If the book has a large volume, then the inner margins should be much larger than the outer margins. We received a book with over 600 pages. The customer sent a PDF file ready for printing. But there is one catch - the internal fields are not large enough. They must be increased due to external fields. How to do it?
Open PDF in Acrobat. Go to Document - Crop pages (Crop pages).
We find Change page format (Change Pade Size) (slightly at the bottom of this panel). Our page parameters are A4 (210 by 297). We need to increase the internal margins by 1 cm and reduce the external margins by the same 1 cm, taking into account even and odd pages.
We set custom file sizes - 220 by 297 (that is, the width was increased by 10 mm). Uncheck the box for Centered. On the right, we set the range of pages to which this should be applied: All, Only even pages.
It should look like this (even ones are larger, odd ones are smaller, we have not worked with them yet):
Working with odd ones: We set the custom file size - 220 by 297, uncheck the “Centered”, set the offset of 10 mm on the X scale, select the page range (All, Odd pages only).
We now have it like this:
Margins are different, taking into account even and odd pages. The internal field is increased by 1 cm everywhere.
In Master PDF Editor, you can create documents with pages of various sizes by reducing/enlarging a page or cropping it.
To reduce/enlarge the size of one or more pages, select from the main menu Document > Page Sizes or press keyboard shortcut Ctrl+Shift+L.
In the dialog box Page layout specify the page size, content size, and define the range of pages to change.
On the left side of this window is the page preview area, and on the right side are the layout settings. Values are presented in one of the selected units:
- Items
- inches
- millimeters
Drop-down list Units allows you to select one of them.
Page Size (MediaBox)
In this part, you can set the page size.
- Left And On right determine the width of the page
- Above And Bottom determine the height of the page
To change the page format, change the values in these fields.
In this part (if enabled) you can set the margins of the internal content of the page. By default, fields are disabled and set to zero. When Content Size enabled, non-zero margin values allow you to trim page content that does not fit within the specified margins.
There is a second, more visual way to crop a page or pages. It is described below.
When you finish editing the page layout, select the pages to which you want to apply this layout: just the current page, all pages in the document, or a specified range. You can also apply the selected settings to only even or only to odd pages, which is useful if the layout of the pages differs depending on their position on the spread.
Click OK to apply the changes to the document.
Page crop
To crop a page, select Document > Page Crop or click ctrl+K.
The mouse cursor will change to a crosshair, indicating that a crop area needs to be marked. Designate a rectangular area in the viewport that encloses the page content you want.
After selecting the cropping area, a window will appear. Page layout.
Here you can edit the crop zone by specifying the coordinates of the fields. You can also edit the page size.
In chapter Page Range specify to which pages the selected crop zone should be applied: all, current, even or odd pages, or a specified range of pages.
When finished, press the button OK to complete the crop. All specified pages will be cropped according to the designated area.
Cropping a page only changes the size of its content as it appears in the document, but the page size of the document remains the same. You can place temporary objects in the area of the document that is not displayed.
Trimming pages does not change the file size because the trimmed information is simply hidden, not removed. Therefore, you can restore original dimensions page and all the information located on it by unchecking the item Content Size.
File size reduction question pdf format often set by an active computer user. Due to the large weight of the scanned images. Because of this, the document takes up hundreds of megabytes of disk space. Let's consider the problem in more detail.
With Adobe Reader
You can reduce the document size with free version Adobe software Acrobat Reader. The compression feature is only available at checkout paid subscription. The utility is installed without problems, so let's get to work right away.From the start menu, go to the “File” tab. Click on the “Open” item and select the document. IN this example we will use a textbook weighing 69.9 MB. It consists entirely of scanned pages of the printed edition. You can also open a document by clicking on it. file manager. Go to the menu shown in the screenshot.
We leave the default values in the called window. Choose a location to save the compressed pdf. The example file now weighs 33.3 MB. Compression was performed for about two minutes. The image quality has deteriorated. On a website or computer, this may not be noticeable. However, after printing, the illustrations will be fuzzy or completely blurry. The disadvantage of this method is that there is no flexible setting for an advanced user.
If installation is required additional options, the optimizer will help. We open the document we need. Click on the button shown in the illustration below.
There are few settings, but they look difficult to master. Let's define the main ones. They are located in the left menu "Images". Downsampling determines the resolution of images. To the right of the parameter, you can set ppi (number of pixels per inch). Highly recommended for printing. It is advised when placing illustrations on the site. Below you can set the type of compression. ZIP is used for simple images dominated by one color. JPEG - for any images. Its improved version is JPEG2000.
After setting, choose a location to save the file. Let's compare the quality of the optimized document and the original. Left - original file, right - compressed.

Their names speak for themselves. High-speed less time-consuming, also having a low compression ratio. The maximum has the opposite characteristics.
Documents are added from the Files tab.
The compression of the file from the example took several seconds. The file weight has changed from 69.9 MB to 68.3 MB. Conclusion: WinRAR does not work well with pdf files. Plus program - the original is preserved unchanged.
Using the online service ILovePdf

The result is similar to the result PDF applications Compressor. The difference is that you do not need to download or install anything. Compare quality.

In conclusion, archivers do not work well with PDF documents, A best method compression is online services and the standard Adobe tool.
