Designing custom printed gummed paper tape comes down to three things: work with a design that repeats along the roll, keep your artwork inside a 40mm print band, and choose colours that suit either white or kraft tape. Get those right and your branded tape will seal every box cleanly while looking sharp on the shelf and the doorstep. This guide walks through exactly how the print process shapes your artwork, so your first order arrives looking the way you pictured it.
At Fast Printed Tapes we print onto the tape itself using full-colour, water-based digital inkjet, and understanding a few simple rules up front makes the difference between artwork that sings and artwork that fights the format.
What custom printed gummed tape actually is
The product we print is water-activated gummed paper tape, 48mm wide, available in white or brown kraft, and in standard or reinforced weights. It is a plastic-free, paper-based tape that bonds to the box when the gum is wetted, forming a permanent seal. If you are weighing the reinforced option against the standard one, our guide on reinforced versus standard gummed paper tape covers when the extra fibreglass layer is worth it.
Crucially, the branding prints onto the strip of tape only, not across the whole carton. The rest of the box stays plain. That is why printed gummed tape looks so tidy on a parcel: a clean band of colour running along the seam, with the natural board on show around it.
Design rule one: your artwork repeats along the roll
Printed gummed tape is not a one-off sticker. Your design is printed as a continuous repeat that runs the length of the roll, so the same motif appears again and again as the tape unwinds. Between each repeat there is a fixed gap of roughly 10cm to 13cm that cannot be reduced. This is simply how the print and cutting process works, and it is worth designing with rather than against.
In practice, this means a compact, self-contained motif works far better than a single sprawling graphic. Think of a logo, a short tagline, or a small pattern that looks deliberate when it recurs every 30cm or so. Because most parcels only need a strip of tape 20cm to 40cm long to seal the top seam, you want your key branding to land within any short length someone tears off. A design built around a tight repeat guarantees the logo shows up on every parcel, whatever length is cut.
Design rule two: keep everything inside the 40mm print area
The tape is 48mm wide, but the maximum print height is 40mm. That leaves a small unprinted margin along the top and bottom edges, which is intentional and helps keep the print clean and consistent. Position tolerance is around 2mm, so we advise against designs that rely on ink running exactly to a hard edge.
A few practical notes on the print area:
- Give artwork breathing room. Keep important elements a couple of millimetres inside the 40mm band so nothing important sits on the very edge.
- Mind the roll end. Roughly the last metre of a 50m roll prints blank, which is normal and simply reflects where the print run tails off.
- Avoid tiny reversed text. Fine detail reversed out of a solid colour can close up; bolder shapes reproduce more reliably.
- Design for a strip, not a sheet. The canvas is long and narrow, so horizontal, banner-style layouts suit it best.
Design rule three: colour, and why there is no white ink
We print in full-colour CMYK using water-based inks. There is one rule that surprises people the first time: there is no white ink. Any white in your design is created by the tape colour showing through, not by ink being laid down. On white tape that is no problem at all, because white areas simply stay as bare white paper. On brown kraft tape, however, a shape you intended to be white will appear as brown, because there is no ink to make it white.
That single fact drives most of the colour decisions. If your logo depends on white elements, white tape is usually the safer base. If you love the natural, eco-friendly look of kraft, design for it deliberately rather than dropping a white-based logo onto brown.
Designing for kraft tape
Kraft is warm and slightly textured, so printed colours read a little muted and darker than they would on white. Rich, saturated colours such as deep reds, forest greens and navy hold up well; pale pastels and anything relying on white detail tend to disappear. Kraft is a natural partner for sustainable branding, and pairs neatly with the plastic-free story we cover in our guide to recyclable gummed paper tape.
Designing for white tape
White tape behaves much more like paper you would print at home: colours appear brighter and truer, and white detail in your logo stays white. It is the more forgiving choice for detailed or multi-colour artwork, and the better base when precise brand colours matter to you.
What we do not print
To keep expectations clear, gummed paper tape is the only tape we custom-print. We do not print self-adhesive parcel tape, barrier tape or warning tape, and we print onto the tape rather than onto the box. There is also no foiling, embossing, debossing, spot-UV, metallic ink, guaranteed Pantone matching or bespoke sizing. Keeping the format simple is exactly what lets the tape stay affordable and quick to turn around. If branded tape is part of a wider e-commerce refresh, our piece on branded tape for e-commerce is a useful companion read.
A quick pre-flight checklist
Before you send artwork over, run through this short list:
- Is the design built as a repeating motif rather than one long graphic?
- Does everything important sit inside the 40mm print height?
- Have you chosen white or kraft tape to suit the colours in your logo?
- Are you relying on white ink anywhere? If so, switch to white tape.
- Is the artwork bold enough to survive a warm, water-based print?
It is also worth remembering that tape adds a little to a parcel's finished size. Royal Mail measures the packed and sealed item, so if you are close to a size band the tape counts too, as their parcel size guidance makes clear.
Frequently asked questions
Can I print white text on brown kraft tape?
No. There is no white ink in the process, so any white in a design is produced by the tape colour showing through. On kraft tape a white element would print as brown. If your branding needs white, choose white tape instead.
Why is there a gap between each printed repeat?
The design repeats continuously along the roll with a fixed gap of about 10cm to 13cm between repeats. This gap is part of how the tape is printed and cannot be reduced, so it is best to design a compact motif that looks good each time it recurs.
How much of the tape width can I actually print on?
The tape is 48mm wide and the maximum print height is 40mm, leaving a small clear margin at the top and bottom edges. Keeping key elements a couple of millimetres inside that band gives the cleanest result.
What file should I supply for the best print?
A high-resolution vector or a large, sharp raster file in CMYK works best, using bold shapes and colours rather than fine reversed detail. Because printing is water-based on paper, strong, confident artwork reproduces more reliably than delicate line work.
Is printed gummed tape as strong as plain tape?
Yes. Printing does not weaken the seal. Water-activated gummed tape bonds into the cardboard fibres for a tamper-evident seal, and the reinforced version adds fibreglass strands for heavier cartons. You can read more in our guide to why gummed paper tape seals boxes better.
Ready to design your branded tape?
Custom printed gummed tape turns a plain box into a branded unboxing moment, and it is far easier to design well once you know the repeat, the 40mm print area and the no-white-ink rule. When you are ready, explore your options on the custom printed gummed tape page, or browse more guides over at Fast Printed Tapes. Design with these simple rules in mind and your first roll should arrive looking exactly as you imagined.
