Poster advertisements are images printed in TIF format. Although the file is large, the printed poster is more realistic.

And 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 submits the document for printing the poster, it is best to click on the picture to see whether the picture mode is cmyk and saved as PSD. Poster printing factory requires 300 pixels/inch for small posters and 80 pixels/inch for large posters.

Extended data:

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

TIFF format is widely supported in the field of image processing, such as AdobePhotoshop, JascGIMP, UleadPhotoImpact, PaintShopPro, etc.

Desktop printing and page layout applications, such as QuarkXPress and AdobeInDesign, support scanning, fax, word processing, optical character recognition and other applications in this format. Adobe acquired the PageMaker printing application from Aldus and has been controlling the TIFF specification (20 14) ever since.

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

TIFF file format is suitable for file exchange between application programs and computer platforms, which makes the exchange of image data easy.
