Step 5: The packaging company prints the product
Step 6: Processing after printing the packaging products
Step 7: Checking packaging quality and process delivery
Step 8: Listening to customer feedback and improve quality

Step 1: The packaging company exchanges ideas with customers

In addition to the common types of packaging available on the market, most customers prefer unique, specialized designs for their products. For completely new packaging samples, the packaging company will work with customers to:

Understand customers' ideas about the type of packaging to produce.
Understand the purpose that customers want when using this type of packaging: High-end gift paper bags or shipping carton boxes, labels for export products, or need POSM to introduce new products.
Decide the quantity and the deadline for the packaging manufacturing process.

The manufacturer will have the basis to consult the material, size, content, image, number of colors, and the best production technique.

If the customer already has a design, the idea exchange and consultation process are still necessary to unify the ideas and create the best packaging products.

Step 2: The packaging company will design the structure and product images

In this step, the packaging company will visualize customers' ideas and needs on appropriate design software. Includes shape, structure, information, and photos of the packaging.

The structure design not only shows the shape but also calculates the capacity, bearing capacity when stacked, even measures the feasibility of hanging or displaying products on shelves.

From the structure, the information to the image shown on the packaging is visualized by the designer

Step 3: The packaging company prints and samples the products

After structure and image design, the packaging company will make a real design pattern to check the shape, information on the product, color, capacity, bearing of the product to adjust (if necessary). This step aims to check the viability of the package; customers approve the sample and approve the color before mass production.

Thanks to proof prints (printed samples), both parties can minimize errors before producing packaging, such as informative content, images, typo, unreasonable content; fonts; sizes; colors, or errors related to handwriting alignment; margins, the layout of bricks, and letters.

Compared to fast printing, proof printing is significantly superior because the color resolution mode of proof printing is similar to offset printing.

Step 4: The packaging company will make molds and process printing

One of the most important steps in the packaging process is molding. Molding is the process of arranging prints on the size of the paper to be printed, placing color scales, tram colors, and safety cradles so that the post-printing process is easy.

Set the CMYK color, the color scale at the 4 corners, and 2 upper and lower edges of the print so that when printing, the printer recognizes C, M, Y, and K colors and easily align the colors.

Next, arrange the printouts in the most optimal way. In this stage, the designer will calculate and measure to have a quality product but still ensure the economy, including:

Printouts are arranged to fit the size of the paper (to reduce the waste of paper)
Arrange suitable prints for the most convenient and quick process after printing.
Screen printing is the process of creating images to be printed on aluminum sheets as offset prints, exporting zinc for CTP.

Printouts will fit in the paper size, not only to save costs but also to speed up production

Step 5: The packaging company prints the product

The packaging company will use the offset printer to print the images of the packaging on paper. The machine will print from 3 to 8 colors depending on the design. Offset printing has many outstanding advantages, making it the most favored technique. The outstanding advantages of offset printing include the following:

The image quality is higher, sharper, and cleaner than printing directly from the print to the paper because the rubber pad is evenly applied to the surface.
Applicable on many surfaces, including non-flat surfaces (such as wood, cloth, and rough leather)
Easier to print
Last longer

Step 6: Processing after printing the packaging products

After printing, depending on the requirements of each product, the packaging company will perform the following print processing steps:

Die cutting: cut and groove printed sheets according to the designed shape.
Stamping, embossing: emphasize a detail on the packaging such as logos, slogans, or texts on or under the surface
Laminating, UV/IR/Varnish coating: covering the surface of publications with a layer of the polymer film.

Step 7: Check packaging quality and process delivery

After manufacturing, the packaging company will discard unqualified packaging products such as wrinkled paper, corrugated, scratched printing surfaces, torn paper, and peeling glue. The inspection is based on certain quality standards. This step ensures the packaging products delivered to customers can achieve the highest accuracy.

Delivery time depends on the quantity and requirements of customers. In Khang Thanh, customers can receive products from 7-10 days after closing orders.

Step 8. Listen to customer feedback and improve quality

“We all need people who will give us feedback. That's how we improve”. Listening to customers' opinions is one of the important steps in the development journey. This step is often the customer feedback on packaging products, service quality, delivery progress to help the packaging company improve and provide a better experience for partners.
