R307-351-4. Definitions

  The following additional definitions apply to R307-351:

  "Alcohol" means any of the following compounds, when used as a fountain solution additive for offset lithographic printing: ethanol, n-propanol, and isopropanol.

  "Alcohol Substitute" means a non-alcohol additive that contains VOCs and is used in the fountain solution.

  "Cleaning materials and solutions" means a liquid solvent or solution used to clean the operating surfaces of a printing press and its parts. Cleaning materials and solutions include, but are not limited to blanket wash, roller wash, metering roller cleaner, plate cleaner, impression cylinder washes, rubber rejuvenators, and other cleaners used for cleaning a press, press parts, or to remove dried ink or coating from areas around the press.

  "Blanket" means a synthetic rubber material that is wrapped around a cylinder used in offset lithography to transfer or "offset" an image from an image carrier.

  "Control system" means the combination of capture and control devices used to reduce emissions to the atmosphere.

  "Flexographic printing" means the application of words, designs, and pictures to substrate by means of a roll printing technique in which the pattern to be applied is raised above the printing roll and the image carrier is made of rubber or other elastomeric materials.

  "Fountain solution" means a mixture of water and other volatile and non-volatile chemicals and additives that wets the non-image area of a lithographic printing plate so that the ink is maintained within the image areas.

  "Graphic arts materials" means any inks, coatings, or adhesives, including added thinners or retarders, used in printing or related coating or laminating processes.

  "Graphic arts printing" means the application of words and images using the offset lithographic, letterpress, rotogravure, or flexographic printing process.

  "Heatset" means an offset lithographic printing or letterpress printing operation in which the ink solvents are vaporized by passing the printed surface through a dryer.

  "Letterpress printing" means a method where the image area is raised relative to the non-image area and the ink is transferred to the substrate directly from the image surface.

  "Non-heatset", also called coldset, means an offset lithographic printing or letterpress printing operation in which the ink dries by oxidation and/or absorption into the substrate without use of heat from dryers. For the purposes of this rule, use of an infrared heater or printing conducted using ultraviolet-cured or electron beam-cured inks is considered non-heatset.

  "Medical device" means an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent or other similar article including any component or accessory, that is intended for use in the diagnosis of disease or other conditions or in the cure, mitigation, treatment, or prevention of disease, or is intended to affect the structure or any function of the body. For the purpose of this rule, a medical device shall also include associated manufacturing or assembly apparatus.

  "Offset lithographic printing" means a plane-o-graphic method in which the image and non-image areas are on the same plane and the ink is offset from a plate to a rubber blanket, and then from the blanket to the substrate.

  "Printing operation" means the application of words, designs, or pictures on a substrate. All units in a machine which have both coating and printing units shall be considered as performing a printing operation.

  "Rotogravure printing" means the application of words, designs, and pictures to a substrate by means of a roll printing technique that involves a recessed image area in the form of cells.

  "Web" means a continuous roll of substrate.
