Section 250-RICR-120-05-21.5 - DefinitionsA. Unless otherwise expressly defined in this section, the terms used in this regulation shall be defined by reference to Part 0 of this Subchapter (General Definitions). As used in this regulation, the following terms shall, where the context permits, be construed as follows: 1. "Capture efficiency" means the ratio of VOC emissions delivered to the control device to the total VOC emissions resulting from operation of a flexible package printing press and related cleaning, expressed as a percentage;2. "Cleaning" means with respect to printing press operations, cleaning of a press or press parts or the removal of dried ink from areas around the press. a. "Cleaning" does not include cleaning of electronic components, cleaning in platemaking or binding operations, housekeeping activity near a press or the use of a parts washer or cold cleaner.3. "Cleaning solution" means any liquid solvent or solution used to clean the operating surfaces of a printing press and its parts. For purposes of this regulation, cleaning 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.4. "Coldset" or "non-heatset" means a printing process in which the ink dries on the substrate through ordinary evaporation and absorption. For the purposes of this Part, ultraviolet-cured and electron beam-cured inks are considered coldset or non-heatset.5. "Control device efficiency" means the ratio of VOC emissions recovered or destroyed by the control device to the total VOC emissions that are introduced into the device, expressed as a percentage.6. "Emission baseline" means a level of emissions calculated by multiplying two factors: a. The lowest of the source's actual or allowable emission rate in emissions per unit of production; and b. The source's actual capacity utilization, or units of production, over some representative time period. Generally, the time period is the preceding two (2) years unless the source can demonstrate that those years were not representative of historical production.7. "Flexible package" means any package or part of a package the shape of which may be readily changed. A "flexible package" includes any bag, pouch, liner or wrap made of paper, plastic, film, aluminum foil, or metalized or coated film or paper, alone or in combination. a. Flexible package does not include any folding carton, self-adhesive labels, gift wrap, wall covering, vinyl products, decorative laminates, floor coverings or tissue products.8. "Flexographic printing" means the application of words, designs and/or pictures to a 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.9. "Fountain solution" means with respect to offset lithographic printing, a water-based solution that contains small amounts of gum Arabic or synthetic resins, acids, buffer salts and a wetting agent or dampening aid applied to the image plate to reduce the surface tension of the solution.10. "Fountain solution reservoir" means the collection tank that accepts fountain solution recirculated from printing unit(s). In some cases, the tanks are equipped with cooling coils for refrigeration of the fountain solution.11. "Heatset" means a lithographic printing process where the printing inks are set by the evaporation of ink oils in a heatset dryer.12. "Heatset dryer" means any device used in heatset web offset lithographic printing to heat the printed substrate and to promote the evaporation of ink oils.13. "Letterpress printing" means a printing process in which the image area is raised relative to the non-image area, and the paste ink is transferred to the substrate directly from the image surface;14. "Lithographic printing" means a printing process in which the image and non-image areas are chemically differentiated, i.e., the image area is oil receptive and the non-image area is water receptive.15. "Offset lithographic printing" means a printing process that transfers the ink film from the lithographic plate to an intermediary surface which is a rubber covered roller or blanket, which, in turn, transfers the ink film to the substrate.16. "Packaging rotogravure printing" means rotogravure printing upon paper, paper board, metal foil, plastic film or other substrates, and other substrates, which are, in subsequent operations, formed into packaging products and labels for articles to be sold.17. "Printing press" means equipment used to apply words, pictures, or graphic designs to either a continuous substrate or a sheet. A continuous substrate consists of paper, plastic, or other material that is unwound from a roll, passed through coating or ink applicators and any associated drying areas. The press includes all coating and ink applicators and drying areas between unwind and rewind of the continuous substrate. A sheet consists of paper, plastic, or other material that is carried through the process on a moving belt. The press includes all coating and ink applicators and drying operations between the time that the sheet is put on the moving belt until it is taken off.18. "Publication rotogravure printing" means rotogravure printing upon paper which is subsequently formed into books, magazines, catalogues, brochures, directories, newspaper supplements, or and other types of printed materials.19. "Retention factor" means the factor relating to the portion of volatile organic compounds contained in inks and cleaning solution is that retained in the printed web or in the shop towels used for cleaning.20. "Roll printing" means the application of words, designs and/or pictures to a substrate by means of a series of hard rubber or steel rolls each with only partial coverage.21. "Rotogravure printing" means the application of words, designs and/or pictures to a substrate by means of a roll-printing technique, in which the pattern to be applied by the printing roll is accomplished by an intaglio or recessed image areas in the form of cells.22. "Sheet-fed printing" means with respect to offset lithographic printing, a process in which individual sheets of paper or other substrate are fed to the press.23. "Specialty printing" means all other rotogravure and flexographic printing operations, excluding publication printing and packaging printing.24. "Volatile organic compound" or "VOC" means "Volatile Organic Compound and Halogenated Organic Compound" or "VOC and HOC".25. "Web printing" means with respect to offset lithographic printing, a process where continuous rolls of substrate material are fed to the press and rewound or cut to size after printing.250 R.I.
