• WYSIWYG – What you see is what you get; art prototype method
• Deckling – Fine papers “framed” in very roughened edges
• Twin Tac – Large sheets of double-sided adhesive/tape used in design prototyping (yes, still today)
Old School:
• Strripping – Arranging and joining film negatives as part the process of preparing printing plates
• Paper Lice – paper fragments that always made it into your hair after spending the day cutting & gluing down ad text
• Rubylith – used in many areas of graphic design, typically to prroduce masks for various printing techniques (not anymore!)
• TNT – “Tight but not touching” letterspacing to create unity
and, of course
• Spam – Nearly any unsolicited email, not hermetically sealed!
