Because PSD/PDD is a special format of Adobe's graphic design software Photoshop, PSD files can be stored in RGB or CMYK mode, and the number of stored colors can be customized, and information such as layers, channels and paths of Photoshop can also be saved. Is the only format that can support all image color modes at present.
PSD format compresses files to reduce disk space when saving, and PSD files retain all original image data information for easy modification.

Matters needing attention in pattern printing:
1. Pay attention to the selection of materials when printing posters, because materials are related to the overall quality and can better show the printing effect. It is basically the choice of paper and ink. Paper mainly pays attention to thickness and grams, while ink is the characteristic of ink printing.
2, poster production is to pay attention to its outdoor exposure time, to choose printed materials. There are also printing companies to communicate with customers and print poster printing products that customers are satisfied with.

There are several formats for printing documents. For example, what format file is the poster advertisement printing? 1. The format of the printed file is: 1. PSD format is the inherent format of Photoshop. PSD format can open and save images faster than other formats, and well save layers, channels, paths, masks and compression schemes without data loss. However, few applications support this format. 2.BMP format is the inherent format of MicrosoftPain developed by Microsoft, which is supported by most software. BMP format adopts a lossless compression method called RLE, which will not affect the image quality. 3.PDF PDF(PortableDocumentFormat) is a file format created by AdobeSystems, which allows electronic documents to be viewed on the screen. PDF files can also be embedded in HTML documents of websites. 4.JPEG JPEG (short for Joint Graphic Experts Group) is the most commonly used image format. It is the most effective and basic lossy compression format, which is supported by most graphics processing software. JPEG images are also widely used to make web pages. If the image quality is not high, but you need to store a lot of pictures, then using JPEG is undoubtedly a good way. However, it is best not to print images in JPEG format, because it improves the compression quality by impairing the image quality. 5.GIF format is the most commonly used format for outputting images to web pages. GIF adopts LZW compression, and the color is limited to 256 colors. GIF format is represented by 87a and 89a codes. GIF87a strictly supports opaque pixels. GIF89a can control the transparency of those areas, thus greatly reducing the size of GIF. If you want to use GIF format, you must switch to IndexedColor mode so that the number of colors is 256 or less. 6.TIFF(TagImageFileFormat) was developed by Aldus in the early days of Mac to standardize scanned images. It is the most widely used image printing format on Mac and PC platforms. TIFF uses LZW lossless compression, which greatly reduces the size of the image. In addition, the most exciting function of TIFF format is to save channels, which is very beneficial for you to process images. 7.cdr format and AI format are both vector file formats. It is worth noting that files between different versions of corelDRAW cannot be universal, and illustrator does not have this restriction. 8.eps format is a format between vector and dot matrix images, which is widely used in printing industry. 9.WMF format: It is a mixture of bitmap and vector diagram, and is widely used in the field of graphic design. 10, PCD format: It is a special storage format of PhotoCD, which usually exists on CDROM. PCD files contain images with various resolutions from professional photography to ordinary display, and courseware can generally be reduced to the size of 640×480 pixels. 1 1, TGA format: simple structure, and can be easily converted with other formats. It supports 8-bit to 32-bit color depth, and 32-bit images include 8-bit alpha transparent channels. This format has been widely used in the field of computer professional video. Second, poster advertisements are printed as pictures in TIF format. Although the file is relatively large, the printed poster is more realistic. Moreover, the color mode of the picture must be cmyk, otherwise there will be more serious color difference. This is because the poster printing machine is cmyk four-color printing. When the designer delivers the printed poster file, it is best to click on the image to see if the image mode is cmyk, and then save it in PSD format. Poster printing factory requires small posters with a resolution of 300 pixels/inch and large posters with a resolution of 80 pixels/inch. What is PSD Source File Noun Explanation Editing PSD is a commonly used graphic design format, which can be stored in RGB or CMYK mode, and the number of colors can be customized and stored, and information such as layers, channels and paths of Photoshop can also be saved. Is the only format that can support all image color modes at present. PSD material is a source file that can be edited repeatedly, and it is a commonly used material format in China. PSD is the source file format of Photoshop. 2. Material introduction and editing material classification. PSD materials generally include culture and art, background, exhibition board design, album design, business finance, business cards, cartoons, sliding door design, design elements, real estate, festivals, lace corners, invitations, encyclopedia of life, logos, menu recipes, natural ecology, web design, packaging design, and people's pictures. Advertising posters and other aspects of the material [1] material download PSD general material is used more, there are many download sites in China, here are a few good sites for everyone to choose from. Big picture network: very good free PSD material, the overall material is comprehensive, and the quality of the website material is very high. Nitu. Com: It is a complete material website in China, and it should be the largest material website in China. Unfortunately, this is a paid website. Love map. Com: An established design website, an excellent design material website and a website frequently used by 4 million designers. Material China: It's an old material website, but the search is not very easy to use. Dad: It's a new website for charging materials. The fees are relatively high, and there are materials all over the world. An old material website is ok, but the interface is not very good. Siyuan Forum: An excellent forum for materials. There are many materials for photo studio and PSD design, but the search is not very easy to use. Baituhui: A good forum for design materials. The materials in the forum mode are also difficult to search. It is difficult to introduce 3-format PSD-PSD-Photoshop document(PSD), which is a special format of Photoshop, the image processing software of the famous Adobe company. This format can store all layers, channels, guides, notes and color patterns in Photoshop. When saving an image, if it contains layers, it is usually saved in Photoshop(PSD) format. PSD format will compress files to reduce disk space when saving, but it contains more image data information (such as layers, channels, clipping paths, reference lines, etc.). ), so it is much larger than other image files. Because PSD files retain all the original image data information, it is convenient to modify, and most typesetting software does not support PSD format files. Psd format file is a graphic file format, so it can be opened by drawing software such as ACDSee or graphic processing software such as AutoShape, AutoSpeed and PhotoShop.
