RULE 239 - GRAPHIC ARTS OPERATIONS
(Adopted 11-03-94; Amended 6-08-95, 2-13-97, 8-14-97)

100 GENERAL

101 PURPOSE: To limit the emissions of volatile organic compounds from graphic arts operations.

102 APPLICABILITY:

103 EXEMPTIONS:

200 DEFINITIONS

201 CAPTURE EFFICIENCY: Expressed in percent, capture efficiency is the ratio of the weight of the VOC in the effluent stream entering a control device to the weight of the VOC emitted from graphic arts operations, both measured simultaneously in accordance with Section 502.5, and calculated by the following equation:
 

202 COATING: The application of a uniform layer of material across the entire width of a substrate. Those machines which have both coating and printing units are considered to be performing a graphic arts operation.

203 CONTROL DEVICE: Equipment such as an incinerator or adsorber used to prevent air pollutants from reaching the ambient air.

204 CONTROL DEVICE EFFICIENCY: Expressed in percent, control device efficiency is the ratio of the weight of the VOC removed by the control device from the effluent stream entering the control device to the weight of VOC in the effluent stream entering the control device, both measured simultaneously in accordance with Section 502.4, and calculated by the following equation:

205 CONVERTING OPERATION: Coating, waxing, laminating, extrusion coating and printing, for fabrication of base materials. The base materials are then used to produce wraps, bags, and other preformed packages.

206 DOCTOR BLADE: A steel blade used to scrape excess ink from a printing plate.

207 DRYING OVEN: An oven used to hasten the process of drying printed or coated material.

208 EXEMPT COMPOUNDS: For the purposes of this rule, Exempt Compounds are as defined in Rule 102, Definitions.

209 FLEXIBLE PACKAGING INDUSTRY: Establishments that convert materials consisting of light gauge papers, plastic films, cellulosic films such as cellophane, thin gauge metal sheets such as aluminum foil or steel foil, and combinations thereof into a variety of product packages.

210 FLEXOGRAPHIC PRINTING: A printing operation in which words, designs, or pictures are applied to a substrate by means of a roll printing technique in which a raised pattern is applied to an image carrier made of rubber or other elastomeric materials mounted on a steel matting cylinder. The image is then printed directly from the raised pattern to the substrate.

211 FOUNTAIN SOLUTION: The solution applied to the image plate to maintain the hydrophilic properties of the nonimage areas and to keep the nonimage area free from ink.

212 FUGITIVE EMISSIONS: Emissions of VOC from any portion of Graphic Arts Operations as defined in Section 213, other than the drying oven.

213 GRAPHIC ARTS OPERATIONS: Publication gravure, packaging gravure, specialty gravure, flexographic printing operations, lithographic printing operations, letterpress printing operations, or any coating or laminating operation that manufactures flexible packaging materials. Coating operations which are performed by a machine having only coating units and no printing units are not graphic arts operations.

214 GRAVURE PRINTING: An intaglio printing operation in which the ink is transferred from minute etched wells which comprise the image on a plate to the substrate which is supported by an impression roller, with excess ink removed from the plate by a doctor blade.

215 INTAGLIO PRINTING: A printing operation done from a plate in which the image is etched or engraved into the surface.

216 LAMINATING OPERATIONS: A process of composing two or more layers of material to form a single multiple-layer sheet by using adhesive as the bonding agent.

217 LETTERPRESS PRINTING: A printing operation in which the image area is raised relative to the nonimage area and the ink is transferred to the paper directly from the image surface.

218 LINE: The minimum equipment which is required for the application and/or curing of inks and/or coatings on a substrate, including the ink and/or coating applicators and heating oven(s) and associated ink and coating mixing equipment.

219 LITHOGRAPHIC PRINTING: A printing operation in which the image and nonimage areas exist in the same plane. The nonimage area is treated chemically so that only the image areas will be printed onto the substrate.

220 NONHEATSET INK: An ink which dries primarily by oxidation and absorption into the substrate without the use of heat from dryers or ovens, used primarily in lithographic and letterpress printing.

221 NONPOROUS SUBSTRATE: Any substrate other than paper or paperboard, including but not limited to foil, polyethylene, polypropylene, cellophane, metalized polyester, nylon and polyethylene terephthalate (mylar), but not including wood, metal, or ceramic materials.

222 OFFSET PRINTING: A lithographic printing operation in which the image area is transferred, or offset, to another surface, and then printed onto the substrate.

223 PACKAGING GRAVURE PRINTING: A gravure printing operation on paper, paperboard, foil, film or other substrates which are to be used to produce containers or packages.

224 POROUS SUBSTRATE: Paper or paperboard.

225 PRODUCTION UNIT: A ream of paper, consisting of 500 sheets of paper.

226 PUBLICATION GRAVURE PRINTING: A gravure printing operation on paper which is subsequently formed into books, magazines, catalogs, brochures, directories, newspaper supplements or other publication material.

227 SCREEN PRINTING: A printing operation in which the printing ink passes through a refined form of stencil to a web or fabric. The stencil openings determine the form and dimension of the imprint.

228 SPECIALTY GRAVURE PRINTING: A gravure printing operation for production of wall and floor covering, decorated household paper products such as towels and tissues, cigarette filter tips, vinyl upholstery, gift wrap, and woodgrains.

229 STANDARD INDUSTRIAL CLASSIFICATION (SIC): Number codes created by the U. S. Government Office of Management and Budget (OMB) to classify establishments by type of economic activity.

230 VOLATILE ORGANIC COMPOUNDS (VOC): Any chemical compound containing at least one atom of carbon except for the Exempt Compounds listed in Rule 102, Definitions.

231 VOC CONTENT OF FOUNTAIN SOLUTIONS, MAKEUP SOLVENTS, SURFACE PREPARATION SOLVENTS AND CLEANUP SOLVENTS: The weight of VOC per volume of material. It shall be determined using the appropriate test method pursuant to Section 502 and calculated by the following equation:
 

232 VOC CONTENT OF INKS, COATINGS AND ADHESIVES: The weight of VOC per liter of material, less water and exempt compounds. It shall be determined using the appropriate test method pursuant to Section 502, and calculated by the following equation:

233 WEB: A continuous sheet of substrate that is printed on web-fed printing presses.

234 WEB-FEED: An automatic system on a printing press which supplies a web substrate to the printing unit.
