Screen-printing, or serigraph, previously known as Silk screening is a printmaking technique that traditionally creates a sharp-edged image using a stencil and a porous fabric. A screen-print or serigraph is an image created using this technique. It is related to resist dyeing on cloth. It began as an industrial technology, and was adopted by American graphic artists in the 1930s; the Pop Art movement of the 1960s further popularized the technique. Many of Andy Warhol's most famous works, including his Campbell's Soup Cans, were created using the technique. It is currently popular both in fine arts and in commercial printing, where it is commonly used to put images on T-shirts, hats, ceramics, glass, polyethylene, polypropylene, paper, metals, and wood.
Spot color printing uses distinct ink colors. Our presses allow us to use from one to six colors on a design. The image above is a six color using black,green, brown, red, purple and gray, with some additional half-tone shading in the black. We are capable of producing shirts using any Pantone color you may choose. There is a charge for ink mixing, however, and we do offer about 40 different colors without further charge. The ink colors are solid on the surface of the shirt, without color variations, although shading is often achieved through the use of screen half-tones. Artwork, again, comes to us in many forms. Hard copy requires a separate piece of artwork for each color, typically on paper or artboard. If you need us to, we can separate the colors for you. Digital copy is best provided in an Illustrator file although EPS is an acceptable alternative. Acceptable by either disk or email, we do again request that, if possible, you stuff your file before emailing it to us. If you are sending an Illustrator file, all fonts should be converted to outlines.
To reproduce full-color photographic images, typical printing presses use 4 colors of ink. The four inks are placed on the paper in layers of dots that combine to create the illusion of many more colors.
In the past, 4-color process would be the best solution for screen printing on a white garment. Many people still like the results 4-color process printing provides. The advantage that simulated process offers is a much brighter more colorful image because the design is printed with solid opaque colors. When printing 4-color process you are re-creating all of the colors in the design by mixing Cyan, Magenta, Yellow and Black ink. This form of printing was originally designed to be used in the area of offset printing (i.e.. Brochures, magazines, etc.) If quality is what your after, simulated separations apply a much brighter and cleaner image when printed.
The term "discharge" refers to a chemical reaction that destroys the ability of certain dyes to reflect a color. In simple terms, the discharge agent in the ink breaks down or bleaches the dye out of a specially prepared garment, leaving white, undyed fabric in the print area. When printed, discharge inks are almost transparent on the garment, activating only during the curing process.
