## Introduction[edit | edit source]

Computerized embroidery, also called Computer-controlled embroidery or simply machine embroidery is a kind of Computer-aided design and manufacturing (CAD/CAM).

See the  Machine embroidery portal page for a list of all embroidery-related topics.

In this short article, we shall introduce some basic principles. More technical information about computerized embroidery is available in other articles available indexed in the computerized embroidery category. Computerized embroidery machines are specialized machines that can create embroidery from computerized designs. Such machines exist for the home market, for the small independent professional and for mass production. Many home sewing machines can be turned into an embroidery machine by adding a hardware module. Embroidery machines can be found in fab labs and other maker spaces.

Embroidery design software exists in various form, either as special-purpose tools for various design stages or as complete design suites. Embroidery designs can be stored in a multitude of proprietary design formats, that can be exported to proprietary machine formats (now often sold over the Internet). Free "open source" designs files are difficult to find. Converter software between various machine formats exists. Most design formats cannot be translated.

## History[edit | edit source]

It can be argued that computer-controlled embroidery machines are older than computers. In the beginning of the 19th century, Jacquard invented looms controlled by a "chain of cards". However, embroidery machines controlled in real-time by a "puncher" through pantographs dominated the market in the 19th century and lasted until the 1970's we believe. Models made between the two WWs used punched tapes for control, i.e. software driven embroidery machines became important. In the 1980 the first computer-controlled machines for the home market appeared (Wikipedia, retrieved May 2018). Chitter Chatter Embroidery Machine History and Ann the Gran Embroidery History include some interesting pictures.

According to Wikipedia and other sources, the first modern day computer controlled sewing machine was built by Orisol in 1987 for making shoes, i.e. much later than embroidery machines.

## Stitching and design steps[edit | edit source]

More or less according to Wikipedia, the basic steps for creating an embroidery are as follows:

* [Optional] Get or create a digitized embroidery design file in some kind of editable format. Typical formats are .emb, .exe, .dst, .cnd and .fdr. Each software manufacturer has its own proprietary format.
* [Optional] Combine it with other designs, e.g. add some custom lettering (optional)
* Translate the design to machine executable code (or get a file that is executable). Typical formats are .art, .pes, .jef, .sew and .hus (see below)
* Load this "stitch" file into the embroidery machine
* Stabilize and hoop the fabric and attach the hoop to the machine
* Start and monitor the embroidery machine, i.e. change the thread if needed.

Creating a digitized embroidery file itself includes at least two steps:

* (Optional) Create a drawing in an editable vector format. It is also possible to vectorize (traced) raster images, but this can be very time consuming.
* Digitize (translate, punch) the vector drawing to a (preferably) editable embroidery design format. A stitchable design includes embroidery-specific information like stitches and thread color. Good software rather defines "stitch objects", e.g. lines and fills (columns and areas) that are parameterized with stitching information such as the filling patterns, density, stitch density, pull compensation, stitch direction, etc..
* Export to machine-specific formats.

## Typical paradigm[edit | edit source]

While some more modern machines perform actions like dropping a sequin to be sewn in place, most modern embroidery consists is entirely of the same looped interlock stitch that have been the mainstay of sewing machines since their inception. Computerized embroidery formats ultimately contain instructions for the embroidery machine to perform. Move to a new location in two different directions, move but block the needle-bar (jump), cut the thread, drop the needle, switch to the next thread. These are all the actions that a sewing machine can take, usually in increments of 1/10th a millimeter. The goal then within design software is often how to pattern these stitches in useful ways for the person using the software. These patterns result in a lot of the underlying concepts within embroidery software. Stitches like zig-zag, satin, flat fill, bean stitch, and others are simply straight stitches in particular patterns, and the methods used to generate these are not explicit to the media.

Typically modern embroidery software uses vector shapes with fills applied to the objects. This allows the users for editing of the objects and thus the fills those objects create and adjustments to the density, direction, or any other property used to generate the resulting stitches. The advantages to this is that embroidery can be done quickly. A lot of stitches in recognizable patterns can be applied quickly with skilled users getting the results they expect. The software then stores the vector object and the fill properties to generate the underlying stitches. When the underlying stitches are edited by the user, regenerating the stitches would lose those modifications.

While vectors are a key aspect of this paradigm, it's not the case that you could go from vector to embroidery without some additional information about the type of fill being applied to that object. While software could take a vector as the answer of where to fill, they don't answer the question of how to fill. There's also a considerable amount of things that are technically permitted of a series of short line-segments (and thus embroidery) but are not easily accomplished through the dominant paradigm.

This seems to be the reason there are so many different formats, basically a different one for each type of embroidery. And different versions of formats add more such features to the software. If you wish to edit a design later, you need to have all the objects the file used to generate the stitches. Often software suites develop different methods for filling various objects or different features and these are unique to that particular brand. It's also the reason why, even when some formats have vector information (say PES files), these are not loaded by other software (eg. Wilcom Trusizer) in a manner that could be resized beyond about 10% without noticeable loss of coverage for the fill. Other software that can load a format, will often only load the actual stitches themselves (since that's what, all embroidery files must have to be sewn), which prevents any editing of the shapes used to generate them initially.

A straight stitch or running stitch is the typical name for a stitch that is generally not in the pattern of one of the other types of stitches. Technically all stitches are the same and they are all running stitches. They can't be anything else.

Fill stitches, also called tatami stitch are montone fills of particularly defined areas. These tend to be a sort of flood fill done with stitches. Most modern embroidery software executes this by using vector objects which then have a fill applied to them.

Mathematically the objects being filled must be monotone or broken into different parts. Monotone geometric objects can be filled with an unbroken scanline starting from the top to the bottom without changing directions. Since some objects being filled will lack this property, the objects are converted into monotone objects by clipping off the non-monotone parts. These are then underpathed (a straight stitch to the other merge/split node occurring such that it will be covered) and filled, and merged with the current fill. There is a lot of differences in how this algorithm is implemented between different software suites.

Sometimes even monotone objects are broken in this manner to allow for a start and stop location to be predefined. If you are filling a circle from the top to bottom, but want to start from the left, the algorithm will need to underpath to the top, then fill to the bottom. If an exit location is needed, it will stop at the level of the exit-node, underpath to the bottom, then fill up to the exit position.

Satin stitches are so-called because they have a soft satiny look. They are geometrically sweep fills of sweepable objects. A sweepable object is one that can be completely filled by a sweepline that transverses the object and is permitted to change directions. By definition if an object is sweepable it is monotone, as it does not need to change directions. Satin stitches are usually done with areas small enough that a single stitch can fill the objects.

This covers most of the conceptual design aspects within embroidery software. Some popular tools like Wilcom B, generally work by creating the vector object and fill direction and fill information at the same time. Which is a step away from the paradigm of vector + fill -> embroidery.

## Moving on[edit | edit source]

The concepts of computerized embroidery article will introduce some important practical concepts of machine embroidery. Embroidery stitch types are discussed in a separate piece. Hooping and stabilizing in computerized embroidery explain how to ready a fabric for embroidery.

Embroidery software tries to provide an overview of various embroidery software. Stitch Era tutorials is the starting point of a vector-drawing centric series of tutorials of a powerful and relatively cheap complete embroidery software. InkStitch is the start page of a tutorial series for an open-source platform based on Inkscape, the open source drawing program.

For technical people, software developers in particular, Embroidery format assembles everything that is known about propriety machine embroidery formats.
