Introduction

The term conference embroidery or embroidered conference wear refers to one kind of Academic embroidery wear.

Conference embroidery can:

1. Display figures and diagrams, turn a person into some kind of walking poster
2. Make strong statements
3. Display logos of favorite projects, software, your organization etc.

It's purpose is to broadcast ideas or identity and get other conference participants interested in what the wearer of conference embroidery has to say.

Various people matching technology and concepts does exit e.g. for business speed dating or as part of CSCL scripts in education. Such location-based matchmaking can be implemented with various specialized devices. Conference wear is an attractive "low tech" alternative. The principle is the same: It should raise the awareness of the presence of others that share similar interests within a reduced spatial area, e.g. a conference building.

I believe that I was the first person trying to embroider a power point slide and to publish the method. I also used other sources to create conference embroidery, e.g. vector graphics programs.

General method for producing a walking conference poster

Below are some steps that you may go through. Some are optional

• Use any kind of drawing program to create the vector art.
• Make sure to use simple flat graphics, e.g. no bevels and other such filters
• You also can use a tool like powerpoint and then export the graphic as EMF and import it to a vector graphics program.
• Simplify all the vectors in the drawing program (optional)
• Translate fonts to vectors in the drawing program (optional)
• Import to the embroidery software and generate stitch sections.

An other alternative is to write a script that will parse the Presentation file and produce vector graphics in some popular format or directly an embroidery format.

Power Point slides for embroidery

The power point

In order to embroider powerpoints, there are a few simple rules to follow on the Power Point side:

• Keep the shapes simple in terms of effects, i.e. don't use any bevel filters and such
• We also suggest removing shape outlines from larger areas. In embroidery design software you always can add a border to shape if you need one.
• Plan for vector art that is not stacked. While you can simplify designs through solid constructive geometry techniques, it is best to plan ahead. In other words, avoid having areas on top of other ones, else the embroidery will become heavy
• Adapt font size. E.g. for a 14x20 hoop area I use 36pt fat True Type fonts. Calibri works well for example
• Use fat lines (3pt) unless you plan to stitch these with narrow running stitches. If you plan to use satin stitches, lines must be even fatter.

Below is an example of simple slide that follows these principles:

Export and simplify the vectors

Depending on the capabilities of your embroidery suite, we suggest to import the *.EMF to a professional vector drawing program like Illustrator. You then should simplify the shapes (if needed) and also make sure that the fonts are being translated to vector shapes.

In Illustrator CS5:

(1) After loading the EMF, select ALL (CTRL-ALL) and ungroup, e.g. menu Object-Ungroup

(2) You now should transform letters into vectors. Although this is not strictly necessary, we recommend it since your embroidery program will probably do it anyhow and not as well as Illustrator.

• Hold down the SHIFT key (not CTRL) and select all words,
• then right-click->Create Outlines. If it doesn't work, select fewer words (you may have selected another object).

Convert fonts to normal vector shapes

The result should look like this. As you can see, each letter is now defined by Bezier control points. There seem to quite many. This is IMHO due to the fact the Calibri font used is irregular and that's the reason why it is prettier than Arial.

Converted fonts to normal vector shapes

Note:

• I'd rather explain how to do this with Inkscape. However there are two problems: Inkscape support for EMF is not very good. Commercial embroidery programs can't read SVG and therefore you will have to go through through Illustrator anyhow.

For doing this with a good and free embroidery design suite, read Stitch_Era - digitizing complex vector images
