A regola d'arte
The phrase "according to best practice" refers to the set of techniques considered correct for performing specific tasks, typically in crafts or manufacturing. The "Art" mentioned refers to the professional category of the person expected to follow these rules. The origin of this concept dates back to trade guilds, which established detailed regulations on materials, tools, procedures, and methods to ensure product or service quality.
Bleed
In graphic design, this refers to the printed area extending beyond the cutting lines. A minimum of 3 mm is recommended, especially when color extends to the edge.
Lamination
The process of bonding two or more materials using vinyl glue and a laminating machine, forming a single, more durable sheet. Typically involves offset-printed board applied to corrugated cardboard or other materials like Laminil.
Water (Offset Printing)
One of the three essential materials in offset printing (alongside ink and paper). The dampening solution contains water with controlled hardness, stabilizing additives, and a balanced pH.
Closure Flaps
Parts of a box that close the packaging. Based on position and locking system, they can be called “airplane-style,” “opposed,” “simple,” “dovetail,” or “non-return.”
Corrugated Wave Height
Measurement of the thickness of corrugated board, referring to the flute direction.
Box Height – H
Indicated by “H,” it defines the internal height of a closed package (usable space between top and bottom).
Honeycomb Divider
A multi-compartment insert used in boxes to protect items like bottles.
American Box
See “Regular Slotted Container” (standard shipping box style).
Anchoring
The degree to which blister packs adhere to cardboard during heat sealing.
Anti-Set-Off Powder
Fine starch dust sprayed on sheets in high-pile offset printing to prevent ink transfer between sheets. Used sparingly when varnish will be applied later. Also available as a paste for ink fountains, though less effective.
Dry Printing (Asciutto)
In offset printing, improper balance between ink and water can cause a “dry” effect (not enough water), leading to quality issues.
Assembly
The joining of multiple components by gluing or interlocking (e.g., for displays, boxes with inserts, or multi-part boxes).
Astralon
A transparent, rigid plastic sheet used in the film layout for offset printing plate production.
Millimeter Astralon
A transparent gridded sheet placed on a light table to help with precise alignment during film layout.
Folding Carton (Astuccio)
A printed, die-cut paperboard packaging designed to contain, promote, and sometimes protect a product. Typically small to medium in size, with one or two reclosable openings. Many variants exist (e.g., various closure types, euro hooks, glued bottoms, or locking tabs).
Self-Locking (Automontante)
Refers to packaging that doesn't require glue to form its shape. Assembly is done via pre-cut folds and interlocks.
Kraft (Avana)
The brownish paper color commonly used for corrugated cardboard. The name references the color of Cuban cigars from Havana (La Habana).
Setup Cost (Avviamento)
All the operations required to start each production phase. Setup cost is spread over the print run: the more units produced, the lower the cost per unit.
