Post printing: Ink printing on bags that are already made (see Printing Processes for full description).

Hot stamping: Another form of printing on bags that are already made. This uses foils that are adhered with heat instead of ink (see Printing Processes for full description).

Spot Printing: Printing single colors indicated in the artwork (see Printing Processes for full description).

Process Print: Printing using CMYK (Cyan, Magenta, Yellow, Black) for very intricate complicated print jobs with more than 4 colors (see Printing Processes for full description).

Printing and Converting: Printing on rolls of paper or plastic and converting the material to bags in the same process (see Printing Processes for full description).

Ink Coverage: Percentage of the surface of the bag that is covered by ink.

PMS Color: PMS (Pantone Matching System) is the universal color chart used in the print industry.

Registration: This refers to the position of multiple colors in a piece of artwork. If a piece of art has 2 colors and the 2 colors touch some where on the art, this is considered tight registration. We use the term registration because the colors must appear in the same spot every time.

Lead time: Amount of time for a job to be produced.

Over / Under Run %: Over and Under run is a percentage of the amount of bags that the job could end up over the initial quantity ordered or under the initial quantity ordered (see Printing Processes for full description).

Domestic Production: Bags produced in the USA.

Overseas Production: Bags produced in Asia.

LDPE: Low Density Polyethylene.

LLDPE: Linear Low Density Polyethylene.

PP: Polypropylene.

HDPE: High Density Polyethylene.

Formulas for calculating Weight per 1000 bags:
This formula is used to calculate the minimum number of bags needed for a run.

Material type: LDPE, LLDPE, Polypropylene
L X W / 3 X 2 X Gauge / 10 =
12 X 12 (144) / 3 (48) x 2 (96) X 2 gauge (192) / 10 = 19.2 lbs / 1000
19.2 lbs per 1000 / 500 lbs = 26,000 bags

HDPE L x W x .0686 x gauge = Weight per 1000 bags
12 x 12 (144) x .0686 x 1.5 mil = 14.82 lbs / 1000

For T-Shirt bags HDPE
After you get weight per 1000, take 10% off the number.

Example 18 lbs less 10% =16.2 lbs / 1000
