Most laminated plastic pouches are printed by means of reverse printing. Reverse printing is the process of printing on the back side of a clear substrate.
In the following process, the print will be sandwiched between the outside substrate and the rest of the structure, offering scuff and chemical migration resistance.

When the outer substrate is mounted to the remainder of the structure, it will be right
reading.

10. How is your printing process going on?
The general printing rocures are as follows :
(1): A print production worker receives a job order and takes note of the specifications. They begin the setup process by installing the correct cylinders, preparing the ink, and other job-specific specs.
(2): Once the rolls of film arrive, a single roll is loaded onto the machine and the tension is adjusted.
(3): After once cycle is complete, the worker cuts a sample piece to analyze color accuracy.
Color accuracy is confirmed by looking at the sample through a light box, which emits a special lighting setup that has been adopted as an industry standard.
The workers in the printing department make decisions according to the sample artwork and PMS color guide book.
(4): Workers are constantly monitoring the accuracy of the artwork throughout the entire job order.

Since the machines run at an accelerated rate, workers look through a scanner, which can slow down the rate at which the film is traveling.
(5): A sample is taken from the end of every roll and inspected through the light box to verify there are no color deviations from roll-to-roll.
(6): Once the entire order has been printed, the rolls of film are delivered to either the laminating department or converting department for the next phase of the production process.
