Conventions for Naming Files in Prepress Production
The following is a recommended format for naming files
(Publishing date) (Advertiser's name) (Sequential letter) (Version number)
The publication date is the date on which the ad page or insert page enters the newspaper. It consists of four numbers, the first being the month and the second being the date. For example, "0914" refers to September 4. For multiple inserts, use the same date.
The advertiser's name cannot have punctuation. For example: Joe's Tires should be abbreviated as Jtires.
The sequential letters are used to identify different ads or inserts from the same advertiser. Using the letters A through Z, sequential labels can be used on each ad if advertisers do several ads or inserts at the same time. For example: 0904JTiresA1 refers to an advertisement, and 0904JtiresB1 refers to the second advertisement.
The version number is used to identify the changes in the original advertisement and insert. It is a number. For example: 0904JtiresB1 refers to the first version of an ad, 0904JtiresB2 second version.
Do not use punctuation in file names.
For a file name limited to eight bytes, the first four bytes are used to indicate the publication date, and the last four bytes indicate the advertiser's name, order letter, and version number, respectively.
The file extension must be able to indicate the file format. For example: 0904JtiresB2.EPS indicates that the file format is EPS.
Last check
Make sure that all colors are ready for CMYK color separation and remove unused colors from the palette.
Remove all external information from the clipboard and remove unprintable objects from the digital file.
Clear all job package contents and foreign information from digital files.
Ensure that all pages are the correct size and the page margins are zero.
When storing the final page or ad page, try to use the "save as" command. In some packages, this will create a cleaner, more compact file.
Store all pages, photos, and graphics in a home folder and create a separate font folder in that folder. The entire folder is packaged with archive software and delivered via a removable storage carrier or electronically.
Verify that all the correct files required for the print are contained on the provided storage carrier, such as linked graphic files, borders, and lines.
Clearly socialize with printers or newspapers for all information about file styles. (Using the file naming conventions mentioned above) All content of the file style is also indicated on the content sample.
Make sure that the page or ad file can be stored on a disk or film. Do not use multiple disks to store these pages or advertisements.
Write the prepress and preflight information of the file on the disk surface to ensure the correct result. Similar information can be stored in a simple text file and submitted with the digital file. You can find sample forms that fill out this information on the industry website.
Back up your files before submitting them.
Write the name and telephone number of the contact on the label disk and the name of the file.
Inform printers and newspaper companies of any potential compatibility issues caused by program upgrades, such as extensions, plug-ins, and accessories.
Image file compression
Compress images or ad files to increase transmission speed and reduce file storage requirements. There are two types of file compression: "lossless" and "lossy".
Lossy compression combines similar or identical data, resulting in loss of the original data in the final decompressed file. The most commonly used image compression type in the printing industry is JPEG (Joint Photographers Expert Group). The larger the "loss" value of the compression settings, the more dissimilar information will be summed up in the same value. The substantial compression in the lossy type will result in a drop in image quality, a great influence on the details of the image, and a "hand-processed" feeling in the delivery process.
The ratio of file compression should not exceed 10:1, which is usually a low compression/high quality setting. However, even at a compression ratio of 10:1 or less, repeated compression and decompression will result in a decrease in image quality. For example: an image that has been compressed into a JPEG format is decompressed, edited, and then compressed into JPEG format again; a compressed image is decompressed for design, and finally stored in PDF format, which also results in recompression. This repeated compression/decompression cycle may result in more quality loss.
Lossless compression combines only equal values, so the image is decompressed without loss of quality. Examples of lossless compression include: Zip and LZW formats, and their compression ratio is 3:1.
The transmission of digital files does not require data compression, but data compression can speed up the transmission of large files. Only when the transmitting and receiving parties agree on the compression method can the data be compressed and used to transfer files.
Here are some detailed guidelines for using compression software:
The degree of compression will affect the quality of the image. Do not use compression ratios greater than 10:1. It is best to perform pre-tests to determine the compression method.
Usually, the receiver is required to have the same software tools as the transmitter so that the decompression process can be completed correctly.
Do not split files during compression.
There are some commonly used compression application software that negotiates with the printer or newspaper company which application software to use.
Both the compression and decompression processes require considerable time and power for the computer. However, this is worthwhile because the smaller advertisement files that the network can handle can be obtained through compression, thus reducing the delivery time.
If the application software can control the degree of JPEG compression, the black and white photos are set to "best quality" and the four-color images are set to "high quality." This setup not only gives the advantage of compression, but also guarantees high
The quality of the copy effect.
Usually the PDF software has its own compression feature. It is best not to use PDF software when compressing PDF files again.
file transfer
There are many ways to pass digital files to printers or newspaper companies. Some are as simple as submitting a disk. But for long-distance, short-term print, this method becomes very impractical. Modems, telephone lines, bulletin board systems (BBS), the Internet and other electronic means can easily and quickly transmit advertising documents. There is also a special service for exchanging digital files for advertisers and newspaper offices. This service makes the delivery of digital files easier.
There are many methods and software tools for transferring digital files. By following the above guidelines, you can prepare the final document and pass it to the printer or newspaper office. For guidelines on transferring and receiving files, see the description of the hardware and software used.
Here's how to simplify delivery and reduce costs:
be prepared. Make sure all materials are ready before transferring documents. This will prevent unnecessary telephone line occupation and reduce the cost of transmission.
Use the compression method described above.
With a faster modem, the faster the modem, the shorter the file transfer time. Ask the printer or newspaper office about their operating speed.
If there are many packets that need to be resent, let the telephone company check the line conditions. A lower quality telephone line will reduce the effective speed of the modem.
Do not delay. Do not turn off the modem or computer at the place of origin to interrupt the modem connection, as this will increase the difficulty of the receiver's operation.
Before sending a file larger than 3MB, call a printer or newspaper to verify that there is sufficient storage capacity at the receiving site. This can also alert the recipient of pending files.
Check all files for viruses before transmission. Even if the receiver will check, it is a bad ritual to send unchecked documents.
Leave extra time for re-sending. There are many reasons why the file needs to be re-sent, such as noise on the phone line, disconnection, and so on.
Use the correct protocol. Verify the transmission technology agreement that printers or newspaper publishers may use

A BBQ grill mat is a non-stick mat that can be placed on top of a grill to prevent food from sticking and falling through the grates. It is typically made of heat-resistant materials such as PTFE (polytetrafluoroethylene) or silicone. The mat creates a barrier between the food and the grill, allowing for easy flipping and preventing flare-ups. It also helps to distribute heat evenly and can be used for cooking a variety of foods, including vegetables, fish, and delicate items like eggs or pancakes. The BBQ grill mat is reusable, easy to clean, and can be used on gas, charcoal, or electric grills.
