In this blog we will look at preparing the fabric for your designs, and understanding why you should use a particular type of underlay in building a foundation for the machine embroidery design. Underlay Types There are many names for the basic types of underlay in Pulse products you have several types, including Contour, Parallel , Perpendicular, Zig Zag, Lattice , Full Lattice and Center run. Contour Underlay When no underlay is applied, the thread making up the satin column lays flat on the fabric. This not only makes the embroidery look flat, but it allows the grain or nap of the fabric to peek through. Many new designers would increase density to block out the fabric peeking through, but it would be more effective to apply the proper underlay. Tip set the contour to .02 inches on the inset to make sure it doesn't stick out on corners. Never use by itself on a fill. Parallel Underlay My favorite for text , I use the parallel underlay on any column stitch or steil stitch when ever possible, I find it gives the columns a good foundation prior to the stitching, its like a zig zag stitch but not as dense. I use it on knits and many of the stretchy type materials, including golf shirts, t-shirts, sweats, and hats and knitted caps. Perpendicular Underlay The perpendicular underlay puts a column of lines down the center of the column and is often with each line just off center. I have used this with towels when I want to raise the text up a bit in addition to using zig zag. Advantages of this it will help push the column apart as the stitching goes in opposite direction of the satin stitch. Zig Zag Underlay Zig zag underlay provides additional loft than what can be achieved by Perpendicular or Contour. These two underlay types are especially effective at lifting the top stitches on fabrics such as pique, terry cloth and fleece. Due to their lofting characteristics, they are also used to give life to design aspects such as leaves or muscle tone to animals. Zigzag underlay is often used in addition to center run underlay where the center run is securing the fabric and the zigzag is creating the loft. This combination is the most under-used of the underlays, but when used at the appropriate time can set your design apart from others. Best used on satin stitches, Lattice Underlay It can best be described as a light density fill, normally running perpendicular to the top stitch. The fill underlay anchors the target fabric to the backing and is the best way to reduce the push and pull factor so common to fill areas. It also lifts the top stitches up and allows a much less dense fill to be applied. This is the best way to prevent your designs from suffering from "bullet proof" fill areas. First placing a Contour underlay and then a lattice underlay has proven to be the best combination for medium to large fill areas. Center Run ( New Version 14 only) In version 14 there is a new underlay option called center run it places a stitch right in the center of the column. This is very useful on small text as it helps keep it conformed to the space provided, and doesn't usually cause to much bulk for theses small letters. Automatic Underlay Automatic underlay can be applied with a recipe or style when using the software or you can apply it by going to properties and adding the type of underlay you want. You can also adjust the inset, density, the stitch length and angle of the stitches, number of lines, drop stitch or angle of the underlay. It can be very useful. Manual Underlay I use manual underlay when working with fills that have steil borders and or when the garment has a lot of stretch too it. Typically Automatic underlay goes under each segment, however there are times when you want the underlay to go under both segments all at once. This will eliminate the two parts pull apart, the easiest way to make this is to use the complex fill tool draw a shape around all the segments and cover them completely, see comparison below; Above you will see both the manual and the automatic have both a lattice and a parallel underlay applied, the Automatic the two underlays do not overlap where as the manual you can place the underlay underneath the parallel which will prevent the two from separating. I use this method quite a bit when digitizing. Terminology for Underlay Settings Angle The angle of the underlay Connection End The type of end used , option include, Sharp, Square Chiseled and Zig Zag. You can change the connection end to adjust either the appearance or how the design sews out. Density The density of the underlay how thick the underlay stitches will be, normally around 10.5 spi Drop run stitch Is a setting to ensure the proper placement of the run stitches, setting include None, At Anchor, Chord gap. At Anchor Drops the run stitch and penetrates it at the anchor points - None forces the run to stitches to follow the stitch length - Chord Gap places the stitches fit to the top portion of the curve smoothly by shortening stitches at the top of the curve Inset The distance the underlay stitches are placed from the edge of the top stitching. Inset A The outside inset Inset B The inside inset Max Chord gap The Max Chord Gap is the maximum gap between two points on a bezier curve. Min Stitch length The minimum stitch is usually set to .02 normally you do not want to go under this however sometimes you want this stitch higher. Override Some setting in the underlay they use a particular pattern, there are times when this is not suited for the application Repeats This is a setting when you want the underlay to repeat Sometimes it better to go over the same spot Sequence The sewing order of which underlay goes down first sometimes you want a perpendicular to go down before doing a parallel stitch to give some extra support. Stitch Length The length of each stitch on the underlay, the shorter is ideal when working with smaller sizes, but does increase the stitch count Application Notes 3D Foam When applying underlay to use with foam you have to remember that you do not want to suppress the foam, if you feel the need to add underlay use a contour underlay with a short stitch length. Make sure the design is made for puff. Leather With leather you do not want the underlay to punch a hole where the designs is going to go through this can cause the material to rip , With leather reduce the density of the underlay, and rotate the underlay to a 45 deg of the top stitch pattern. Small Lettering I recommend using either the center walk on small letters or punching the underlay manually, watch the stitch lengths, and use a smaller needle and thread. Large Lettering I using parallel or a lattice to compensate for the amount of stitches going down, recommend cutaway to support large letters in large hoops.

hi there, is there a standard density satin stitched lettering should have when going over the top of a complex fill stitch? when i do say 5-6mm lettering on top of a complex fill, i usually have the density at -.5 to -.6, with the pull comp at approx .12 to .15 - it normally comes out looking great, except where the stain stitch letters have the same angle as the complex fill, causing the lettering to fall away and get lost in the complex fill.making these letters look thinner than the rest. and should there be an underlay on small text when going onto of a complex fill stitch?? i normally use a single line underlay stitch at approx length of 1. to 1.5. can anyone out there help, this is lettering our digitizing and quality down your help would be greatly appreciated thanks

Hi there, i have been digitizing for awhile now and sometimes i notice when i have digitized a rectangle or square complex fill with either a 45 or 315 degree angle stitch, it sews out crooked. does anyone out there know why this is?? the fabric? the underlay? the density? its getting quite frustrating as the rest of the design will look fantastic but the simple block behind the logo just lets the overall look of the logo down.any help would be hugley appreciated, thanks

Hi guys, Is anybody else having this issue? I'm working on a design and I go to add underlay and all of the fill stitching disappears. I tried resizing the embroidery design and everywhere I had done shading all of the fill underneath disappeared. This just started today. I did another design with some of the same features 2 days ago, and it worked just fine. I thought perhaps I was missing a release update, so I checked and yes, I was one behind and ran that, but the problem still exists! HELP!!!!!!

What type underlay stitch you use? Whether you use a manual method of laying machine embroidery stitches.In Printwear I read an article about the ability to make some digitizers using manual non-standard methods. Question how is it necessary? This requires more time, ie, the order will cost more.
