CMYK is the correct answer because it stands for cyan, magenta, yellow, and key (black), which are the four process colors used in printing. This color mode is specifically designed for printing purposes, where different combinations of these colors are used to create a wide range of hues and shades. RGB, Index, Grayscale, and Black and White are not the correct answers as they do not represent the four process colors used in printing.

Bleed refers to the printing technique where the ink extends beyond the edge of the paper after trimming. This is done to ensure that there are no white borders or gaps around the printed material. Bleed is commonly used in design projects such as brochures, flyers, and business cards to create a professional and polished look. By allowing the ink to extend past the trim lines, it ensures that there are no inconsistencies or imperfections in the final printed piece.

Color separation is the technique of using a camera, scanner, or computer to divide continuous-tone color images into four halftone negatives. This process separates the image into four separate colors (cyan, magenta, yellow, and black) which are then printed using these four colors to create a full-color image. Color separation is an essential step in the printing process as it allows for accurate reproduction of colors in the final printed piece.

Overprint refers to the process of printing one image on top of another image that has already been printed. It is commonly used to print type or other elements over a screen tint. This technique allows for the combination of different colors and layers, creating a desired effect or enhancing the visual appearance of the printed material. Overprinting is also known as surprint and is a common practice in the printing industry.

A press check is an event where makeready sheets from the press are examined before authorizing full production to begin. This is done to ensure that the printing press is set up correctly and that the colors, registration, and overall quality of the printed materials meet the desired standards. It allows for any necessary adjustments or corrections to be made before running the full production, thus minimizing the risk of errors or defects in the final printed products.

A digital proof refers to the process of producing page proofs through electronic memory and transferring them onto paper using laser or ink-jet technology. This method allows for accurate representation of the final printed product before it goes into mass production. It eliminates the need for traditional methods like contract proof or press proof, and also does not involve die sublimation or xerographic printing.

Knockout is the correct answer because it refers to the process of eliminating or "knocking out" a portion of an image or design, allowing the background to show through. This can be done by using a special printing technique or by adjusting the transparency of the image digitally. By knocking out certain areas, the image can be masked or blended seamlessly with the background, creating a desired effect or allowing for layering of different elements in a design.

A duotone is a black-and-white photograph that is reproduced using two halftone negatives, each shot to emphasize different tonal values in the original. This technique adds depth and visual interest to the image by using two different ink colors. The use of two tones creates a unique and artistic effect, making the image more visually appealing compared to a simple black-and-white or grayscale photograph.

Trapping is the correct answer because it refers to the process of overlapping one color over another to prevent any white space from showing where the two colors meet. This is particularly important when there are slight variations in the registration of the two colors during the printing process. Trapping can involve printing wet ink over wet or dry previously printed ink to ensure a seamless and visually appealing result.

Prepress refers to the various tasks and processes performed by the printer, separator, graphic artist, or a service bureau before printing. These tasks include camera work, color separations, stripping, platemaking, and other preparations necessary to ensure the quality and accuracy of the final printed product. Prepress is an essential step in the printing process as it ensures that all elements are properly prepared and ready for printing.
