7 Ways to Remove Wrinkles from AD Banners

In the advertising industry, what annoys clients the most? It was definitely a signboard that had just been made and the screen was wrinkled even after not being used for a long time.

This problem not only affects the professional image of the store in the minds of users, but also damages reputation in the long run, making the entire advertisement look very low. If the customer experience is not good, there is no hope of repeat customers, so advertising printers must pay attention to this “small” problem.

Next, I will take stock of several possible causes and solutions for screen wrinkles, and remind you to pay more attention.

1. Production professionalism

Production Professionalism

The degree of distortion is the most important factor affecting the flatness of the screen. A highly professional advertising and signage company will have more organized internal machines, back-end equipment and sample placement, and the relevant back-end equipment (such as glue binding machines, laminating machines, etc.) will also be relatively complete.

Billboards are generally produced and installed by businesses such as graphics shops or advertising companies. If the billboard picture and frame structure are defective during the initial production, not only will it be time-consuming and laborious to repair later, but it will also affect the aesthetics, flatness and durability of the inkjet cloth. If the advertising company needs frequent maintenance, it will even affect the in-depth cooperation between Party A and Party B.

2. Screen transportation and folding methods

When storing and transporting advertising screens, staff should try to roll the screens into a cylinder. If it cannot be rolled into a cylinder, multiple folding should also be avoided. Never fold the picture into a boxy shape, otherwise there will be many creases after opening, which will affect the efficiency of publication. Especially in cold weather, the creases will be more serious.

3. Screen stitching

Vertical splicing can minimize screen wrinkles. When splicing, the staff must stack the two pieces of cloth neatly before starting splicing. Uneven areas should be adjusted manually in time to avoid wrinkles on the picture to the greatest extent.

4. Picture design for cold season

When designing pictures in the cold season, designers should try to avoid designs with dark background colors and white patterns or text in the middle part. In order to make the inkjet cloth absorb ink better and faster, when the inkjet cloth passes through the printer, the ink sprayed on the screen will be preheated in advance. When the dark part of the material has more ink injection and the white part has less ink injection, the inkjet cloth will shrink unevenly and cause wrinkles after cooling.

This situation is more troublesome. It is difficult for workers to manually level the inkjet cloth. The final result is that there will be small wrinkles on the edge of the white pattern, just like washed banknotes, which greatly affects the appearance. The general way to solve this problem is to add part of the grayscale to the white pattern, 5-7 is enough, and increase the amount of inkjet in the white part. Adding a slight grayscale is difficult to detect with the naked eye and has minimal impact on the overall picture.

5. Truss structure

When building a truss, if the horizontal span exceeds 5 meters, a pillar needs to be added in the middle. Otherwise, a too long span will cause the middle part of the picture to be concave. Since the two ends of the picture are not on the same parallel line, no matter how straightened the picture is, wrinkles will appear in the middle part. In practical applications, this situation should be avoided as much as possible.

6. The shrinkage and extension time of the picture

During the installation process, you may notice that there are shallow creases on the screen, but they disappear when you look at them the next day. Why is this? The root of the problem lies in the effect of thermal expansion and contraction. Generally speaking, folded screens will have shallow creases when unfolded after being stored for 5 hours. Even after the crew smoothed the screen after installation, the creases remained. But after leaving the spray-painted cloth for a period of time, these creases will disappear naturally. When installing a large fence, although the screen may not be very smooth after the installation is completed, it will usually become smooth naturally in the second week.

7. Solution to Coated Banner screen wrinkles

  1. Pour boiling water on the back of the folds and pull them up and flatten: Remember not to directly scald the front of the picture, but the back of the picture, and be careful not to burn yourself.
  2. Use hot air from a hair dryer: If conditions permit, you can use hot air from a hair dryer to help eliminate wrinkles.
  3. Use force when installing: Be sure to use force when installing the Coated Banner screen. If possible, you can install it with the help of tools such as powerful pliers or flat-mouthed cloth pliers.
  4. For light box images: For light box images, be sure to pull the edge of the image hard to fix it. After turning on the light, it is equivalent to heating the screen, and the screen will naturally become flat within a few days.

Finally, when the weather is cold and humid, workers can spread the screen out in the sun to dry for a period of time before installing the billboard to allow the screen to warm up before installing it. This way, there will be no looseness in the picture the following summer.
