Current through Vol. 24-12, July 15, 2024
Rule 635.
(1) As
				used in this rule:
(a) "Batch" means a supply
				of fountain solution that is prepared and used without alteration until
				completely used or removed from the printing process. Batch applies to
				solutions prepared in discrete batches or solutions that are continuously
				blended with automatic mixing units. A fountain solution that is continuously
				blended with an automatic mixing unit is considered to be the same batch until
				the recipe or mix ratio is changed.
(b) "Cleaning solution" means liquid solvents
				or solutions used to remove ink and debris from the operating surfaces of the
				printing press and its parts including blanket washes, roller washes, plate
				cleaners, metering roller cleaners, impression cylinder cleaners, rubber
				rejuvenators, and other cleaners used for cleaning a press, press parts, or to
				remove dried ink from the areas around a press. Cleaning solution does not
				include cleaners used on electronic components of a press, pre-press cleaning
				operations, post-press cleaning operations, cleaning supplies used to clean the
				floor of the area around a press, other than dried ink, or cleaning performed
				in parts washers or cold cleaners.
(c) "Letterpress printing line" means all
				operations of letterpress printing processes characterized by the image area
				being raised relative to the nonimage area and including, but not limited to,
				pre-press and post-press operations that support the activity. Varnishes,
				glues, and other coatings that are applied by a letterpress printing process
				are part of the letterpress printing operations and are not considered as a
				separate process, for example, paper coating.
(d) "Non-heatset" means a lithographic
				printing process where the printing inks are set without the use of heat and
				dry by absorption or oxidation, or both. 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.
(e) "Offset lithographic printing line" means
				offset printing presses characterized by a planographic plate where the image
				and nonimage area are in the same geographical plane and the related processes
				necessary to directly support the operation of those offset lithographic
				printing processes including, but not limited to, pre-press and post-press
				operations. Varnishes, glues, and other coatings that are applied by an offset
				lithographic printing process are part of offset lithographic printing
				operations and are not considered as a separate process, for example, paper
				coating.
(f) "Printing process"
				means any equipment, operation, or system where printing ink or a combination
				of printing ink, surface coating, or adhesive is applied, dried, or cured. A
				printing process may include any equipment that applies, conveys, dries, or
				cures inks or surface coatings including, but not limited to, presses, digital
				output devices, fountain solutions, heaters, and dryers.
