  1. 1. <ul><li>Trim </li></ul><ul><li>Physical Parts </li></ul><ul><li>Signatures and Flats </li></ul><ul><li>Lithography </li></ul><ul><li>Halftones and continuous tones </li></ul><ul><li>Color printing </li></ul><ul><li>Binding methods </li></ul>
  2. 4. <ul><li>A signature is a large sheet of paper which is eventually folded down to page size. </li></ul><ul><li>Each side of the unfolded signature holds eight pages and is called a flat . </li></ul><ul><li>When the signature is sent through the printing press, these eight pages are printed at one time. </li></ul>
  3. 5. <ul><li>On each signature, there are only two facing pages which will be printed side-by-side naturally . </li></ul><ul><li>These pages are called a natural double-page spread or simply a natural spread . </li></ul><ul><li>Even though you can design layouts where elements extend across the gutter on any double-page spread, the best place for this is a natural spread. </li></ul>
  4. 6. <ul><li>Two facing pages are called double-page spread, and the fold between them is the gutter. </li></ul>
  5. 7. <ul><li>A process used to print yearbooks is called offset lithography. Image areas are flat and printing plate is completely flat. </li></ul><ul><li>Older methods were called letterpress . Image areas were raised. </li></ul>
  6. 8. <ul><li>Based on the principle that grease attracts ink, cylinder called the blanket . The image is then transferred to the paper. </li></ul><ul><li>Example: With Silly Putty you can pick up a newspaper image. The putty is slightly greasy so the ink sticks to it. </li></ul>
  7. 9. <ul><li>Continuous tones : shades vary gradually from black to white. </li></ul><ul><li>Before being printed in your yearbook, continuous tone photos are transformed into halftone negatives. A halftone picture presents the illusion of a continuous tone when seen from a normal reading distance. </li></ul>
  8. 10. <ul><li>Three primary colors are, blue red, yellow. They combine to make all the other colors. </li></ul><ul><li>The term four color printing refers to cyan (blue), magenta (red), yellow and black to reproduce the colors in a color photograph or original color artwork. </li></ul>
  9. 11. <ul><li>The combination of the four printing colors requires four printing plates made from four halftone negatives called separations . </li></ul><ul><li>To make the separations, the original color photos or artwork are placed on a laser scanner to begin the complex printing process. </li></ul>
  10. 12. <ul><li>A spot color is any color, other than black, printed in addition to black on a page. </li></ul><ul><li>Separate printing plates are made for the black and the additional color(s). </li></ul><ul><li>When printing a spot color, the paper passes through the two units of the press only once, as in four-color printing. </li></ul>
  11. 13. <ul><li>The yearbook cover is created by wrapping cover material around two pieces of durable fibrous binder’s board. </li></ul><ul><li>This procedure is called case-making because the printing term for a book cover is case. </li></ul><ul><li>A case is comprised of a front lid, back lid and spine . </li></ul><ul><li>Endsheets are the heavy-stock paper that hold the contents into the case. (Front & Back) </li></ul>
  12. 14. <ul><li>Signatures are gathered in sequence and sewn together. </li></ul><ul><li>Each signature is sewn individually with a strong, wax-coated thread while connecting all signatures with a continuous thread at the spine of the book. </li></ul><ul><li>Binding by sewing allows the book to open flat. </li></ul><ul><li>Once sewn, the pages are trimmed and the sewn edge is coated with glue and two strips of cloth to give the spine added strength. </li></ul><ul><li>Books of 160 or more pages are then rounded and backed on a machine. </li></ul><ul><li>Finally, on the casing-in machine, the endsheets are glued to the inside of the cover and the book is dried in a hydraulic press. </li></ul>
