Image-Based Perforated Pattern For Architectural Sheet Metal Design

There are many types of holes, including round, square, hexagon, rectangle, triangle and rectangle, and there are several possible punch patterns.The most common patterns in traditional perforated sheet metal are linear patterns and staggered patterns.In a line pattern, the arrangement of holes can be determined by two parameters, vertical and horizontal.To create a square pattern, the distance in both directions should be equal.If the distance in the vertical direction is different from the distance in the horizontal direction, the perforated pattern will be called a rectangular pattern.Unfortunately, compared to the staggered pattern, this line pattern is not as strong as the staggered pattern due to the nature of the layout.In addition to all of these uniform and traditional perforated metal patterns, new image-based perforated patterns have also become widespread.This opens up a new exciting market opportunity for any perforated sheet metal project, which is good for both suppliers and customers.Basically, the punch pattern is generated by capturing the color of the image using a specific calculation/algorithm, and then, all the information is translated in a complex way, designed to create a pleasant perforated pattern that somehow reflects the original image.When designing perforated sheet metal patterns based on images, there are several considerations.It is recommended to consider these factors so that the perforated pattern design reflects the original image as much as possible and reflects the pattern the designer wants.More hole types are better and more hole changes may give better results.In most cases, this is simply because the more holes are used, the greater the information captured during the conversion process to generate a perforated pattern.A perforated piece pattern design with a good proportion of the image and the perforated piece should be proportional to the original image.If the size of the original image is not proportional to the perforated piece of the design, the designer will be forced to stretch the perforated pattern.This can be intentional in some cases, but in general, this should be avoided if you want to create a natural perforated pattern design that reflects the original source.The original image composition although almost any image can be converted into a perforated metal pattern design, the color composition of the image plays an important role in obtaining the best results.In most cases, images with strong contrast and vivid color separation appear to capture better in the perforated paper pattern conversion.For example, a cartoon image or a painting in Andy Warhol style is best suited for a perforated conversion.The most difficult one is the image photo with smooth color transition and smooth light contrast.bright colour.Observe the distance to get the best representation of the pattern punch, design a better punch pattern, and make the pattern best reflect the original image, designers should consider the viewing distance between the perforated panel item and the person who will see it.Observed distance is associated with mean hole size and centerto-The center distance between the holes and the open area.Therefore, if a perforated pattern can be seen at a distance of about 10 m (e.g., a parking building sign), at this optimal viewing distance, they will automatically identify the image that appears on the perforated paper.However, when people see it at a distance of about 3 or 4 metres, they see the perforated pattern as a scattered, meaningless hole pattern on the paper..On the other hand, if people see it from 20 or 25 metres away, they will treat it as a point image or a normal picture without automatically knowing that it is an art work created by a perforated pattern.The picture below shows what people will see when the perforated pattern design is too close or too far away.Lighting arrangement for better resultsBased on the protruding perforated metal, we should consider using the backlight to better represent the original image.Lighting from natural light (E.G.Sunlight or artificial light (suchSpotlight) plays an important role in creating better composition to improve the visual effect of perforated patterns.Placing bright light behind the perforated sheet creates a perforated shadow, which can be more complicated for the perforated pattern.According to my last perforated project, creating a 3D perforated pattern project before manufacturing is a recommended project, before manufacturing, all perforated pattern designs are visualized as 3D designs by using third-party 3D CAD software.By doing so, designers and project owners can deliberately check to see if all design considerations, including the color, texture and arrangement of light, are available, and the design of the perforated sheet pattern has been adapted to their specifications.All in all, the product transformation at the design stage is much cheaper than making real products.
