1. Prepress<\/h4>
  1. Show-through White\/Exposure White<\/strong>: When the paper used for printing is red and an area doesn\u2019t get fully printed, exposing the white paper underneath.<\/li>\n\n
  2. Flashing<\/strong>: In the era of halftone screens, a technique to enhance shadow details in a photograph during plate-making by flashing the original artwork or using a flash lamp to soften the image.<\/li>\n\n
  3. Overweight (Dot Gain)<\/strong>: Similar to gaining weight, the light-sensitive particles in film can expand, causing thicker lines. Manually, transparent layers could be added during exposure to increase thickness.<\/li>\n\n
  4. Trapping<\/strong>: Deliberately extending colors at the edges during color separation to compensate for misregistration in printing.<\/li>\n\n
  5. Solid Color<\/strong>: Refers to areas of color without halftone dots, typically full coverage.<\/li>\n\n
  6. Reverse Text<\/strong>: Text or lines printed in negative space, with the background printed and the text left as the color of the paper.<\/li>\n\n
  7. Moire Pattern<\/strong>: When halftone screens overlap incorrectly or angles are too close, it creates a visible moire pattern.<\/li>\n\n
  8. Ghost Screen<\/strong>: A technique in plate-making to reduce contrast by adding a screen after the main exposure.<\/li>\n\n
  9. Jagged Edges<\/strong>: Insufficient resolution in images causes pixelated, jagged edges when enlarged.<\/li>\n\n
  10. Rosette Pattern<\/strong>: A visual pattern created by correctly aligned halftone dots. Poor versions create “seat cushion” or moire effects.<\/li>\n\n
  11. Flush Left<\/strong>: Text aligned at the left edge of a column. This term can extend to layout and binding for alignment.<\/li>\n\n
  12. Ragged Right<\/strong>: A text alignment style where the right side is uneven, but spacing between words is consistent.<\/li>\n\n
  13. Masking Film<\/strong>: A tool used in manual color separation to block areas or modify colors.<\/li>\n\n
  14. Blue Plate<\/strong>: Not related to basketball or RGB’s blue; it refers to the cyan (C) plate in CMYK.<\/li><\/ol>

    2. Printing<\/h4>
    1. Ghosting<\/strong>: Unintended shadows or marks on prints, often caused by uneven ink distribution.<\/li>\n\n
    2. Low-Foot Lead Type<\/strong>: In the era of letterpress printing, lower-height type pieces were used for certain layout adjustments.<\/li>\n\n
    3. Sheet-Reversal Printing<\/strong>: A technique where sheets are flipped after one side is printed, allowing printing on the reverse side using the same plate setup.<\/li>\n\n
    4. Fly Ink<\/strong>: Ink splattering caused by excessive press speed or low ink viscosity.<\/li>\n\n
    5. Ink Line<\/strong>: A registration mark used to ensure proper positioning during printing.<\/li>\n\n
    6. Scumming<\/strong>: When the non-image areas of a plate do not repel ink properly, causing light ink deposits.<\/li>\n\n
    7. Cylinder Release<\/strong>: The separation of the impression cylinder from the blanket cylinder.<\/li>\n\n
    8. Jam<\/strong>: When too many sheets are fed into the press, causing it to stop.<\/li>\n\n
    9. Misfeed Stop<\/strong>: When paper is improperly fed into the press, triggering a stop.<\/li>\n\n
    10. Positioning<\/strong>: Ensuring the paper is aligned correctly for multi-color printing and cutting.<\/li>\n\n
    11. Pressing Through<\/strong>: When excessive ink thickness prevents the print from drying properly, leading to smudges on subsequent sheets.<\/li>\n\n
    12. Speed<\/strong>: The rate at which a press operates.<\/li>\n\n
    13. Assist<\/strong>: Refers to the press assistant or second operator.<\/li>\n\n
    14. Proof<\/strong>: A preliminary print used to check colors and layout before the final print.<\/li>\n\n
    15. Delivery<\/strong>: The system that transports sheets through the press.<\/li><\/ol>

      3. Binding<\/h4>
      1. Bleed<\/strong>: The area of an image or color that extends beyond the trim line, typically by 3mm, to ensure the design covers the entire page after cutting.<\/li>\n\n
      2. Trim<\/strong>: The process of cutting off excess paper, including the bleed area.<\/li>\n\n
      3. Crooked<\/strong>: Misaligned trimming can cause books to have uneven edges.<\/li>\n\n
      4. Gloss<\/strong>: A finishing process that smooths and enhances the surface of printed materials.<\/li>\n\n
      5. Manual Fold<\/strong>: Folding pages by hand in certain formats, such as a 32-page booklet with specific folds.<\/li>\n\n
      6. Signature<\/strong>: A group of pages printed on a single sheet, which are then folded and cut to create sections of a book.<\/li>\n\n
      7. Guillotine<\/strong>: The machine used to cut printed sheets into individual pages.<\/li>\n\n
      8. Saddle Stitching<\/strong>: A common binding method for thin booklets, where pages are folded and stapled along the spine.<\/li>\n\n
      9. Accordion Fold<\/strong>: A folding style where pages are folded in a zigzag pattern, like an accordion.<\/li>\n\n
      10. Reverse Cover<\/strong>: When attaching a cover, the back cover is affixed first, followed by the spine and front cover.<\/li>\n\n
      11. Book Block<\/strong>: The pages of a book that have been sewn together but not yet trimmed or covered.<\/li>\n\n
      12. Headband<\/strong>: A strip of cloth used to reinforce the spine of a hardcover book.<\/li><\/ol>

        4. Typesetting<\/h4>
        1. Highlighting<\/strong>: Enhancing bright areas in an image, often removing dots in the highlights to create more contrast.<\/li>\n\n
        2. Shadowing<\/strong>: Refers to dark tones in an image, also known as shadow areas.<\/li>\n\n
        3. System Crash<\/strong>: Not a literal disaster but a situation where insufficient memory or disk space causes a computer to crash.<\/li>\n\n
        4. Condensed Font<\/strong>: A type of font where the characters are narrower than usual.<\/li>\n\n
        5. Compressed Lettering<\/strong>: A style where characters are stretched vertically, creating tall, narrow letters.<\/li>\n\n
        6. Airbrush<\/strong>: A manual method used before digital tools to create smooth gradients and transitions in images.<\/li>\n\n
        7. Byte<\/strong>: A unit of digital information, typically consisting of 8 bits.<\/li><\/ol>

          These terms cover key aspects of the printing process from prepress to binding, offering a clear understanding of how design, printing, and post-printing processes come together to create a finished product.<\/p>

          In custom packaging design, visual decisions must also work in real printing and finishing. Color, typography, pattern, logo placement, foil stamping, embossing, spot UV and die-cutting should be checked during artwork review so labels, boxes and bags remain consistent in production.<\/p>
