In some printing processes that use spots color, like screen printing, you need to isolate each color into individual color areas so they can be printed on the same plate or screen. This is called a separation.

When printing screen-printed separations, you can add your own custom registration marks on the page so you can control where they are on the output. If you use the registration color for these marks it will show up on each separation without having to change the color. This color is good for job names and registration marks to keep them consistent on all films or screens. You can drag this color to the document palette or a custom palette for easy access.
Sometimes screen-printed separations need trapping or a base color for printing. You can use another page for these modified versions of the artwork. For example, page 2 in the exercise file has the base white separation. For the white ink base, you would print it from this page. For extra organization in your file, you can label the page the color being printed by right-clicking on the name of the page.
Spot color separation in Photoshop can be done a couple different ways. One way is to separate each color to it's own layer in Photoshop and print your film positives. This is a very simple and "crude" way to create your film positives for screen printing. But hey- when your in a pinch it can work so you can get the job done. When you use this method just make sure to lay black color over the layer be fore you print each layer as a "separation".
Screen printing is an old technique that has stood the test of time. As one of the most popular methods for printing onto t-shirts, screen printing can produce durable and long-lasting results. However, a labor-intensive initial setup means screen printing is most cost-effective when printing in bulk. Screen printing also poses issues when it comes to complex designs or designs with more than four to five colors as each color increases costs and production time.
Direct-to-garment printing produces quality printing on par with screen printing and better than heat transfers. Because it operates just like an ink-jet printer, there are no setup costs, unlike screen printing. This means that it's easy and cost-effective to print small orders.
In the early 1950s, several companies based in Miami, Florida, started to decorate T-shirts with different resort names and various characters. The first company was Tropix Togs, under founder Sam Kantor, in Miami. They were the original licensee for Walt Disney characters in 1976 including Mickey Mouse and Davy Crockett. Later, other companies expanded into the T-shirt printing business, including Sherry Manufacturing Company, also based in Miami. Sherry was founded in 1948 by its owner and founder Quentin H. Sandler as a screen printer of Souvenir Scarf's to the souvenir resort market. Shortly, the company evolved into one of the largest screen printed resort and licensed apparel companies in the United States. The company now (2018) runs automatic Screen Print presses and produces up to 10,000 to 20,000 T-shirts each day.
In the 1960s, the ringer T-shirt appeared and became a staple fashion for youth and rock-n-rollers. The decade also saw the emergence of tie-dyeing and screen-printing on the basic T-shirt and the T-shirt became a medium for wearable art, commercial advertising, souvenir messages, and protest art messages. Psychedelic art poster designer Warren Dayton pioneered several political, protest, and pop-culture art printed large and in color on T-shirts featuring images of Cesar Chavez, political cartoons, and other cultural icons in an article in the Los Angeles Times magazine in late 1969 (ironically, the clothing company quickly cancelled the experimental line, fearing there would not be a market). In the late 1960s, Richard Ellman, Robert Tree, Bill Kelly, and Stanley Mouse set up the Monster Company in Mill Valley, California, to produce fine art designs expressly for T-shirts. Monster T-shirts often feature emblems and motifs associated with the Grateful Dead and marijuana culture.[16] Additionally, one of the most popular symbols to emerge from the political turmoil of the 1960s were T-shirts bearing the face of Marxist revolutionary Che Guevara.[17]
The most common form of commercial T-shirt decoration is screen printing. In screen printing, a design is separated into individual colors. Plastisol or water based inks are applied to the shirt through mesh screens which limits the areas where ink is deposited. In most commercial T-shirt printing, the specific colors in the design are used. To achieve a wider color spectrum with a limited number of colors, process printing (using only cyan, magenta, yellow and black ink) or simulated process (using only white, black, red, green, blue, and gold ink) is effective. Process printing is best suited for light colored shirts.[22] The simulated process is best suited for dark colored shirts.
Dye-sublimation printing is a direct-to-garment digital printing technology using full color artwork to transfer images to polyester and polymer-coated substrate based T-shirts. Dye-sublimation (also commonly referred to as all-over printing) came into widespread use in the 21st century, enabling some designs previously impossible. Printing with unlimited colors using large CMYK printers with special paper and ink is possible, unlike screen printing which requires screens for each color of the design. All-over print T-shirts have solved the problem with color fading and the vibrancy is higher than most standard printing methods but requires synthetic fabrics for the ink to take hold. The key feature of dye-sublimated clothing is that the design is not printed on top of the garment, but permanently dyed into the threads of the shirt, ensuring that it will never fade.
Other methods of decorating shirts include using paints, markers, fabric transfer crayons, dyes and spray paint. Some techniques that can be used include sponging, stenciling, daubing, stamping, screen printing, bleaching, and many more.[25] Some new T-shirt creators have used designs with multiple advanced techniques, which includes using glow-in-the-dark inks, heat-sensitive fabrics, foil printing and all-over printing. Other designers like Robert Geller, a German-born American fashion designer, has created a T-shirt collection which feature oversized graphic T-shirts made from super soft jersey materials. Alexander Wang came out[clarification needed] with variations of T-shirts from oversized scoop necks, tanks to striped, slouchy rayon jerseys.[26] Terence Koh T-shirts feature an upside down portrait with a real bullet hole hand.[27]
Screen printing is an analogue method of fabric printing. Screen printing involves pressing the paint through a printing screen (made of a steel frame and a nylon mesh) and thus making a print. This operation can be performed manually (the paint is then squeezed manually through the screen) or with a machine (the paint is automatically pressed by the machine through the screen).
So when should you opt for screen printing? For example, when you want to print 1000 linear metres of black material with white dots. To carry out a project with such an uncomplicated design, the method of screen printing will be ideal. Currently, there is no better method available on the market for printing such graphics on fabric. The basis may be a black-coloured fabric on which white dots are applied with a single screen. Therefore, the conditions to be met are a large volume (which cancels out the cost of preparation of the printing screens), undemanding patterns and the necessity of putting colour on a very dark background.
One of the easiest ways to save a screenshot taken with the print screen key is to paste it into your photo editing software of choice. For example, you can use Microsoft Paint, which comes free with all relevant versions of Windows. 2ff7e9595c
