Making Perfect Box Printings


The medium for this type of printing is a variety of packing materials. Patterns, phrases, and other visual elements are used to improve the visual appeal of the product, convey information, and increase sales. Printing of packing cartons, bottles, cans, and other packaging materials is included. Printing on packaging is an important aspect of packaging engineering and is widely used in the printing and packaging industries. This guide will show you the best tips and tricks for creating perfect packaging printings.

1. Take note of the observation examples.

Sampling for packaging and printing quality control. The ink and water supply flow indicated at the start of printing will be revised shortly after the announcement of packaging and printing. It is critical to perform regular sampling inspections and readjustments. If the printing rate remains constant and the ink and water supply flows remain consistent, samples should be inspected at a rate of 500-1000 per print. Insert the cautionary message. Long and thin warning strips should be clamped as a mark in the regions where common defects occur during announcement packing and printing to simplify examination in the following process flow.

2. Monitor the inflow of water to see if it changes.

Pay attention to the change in water intake during the early stages of packing and printing. The water filling flow will change during the trial printing and after the package and printing are announced. While inspecting the samples for overlaps or water carriers, the water supply flow of the printing plate should be monitored.

Keep an eye out for any changes in water levels during the packing and printing processes. Keep a close eye on the main body of the equipment and the natural ventilation in the manufacturing workplace for water ingress to see if it causes any damage. While using the ethanol-dampening plate, adjust the temperature of the wetting liquid and cooling equipment in the wetting system software. If there is not enough water flowing into the printing plate, it will become unclean; if there is too much water, printing ink emulsion will form, causing a slew of problems. Faint print, retractable print paper, and a delay in the drying time of printing ink are a few examples.

3. Keep an eye on the ink replacement cycle.

The ink in the ink bucket line is critical. When the weight of the printing ink in the ink bucket line passes through the space between the roller and scraper, a natural extrusion occurs. As a result, the amount of printing ink in the ink bucket line has an instantaneous effect on printing ink production. Consequently. It is critical to keep a sufficient supply of printing ink on hand, so keep an eye out for it. Ink printing has the added benefit of being compressible. If it is left in the ink bucket line for an extended period, the fluidity will gradually decrease. As a result, it is sometimes necessary to mix the ink in the ink bucket line with an ink knife or printing ink mixing equipment. Related product:

Printing ink should not be allowed to dry on equipment. If the machine is turned off for an extended period, such as when eating or sleeping, the printing ink on the ink roller and the printing ink surface in the ink bucket line will be dry. It can be sprinkled on the area to prevent dryness. Keep an eye out for symmetry in the ink used in printing. The density of printed materials is affected by the flow of water, temperature, and speed of the printing equipment. The standard samples should be compared to this one regularly. Use ink with luminous spots as little as possible.

The pH of the wetting solution should be kept constant. Changing the pH of the wetting solution after the printing ink has been neutralized is simple. As a result, it is critical to monitor the pH value to keep the printing plate clean.

4. Take note of the dirt on the back of your hands.

Because of the long drying time of the ink, the thick graphic ink layer, and the high smoothness of the paper during printing, reverse-side dirt accumulates as a result of printing ink adhering to previously printed reverse-side ink.

5. Keep an eye out for overlapping shadows.

Superimposed images are caused by printing plates shifting the images they generate, resulting in two-way and triple-image shadows in printouts. Printing overlap can be caused by a variety of factors, including ink, paper, teeth, barrels, screen printing ink, printing speeds, and ink viscosity. Use one of the options listed below to determine the source of the problem and resolve it.

To begin, open and print again to ensure that the print quality is correct, as well as to test the paper pulling force and adjust the paper feeding mechanism, paper pressing wheel, and pressing components. Step 2 will determine whether the silk screen printing ink has sufficient holding power. Silkscreen printing with the new ink is a breeze. Avoid overtightening by following the tightening procedure step by step.

Check the operating pressure of the barrel lining as well as the printing on the packaging boxes.

Check to see if the printing paper is appropriate. Printing paper with wavy lines at its mouth, in particular, is prone to overlapping images, necessitating close inspection of the finished product. Reduce the viscosity of printing ink. Due to the high viscosity of the ink, it is difficult to separate the printing paper from the screen printing ink, causing the trailing tip to become unstable and cause overlapping. This additive can help to reduce the viscosity of printing ink.

The gripper is adjustable. The most common cause of overlap is a lack of tooth correction and care. As a result, it is critical that dental work such as adjusting, cleaning, and inspecting be completed on time.

6. Printing quality should also be checked at this point.

Run another 20 to 30 pieces of printed material through the machine, twisting the paper slightly after each run, and double-checking the front and side gauges to ensure proper positioning.(capable of performing two printing inspections).

7. Keep a close eye on the total number of copies.

Before completing the package printing process, the printing number will be compared to the packaging number. If there is a shortfall in supply, the production and manufacturing management will be notified, and the supplement will be provided as soon as possible.

8. Don't neglect other projects.

The act of putting ink and wetting liquid into a container. Work on two projects at the same time. Cleaning printing plates and screen printing ink is necessary because they collect dirt, such as leather residue, paper powder, and paper wool, and reflect it onto the printing paper. Most of the time, the equipment must be turned off before the dirt removal can begin. Unless special equipment to clean the machine while it is in use is available. It is forbidden to remove dirt during surgery.

Throw away used screen printing ink and erasers. If printing ink, paper powder, or powder spray powder is deposited on the silk screen printing ink, the machine should be stopped to prevent printing ink migration. Dispensing and editing will be safe as well.

Keep an eye out for printing equipment malfunctions. Keep an eye out for any irregularities in the operation of the printing equipment, as well as any noises or vibrations that may be coming from the machine.
