Defining the page size

PRISMAprepare creates any missing PDF boxes when you open a non-page programmed

document in PRISMAprepare for the first time:

1. If no trim box is defined, but a bleed box is defined, then the trim box receives the size of the

bleed box.

2. If also the bleed box is undefined, but a crop box is defined, then the trim box and bleed box

receive the size of the crop box.

3. Finally, if also the crop box is undefined, then the trim box, bleed box, and crop box receive

the size of the media box. The media box is always present in a PDF page.

The following size rules apply:

[Media box]

> [Crop box] > [Bleed box] > [Trim box].

Changing the PDF boxes automatically and manually

• PRISMAprepare changes the trim box automatically when the page size changes.

• PRISMAprepare automatically maintains the relations between the PDF boxes according to the

size rules.

[Media box] > [Crop box] > [Bleed box] > [Trim box].

• The operator can change the PDF boxes manually.

For example, when you assign a smaller media to a page, you can select to reduce the page size.

Now, PRISMAprepare automatically modifies the trim box. PRISMAprepare does not modify the

trim box when you assign a larger media without changing the page size. If required, the operator

must manually modify the other PDF boxes.

Print the content of a PDF box

By default, the content of the bleed box is printed when the document contains a bleed area,

otherwise the content of the crop box is printed.

You can change which content must be printed in the [Layout] tab of the [Production] workspace.

In this tab, you can select which PDF box must be printed.

Unique settings for the [Trim box]

The size of the trimmed page. The trimmed page contains the page content. For each page, the

trim box is equal to the page size. In theory, the page size can be different for each PDF page.
