Can I print posters in pdf? Can PDF files be printed directly in the printing plant?

There are several formats for printing documents. For example, what format file is the poster advertisement printing? I. The format of the printed file is as follows:

1.

Photoshop document

Is the inherent format of Photoshop, PSD format can open and save images faster than other formats, and well save layers, channels, paths,

cover up

And the compression scheme will not cause data loss. However, rarely.

application program

This format can be supported.

2、

BMP format

MicrosoftPain is an inherent format 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 kind created by AdobeSystems.

Storage form

, allowing electronic documents to be viewed on the screen. PDF files can also be embedded in HTML documents of websites.

4、

JPEG format

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 use JPEG format for image output printing, because it improves the compression quality by damaging 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 convert it to IndexedColor, so the number of colors is 256 or less.

6、

TIFF format

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 between vector and.

Lattice image

This format is widely used in printing industry.

9.WMF format: bitmap and

vectogram

A hybrid of "Web" and "Web" is widely used in 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

Video field.

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.

Can PDF files be printed directly in the printing plant? Yes, PDF is a vector file and can be printed. I will open the print directly with AdobeIllustratorCS2!

Can PDF files be directly used for book printing? No, there are no color parameters in the PDF, so the printer can't recognize them. Color printing needs to be printed four times

+black, so it needs to be converted into color format, such as AI file. This is converted by the printing house in its own production process. Customers can provide PDF directly to the printing factory, with no special requirements.

Printing includes ink printing, dot printing, etc. But the definition of PDF is too low to print clearly.

Extended data:

At first, PDF was only regarded as a page preview format, not a production format. However, the market does not feel this way, and the market expectation has changed the focus of this format, thus changing the product. All kinds of e-book readers are flooding the domestic and foreign markets, and have replaced paper media in many fields.

The decline in the reading rate of paper media is largely due to readers turning their attention from paper media to e-books. Although the sales volume of e-book market is far from the traditional book market, it has a strong development momentum. Most e-reader manufacturers have started to support PDF format in whole or in part.

PDF e-readers widely used in the market include Dangdang mobile phone reader, Baidu of Zhangmen Technology, Reading in September of September Net, and development.

Special readers.

Adobe announced on July 13, 2009 that PDF/Archive(PDF/A) has been approved as a long-term storage format for electronic documents.

China National Standardization Administration Committee

Approved as a formal Chinese national standard, and officially implemented on September 1 2009. PDF file has become the de facto industrial standard of digital information.
