There are the following differences:

1. Different materials

The materials of the photo board can be: PP film, adhesive, photo paper, light box film, adhesive Mount ordinary boards, etc.; the material of KT boards is polystyrene (PS). PS particles are foamed to form a board core

2. Different image modes

Photo boards are The image is formed by inkjet printing uniformly using CMKY mode, and the image of the KT board is directly pasted from the photo screen.

3. Different fields of use

Photo boards are used for outdoor publicity, while KT boards are widely used in advertising display promotions, aircraft models, architectural decoration, culture, art and packaging, etc.

Inkjet printing can be roughly divided into two types according to different uses: one is outdoor advertising screen output, and the other is indoor advertising screen output. According to the type of ink used by inkjet printers, they can be divided into: water-based ink, eco-solvent ink, solvent ink, UV ink;

Inkjet printers with water-based ink are also called photo machines and are mainly used for indoor screen output. , eco-solvent, solvent and UV ink inkjet printers are mostly used for outdoor picture output. These three inks have the characteristics of anti-ultraviolet (not easy to fade outdoors).

KT board is a new type of material made of polystyrene (abbreviated as PS) PS particles that are foamed to form a board core and then surface-coated and pressed. The board body is crisp and light. , not easy to deteriorate, easy to process, and can be screen printed (screen printing board), painted, mounted with adhesive backing and inkjet printing directly on the board. It is widely used in advertising display and promotion, aircraft model, architectural decoration, culture, art and packaging, etc. .

Extended information:

Inkjet printing files are often very large. If the resolution of printing is used for large images, the computer will simply not be able to handle it, and it is unnecessary. For example, Photoshop cannot exceed 30,000 pixels for drawings. However, there is no rigid standard for inkjet printing resolution. The following are the resolutions used when making inkjet printing images of different sizes. For reference (the image area is square meters, you can make the drawing according to the following requirements):

400 square meters Meter or above (resolution: 10.16dpi) 4pixel/cm;

200-400 square meters (resolution: 12.7dpi) 5pixel/cm;

120-200 square meters (resolution Rate: 15.24dpi) 6pixel/cm;

80-100 square meters (resolution: 17.78dpi) 7pixel/cm;

60-80 square meters (resolution: 20.32dpi )8pixel/cm;

30-60 square meters (resolution: 22.86dpi) 9pixel/cm;

20-30 square meters (resolution: 30.48dpi) 12pixel/cm ;

Under 20 square meters (resolution: 38.1dpi or above) 15pixel/cm;

Note: When it affects picture splicing, the file needs to be cut, and the unit is pixel/inch. There will be errors when using integers, but when using pixel/cm units as integers, it is very accurate, because we are perfectionists.

Under normal circumstances, the photo resolution is 72dpi. If the file is too large (for example, the file size exceeds 400 MB when the actual size is displayed in the Photoshop menu, image/imagesize), the resolution can be appropriately reduced. The file size can be controlled within 400 MB.
