How to use toner transfer to put graphics on basically anything

I design and build synths, and whenever someone sees one, the first question is almost always the same: “How did you print the labels on the box?” It was even the second most popular comment on the Hackernews post about the Hog.

This post is the long-overdue answer.

The short version: it’s ridiculously simple. There’s a method called toner transfer, and it lets you move laser-printed graphics directly onto almost any surface with a single chemical and a bit of rubbing. Think of it as DIY magic. (Please look up the underlying chemistry if you’re into that—I’ll just cover the practical side.)

Here’s the exact process I use.

How to do it

1. Design your graphic

Anything goes really but beware of too large surfaces. Toner transfer is best for simple labels and small illustrations like logos.

2. Mirror it

You’ll transfer it face-down, so flip it horizontally before printing.

3. Print with a laser printer

Inkjet won’t work. Toner is the key ingredient.

4. Place the graphic on the surface

Make sure the print is facing towards the surface when you put it on. Use some scotch tape to fix the position of the paper.

5. Apply the transfer liquid

Here's the exact product I use in the final post. Brush it over the print with a q-tip. Don't use too much liquid.

Pentart Transfer Solution

Express transfer solution serves for transmission of laser-printed, colored or black and white images to smooth surfaces. (BTW, this is not an ad and I don't get paid for this.)

5. Rub the graphics on the surface

Place it on the target surface and use a credit card (or something with a firm edge) to burnish it. You’ll see the toner getting blurry as it releases from the paper.

That’s it. You’ve just added graphics to whatever you’re building.
