Read the first 7 Print Production & Prepress flashcards as text

  1. In prepress production, what is the primary purpose of 'trapping'?

    Answer: To prevent white gaps at color boundaries caused by misregistration on press

    Trapping adds slight overlaps between adjacent colors so that minor press misregistration does not create visible white gaps between color areas.

  2. What does a Raster Image Processor (RIP) do in a print production workflow?

    Answer: Converts vector and image data into raster dot patterns for output devices

    A RIP interprets page description languages (PostScript, PDF) and converts all content into the raster dot patterns that imagesetters, platesetters, and digital presses can reproduce.

  3. In offset lithography, what is 'dot gain'?

    Answer: The spreading of ink dots on the substrate that makes halftone dots appear larger than designed

    Dot gain occurs when ink spreads as it transfers from plate to blanket to paper, causing halftone dots to physically enlarge and making prints appear darker than intended.

  4. What is the typical total ink limit (TIL) for coated paper in CMYK offset printing?

    Answer: 320–340%

    Coated stock can accept roughly 320–340% total ink coverage; exceeding this risks slow drying, setoff, and paper damage even though four channels theoretically allow 400%.

  5. What is 'overprinting' in prepress, as opposed to a knockout?

    Answer: Printing one ink layer directly on top of another without removing the underlying color

    Overprinting allows an ink (commonly black text) to print over a background color rather than cutting a white hole (knockout), preventing gaps if registration shifts slightly.

  6. What is the standard bleed dimension used in US commercial print production?

    Answer: 0.125 inches (1/8 inch) beyond the trim edge

    US commercial printing uses a 0.125-inch (1/8-inch) bleed so that background colors and images extend past the trim line, preventing white slivers after cutting.

  7. Which file format is the industry standard for delivering print-ready files to a commercial printer?

    Answer: PDF/X

    PDF/X is an ISO-standardized subset of PDF created specifically for reliable prepress exchange, enforcing embedded fonts, appropriate color spaces, and no missing elements.
