Bitmapped Art
Bitmapped art is created out of little dots of color For
multi-colored, screen printed art bitmapped files such as .jpeg or
.bmp will in most cases not be acceptable. Occasionally separations
can be extracted but will incur art charges. For any bitmapped art
whether 1 or multi-colored, the resolution must be at least 300
dpi.
Bleeds:
Refers to areas that are printed over the dieline (cut edge).
Background art should extend or “bleed” over the planned cut edge
by 1/8”. An example product would be a business card magnet with a
full color background.
CMYK
Stands for “Cyan, Magenta, Yellow, Black,” which are the four
process inks used in four-color process.
Debossing
The image is depressed into a material such as paper, leather or
metal, so the image sits below the product surface.
Decal
transfer
The decal is printed on an offset or letterset press, submerged in
water and placed on the product. Excess water and air is pressed
out and the product is kiln-fired, fusing the decal with the glaze
(e.g. bar ware, china, porcelain).
Die-casting
Molten metal is injected into the cavity of a carved die (a mold);
similar to how a sculpture would be made (e.g. bookends,
paperweight).
Die-striking
A method of producing emblems and other flat promotional products
by striking a blank metal sheet with a hammer that holds the
die.
DPI
Stands for “dots per inch” in some scanners and computer programs.
Computers make art with little dots known as pixels. The dpi is the
way to set picture resolution. The more dots in an inch, the higher
the picture resolution. Images should be made at 300 dpi or higher.
Smaller dpi will create an image that is ragged, stair-stepped,
grainy or blurry when printed.
Embedment
An object is suspended in a clear substrate (e.g. Lucite) for use
as a paper weight, trophy, etc.
Embossing
The raising of an image on a product by pressing the material
between concave and convex dies.
Embroidery
A design stitched into fabric through the use of high-speed,
computer-controlled sewing machines.
Engraving
Cutting an image into metal, wood or glass by one of three methods
- computerized engraving, hand tracing, or hand engraving.
EPS
Stands for “Encapsulated Postscript.” In most art programs EPS is a
saving option, or at least an exporting option. Line and vector art
files should be saved as EPS. People tend to forget to save their
Illustrator files as EPS files thinking all Illustrator files are
EPS. You actually need to turn EPS “on” in the save menu.
Etched
An image is covered with a protective coating that resists acid.
The image is then exposed, leaving bare metal and protected metal.
The acid attacks only the exposed metal, leaving the image etched
onto the surface.
Four-Color
Process
A method used to achieve a full range of colors, tints and
gradations using only the four process colors of cyan, magenta,
yellow and black (CMYK). Typically a full color original
photograph, drawing or other artwork is used to generate four
separate printing plates, one for each of the process colors. When
printed, the resulting image is composed of a myriad of microscopic
dots comprised of the four colors. These tiny colored dots have
varying sizing and spacing between them so they blend optically to
produce (to the eye and brain of the viewer) a good approximation
of the original full-color image.
Hot
stamping
A dry imprinting process in which a design is set on a relief die,
which is then heated and pressed onto the printing surface.
JPEG
Stands for Joint Photographic Experts Group. It is designed for
compressing either full-color or gray-scale images of natural,
real-world scenes. It works well on photographs, naturalistic
artwork and similar material. It does not work well on lettering or
line drawings.
Manufacturer
A company that creates promotional products, which are then shipped
to distributors for sale to the public.
Offset
lithography
A printing process in which the image is transferred to a rubber
blanket, which in turn applies it to the surface to be
printed.
Pad
printing
A recessed surface is covered with ink. The plate is wiped clean,
leaving ink in the recessed areas. A silicone pad is then pressed
against the plate, pulling the ink out of the recesses, and
pressing it directly onto the product.
Postscript
This is the language that tells a computer and a printing device
how to read your artwork. It treats images, including fonts, as
collections of geometrical objects rather than as bitmaps.
Postscript fonts are called outline fonts because the outline of
each character is defined. They are also scalable fonts because
their size can be changed with Postscript commands.
Screen-printing
An image is transferred to the printed surface by ink, which is
pressed through a stenciled screen and treated with a
light-sensitive emulsion.Film positives are put in contact with the
screens and exposed to light, hardening the emulsion not covered by
film and leaving a soft area on the screen for the squeegee to
press ink through. (Also called silk-screening.)
Spot Colors
Printing with spot colors uses any number of specific colored inks
(rather than just CMYK) to match exactly each individual hue
specified by the designer of a piece of artwork. Spot color inks
are mixed according to formulas. This method is good for artwork
with just a few colors. Otherwise, four-color process should be
used.
TIFF
Stands for Tagged Image File Format. The image is bitmapped art
which is created out of little dots of color. Tiff files are good
formats for scanning images, as long as the resolution is high
enough.
Vector
Art
This is art created in a vector-based program. Vector art consists
of creating paths and points in a program such as Illustrator or
Freehand. The program keeps track of the relationships between
these points and paths. Vectors are any scalable objects that keep
their proportions and quality when sized up or down. They are
defined as solid objects. Vector art is great for type because the
lines stay crisp at any scale.
