What is Offset Printing & How it Work?

Offset printing is the most commonly used printing method. The procedure involves transmitting the inks from a plate to a rubber blanket and then onto the material. 

This printing procedure is renowned for producing high quality prints and is traditionally employed for large volume production runs. This printing method is known for producing exceptionally crisp, vibrant, and consistent printing results. In this piece, we will discuss how offset printing works on mylar bags and what its advantages are. 

How Offset Printing Works

Now that you understand what is an offset print process, it is also important to learn how it works. This printing process is widely utilized to print brilliant and eye catching designs on Mylar bags. Below is the step by step process of how it works:

• The entire printing process starts by breaking down digital design into four colors, such as cyan, magenta, yellow, and key (CMYK).

• Then a laser etches the design for all the colors on a metal plate that holds the image to be printed. 

• The plates are then passed through a dampening system, which allows water to stick on the blank parts of the design. 

• Then the ink is applied onto the etched design. The inked design is pasted onto a flexible rubber roll.

• The mylar sheet is squeezed between the rubber blanket and a metal cylinder, creating a vibrant print on the surface. 

What Are the Benefits of Using Offset Printing?

Offset print is the best printing option for large volume production runs. It can be costly for short production runs. Therefore, it is best to use this printing method for bulk orders. However, offset printing offers many amazing benefits, such as:

• Best Color Match: This printing method uses the exact color formulas known as PMS. This allows them to match colors with your brand across all batches. 

• Sharp Images: The rubber rollers wrap around the mylar bags, which creates crisp lines and helps complex pictures look sharp. 

• Lowers Cost for Large Orders: The cost drops when you print mylar bags in bulk. 

These are the best advantages of offset printing.
