Double Cast: This type of casting is performed for various applications, such as those requiring copy to show on three or more sides of piece.
dpi: Dots per Inch. Unit of measure used for the resolution of a picture. Also known as "pixels per inch".
Drop Shipping: Shipping of merchandise direct to the end-user.

Font: A complete set of letters, numbers, punctuation, and special characters of a particular size from the same typeface available in typesetting.
Four-Color Process: Color printing technique by which four colors — cyan, magenta, yellow, and black— are used for producing a full color picture that can be similar to a photograph.
H
Halftone: Screened reproduction of an original made up of dots varying in size to create the illusion of a variation in tone. Can be done in various colors.
J
JPEG: Joint Photographic Experts Group. Standard compression format used for files containing high-resolution color images.
L
Laser Engraving: An imprinting method by which electronic artwork is etched on acrylic surface by a laser beam.
Laser Plexiglas™ Cutout: Various patterns can be cut out of Plexiglas™ by laser and used as embedments. Many colors are available.
Lasergram®: Engraving done inside acrylic piece.
Layer: When embedments are required on different levels within the acrylic piece to produce an effect of depth, they need to be cast in separate layers.
Logo: Broadly defined, it is any drawing, illustration, symbol, abbreviation, lettering style, or word that is legally registered by a company and used for identification purposes. Also known as "trademark".
lpi: Lines Per Inch. Number of lines of dots in one linear inch.
M
Marbleized Acrylic: Partial blend of two or more acrylic colors to produce a marble look.
Matchprint®: A color proof made from superimposing four color films (cyan, magenta, yellow, and black). Color accuracy rate: 95%.
Metal Casting: Miniature metal figurine with a gold, silver or bronze color finish used as an embedment for an acrylic piece.
Metal Plate: Aluminum or brass plate featuring silkscreened artwork on one or both sides and used as an embedment in an acrylic piece.
Model Piece: Original master version in 3-D used for making reproductions.
Mold: A custom-built shape into which a viscous acrylic mixture is poured to produce acrylic pieces.
O
Offset Printing: A printing process where a positive image is transferred to a rubber blanket in reverse, which in turn applies it to the paper, right reading.
P
Paper Insert: A white piece of cardboard used as an embedment with artwork silkscreened on one or both sides.
Paper Proof: A PDF version of an order sent via email for a client to edit or approve.
PMS™: Pantone Matching System. Trademark of a color scale commonly used for precisely matching colors for printing. Each hue comes with a coded number, which indicates instructions for mixing inks to achieve color match.
Polishing: The 1st polishing step consists in a rough buffing to remove sanding lines and scratches. The 2nd polishing step is the final hand polishing to bring out luster and thus the crystal-like finish of an acrylic piece.
Positive: Image reproduction with the same density values as the original.
Pre-Production Sample: Production of a sample of the finished product featuring the specifics of a purchase order for the purpose of checking whether the product’s appearance and printing correspond to client’s expectations prior to processing the whole order.
R
Random Sample: A piece that was previously produced in excess of the quantity ordered by a client (overrun) and was not shipped. It is kept as a potential sample that may be sent to a prospective client who wishes to have an idea of the finished product prior to ordering.
Recess: Depression of an image or a shape into a product's surface.
Resolution: Clarity of the picture defined by the number of pixels per inch on a screen or by the number of dots per inch on a printed document. Its unit of measure is dpi.
S
Sandblasting: A blast of air or steam laden with sand, used for decorating an acrylic surface. Can be done on entire surface with or without special patterns.
Scanning: Digitizing a document and converting it into an image using dots in order to enable its electronic handling. It consists in the transformation of analogical data into numerical data.
Screenprinting: Printing method by which image is transferred to printed surface by squeegeeing ink through a stenciled screen stretched over a frame. In this process, screens are treated with a light-sensitive emulsion. Then, film positives are put in contact with screens and exposed to light, which hardens emulsion not covered by film, leaving a soft area on screen for squeegeed ink to be forced through. Also called "silkscreening".
Sizing: Since piece is cast oversized to allow for shrinkage, the 1st sanding grinds piece to size with wet coarse grit sander belt. In the 2nd sanding step, sizing process continues with medium grit belt. The purpose of the 3rd sanding step with fine grit belt is to properly prepare piece for a smooth, flawless finish.
T
Touch-Up: The process of correcting a picture or improving its appearance before producing a proof.
Transparency: Full-color, translucent, photographic film positive.
Trapping: A technical action that ensures adjacent colors overlap enough to take into account any possible variation during printing.
Trim Line: Line on artwork indicating where to cut to remove the waste on a printed piece.
Trimming: Technique that consists in cutting the margins in order to make the sheets even.
