There are several formats for printing files. For example, what format is generally used for poster advertising printing? 1. The formats of printing files are: 1. PSD format is the inherent format of Photoshop. PSD format can open and save images faster than other formats. Good saving layers, channels, paths, masks and compression schemes will not cause Data loss etc. However, few applications support this format. 2. The BMP format is the inherent format of MicrosoftPain developed by Microsoft. This format is supported by most software. The BMP format uses a lossless compression method called RLE, which has no impact on image quality. 3. PDF format PDF (Portable Document Format) is a file format created by Adobe Systems that allows electronic documents to be viewed on the screen. PDF files can also be embedded in HTML documents on the Web. 4. JPEG format JPEG (abbreviated from Joint Photographic Experts Group, meaning Joint Graphics Experts Group) is the most commonly used image format we usually use. It is the most effective and basic lossy compression format and is supported by most graphics processing software. JPEG format images are also widely used in the production of web pages. If you don't have high requirements for image quality but need to store a large number of pictures, using JPEG is undoubtedly a good way. However, for image output and printing requirements, it is best not to use the JPEG format, because it improves the compression quality by damaging the image quality. 5. The GIF format is the most commonly used format for outputting images to web pages. GIF uses LZW compression and is limited to colors within 256 colors. The GIF format is represented by two codes: 87a and 89a. GIF87a strictly supports opaque pixels. GIF89a can control which areas are transparent, therefore, reducing the size of the GIF even more. If you want to use the GIF format, you must convert to indexed color mode (IndexedColor), so that the number of colors is converted to 256 or less. 6. TIFF format TIFF (TagImageFileFormat, meaning tagged image file format) was developed by Aldus in the early days of the Mac The purpose is to standardize scanned images. It is the most widespread image printing format across Mac and PC platforms. TIFF uses LZW lossless compression, which greatly reduces image size. In addition, the most exciting feature of the TIFF format is the ability to save channels, which is very beneficial for you to process images. 7. The cdr format and AI format are vector file formats. It is worth noting that files between different versions of corelDRAW cannot be used universally, while illustrator does not have this limitation. 8. EPS format is a format between vector and bitmap images and is widely used in the printing industry. 9. WMF format: It is a mixture of bitmap and vector graphics and is widely used in the field of graphic design. 10. PCD format: It is a special storage format for PhotoCD. It is generally found on CDROM material discs. PCD files contain images of various resolutions from professional photography to ordinary display. Courseware can generally be reduced to a pixel size of 640×480. . 11. TGA format: It has a simple structure and is easy to convert to files in other formats. Supports 8-bit to 32-bit color depth. 32-bit images include an 8-bit alpha transparency channel. This format has been widely used in the field of computer professional video. 2. Poster advertisements are printed with TIF format images. Although the files are large, the printed posters are more realistic. The color mode of the picture must be cmyk, otherwise serious chromatic aberration will occur. This is because the poster printing factory's machines are CMYK four-color printing. When designers deliver files for printing posters, it is best to click on the image to check whether the image mode is cmyk, and then save it in PSD format. The poster printing factory's resolution requirements are 300 pixels/inch for small posters and 80 pixels/inch for large posters. What format should posters made with PS be saved in before they can be printed?
TIF format allows the original information of the photo to be preserved more abundantly.

Extended information
TIFF, together with JPEG and PNG, has become a popular high-bit color image format.
The TIFF format is widely supported in the industry, such as Adobe's Photoshop, Jasc's GIMP, UleadPhotoImpact and PaintShopPro and other image processing applications.
Desktop printing and page layout applications such as QuarkXPress and Adobe InDesign, scanning, faxing, word processing, optical character recognition and other applications all support this format. Dobe, the company that acquired the PageMaker printing application from Aldus, controls the TIFF specification to this day (2014).
The term "TaggedImageFileFormat" or "TagImageFileFormat" existed as a subtitle in some early TIFF specifications. The 2014 TIFF specification TIFF6.0 no longer uses these terms and is just called "TIFF".
The TIFF file format is suitable for exchanging files between applications and computer platforms. Its emergence makes image data exchange simple.
-What is the TIFF (Image File Format) poster format?
The general format of a poster is as follows:
Posters generally consist of three parts: title, body and signature. composition.
1. Title:
1. It consists of the name of the genre alone. Now write the word "Poster" in the middle of the first line.
2. The topic will be directly determined by the content of the activity.
3. It can be some descriptive text.
2. Text:
1. The purpose and significance of the activity.
2. Main items, time, location, etc. of the activity.
3. Specific methods of participation and some necessary precautions.
3. Signature:
Sign the name of the organizer (poster issuance date).
Notes on poster writing:
(1) Write down the location, time and main content of the event in detail and truthfully. You can use encouraging words, but don't exaggerate the facts.
(2) The text of the poster is concise and clear, and the length is short and concise.
(3) The poster layout can be artistically processed to attract readers.
