  • Lossy compression is to save the file by compressing the file size to be smaller than the original size. This will reduce the quality of the file as well, such as color quality, brightness and contrast, depending on how we choose to compress the file. (Compression) any type
  • Lossless compression is to save the file without compression to make the file smaller. Make the quality of the files the same as the original everything. But if there is a lot of data in the file It will make the size of the file larger as well.

The file will be larger or smaller. depending on the file added If it is to place the image directly into it It will make the file larger. But if adding an image file using a link, it will make the file size smaller, but the Adobe Illustrator .ai file cannot be printed. If you want to use it, you need to save the file as another file type like EPS or PDF before you can use it.

2.EPS (Encapsulated PostScript)

Will use the extension of the file as .eps. It is a file that contains both Vector and Bitmap data. The .esp file is different from the .ai of Adobe Illustrator in that when saving the file , there will be a boundingbox value indicating the file size. The file esp is ideal for transmitting print files because vector files are small and can be enlarged to the maximum resolution of the printer.

weakness

  • If the bitmap image is placed together with the vector, if the image is not high enough resolution Image enlargement time It will make the size of the image blur.
  •  It may take up to 1-2 hours to save the ESP file depending on the graphics work in the file. There is also a chance that the time printed does not match the screen you see.

3.PDF (Portable Document Format)

Will use the .pdf extension to save the file with necessary information, including fonts, vector data, or Bitmap images, so that when printing, you don't have to worry about the font being inaccurate or that the inserted image cannot be found. And it's also a small file. Make the time of sending prints convenient.

But in saving files should be careful about the settings. Because if selected as Default will make the size of the image smaller. spoil the quality of printing

4.PSD (Photoshop Document)

Will use the extension .psd, which is used in Adobe Photoshop . By saving the file, we can save everything that we do in the program. And the size of the file will increase according to the information contained in the file. The use of PSD files in Adobe Photoshop is commonly used to store original graphics. because it can be opened and run easily But if you want to save the file for printing, you have to save the file as TIF 8-bits/Channel first.

5.TIFF (Tagged Image File Format)

Will use the file extension as .TIF or TIFF. Saving files with this extension will save with Lossless compression, meaning there is no loss of quality of the file. The size of the file will be larger according to the size of the image used. Because it saves the file pixel by pixel if the file is very large. Can compress the file to a smaller size by selecting Save file , save the file as LZW-compressed. which the file will have a smaller size than before But it does not lose the quality of the file.

6.JPG (Joint Photographic Experts Group)

Will be used as the extension .jpg or .jpeg, which saves this type of file will be Save as Lossy compression is that the file has lost the quality of the file itself. jpg files are used for sending files with speed. easy to open But the quality of the file will deteriorate over time. Every time a new Save is opened and edited, so if a client receives a .jpg file from a customer, the new file should be saved as a TIF or PSD in Adobe Photoshop to keep it handy.

You can see that each type of file has been told all. will have different properties And the implementation is different too. before using the graphics file Therefore, we must ensure that we select the correct file type. in order not to lose the quality of the file.
