulfoxylate or a non-formaldehyde alternative — which bleaches out the dye in the garment where the ink is printed. A replacement pigment is mixed into the ink so that as the discharge agent removes the original dye, the new pigment soaks into the fibres. The result is a printed mark that is the new colour rather than an overlay.
Because the new colour sits in the fabric fibres instead of on top of them, discharge prints feel soft to the touch — there is no plastisol ink layer, no DTF film, no CAD-cut vinyl. On a 180 GSM cotton tee, a well-executed discharge print feels essentially indistinguishable from the unprinted fabric. On a 280 GSM fleece, the print sits in the loops without filling them.
Discharge printing only works on garments dyed with dischargeable dyes. Reactive dyes (used on most high-quality cotton) discharge cleanly. Pigment-dyed garments discharge partially and the results are uneven. Garments dyed with sulphur dyes (some deep blacks and navy blues) discharge to a reddish or orange tone rather than white. We test every new garment dye on a sample before committing the production run.
Substrates and garment fit
Cotton is the classic discharge substrate. Ringspun cotton, combed cotton, organic cotton, recycled cotton — all discharge cleanly when reactive-dyed. We work with mills in Bursa, Kahramanmaraş and İzmir that supply discharge-friendly cotton blanks; for programs that need a specific dye recipe we order custom-dyed blanks with 15-25 working day lead times.
Cotton-poly blends (above 80% cotton) discharge partially — the cotton component discharges and the polyester component doesn't, leaving a slightly heathered effect. For programs that need the soft hand of discharge on a performance fabric, we usually suggest DTF instead because it sits cleanly on polyester.
Fleece, French terry, jersey and interlock knit fabrics all discharge well. Woven fabrics discharge less cleanly because the tighter weave resists ink penetration; for woven corporate apparel programs we usually suggest standard silkscreen or DTF instead.
Discharge colours and Pantone matching
Discharge inks can be mixed to most Pantone PMS references, but the achievable colour gamut is narrower than standard silkscreen on white garments. Light colours and bright colours work cleanly. Deep blues, deep greens and deep reds shift slightly because the underlying dye removal tints the new colour. We usually suggest a strike-off on the production garment for brand-precise colour matching.
For dark garment programs that need a white logo, discharge is often the right answer because it gives a true white rather than the slightly off-white that plastisol white ink achieves on dark cotton. For coloured logos on dark garments, discharge gives a softer, more vintage feel than plastisol, which is the right answer for fashion and lifestyle brands.
Discharge prints tend to fade slightly over time and with washing, which is part of the vintage aesthetic. The mark lightens by about 10-15% over the first 10 wash cycles and then stabilises. For corporate programs that need a more durable colour, we layer a small percentage of standard pigment on top of the discharge ink, which extends colour life at a slight cost to hand-feel.
Wash durability and care guidance
Discharge prints survive 30-50 domestic wash cycles before visible dulling. The keys are correct cure temperature (160°C for 90 seconds in a conveyor dryer or 15 seconds in a heat press), even heat distribution, and waiting 24 hours before the first wash. We supply a care card with every discharge-printed apparel order: wash inside out at 30°C, line dry, do not iron directly on the print.
Discharge prints have a slightly different wash-fastness profile than standard silkscreen. The new colour is in the fibres rather than on top, so it fades more like the garment colour than like an ink. This is part of the vintage aesthetic; for programs that need a more durable mark, we suggest DTF or standard silkscreen.
For uniform programs that go through industrial laundering at 60-85°C, discharge prints have a shorter service life than standard plastisol. We flag this at the brief stage and offer standard silkscreen or DTF alternatives for heavy-duty uniform programs where discharge durability isn't sufficient.
Run sizes, lead times and unit economics
Discharge print runs on the same silkscreen presses as standard apparel programs, with a dedicated discharge ink mixing station and conveyor dryer. Run sizes start at 30-50 units per design, with the per-unit price dropping meaningfully above 100 units. Below 30 units we usually suggest DTF for cost reasons.
Lead time is 10-14 working days from written strike-off approval: 2-3 days for ink mixing and strike-off, 5-7 days for bulk production, 2-3 days for finishing and pack-out. Express 7-10 day turnarounds are available on repeat orders with held blanks.
For high-volume discharge programs (1,000+ units), we can sometimes suggest discharge combined with a printed highlight — a small accent layer on top of the discharge base that adds dimensional detail to the mark. This is more cost-effective than a second full-colour silkscreen layer and reads as a more refined product.
Discharge versus standard silkscreen on dark garments
Standard silkscreen on dark garments requires a white underlay (a base layer of white ink) followed by the colour layers on top. The white underlay gives full opacity but adds stiffness and weight to the print, and the colour layers sit on top of the underlay rather than in the fabric. The result is a print that feels thicker than the surrounding fabric.
Discharge replaces the white underlay by removing the dye and replacing it with the desired colour. The print sits in the fabric with no overlay, which gives a softer hand-feel but slightly less colour brightness than a plastisol white underlay. For programs where hand-feel matters more than colour brightness, discharge wins. For programs where colour brightness matters more than hand-feel, standard silkscreen with a white underlay wins.
For mixed programs (some pieces on white, some pieces on dark), we run silkscreen on the white pieces and discharge on the dark pieces, with a single artwork file that accommodates both production methods. This is a common corporate scenario — a uniform program with a white version and a navy version, for example.
Where we run discharge print in Türkiye
Discharge production sits on the same silkscreen presses as our standard apparel programs in Başakşehir and İkitelli, with a dedicated discharge ink mixing station in Levent and a conveyor dryer in Başakşehir. Cotton blanks are sourced from Bursa, Kahramanmaraş and İzmir partner mills that supply discharge-friendly cotton.
For corporate apparel programs delivered to İstanbul offices, Ankara government and diplomatic addresses, İzmir trade-show venues, and Antalya resort venues, we run hand-delivery for high-value orders and tracked road freight for larger volumes.

Frequently asked questions
What is the minimum order for discharge print?
Discharge print starts at 30-50 units per design on dark garments. Below 30 units we usually suggest DTF for cost reasons. The per-unit price drops meaningfully above 100 units.
How long does discharge print production take?
A standard 100-unit, four-colour corporate apparel order with discharge takes 10-14 working days from written strike-off approval. Express 7-10 day turnarounds are available on repeat orders with held blanks.
Which garments work with discharge print?
Reactive-dyed cotton (ringspun, combed, organic, recycled) is the classic discharge substrate. Cotton-poly blends above 80% cotton discharge with a slight heather effect. Pigment-dyed and sulphur-dyed garments discharge poorly. We test every new garment dye on a sample before committing a production run.
Can discharge print match a corporate Pantone colour?
Most Pantone references are achievable but the gamut is narrower than silkscreen on white. Deep blues, deep greens and deep reds shift slightly because the dye removal tints the new colour. We suggest a strike-off on the production garment for brand-precise matching.
Is discharge print as durable as standard silkscreen?
Discharge prints survive 30-50 domestic wash cycles. The new colour is in the fibres and fades more like the garment colour than like an ink. For programs that need a more durable mark, we suggest DTF or standard silkscreen with a white underlay.
