Overview of many aesthetic expression methods of modern packaging design (2)

Pay attention to the comparison of the packaging of similar products

Pay attention to the comparison of packaging design of similar products, which is an important part of packaging design. The design should clearly emphasize different points based on the above-mentioned points, ingenuity, and strive to design novel packaging with unique personality.

Judging from the trend of world packaging, the 30s and 40s tend to be uniform and cumbersome decorative effects, and in the 50s and 60s tends to simple, simple style. From the 1970s to the 1990s, a new momentum of development has emerged, and the form of decoration is more focused on changing and emphasizing loud advertising performance on a simple, crisp basis.

It goes without saying that packaging design, as a means of marketing products, must pay attention to the competitiveness of design and seek new changes. As for the traditional packaging style of certain products, there is no sudden change in the reform, and it is also in order to maintain its certain sales stability. Once this stability is shaken, it must be updated in a timely manner. Therefore, the form of packaging should pay attention to the comparison with similar designs and make a significant difference.

Pay attention to the diversity of formal means

When we watch a piece of packaging design, it is not simply visually accepted, but it must be accompanied by visual communication to produce a certain psychological response. This kind of psychology is called “vivid”, “noble”, and “exquisite”. The first depends on the objective condition of the object being viewed. This condition is not only the graphic and the color, but also includes the three-dimensional shape, material texture, structure style, and processing technology. These various factors together constitute a visual infection of a package design. force. If one of them is not handled properly, it will weaken the appeal. Therefore, in order to achieve the diversity of decorative beauty, form beauty, structural beauty, material beauty, and process beauty, designers are required to have multiple forms of processing methods, have certain knowledge about materials and fine arts, and strive to learn new information in real time. .

Resolution and size

The two issues of resolution and size are almost more confusing than anything else related to scanning and input. What is the role of resolution in digital images? What kind of input resolution should I use when scanning original drawings? How high resolution is enough to ensure high quality output? What kind of resolution is not too high? When is it best to resize the image and what method is best to resize the image? What is the resolution? and many more.

What is resolution?

If various terms in the field of digital imaging are regarded as actors, then in terms of versatility, "resolution" can win an Oscar. Whatever the "dress" and "role" of resolution, one of its most basic facts is that it is always used to describe the amount or density of digital information, so any discussion about resolution is inseparable from pixel and net. The relationship between grid characteristics, and the pixel and grid are the basic components of a raster device for a scanning device or an output device to reproduce. Now let's discuss the properties of pixels by placing the resolution in the digital imaging environment.

Pixel properties

The original grayscale or color photo has a continuous hue, that is, a smooth transition between adjacent colors or shadows, but the computer can not understand any continuous thing, the information is divided into individual units that can be processed, pixels The (graphical element) is the smallest unit that can be used to measure image data. The complexity of reproducing all digital images is to use these separate, discrete small elements to simulate continuous tones.

Each pixel in a raster image has four basic characteristics: size, hue, color depth, and position. These four attributes all help define the resolution from different perspectives.

Pixel size

All pixels in the same image are the same size. Initially, the size of the pixel is determined by the resolution used when the image is scanned, i.e., when the image is captured digitally. For example, a 600 ppi scanning resolution means that each pixel is only six hundredths of an inch. The higher the input resolution, the smaller the pixels, which means that each metric unit has more information and potential details, and the hue looks more continuous; the lower the resolution, the larger the pixel. The smaller the detail of each metric unit, it looks somewhat rough. The combination of pixel size and number in an image determines the total amount of information it contains. At any time during the production process, the pixel size can be changed by simply changing the resolution. If your output is used for printing, then changing the resolution automatically changes the size of the print.

Color or tone

A film or filmless camera assigns a color or grayscale value to each pixel in the image. When the pixels are small and the color or tone of the adjacent pixel changes little, it creates an illusion of continuous tone. . Images scanned using a device with a low noise figure and wide dynamic range exhibit a very natural continuous tone because they include a particularly wide tonal range from light to dark.

Tip: The detail in the image is a function of the pixel size and tonal range, the pixel size is directly related to the resolution, and the tonal range is determined by the dynamic range of the scanning device.

Color depth

A single pixel can only give it a value, and it is the bit depth or color depth of the digitizer that determines how many potential colors or shades can be assigned. Although each additional bit can increase the smoothness of the transition between adjacent colors and shades, it requires more file storage space.

Pixel position

A raster image is simply a grid of many individual pixels, each of which has a definable horizontal and vertical position within the grid. In most major image editing programs, the coordinate position of any pixel can be obtained by moving a tool called Eyedropper on the graph. The physical size of the grid is determined by the total number of pixels and the resolution, which in turn determines the relative position of each pixel.
