Best Ink Types for Custom Bag Printing

Most European bag factories work with two ink families in practice, not seven.

For bulk orders, they run screen printing ink, either plastisol or water-based, pushed through a mesh screen and heat-cured onto the cotton. For full-colour, photographic, or very small runs, they switch to digital printing ink (DTF), jetted onto a film and heat-pressed on instead.

Everything else- foil, puff, discharge- exists too, but it's a specialty request, not a default, and it usually comes with a higher minimum order quantity than a standard print.

This guide focuses on the ink itself. If you want the broader comparison of the printing methods, see Digital Printing vs Screen Printing on Tote Bags, or for the full range of techniques factories offer, see Printing Methods for Cotton Tote Bags.

Screen Printing Ink: The Default for Bulk Orders

Screen printing ink is a thick, coloured paste pushed through a fine mesh screen, one colour and one screen per pass, then heat-cured so it bonds to the cotton.

It's the method almost every European factory defaults to once an order moves past a handful of pieces, because the screen setup cost is fixed and gets cheaper per bag the more you print.

Two ink bases cover the vast majority of that work.

Plastisol ink

Plastisol is a PVC-based paste ink suspended in a plasticiser rather than water.

It cures at around 150 to 160°C and sits as a thin, flexible layer on top of the fabric, which is exactly why it gives such opaque, exact colour matches, including precise Pantone matching, and such long wash durability: a properly cured plastisol print on cotton canvas comfortably survives 50 or more washes without cracking.

It's the standard choice for bulk logo runs and flat-colour artwork, and it's what most factories quote by default unless you ask for something else.

Water-based ink

Water-based ink swaps the PVC base for a water-and-binder mixture, so the pigment absorbs into the cotton fibres instead of sitting on top of them.

The print is noticeably softer to the touch, almost invisible on the fabric, which is why it's the ink of choice when a soft-hand feel matters or when sustainability is part of the brief; the water base also avoids the plasticisers used in plastisol.

A properly cured water-based print still handles 30 to 40 washes, only slightly behind plastisol, and it's become the standard eco-conscious swap across EU factories responding to REACH and GOTS-driven demand rather than a niche request.

Digital Printing Ink (DTF)

Digital printing ink skips screens entirely.

In DTF (direct-to-film) printing, a water-based pigment ink is jetted onto a film, coated with an adhesive powder, and heat-pressed onto the bag. There's no per-colour cost and no screen to cut, so factories reach for it in two situations:

• the design is full-colour or photographic with detail that would need a dozen screens to reproduce
• the run is too small to justify the fixed screen setup cost in the first place, think samples or orders under roughly 25 to 50 pieces.

Outside those two cases, screen printing ink stays cheaper and, on cotton, tends to hold up better over repeated washing.

DTF isn't the same as DTG (Direct-to-Garment) printing, another digital technique some factories offer — see our DTG printing guide for how that one differs.

Screen Printing Ink vs Digital Printing Ink: Comparison Table

Ink type	Made of	Feel on cotton	Durability	Best for	Typical MOQ
Plastisol	PVC paste + plasticiser + pigment	Slight texture, sits on top	50+ washes	Bulk logo runs, exact Pantone colours	Standard
Water-based	Water + binder + pigment	Very soft, absorbs into fibres	30-40 washes	Soft-hand totes, eco-conscious orders	Standard
DTF (digital)	Water-based pigment ink + adhesive film	Slightly firmer over large solid areas	Good; large solid areas wear first	Full-colour, photographic designs, small batches	Standard, no minimum for setup, but per-unit cost stays flat

Specialty inks (discharge, puff, metallic, foil) aren't in this table because they're not a default option at most factories. See the note below.

Feel and Durability: What You'll Actually Notice

On the bag itself, the difference between these inks is mostly about touch and wash life, not appearance.

Plastisol has a slight, cured texture you can feel under your fingers and holds colour longest through repeated washing.

Water-based ink sits almost flush with the fabric and moves with it, so it feels closer to an unprinted cotton bag, at a small cost to long-term wash durability.

DTF sits somewhere between the two: fine detail and small text feel close to the fabric, but large solid-colour blocks pick up a slightly firmer, more plastic feel where the adhesive layer is thickest, and that's usually the first place a print shows wear.

Which Ink Will You Get by Default?

Most European factories apply a simple rule, and it's worth knowing before you ask for a quote.

1) If your design uses a handful of flat colours and you're ordering in bulk, you'll be quoted screen printing ink, plastisol, unless you specifically ask for the softer water-based option.

2) If your design is full-colour, photographic, or the run is small, expect digital printing ink (DTF) instead.

Each additional flat colour in a screen-printed design needs its own screen, which is why pricing scales with colour count rather than staying flat, and it's also why factories steer bulk orders toward screen printing rather than digital by default.

Choosing your actual print colours is the next decision — see our guide on how to choose print colours for your tote bags.

A Note on Specialty Inks

Discharge, puff, and metallic or foil inks exist, and some European factories offer them for premium or event runs: discharge for an ultra-soft print on dark cotton, puff for a raised logo, foil for shine on a gift bag.

None of them are a default recommendation here, and that's deliberate: because factories don't keep these set up as standard, the minimum order quantity for a non-classical ink usually runs higher than for a standard plastisol or water-based print, so it's worth confirming the minimum order quantity before designing around one of these finishes for a small order.

Frequently Asked Questions

What's the difference between screen printing ink and digital printing ink?

Screen printing ink is a thick paste pushed through a mesh screen and heat-cured onto the fabric, while digital printing ink is jetted onto a film and heat-pressed onto the bag, with no screens and no limit on the number of colours.

Which is more durable, screen printing ink or digital printing ink?

Plastisol screen printing ink is the most durable option, comfortably surviving 50 or more washes. Water-based screen printing ink holds up for 30 to 40 washes. Digital printing ink (DTF) is durable for normal use, but large solid-colour areas tend to show wear first.

Is DTF as good as screen printing for custom bags?

For full-colour or photographic designs and small runs, DTF is the better and cheaper option since there's no per-colour cost. For bulk orders with a handful of flat colours, screen printing ink is cheaper per bag and holds up better over time.

Can factories match my exact brand colour?

Yes, but reliably only with screen printing ink, specifically plastisol, which supports precise Pantone matching. Digital printing ink gets close but works from the design file's colour values rather than a matched ink, so small variation is more likely.

Do specialty inks like foil or puff have a higher minimum order quantity?

Usually, yes. Because factories don't keep discharge, puff, or metallic/foil set up as standard production lines, they typically require a higher minimum order quantity to justify the extra setup than a standard plastisol or water-based print does.
