Queries: How do you get such gorgeous colors in your fabric banners?
Answer: Our polyester fabric banners are printed using the heat transfer or dye sublimation printing strategy. This process uses heat and stress to create almost photographic reproduction of your pictures on fabrics from knits to satins to sheer fabrics.
The way the dye sublimation printing approach functions with fabric is this. Initial, the dye, which is slightly diverse than ink, in that is certainly CMYO (cyan-magenta-yellow-overprint) as an alternative to CMYK (cyan-magenta-yellow-black), which can be the standard colour palette for digital and screen printing, is printed directly to a transfer paper.
When the paper is printed, it is actually married to a piece of polyester fabric. Why polyester? Polyester can be a synthetic oil-based fabric, so its cellular structure is closed, in contrast to cotton or silk, which can't be dye sublimation printed, a minimum of not at this writing. When heated, the cells open. This can be significant when the fabric and paper are sent by means of the heated rollers at about 400oF.
Because the paper and fabric go through the heated rollers, the cells in the poly fabric open to accept the dye, which is converted to a gaseous state as a result of heated rollers. That is exactly where the term dye sublimation comes from. The dye is sublimated into the cellular structure in the polyester and really becomes portion from the fabric, which can be why the colors are so durable and also why we get those gorgeous colors, like a photograph. This color is known as continuous tone printing, since it does not depend on dots of color like digital printing does.
Query: What is the distinction among grommets and pole pockets?
Answer: There are lots of ways to hang banners, and those are two of your most common techniques, with velcro getting a 3rd way, even though you have to have hook velcro on a wall or object to attach the loop velcro to.
Primarily, grommets are either metal or plastic rings that come in two components, named the grommet and the washer. 1st, your material needs to become much less thick by at the least 1/16" than the depth with the grommet. A hole is punched within the material, say a vinyl banner, as well as the grommet is inserted by means of the bottom, then set in to the bottom setting die. The washer is placed over the throat of the grommet, then, if this can be the simplest approach, a hammer is used around the top setting punch tool plus the grommet is set. Other solutions are the manual grommet setter and also the pneumatic grommeting machines which might be fed manually, or in bigger plants could be fed with components automatically.
A pole pocket is easier to describe, and is favored by some for hanging banners, especially indoors. Grommets are a lot more prevalent out of doors exactly where banners are hung involving light poles or trees or pinned for the side of buildings with concrete anchor pins or the like. Indoors, banners usually be smaller which favors pole pockets to a degree. When a banner is printed, it's hemmed having a fabric loop on the top and from time to time the bottom, and less often the sides (unless it can be a retail display or possibly a trade show display or backdrop). A pole is often inserted by way of this pocket, and some variety of hanging apparatus connected to every single end and hung in the ceiling.
While you did not ask, I'll also talk about velcro. Velcro comes using a loop element and a hook component. It comes either with adhesive backing or not, depending if it is being sewn to some thing like a banner. The adhesive side will probably be attached to frames or the like, and a banner with velcro sewn to it will be attached speedily and simply.
