2, the scope of application is different: inkjet is mostly used for outdoor advertising, enclosure and so on. ; Portraits are often used to make some indoor pictures, such as Yi Labao and X-frame, and can also be used as background. However, if a large area needs to be spliced, it can also be painted with cover plate, KT plate or cold plate.
3, different practicality: the price of inkjet printing is cheap, the usable area is large, there is a pungent smell, and the picture accuracy is slightly poor; The photo has high accuracy and no peculiar smell, but the price is higher than that of inkjet printing.
4. Use different membranes; Kt board is a very thin ps film attached to both sides of ps foam board.
The bright board is usually an ordinary board, and this is a special pm film, which is very bright. The resolution is also higher and the pixels are higher.
5, image mode requirements:
Ink-jet printing uses CMYK mode uniformly, and RGB mode is prohibited. Nowadays, inkjet printers are all four-color inkjet printers, and the color and printing color are completely different. Of course, when drawing, they should follow the printing standards.
Photos can be in CMYK mode or RGB mode. It is best to use CMYK mode. Note that the value of red in RGB is defined by CMKY, that is, M= 100 Y= 100.
Extended data;
Outdoor attention;
Ultraviolet (UV) is the number one killer of images, especially inkjet images. Unprotected dye ink inkjet images will fade in less than a day in the sun. There are three ways to deal with ultraviolet rays: use good quality ink and substrate, and use pigment ink if possible; Glued anti-ultraviolet film; Choose a place where there is no direct sunlight and turn over the chart.
Rain and moisture will wrinkle the image. The key to prevention is gluing. When gluing, make sure the perimeter is sealed. Ink-jet paper absorbs water like the sea surface, and a little gap will make a big mistake, especially when cutting pictures, because water will make the ink disperse, thus destroying the image quality.
Environmental pollution is also the enemy of beautiful image. Motor vehicle exhaust will also damage the image, corrode the covering film, and easily damage the image. One of the solutions is to cover the image with high quality film.
When the temperature is below 100 degrees and zero degrees Celsius for too long, images will always appear, so special attention should be paid to handling them. If the temperature is too low, the image will crack, if it is too hot, the film of the image will fall off or the communication hall will be soft, making the image unclear. It is suggested that the image made of polyester film is better than that of vinyl film at high temperature.
