A conventional machine changes color by switching needles, so a design is planned as solid blocks of thread with trims and color stops between them. A Coloreel unit colors a single white thread as it feeds the needle, so color can shift gradually along one continuous run of stitches.
To use that, the stitch file and the color file have to be planned together. We build the stitch file, color it in Coloreel Studio, set the color transitions within the CCP (Color Change Precision) tolerance and review the preview before delivery.
A file digitized for a multi-needle machine can still be colored in Coloreel Studio, but its stitch paths were laid out for solid blocks, so blends tend to break where the paths do. If you run the same logo on standard machines too, keep a conventional multi-color embroidery file alongside it, or have us build a flat-color version of your brand logo.
Gradients read best on big areas. Lettering under about 0.2 in stays in flat color, because a blend across a letter that small is not visible and only costs legibility.
