While there are numerous suggestions for good machine embroidery designs , there are hardly ever any hard and fast regulations. There is no formula method for digitizing all designs; there are simply a lot of parameters involved. Rather, guidelines are balanced against the task at hand and the factors under which a unique design might be sewn. These needs to be regarded as you determine underlay requirements:

Underlay must serve a purpose

Underlay should be consistent

Underlay should be orderly

Underlay ought to be appropriate

The 2 primary purposes of underlay are to stabilize the fabric by attaching it for the stabilizer and assistance the top stitching. Think of underlay as a way to at first baste the fabric to the stabilizer. The easiest way to do that has been what is called an edge walk, which is simply an outline from the design set inside the edges of the cover stitching. On smaller things, it may well just be a line of running stitches up the center, referred to as a centre walk. On greater fields, this edge walk is followed by a light fill or zigzag as required by the fabric. In excessive cases, this light fill will be replaced using a mesh or grid of stitches. The reason is, underlay lowers fabric moving through the sewing process, and thus also lowering puckering. Appropriate choice and utilization of underlay decreases the push and pull distortion resulting from machine thread tensions. By attaching the fabric to an proper stabilizer, the fabric even very unstable one acquires the stability qualities of the backing used.

Don’t forget this there are other causes of fabric puckering that won’t be cured with underlay. These include; poor hooping strategies, poor or insufficient stabilizing choices, and tight machine tensions, especially when combined with polyester thread. Underlay supports the top stitching by maintaining a crisp, well defined edge between abutting areas of stitches. Underlay also avoids stitches from sinking in the fabric. Highly textured fabrics like terry cloth towels may benefit from a light net of underlay to keep down the nap and supply a smooth even surface for later stitches. Digitizers also make use of underlay creatively to provide additional loft to some sections of an embroidery designs to increase interest, depth, and realism.

CONSISTENT AND ORDERLY

Underlay should be utilized in a neat and tidy manner, which occurs automatically when used as an attribute option; it must not seem like haphazard scribbling. Consistency is not to mean that the same type or level of underlay should be applied to every object in your design.

APPROPRIATE

This one is complicated and is realized mainly from expertise and assessment. Selecting the best combination of underlay is relative to: Fabric type, color, and stability; Design size, stitch count, density; Desired effect. Smooth, hard, stable fabrics like nylon, supplex, cordura, and some polyester blends may demand simply an edge walk. Leather, vinyl, paper, and metal really need no underlay normally in order to avoid unintentional cutwork. Uneven fabrics and unstable items will demand more underlay. Now you can see why there’s not “cookie cutter” procedure for underlay

As the design size gets larger, stitch count rises and the prospect fabric distortion raises. Just utilizing a larger hoop reduces the soundness of the fabric. A design with large areas of fills, in particular if these fills run in several directions, radically increases the probabilities for fabric push and pull. Underlay may help control design distortion, but remember additional circumstances that impact distortion: Proper embroidery set up – stabilizer selection, fabric, thread, and needle options; hooping approach; machine tensions; Proper utilization of density; Proper utilization of compensation. Creative utilization of underlay can dramatically change a design. In case a satin or fill area is sewn over an area of stitches with both areas having the same stitch direction, the top stitches will fall into the previous layer. This is often a good thing if you want blending together or perhaps a bad thing if you would like sharply delineated items. Adding underlay prevents blending. Smartly placed and extra underlay adds loft to satin stitches. A good digitizer leverages underlay to his or her benefit

here are some of issues digitizers look at when using underlay.

Color-Underlay, like under garment, mustn’t be visible, so you have to use the same color as the covering stitches. When utilizing the auto underlay configurations, you won’t even have to consider this. If an initial global underlay is used, consider setting it as another color so that it may be sewn in color that matches the fabric. Stitch Length Work with a moderate stitch length to stop the looping of longer stitches and to keep the stitch count more reasonable than would result with short stitches. Use shorter stitches only as needed to prevent exposure problems.

Density-Just use enough density to meet the requirements of the job.Placement-Underlay must not reveal or bleed through to the covering embroidery design . Make certain underlay never runs within the same direction as the top stitches. Seriously consider placement and uniformity in small objects, especially tiny letters.

Amount-Use underlay judiciously when and where needed; don’t use it in excess, which can unnecessarily run up stitch counts. Not enough underlay, alternatively, can result in bad registration, fabric puckering, “fuzzy” or jagged edges on objects, and fabric show-through. At minimum, use enough underlay to securely and smoothly tack backing to fabric when working together with wovens and knits.
