CMYK
Acronym for Cyan Blue, Magenta, Yellow, and Black. Printing colors for Process Color reproduction.
Continuous Tone
A screen image which contains gradient tones from black to white.
Dots per Inch
A measure of the resolution of an image. The more dots per inch, thee finer the screen, and the greater the detail. Also referred as “LPI”, lines per inch. DPI or LPI tolerances are dependent on the method of printing along with the finish of the printing surface.
Double Wall Bag
A bag that is made out of two layers of poly film. The outer layer is usually clear.
Draw Closure Bag
Closure for this bag is made from either a choice of poly tape or cotton string.
These materials are inserted through a heat sealed fold-over hem at the top of the bag.

numbers, and punctuation marks of a given size and design.
Four-color process
The printing process that reproduces colors by combining, cyan, magenta, yellow and black. If you look through a magnifying glass, you'll see that the
printed image consists of dots in these four colors. These dots are printed on top of each other, next to each other or just close to each other, depending
on the color and tonal values wanted.

You can achieve great visual results by using only one color for any fine print on paper, for printing on tote bags and coarser materials in silkscreen technique
this method is not always recommended. Final print results might appear "blotchy".
Gusset
The side and/or bottom measurements of a paper or poly bag.
Halftone
A continuous-tone image photographed through a screen in order to create small dots of varying sizes that can be reproduced on a printing press. Digital
halftones are produced by sampling a continuous-tone image and assigning different numbers of dots, which simulate different sized dots, for the same effect.
Generally refers to one-color dot imprints.
Halftone screen
The screen through which a continuous-tone image is photographed, measured in lines per inch. Although digital halftones are not actually photographed through
a screen, the term is still used to describe the size of the dots; the larger the dots (fewer lines per inch), the more grainy the image. Special screens can be used
for special effects.
Heat Transfer Imprint
Is a dry process that uses preprinted decals to decorate an item. Heat transfer decals provide a high quality screened image that is permanently bonded to a part
by way of the hot stamping process. You are able to achieve almost paper print like results when using heat transfer process and are not limited to a minimum
stroke size as you are in screen printing. Natural and white bags can be decorated more easily and are more cost effective than heat transfer on a dark background.

Sans serif typeface
A typeface that has no serifs, such as Helvetica or Swiss. The stroke weight is usually uniform and the stress oblique, though there are exceptions.
Scaling
Reduction or enlargement of artwork, which can be proportional (most frequently) or disproportional. In desktop publishing, optimal scaling of bitmaps
is reduction or enlargement that will avoid or reduce moiré patterns.
Screen (tint)
In graphic arts, a uniform dotted fill pattern, described in percentage (for example, 50 percent screen).
Script
Connected, flowing letters resembling hand writing with pen or quill. Either slanted or upright. Sometimes with a left-hand slant.
