Does my logo work in one color? Five checks before it goes on a truck

Set the whole logo to solid black and print it. If the name still reads and the mark is still one shape you'd recognize on a truck door, it works in one color. If it turned into a smudge, it will cost extra at every sign shop and embroiderer you send it to. Most logos get made on a screen and judged on a screen. Then one goes to the sign shop and comes back as a quote for four layers of vinyl, and the polos arrive with the outline stitched shut. The five checks below catch that before the invoice does. They take an afternoon and most of them cost nothing. A trade logo spends most of its life away from a screen: cut from vinyl for the truck door, stitched into a polo, printed in black on the invoice, painted on a yard sign, shrunk to a thumbnail on Google Maps, and every one of those places is cheaper and cleaner when the logo is one solid shape. The color version is for the website. The one-color version is the one you'll use most, so that's the one to test.

Open the logo, set every part of it to black, and print it on plain paper. No greys and no tints. A gradient turns into a smudge or drops out. A glow or drop shadow turns into a black blob around the shape, and a name set in a colored box comes out as one black rectangle. What's left on the page is what a rubber stamp, a one-color print run, or a photocopied flyer on a break-room wall will show. If you can still read the name and recognize the mark, it passes.

Print it again at one inch wide, which is roughly the size it will be on a business card, a pen, an invoice header, or the round profile picture on a Facebook page. Thin lines vanish and any small text under the name turns to fuzz. A mark with a lot of detail, a house with shingles and a chimney and smoke, comes out as a grey square. Look at the print from arm's length, then have someone who has never seen the logo tell you what it is. If they can't, the detail is doing nothing at that size and will cost extra every time it's stitched or cut.

This is the check that costs money when it fails. Vinyl lettering for a truck door is cut by a plotter and then weeded by hand: someone picks away every piece of vinyl that isn't part of the logo. Thin strokes, tiny gaps inside letters, and fine serifs either tear during weeding or peel off the door in the first Nebraska winter. Ask a sign shop in Omaha or Bellevue what it would cost to cut the logo at door size and listen to the answer. If they ask for a simplified version, or quote extra for the weeding, the logo has strokes that are too thin. If the shop cuts the logo rather than printing it, every extra color is a separate sheet, lined up on the door by hand, and the layering adds to the bill.

Embroidery shops usually price by stitch count, and extra thread colors add to it. Each color is a thread change, and a gradient becomes a hard step between two threads, because thread doesn't fade. Small text under the name doesn't stitch cleanly at all. Send the logo to an embroiderer and ask two questions: how many thread colors does it need, and will anything have to be removed to stitch it on a polo chest. A logo that comes back needing one or two threads with nothing dropped passes. One that needs a handful of threads and loses the tagline was designed for a screen.

Put the logo on the truck, or tape a print of it to the door at the size it would be, and walk to the far side of the parking lot. Take a photo with your phone, no zoom. That photo is what a customer sees when the truck is parked outside a neighbor's house in Papillion, and it's what gets posted in a Facebook group when someone asks who did the work. If the name is readable in that photo and the mark is one shape you'd recognize again, it passes. If the name is lost in the color and the shadow, that photo is still the first thing a lot of customers see, so it's worth fixing.

• Gradients: they print as bands, stitch as hard steps, and can't be cut in vinyl at all
• Glows and drop shadows: they read as dirt in black and add a color everywhere else
• Outlines around letters: the gap between the outline and the letter fills in at small sizes, and the letters go bold and blurry
• Four or more colors: four sheets of cut vinyl, four thread changes, and extra on the bill at every shop that cuts rather than prints
• Script fonts: the thin connecting strokes peel off a door first and disappear first in a photo
• A tagline set small under the name: unreadable at one inch and hard to stitch at any size
• Chrome effects, bevels, and photo-real detail: none of it survives being flattened to one color

A logo can fail most of these and still be a logo customers know. Usually it just means nobody sent it to a sign shop before it went on the truck. The customers who already know the mark are still worth keeping, and the right fix usually keeps them.

1. 01

   Find the biggest file you have

   If you have an AI, EPS, SVG, or PDF, use that. If all you have is a JPEG from the last designer or a screenshot of the truck, that's fine for the test, and it tells you something already: the vector file belongs on the list of things to get back.

2. 02

   Make the black version

   Any free image editor will do it. Set everything to black on white and look at what's left. If you can't get the background out because the file is a JPEG, that is a result too.

3. 03

   Print it twice

   Once at full size on a sheet of paper and once at one inch. Put both on the fridge for a day and see which one you stop being able to read.

4. 04

   Ask the two shops

   Email the logo to a sign shop and an embroiderer with one line: what would this cost to cut at door size, and how many threads to stitch it. Their answers are the test result. Asking for a quote usually costs nothing, and the shop that wants the job will tell you what it needs.

5. 05

   Shoot the truck

   One phone photo from the far side of the lot, straight from the camera. Look at it on the phone, where customers will, and see whether the name reads.

There are two kinds of fix, and which one you need depends on what failed. A refresh keeps the mark customers already recognize and takes out the printing problems: the gradient becomes a flat color, the glow goes, the outline is either removed or thickened so it holds at one inch, the small tagline comes off, and everything is redrawn as clean vector. A rebuild is for a logo that fails every check, where the type is a stretched script, the mark is a stock icon, and there is no vector file to start from. There we keep the name and whatever customers remember, which is usually the color and the general shape, and draw a mark that passes all five from the start. Both come back as clean vector with the one-color version in black and in white, and the files are yours. The branding page lists the full file set, and the LOGO REFRESH line on the price sheet is $75 to clean up the mark you have; a rebuild is a new logo, Spark at $150.

If you'd rather have us run the checks, send the logo in whatever form you have, a photo of the truck, and a photo of a shirt if the logo is on one. Say which of the five it failed, if you already know. You get a reply within one business day, Monday to Friday, saying whether it needs a clean-up or a rebuild and what that costs. Nothing gets redrawn until you say so, and the files are yours when the last invoice is paid.

LOGO REFRESH IS $75 ON THE PRICE SHEET. A REBUILD IS SPARK, $150. YOU OWN THE FILES.
