It burns quickly, captures fine detail, lasts against aggressive inks, reclaims painlessly, and is forgiving. Printers working in a less-than-ideal darkroom environment learning the craft and printing with plastisol, water-based, or discharge inks should take a look at Baselayr Long Lasting Emulsion.
Coated screens with little to no moisture will lead to proper exposure, resulting in the best detail resolution in the stencil.Coated screens with moisture will lead to under-exposure, making it difficult to rinse out the image.Yellow mesh=longer exposure time (produces more detail resolution).The following factors are what printers should consider when selecting exposure times: Luckily, there are guidelines that can help decipher exposure times. Stencil thickness, mesh color, mesh count, the moisture content in the screen, quality of exposure unit, etc. Not only does a printer need to learn the nuances of the new supply and how it works with their tools in their environment, but they also need to see how other factors may affect the end result. When implementing a new tool or supply, printers need to test it out before running production. If a printer tries something new, test before running production. In the end, coating techniques drill down to the type of ink a printer is using, the design needs, and what works best for production. For mesh counts higher than 230, 1x1 or 2x1 coats are a better choice. For mesh counts below 230, a 1x2 or 2x2 coat works. When printing thicker inks like plastisol ink, the mesh count will also factor into the coating strategy. Thinner inks like water-based ink need either a 1x1 (one coat on the t-shirt side of the screen, one coat on the squeegee side) coat or a 2x1 coat.
Emulsion for screen printing how to#
The type of ink will determine how to coat a screen. RELATED: 4 FACTORS TO KEEP IN MIND WHEN SELECTING EMULSION If a printer is working in a darkroom that isn’t life-safe, using an exposure unit with a weak light source or learning how to coat and burn screens, Baselayr Long Lasting is the best emulsion to help achieve great results. One of the best features of Baselayr Long Lasting Emulsion is its forgiveness. No matter the ink the printer is using, the stencil will hold all details throughout production. It’s a durable emulsion that stands throughout water-based or discharge ink runs. If exposed correctly, the stencil rinses out quickly, and reclaiming is painless. It’s easier to expose and faster to burn compared to other diazo-mixed emulsions. To learn more about why a screen printer would use this emulsion, the inks it can handle, coating tips, and dialing in exposure times, continue reading.īaselayr Long Lasting is a high-quality, high solids emulsion. One of those options is Baselayr Long Lasting Emulsion. With three options, Baselayr makes emulsion simple. Photo Emulsion (used with the accompanying Diazo Sensitizer) is a light-sensitive emulsion used to burn stencils directly into a silk screen for photo imaging. The screen printing market is saturated with all kinds of emulsions. To get a solid stencil, printers need to use a high-quality emulsion.
