What format is the poster printed? Is the poster exported as pdf or png?

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 format should the poster made by ps be saved in before it can be printed in TIF format, so as to save the original information of the photo more abundantly.

Extended data

TIFF, together with JPEG and PNG, has become a popular high-bit color image format.

TIFF format has been widely supported in the industry, such as Adobe's Photoshop, Jasc's GIMP, UleadPhotoImpact, and PaintShopPro.

Desktop printing and page layout applications such as QuarkXPress and AdobeInDesign support this format in scanning, fax, word processing, optical character recognition and other applications. _dobe Company, which obtained the PageMaker printing application from Aldus, has controlled the TIFF specification (20 14) so far.

The term "tag image file format" or "tag image file format" existed as a subtitle in some early TIFF specifications. TIFF specification TIFF6.0 of 20 14 no longer uses these terms, but is just called "TIFF".

TIFF file format is suitable for exchanging files between application programs and computer platforms, and its appearance makes the exchange of image data simple.

Use pdf when exporting posters or use pdf when exporting png.

When printing posters, the best file format should be pdf file format. Although there is no compressed file in png file format, its document size will be very large to meet the needs of large-format posters, while the file in pdf file format itself is used to print or make large-format pictures.
