(34) Printing--In the graphic arts, is any operation
that imparts color, design, alphabet, or numerals on a substrate.
(35) Removable press component--A part, component,
or accessory of a press that is physically attached to the press but
is disassembled and removed from the press prior to being cleaned.
Rollers, blankets, metering rollers, dampening rollers, ink trays,
printing plates, fountains, impression cylinders and plates shall
not be considered as removable press components.
(36) Repair cleaning--A solvent cleaning operation
or activity carried out during a repair process.
(37) Repair process--The process of returning a damaged
object or an object not operating properly to good condition.
(38) Roller wash--A solvent used to remove ink from
the rollers of a press.
(39) Scientific instrument--An instrument (including
the components, assemblies, and subassemblies used in their manufacture)
and associated accessories and reagents that is used for the detection,
measurement, analysis, separation, synthesis, or sequencing of various
compounds.
(40) Screen printing--A process in which the printing
ink passes through a web or a fabric to which a refined form of stencil
has been applied. The stencil openings determine the form and dimensions
of the imprint.
(41) Solvent--A volatile organic compound-containing
liquid used to perform solvent cleaning operations.
(42) Solvent cleaning operation--The removal of uncured
adhesives, inks, and coatings; and contaminants such as dirt, soil,
oil, and grease from parts, products, tools, machinery, equipment,
vessels, floors, walls, and other work production-related areas using
a solvent. In the context of the provisions in §115.461(d) and
(e) of this title and §115.463(e) of this title, each distinct
method of cleaning in a cleaning process that consists of a series
of cleaning methods shall constitute a separate solvent cleaning operation.
(43) Solvent flushing--The use of a solvent to remove
uncured adhesives, uncured inks, uncured coatings, or contaminants
from the internal surfaces and passages of the equipment by flushing
solvent through the equipment.
(44) Specialty flexographic printing--Flexographic
printing on polyethylene or polypropylene food packaging, fertilizer
bags, or liquid-tight food containers.
(45) Stereolithography--A type of printing process
that employs a system using a light to solidify photocurable resins
in a desired configuration in order to produce a 3-dimensional object.
(46) Stripping--The removal of cured coatings, cured
inks, or cured adhesives.
(47) Surface preparation--The removal of contaminants
such as dust, soil, oil, grease, etc., prior to coating, adhesive,
or ink applications.
(48) Ultraviolet ink--An ink that dries by polymerization
reaction induced by ultraviolet energy.
(49) Volatile organic compound (VOC) composite partial
pressure--The sum of the partial pressures of the compounds that meet
the definition of VOC in §101.1 of this title (relating to Definitions).
The VOC composite partial pressure is calculated as follows.
