1)Screen printing is silk screening modernized. Screen printing is fundamentally the same as what is commonly known as silk screening: a printing technique which uses a fine mesh or screen that is tightly stretched around a frame. The design to be imprinted is stenciled and placed on the screen. The screen is then placed on the item, ink on the screen and a squeegee (rubber blade) is used to press the ink through the screen. The ink is then dried and the same process is repeated with a different screen in cases of multiple color imprints. Through the years this method has been modernized. Additional techniques have been added to speed up the process and to improve the quality of imprint. [not clear how it is different than silk screening. What has been modernized compared to silk screening?]

2) In spot color printing, the imprint charges are based on the number of colors used. Spot color printing is a process of screen printing using solid ink colors and half tones. Costs are cheaper when printing one color than multiple colors. Matching the color to specific PMS colors is optional and you will incur an additional charge per color.

3) Printing a picture on an item is possible. This technique, called four-color process, is a digital printing technique where a colored image is separated into four colors:cyan (blue), magenta (red), yellow and key (black) or popularly known as CMYK. Once the colors of the image are filtered and separated, they will be transferred to imprinting plates. The plates will then be used to print the four colors in such a way that they reproduce the original image on the item. However, a four-color process can only be used for white and light-colored items, unless an underbase is used. [ is this what you mean to say?]

4) An ?underbase? is necessary when printing on dark items. Printing a light color directly onto a dark-colored item will change the appearance of that color. For example, printing yellow on a light blue shirt will result in a greenish color. To avoid this problem and have colors appear as expected, a white underbase is needed when printing on dark items., hence an underbase is required to print the correct color). The underbase is counted as one color and will incur an additional charge.

5) Screens are not stored for future use. After an order is completed, he screens are discarded. Reorders with the same imprint will incur the same fee again. Thus, it is better to place an order in bulk for all your expected future volume to avoid repeated screen charges of the same design.
