Much like a dye process water-based and water-based discharge are water born systems where the print ink is absorbed into the fabric. This creates a softer, longer lasting and more environmentally friendly screen printing process. Although there are some poly blended fabrics that are compatible with water-based printing it's recommended that only 100% cotton garments be used with this process. In some situations brighter fabric colors such as purple, royal and kelly green are not compatible with light on dark printing because they do not fully discharge.
A PVC or acrylic and liquid plasticizer ink system plastisol creates a durable surface film on the fabric. Although not as soft as water-based printing plastisol is far more versatile and when used intelligently can create a variety of desired effects. 4 color process, simulated process and metallic are all based on the plastisol ink system. We take care to minimize our footprint on the environment by using phthalates and PVC free inks when possible.
A plastisol additive that allows inks to adhere to waterproof nylon materials such as jackets and bags. Keep in mind that the temperatures needed to cure plastisol can often exceed the heat exposure recommended for treated synthetic materials, this results in having to flash cure some prints that use nylabond.
4 Color Process
With semi transparent plastisol inks four color process uses halftones of CMYK to create a photo realistic print process. As a subtractive color system CMYK must be printed over a white substrate. Although white garments are ideal colored garments are compatible with this system when a white baseplate is printed under the graphic silhouette.
Much like 4 color process simulated process uses halftones to represent varied shades of a print color. However unlike 4 color process it uses solid opaque inks making it more compatible with darker garment colors.
Available in an array of colors metallics are plastisol based inks with reflective particles that create a chrome or gold like finish. Because these inks generally have a high viscosity a low mesh screen is required to print them making for a thicker ink deposit.
A plastisol ink that uses phosphorus to store surrounding light and then illuminates it in the dark. This ink is generally transparent and can be overprinted on other print colors. It glows a light green.
Fabrics that contain high amounts of synthetic fibers releases their dye when heated causing dye migration between the garment and the screen printing ink. Specially formulated poly inks are required to preserve the intended print color.
