Crop marks

Aspose.PDF Product Family
1

Hello,

I am using Aspose.Pdf to dynamically create business cards for a client. As these cards will be professionally printed they need to include crop marks (such as these). Can the component produce these automatically, and if so, how? I’ve tried using the BleedBox property but this doesn’t seem to have any effect on the document.

How to add printer marks manually:

// 1. Add margins on each side of the page, so that marks will be visible
var editor = new PdfFileEditor();
editor.AddMargins("input.pdf", "temp.pdf", new[] { 1 }, 36, 36, 36, 36);

using (var document = new Document("temp.pdf"))
{
    var page = document.Pages[1];
    var mediaBox = page.MediaBox;

    // 2. Set Page.TrimBox and Page.BleedBox not to include margins. The printer marks are placed between the MediaBox and these boxes
    page.TrimBox = new Rectangle(36, 36, mediaBox.URX - 36, mediaBox.URY - 36);
    // The BleedBox is usually slightly larger than the TrimBox
    page.BleedBox = new Rectangle(34, 34, mediaBox.URX - 34, mediaBox.URY - 34);

    // 3. Add trim mark in the corners of the TrimBox
    page.Annotations.Add(new TrimMarkAnnotation(page, PrinterMarkCornerPosition.TopLeft));
    page.Annotations.Add(new TrimMarkAnnotation(page, PrinterMarkCornerPosition.TopRight));
    page.Annotations.Add(new TrimMarkAnnotation(page, PrinterMarkCornerPosition.BottomLeft));
    page.Annotations.Add(new TrimMarkAnnotation(page, PrinterMarkCornerPosition.BottomRight));

    // 4. Add bleed marks in the corners of the bleed box
    page.Annotations.Add(new BleedMarkAnnotation(page, PrinterMarkCornerPosition.TopLeft));
    page.Annotations.Add(new BleedMarkAnnotation(page, PrinterMarkCornerPosition.TopRight));
    page.Annotations.Add(new BleedMarkAnnotation(page, PrinterMarkCornerPosition.BottomLeft));
    page.Annotations.Add(new BleedMarkAnnotation(page, PrinterMarkCornerPosition.BottomRight));

    // 5. Add color registration targets on all sides of the page
    page.Annotations.Add(new RegistrationMarkAnnotation(page, PrinterMarkSidePosition.Top));
    page.Annotations.Add(new RegistrationMarkAnnotation(page, PrinterMarkSidePosition.Bottom));
    page.Annotations.Add(new RegistrationMarkAnnotation(page, PrinterMarkSidePosition.Left));
    page.Annotations.Add(new RegistrationMarkAnnotation(page, PrinterMarkSidePosition.Right));

    // 6. Add the page information annotation in the bottom of the page, below the TrimBox
    var annotRectangle = new Rectangle(page.TrimBox.LLX, mediaBox.LLY, page.TrimBox.URX, page.TrimBox.LLY);
    page.Annotations.Add(new PageInformationAnnotation(page, annotRectangle));

    document.Save("output.pdf");
}

How to add printer marks in automated mode:

// 1. Add margins on each side of the page, so that marks will be visible
var editor = new PdfFileEditor();
editor.AddMargins("input.pdf", "temp.pdf", new[] { 1 }, 36, 36, 36, 36);

using (var document = new Document("temp.pdf"))
{
    PrinterMarkAnnotation.AddPrinterMarks(document, PrinterMarksKind.TrimMarks | PrinterMarksKind.BleedMarks | PrinterMarksKind.RegistrationMarks | PrinterMarksKind.ColorBars);
    document.Save("output.pdf");
}

You can explicitly specify rectangles

document.Pages[1].BleedBox = new Rectangle(10, 10, 590, 835);
document.Pages[1].TrimBox = new Rectangle(20, 20, 580, 825);
