Most logos are designed once, in full colour, on a bright screen. Then the business starts trading and the mark has to go somewhere that cannot do colour at all: a rubber stamp, an official receipt, an embroidered polo, a laser-engraved plaque, a single-ink tarpaulin.
If nobody made a one-colour version, somebody makes one anyway. Usually the supplier, usually in a hurry, usually by converting your artwork to greyscale and hoping. You find out what it looks like when the box of shirts arrives.
Where a one-colour version actually gets used
This is not a theoretical file that sits in a folder. For a Filipino business it comes out constantly:
- Rubber stamps for receipts, delivery slips and permits — one ink, no exceptions.
- Official receipts and invoices printed at a booklet printer in black only.
- Embroidery on polos, caps and aprons, where every colour is a separate thread and a separate charge.
- Silkscreen on shirts and totes, where each colour is another screen and another pass.
- Engraving on plaques, tumblers, signage and giveaways, which has no colour at all.
- Single-colour tarpaulins and vinyl cutting, where the mark is cut from one sheet.
- Foil stamping and embossing on cards, boxes and packaging.
- Faxed, scanned or photocopied forms — still very much alive in permits and government paperwork.
Why greyscale is not the same thing
Converting a colour logo to greyscale looks like the answer and usually is not. Two colours that sit happily side by side in colour often land on nearly the same grey, and the shape between them disappears. A blue icon on a green circle becomes a grey blob.
Gradients are worse. A gradient in greyscale is a smooth ramp, and a rubber stamp or a silkscreen has no way to print a ramp. It has one ink and a yes-or-no decision for every point on the artwork. Anything in between gets rounded off, and what you get back is a smudge where the detail used to be.
A real one-colour version is a redraw, not a filter. Somebody decides which shapes stay, which get outlined instead of filled, and which get dropped because they were never carrying meaning.
How to build one properly
Start from the vector artwork, not from an export. Set everything to solid black on white and look at what has collapsed.
Where two filled shapes have merged into one, separate them: knock a thin white gap between them, or turn the inner shape into an outline. Where a gradient was doing the work, replace it with a flat fill or a simple pattern of lines. Where a drop shadow was giving depth, delete it — a shadow cannot be printed in one ink and only ever muddies the edge.
Then check the counters, the enclosed spaces inside letters like a, e and o, and inside any icon. At stamp size they close up first. If an o is filling in, the stroke around it is too heavy for one colour and needs opening out.
Finally make the reverse: the same artwork in white, meant for a dark background. It is not the black version inverted. Ink spreads on dark surfaces and thin white shapes get eaten, so the white version usually needs slightly heavier strokes to hold.
The test that takes two minutes
Print the one-colour version at 15mm wide on the cheapest printer you own, in black only. That is roughly the size it appears on a rubber stamp or an embroidered chest logo.
Then photocopy that print. Then photocopy the photocopy. Every generation loses detail the same way ink spread does on a stamp pad or thread does on a shirt. If the mark is still readable after three passes, it will survive almost anything a supplier does to it.
If it is not, the problem is in the artwork, and it is much cheaper to find that out now than after two hundred polos have been embroidered.
What to ask your designer for
When you commission or review a logo, ask for these by name. A studio that has done the work will have them ready:
- A one-colour version in solid black, as a vector file.
- A white or knockout version for dark backgrounds and photographs.
- Both of them tested at around 15mm wide, not just on screen.
- A note on the smallest size the mark should ever be used at.
- The same versions as transparent PNGs, for suppliers who cannot open vectors.
What we do
Every logo we make comes with the one-colour and white versions built rather than converted, because they are not optional extras — they are most of where the mark actually lives. That is true at ₱2,999 for a Starter logo and at every level above it.
If you already have a logo and no one-colour version, that is a small job on its own and worth doing before your next print run rather than after it.
Common questions
- What is a one-colour logo version?
- It is your logo redrawn to work in a single ink, usually solid black, with no gradients, shadows or overlapping colours. It is not the colour logo turned to greyscale — shapes that were separated by colour have to be separated by outlines or gaps instead, or they merge into one blob.
- Why can I not just print my colour logo in black and white?
- Because colours that contrast on screen often turn into nearly identical greys, and gradients cannot be printed by a stamp, a silkscreen or an embroidery machine at all. Those processes have one ink and a yes-or-no decision at every point, so anything in between gets flattened and the detail is lost.
- Do I need a white version too?
- Yes, if your logo will ever sit on a dark shirt, a photograph, a black tarpaulin or a dark website footer. And it should be built rather than inverted: ink and thread spread on dark surfaces, so white artwork usually needs slightly heavier strokes than the black version to survive.
- How small can a one-colour logo go?
- Test it at about 15mm wide, which is roughly a rubber stamp or an embroidered chest logo. Print it, then photocopy the print twice. If it is still readable, it will hold up on a stamp pad, a silkscreen or a shirt. If it fills in, the strokes are too heavy or the counters too tight.
- My supplier says they can make the one-colour version themselves. Should I let them?
- They can, and they will, but they will do it in a few minutes without seeing your other artwork, and you will not see the result until the job is delivered. It is your mark appearing on two hundred uniforms. Better to hand them a file you have already approved.
